The Northern Hawk Owl is a medium sized owl that typically lives and breeds in the far north. They are rarely seen in south eastern Ontario unless factors such as a lack of food in their native habitat displaces them southward in search of a reliable food source. This winter a lone Northern Hawk Owl has shown up about an hours drive north west of us and it has become quite a celebrity with many birders and photographers making a point of seeing this locally rare bird.
I will prepare another blog post about the Northern Hawk Owl, however with this post I would like to highlight a behaviour that is fairly common amongst raptors; the practice of caching food for future consumption. Northern Hawk Owls are opportunistic diurnal raptors that take prey whenever it presents itself. Thus if the owl captures more food than its immediate nutritional requirements demand it will hide, or cache, that food in a safe place for later consumption. Typical spots for caching food are inside tree cavities or betweens forks of tree branches. It is a behaviour that I was aware of but had never observed until watching this Northern Hawk Owl. It was also a pleasure to be able to catch the caching process with the camera and I trust you enjoy the educational aspect of the images in this post.
The first step for the owl is to catch the prey. Northern Hawk Owls typically hunt voles and small to medium sized birds. The owl caught this vole outside of my view however returned with it to a nearby perch.
After catching its prey, the owl will often use its wings to spread out around the prey shielding it from the attention of nearby raptors and predators in a behaviour known as mantling. Although not a classic mantling example, you can see in the next image how the Hawk Owl has completely consealed (well, almost) its prey while on its perch.
After closely surveying the area and detecting no threats, the owl moved to its chosen cache site in the fork of a small nearby tree.
The Hawk Owl deftly and rather forcefully placed the vole into the crook of the tree trunk and branches.
Once the vole was securely placed and well hidden in the tree the Northern Hawk Owl repositioned himself on a nearby perch and immediately began hunting for its next catch.
It was interesting to observe that the owl, as well as looking for new food, also kept watch on the locations of its cached food sources. At one point the owl took flight from its perch and travelled about fifty yards to knock a large black squirrel out of a tree that was presumably getting too close to a cached vole. The squirrel fell about 40′ to the ground and didn’t seem to be harmed in the process. The Northern Hawk Owl returned to its original perch and continued to hunt, confident that the squirrel would leave the cache alone. Those of you who have been following this blog will notice two things; its been two years since the last post, and the website looks very differnt now compared to when you last saw it. The old website was so dated in its appearance that I was embarassed to post anything and athough not a good excuse, there just wasn’t enough free time to take the time required to learn how to create a new fresher looking website. Today’s version is better than the old one, however still requires lots of tweaking to get it to where it needs to be. If you find any bugs or have any design suggestions please feel free to leave a comment and I’ll do my best to make the improvements.
Happy New Year to everyone and I look forward to keeping in touch via this website, Facebook or Instagram.
The Survey Period Has Ended. Thank You For Your Interest.
Each year as the cold weather moves in and winter arrives, those of us who count ourselves as birders, photographers or a combination of thereof look forward to seeing owls, especially those that make their way south from the Arctic in search of food. In our area (Southern Ontario) the Snowy Owl is the most common followed by the Great Gray Owl and even more elusive Northern Hawk Owl.
It is also the time of year that the topic of discussion on many birding and photography forums as well as other social media platforms turns to the subject of baiting, specifically the baiting of raptors. These discussions are often emotionally charged and it has been my observation that little is accomplished by them.
If you search the literature there is not a plethora of information regarding baiting, especially with respect to the modes of baiting nor any objective parameters to even define what constitutes baiting. It is no wonder baiting discussions take the course they do.
The desire to gather information that will provide context for future baiting discussions became the genesis for this survey. It has been in development for a while and I greatly appreciate the input and edits suggested by five respected colleagues (including birders, conservationists and photographers) who reviewed the survey prior to its release.
The survey will remain open through January 31, 2018 with results available shortly afterwards. Please invite others to complete the survey and feel free to promote it among groups you interact with.
The Survey Period Has Ended. Thank You For Your Interest.
Last Saturday marked the last day of 2016 and although very overcast, cold and windy, provided the last opportunity to photograph some birds for another year. The intent was to set up a perch and photograph the little birds that frequent our area in the winter months. While setting things up, a Barred Owl flew in, perched in a nearby tree and immediately became the photographic focus for the next forty minutes until it flew off after being flushed by a White tailed Deer that passed under its perch.
Barred Owls are probably Ontario’s most common owl and are relatively easy to find. They are non-migratory and intact don’t move around very far from their place of birth. In fact in one study of more than 150 Barred Owls, none were found to have moved further than six miles over the course of the research.
It was quite windy on New Years Eve which adds an interesting perspective to this first portrait.
Barred Owls are easily identified by their large size, black eyes and lack of ear tufts.
Typical adults are similar in size and appearance, with an approximate length of 20″ and a wingspan approaching four feet. Barred Owls weigh about 35 ounces.
Owls rely on their feathers to insulate and protect their bodies and the detail and extent of the feathers is especially evident around the eyes and facial discs. This next image is included simply to show that even the eyelids are composed of layers of feathers.
The following tight profile view shows the amazing feather detail of the periorbital region of the Barred Owl as well as providing an interesting and almost artistic perspective.
The owl perched not twenty feet from where I was located requiring me to move away about the same distance in order to fit the full bird into the frame. Before moving back I was able to take the tight shots above, while the next two images are significant crops. (‘Crops’ are smaller portions of an original image that are created when processing images on the computer).
The beautiful and haunting dark-eyed stare of a Barred Owl.
Talons….the weapons of mouse destruction 🙂
Barred Owls eat a wide range of animals including fish, invertebrates, squirrels, rabbits, chipmunks and birds up to the size of a partridge. Their staples are voles and mice. Barred Owls hunt from a perch, intently staring and listening for the next meal opportunity to pass below. This last image shows a Barred Owl in a classic hunting pose.
Its hard to believe that another year has passed quickly by and I would like to thank you for taking the time to follow this blog. It is much appreciated as are your comments and questions.
The Moose is Algonquin Park’s largest animal (by both size and weight) and is certainly one of its primary and most recognizable icons. A trip to Algonquin Park is complete when you are privileged to see a moose, especially if it is a bull moose with an impressive array of antlers.
Deb and I have often seen moose over the years we’ve been visiting Algonquin Park but unfortunately the opportunity to photograph a bull moose with its majestic antlers had always eluded us. However this fall it was especially gratifying to see a bull moose after so many years of trying.
A while back my friends Arni,Eleanor, Joyce and I joined Michael Bertelsen (Algonquin Park Photography Tours) in the spring of the year where we saw a number of moose including bulls, cows and calves. You can read the account of this trip via this link (Moose In Algonquin Park). In the spring of the year moose are largely feeding on aquatic vegetation and the antlers on the bulls are covered with velvet which supplies blood for the rapidly growing antlers. Every fall the bull moose scrapes its antlers on trees causing the velvet to be torn off revealing the mature antlers beneath. This action causes the bull’s testosterone levels to rise and is part of the process that marks the onset of the mating season, or rut, which is typically between mid September and mid October. In the early winter months the bull moose sheds its antlers by breaking them off on a tree and soon thereafter starts work on growing next seasons bigger and better antlers.
Moose calves are born in early June each year and the cows have one or sometimes two calves. The calves stay with the cow for almost a year when mom forcibly releases her calf to fend for itself before she gives birth to her next calf.
Below is a cow with her two calves photographed in the park late this summer. We enjoyed watching this family graze in the marsh for at least thirty minutes before they wandered off into the forest.
I was happy to capture this next image with all three moose having mouths full of lily pads.
For their first year of life the little ones are never far from their mom.
Another cow with a single calf alongside Highway 60 that runs through Algonquin Park.
An inquisitive calf with mom watching closely in the back ground along the Mizzy Lake Trail.
Another young family near Lake of Two Rivers along the edge of the Madawaska River.
A portrait of the cow.
….and a young calf in the meadow.
These next two images are included to provide a profile of the cow and calf. The biggest difference between the two is found in the head shape.
Moose are the second largest animals in North America (the Bison is the largest) with shoulder heights ranging from 4.5 to 6.9′.
Over the past month I’ve visited Algonquin Park and been blessed to see and photograph a bull moose a number of times. This first image of a bull was taken a few years ago in June when the antlers are early in the growth stage and covered with velvet as mentioned earlier.
In the early fall the bull moose sheds its velvet and the antlers are revealed. Antlers are used for displaying to potential cows and challenging any bulls that may encroach on a cow that has shown interest in another bull. This next image shows the antlers of a fairly young bull moose, probably two years old based on the size and shape of the antlers.
This bull moose was photographed just after sunrise and the autumn leaves provided a great back drop.
I was surprised that this moose ambled slowly by and bedded down at the edge of a large meadow for about half an hour.
Adult bull moose weigh between 850 and 1,550 pounds while the cows are a little smaller ranging from 450 to 1,100 pounds.
After resting for about thirty minutes the young bull got up and continued in his morning grazing.
Moose are vegetarians and aptly named as ‘moose’ is a Native Algonquin word meaning ‘twig eater’. Their diet tends to be more aquatic in the spring and terrestrial in the fall and they typically eat leaves, bark, pine cones, twigs, buds of trees and lily pads. This next image shows the twig eater living up to its name!
In mid September it was 0°C before sunrise which created an extremely heavy fog around the lake where we were looking for moose. Walking along a trail we were excited to see three moose silhouettes just ahead of us, a calf, a cow and a bull all together, but the fog was so thick it was almost impossible to take a good picture. We watched them feeding for about 15 minutes and as the sun came up there was just enough light to get a couple of images .
This shot of the cow and calf was taken just after the sun had risen immediately behind the moose, creating a subtle back-lit glow.
This last image of a bull was taken about ten minutes before sunrise using an ISO of 4000 and aperture of f5 which was necessary to allow a shutter speed fast enough to prevent motion blur of the moose as it was walking toward the tree. You can see why photographers refer to the time before sunrise as the ‘blue hour’.
I trust you have enjoyed these photographs of our majestic Canadian gentle giants. Many more moose images may be seen via this link to the Wildlife Gallery.
Please feel free to share this blog with others and as always your questions and comments are very much appreciated.
Last summer Deb and I enjoyed a day on Bonaventure Island, four kilometres off the tip of the Gaspé Peninsula near the quaint little town of Percé, Quebec. The purpose of the trip to Bonaventure Island was to photograph the Northern Gannet, a large pelagic bird that for years has made Bonaventure Island the largest nesting site in the world for Gannets. With just over 52,000 nests (2012) among five colonies on the island, there are approximately 150,000 gannets on Bonaventure Island from mid-June to mid-September each year. This was actually the second summer that we travelled to Percé hoping to photograph the Gannets. On our first trip we were met with three days of high winds and heavy rains that created seas so rough that the boats could not leave the harbour for the short trip to Bonaventure Island. We were thankful to have perfect conditions on our second annual attempt!
The land masses of Bonaventure Island and Percé Rock were amalgamated in 1985 to become The Bonaventure Island and Percé Rock National Park. The island is also designated as a Migratory Bird Sanctuary. Access to Bonaventure Island is via ferry from the main dock in Percé, which is one of the most beautiful spots in Eastern Canada offering spectacular views of Percé Rock and Bonaventure Island. If you arrive early enough in the morning, you can purchase a $20 ticket to join the first ferry of the day which transports park staff to the island. It is a direct, 20 minute trip providing first access to the island and the 2km hike across the island to reach the Gannet colonies on the far side of the island. The regular ferry is $35 and takes an hour however you travel around Percé Rock and the far side of Bonaventure Island allowing you to see the Gannet colonies on the 300′ cliffs of the island. Deb and I were the only photographers on the staff ferry so the lead time allowed us to enjoy about 90 minutes alone at the Gannet colonies before the tourists and other photographers arrived.
Having the whole day set aside to spend on Bonaventure Island enabled us to plan for many different types of shots including some video. Although we probably took too much gear with us, we used it all and were thankful we made the effort to lug it across the island. Our gear for the day included a Kata backpack filled with a Canon 5D Mk III plus 16-35mm, 24-105mm and 100-400mm lenses as well as a Fuji X-E2 body, 8mm fisheye and 18-55mm lenses. Attached to the backpack was a Gitzo traveller tripod with Markins ball head. Balanced on my shoulder was a Canon 1Dx and 500mm telephoto lens attached to a Jobu carbon fibre monopod and gimbal head. It took about 45 minutes via the shortest trail to reach the Gannet colonies. It was a great hike on a well travelled path cutting directly across the island starting at sea level and rising to about 300′ over the 2km walk.
The hike is mostly in heavy forest and as we approached the far side of the island the scents and sounds of the Gannets greeted us long before the actual birds did. Both the smell and the sound were like nothing Deb & I had experienced before however we quickly acclimatized to both!
The Northern Gannet’s behaviour is quite paradoxical and some of these ironies will be highlighted throughout this post. I think this great pelagic bird is best summed up by Lucie Lagueux, a world renowned expert on the Gannet, who states “What surprises me most about the gannet is its overwhelming ambivalence. Although it is a sea bird, perfectly adapted to life in a marine environment, it spends more than six months on dry land. While its anatomy and behaviour make it eminently suited to cliff-nesting, it does not seem to be able to resist the temptation of the plateau. The gannet is a territorial bird, yet it lives in a very dense colony. It is an aggressive bird, yet its aggressiveness has but one goal: to ensure proximity to other gannets. Finally it is a very predictable bird – in most cases, the gannet’s reaction to a given situation can be easily anticipated. Yet sometimes it exhibits behaviour which is quite inexplicable”. This perfectly describes our observations of the Gannets during the time we spent with them.
When arriving at the colonies for the first time one is astounded by the sheer number of birds. It is difficult to appreciate what 100,000+ birds looks, sounds and smell like and although these images won’t do any of them justice, perhaps this video will help!
The density of the colony is shown below and its remarkable that Gannets returning from fishing excursions can find the exact location of their nest, however they always do. To put the density into perspective, the typical nesting site is 75 cm in diameter and adjacent nesting sites measure 80 cm centre to centre. Nest density is 2.3 nests per square metre.
Finding the right nest is a challenge for the Gannet and you can in this next image the reception that the landing Gannet receives from its neighbours.
The Northern Gannet is a large pelagic bird weighing on average 3.2 kg with a wing span of 1.8m. Gannets have average lifespans of twenty years however have been known to live for as long as forty. It is a beautiful bird, especially in breeding plumage when the head and crown take on a warm golden hue and the feet are accented with bold green lines.
Gannets are also beautiful in flight and their large wing span and thin wings make them excellent gliders. The white underside of the gannet also provides them great camouflage while hunting.
Nests are manicured mounds on the ground that are very sparse yet well defined as seen below. The highly territorial Gannet defends the nest fiercely even though they are very close to their neighbours.
The female Gannet easily lays a single egg as egg size is small compared to the size of the adult bird. Incubation lasts approximately 43 days during which the egg is surrounded by the webbed feet of the parent who’s increased blood flow to the feet keeps the egg warm.
Parents take turns between guarding their chick and fishing to provide food for the newest family member. They transfer partially digested fish to the young bird and it grows rapidly for the 75 days before it fledges.
Young birds remain on the nest until they fledge. As they expend little energy while confined to the nest and are continually being fed they actually grow to become larger and heavier than their parents. In fact they weigh almost 1 kg more than the adults when they leave the nest at 10-12 weeks of age. When they fledge they leave the nest and their parents for good and are on their own from that day until they mate at five years of age (younger birds will return to a colony at the age of two or three, but remain at the periphery of the colony and do not pair up or nest until age five). It is quite humorous to see a large young Gannet with its significantly smaller parents just before fledging.
New born Gannets can not be left unattended by its parents as neighbouring Gannets will attack them and should a young bird move off the nest it will surely be destroyed. This is one reason, the first year mortality rate of Gannets is over 60%. This next image shows the fate of a young bird that has inadvertently moved off its nest while its parent vainly tries to come to the rescue. You can see the remains of another chick in the foreground….a poignant visual display of life and death on a Gannet colony. When Gannets lose an egg or young chick they will often lay a second egg and have a second brood during the breeding season. For this reason you can concurrently observe chicks of all different sizes and stages of development within the colony.
Gannet behaviour is unique and fascinating to observe. The high density of birds in the colony make communication a survival necessity and the Gannets do so through tactile, visual and auditory channels. Gannet behavioural displays provide interesting photo opportunities for the bird photographer. I would highly recommend before travelling to Bonaventure Island that you take time to study Northern Gannets and familiarize yourself with their behaviour. This will allow you to better recognize what is unfolding in the colony and help you compose and capture the signature Gannet behaviours.
Fencing is perhaps the most easily recognized behaviour and is an important mating ritual. Gannet pairs extend their necks with beaks pointed skyward and delicately touch their bills together in a fencing motion. This activity always takes place at the nesting site. Fencing provides an excellent opportunity for that classic Gannet shot as shown in these next images.
To capture fencing effectively, a low angle is required to separate the Gannets from the other birds and also create a clear back ground to enhance the photographic result.
Yes, that means lying down in order to ‘get the shot’, but it’s always worth that extra effort!
You can see and sense the affection these birds share with each other, which as monogamous couples they do for life.
Although this next image lacks any eye contact (a bird photographer’s no no) it has become a favourite of mine with its artistic feel.
Mutual preening is another important mating ritual. The Gannet pair caresses and smooths the other’s feathers, typically around the head and neck.
They will preen each other for extended periods of time.
Unfortunately, fighting is common amongst Gannets, sometimes between pairs and more often with other Gannets that venture too close to a neighbouring nest. When fighting the birds anchor their claws into the ground and extend their necks to fight with their beaks. It often appears that they are attempting to jab the opponent’s eyes.
Threat-gaping, menacing and jabbing are related behaviours usually between Gannets on adjacent nests, where from a sitting position the birds jab towards each other while making lots of noise. There is generally no contact between the birds.
The last behaviour we will look at is called sky pointing and is thought to signal to a mate that the pointing partner is going to leave and the other is to stay and guard the nest. It is also performed by any Gannet in the colony who is about to take flight. When sky pointing, the neck is extended and bill pointed skyward, the wings are drawn back and the feet are prominently displayed with their bright green lines on black webbing.

The Gannets of Bonaventure Island feed primarily on Mackerel, Herring and Capelin and they consume lots of them. It is estimated that each bird consumes 500 g of fish daily and that the annual fish consumption of the Bonaventure colony is 3,100 tons or 6.2 million pounds. It is fascinating to watch Gannets fish as they always do so in groups. Look-out birds scout the ocean for schools of fish and once found they must signal the others as large groups of Gannets quickly congregate overhead and then with pin point accuracy dive into the school of fish from impressive heights and at great speed. This style of group diving, sometimes described as hailstorm fishing causes panic and disorientation within the school of fish and it is thought that this greatly improves the Gannet’s success rate compared to fishing alone.
The following images show the classic diving sequence of the Northern Gannet. These images were taken from the pier in the town of Percé which is where the ferries leave for Bonaventure Island. The waters between Percé and Bonaventure are sheltered and thus are a prime fishing location for the Gannets.
A Gannet cruising high above the water spots a target, puts the brakes on and prepares to begin its dive.
The dive begins with Bonaventure Island looming in the back ground
Gannets begin their dives approximately 100′ above the water and use their outstretched wings to steer them directly towards the target.
The wings remain fully extended until just before impact.
As they are about to enter the water they begin to quickly draw back their wings.
At the time of impact the wings are drawn fully back and neck is extended and the Gannet looks more like a torpedo that the very large pelagic bird it is.
The speed of the Gannet at impact with the water is 100 km/h and even at that speed, the large size and buoyancy of the bird only allows it to reach depths of five or six feet. They catch their prey while returning to the surface.
As we conclude this post I will leave you with some portraits and in flight images of the Northern Gannet. I trust these help give you an appreciation for this great bird of Bonaventure Island.
When given the opportunity, attempt to photograph birds against different back grounds which greatly influences the photographic results. The photo above has the sky as the background while the image below uses the water.
A unique pose with both eyes visible. Not a common occurrence in bird photography.
The long and slender wings of the Gannet make it ideally designed for gliding and riding the thermals that move up the cliffs on which they nest. This also allows the large and heavy Gannet to cover large distances with minimal effort.

Capturing two birds in flight in the same frame with both in focus is a difficult challenge but the perseverance required paid off….eventually!
They truly are a photogenic species.

Gannets normally dwell on cliffs but when there is no real estate left on the cliffs they occupy the plateaus atop the cliffs. They quickly denude the plateaus of vegetation and don’t often stray into grassy areas except to gather nesting material, or to offer the gift of grass to a potential partner, as an offer to build a nest together. It was a treat to find this Gannet with grass in its beak.
Apparently the object of his desire wasn’t overly interested in his kind offer!

Deb and I have had the opportunity to visit Percé and Bonaventure Island each of the past two summers to photograph Northern Gannets. We both highly recommend that you make the effort to travel to the Gaspé Peninsula of Quebec, not only to see the Gannets but to explore this very unique and beautiful part of our great country. You won’t be disappointed. If you want any Gaspé travel tips don’t hesitate to contact me as I’d be glad to help!
The Mountain Bluebird (MOBL) is a small sized thrush that prefers open space habitats in Western North American desert and mountainous regions. They are year around residents in the western states however migrate as far north as Alaska to breed and as far south as Central America during the winters. The male MOBL is a vibrant blue colour while the female has more subdued colours with strong blue wing colouration. The Mountain Bluebird is the state bird of Idaho and Nevada.
A few weeks ago a lone female Mountain Bluebird arrived in an open field on the western reaches of Lynde Shores Conservation Area in Whitby and quickly became a local celebrity amongst birders and bird photographers. For many it was their first time seeing one of these beautiful birds.
I was twice able to visit this bird and I’m thankful for one of those opportunities being with nice light for photography. The following are some of the images I was able to obtain of her. These photographs were taken last Friday morning, December 11th.
The object of an image is generally obvious and we always think about it before releasing the shutter however care must always be taken to consider the back ground of every image you take. Often the difference between a snapshot and a great photograph is the back ground. The first two images in this series have the black walls of a barn creating the back ground which creates a high contrast with bird. The great distance between the bird and the barn allowed the use an aperture of f/8 to keep all of the bird in focus and still blur the back ground enough that the barn was completely indistinguishable.
.
For the next two images I moved not more than ten feet in order to replace the barn as the back ground with a coniferous tree line in order to replace the black back ground with a green one. Although this is very subjective, I prefer the green which is a bit more natural looking and provides a better contrast with the beak of the bird. Compare images one and four and then two and three. Each pair is pretty much the same compositionally except for the back ground colour. Do you have a preference?
.
The remaining images are from a different perch which was located such that overgrown grasses provided the back grounds. The first three images are against a ‘white’ grass/hay back drop creating the brightest of the BG’s and great contrast with the bird….and it also complimented the rather ugly bamboo perch!
.
.
The final three images are against darker grasses that create a back ground shade which is perhaps my favourite of all we’ve looked at today with a nice warm tone that compliments the colours of the bird nicely.
.
When a rare bird makes an appearance hundreds of birders and photographers will make a point of seeing the celebrity. Typically that means a plethora of photographs will show up on various photo sharing websites and soon they begin to look quite similar. It’s wise to observe the bird and its various behavioural displays and look for that unusual shot. Sometimes even the very common act of preening will provide that unique image.
The Mountain Bluebird was last seen early Saturday morning when just after sunrise it was observed flying west, presumably to return to its home territory. Often these lone birds that get off track while migrating don’t survive the rigours and dangers of travelling long migration distances alone without the help and safety that comes with travelling in numbers. She certainly looked healthy when I took these pictures the day before she left so I trust that by now she has been re-united with her family.
All of these images were taken using a Canon 1Dx and 500/4 lens with 1.4 x TC for an effective focal length of 700mm.
