The Hawk And The Vole

In my last post, Spring Has Sprung And The Birds Are Arriving On Cue I mentioned birding lately where there are no people so I can get out while practicing social distancing. These locations have proven to be incredibly rewarding in terms of birds and I have found the solitude to be incredibly beneficial for clearing my head and reducing stress.

IMG 9448 - The Hawk And The Vole — **A high perch provides a great vantage point of the meadow below.**

At one location in particular, I have had great views of a Red-tailed Hawk routinely seen soaring overhead or perched in a tree overlooking a large meadow. On my last visit as I made my way back to the car, I saw the hawk sitting up high in a tree and moved in for a better view.

IMG 9494 - The Hawk And The Vole — **After noticing something move in the field below the hawk took flight.**

One thing I always do when trying to get close to any type of wildlife is never walk directly towards it. I find by taking a zig-zag approach or going wide around the subject and advancing from the periphery I can get much closer. Also, I avoid direct eye contact rather keeping the subject in view out of the corner of my eye. In my opinion, approaching an animal straight on replicates a predator stalking its prey and the subject is almost guaranteed to flee.

IMG 9861 Edit 2 - The Hawk And The Vole — **At first, I couldn’t tell if the hawk had captured something of simply had a talon full of grass.**

As I got closer, I took several photos of the hawk perched against the clear blue sky. Sticking with the adage if my behavior changes their behaviour than I’m too close, I did not proceed as the bird remained calmly at rest in the tree. Watching the hawk, I could see something in the long grass caught its eye. With my camera still held near my face, the hawk took flight and swooped down to the ground about forty feet from where I was standing. As the bird hopped around on the ground I wasn’t sure if it had captured anything or not. After repositioning itself I could see the hawk had a vole in its talons.

IMG 9900 Edit - The Hawk And The Vole — **After repositioning itself I could see the hawk had captured a vole.**

I watched for several minutes as the hawk consumed the vole. First a few small bites then eventually swallowing what was left whole. Once finished the hawk took flight and retreated to a nearby tree. The whole experience lasted less than ten minutes and was a treat to see and photograph.

IMG 9924 Edit - The Hawk And The Vole — **The hawk’s sharp beak easily made short work of the vole.**

To capture these images I used my Canon 7D and Canon 100-400mm lens (both the old versions not the MkII) at 400mm. The images in this post are cropped only slightly to improve the composition. As far as camera settings go I was using aperture priority mode with my aperture set to f/8 and ISO at 800 resulting in a shutter speed of 1/1600.

IMG 9963 Edit - The Hawk And The Vole — **After tearing off several smaller pieces the hawk swallowed the vole.**

I hope everyone is getting an opportunity to get out and enjoy the warmer temps and spring weather we have been experiencing lately. The sunny skies sure are brightening our days both literally and metaphorically. If you get the chance, find a secluded place near you and spend a few minutes immersed in nature and sunshine. This is a great way to forget about what is going on in the world, relieve stress, and appreciate the little things that surround us each day.

Good birding,

Raptor Migration Getting Ready To Take Flight

As the days become shorter and summer slowly winds down, bird migration begins. Raptor migration is getting underway now and stretches right into December, with peak numbers being observed in mid September. One of the best places to view large quantities of migrating raptors is at Hawk Cliff in Port Stanley, Ontario. Hawk Cliff Hawkwatch begins September 1st and runs until November 30th. During this time, daily counts of each species of raptor are recorded. As part of Hawkwatch, there are two Hawk Cliff weekends in mid September with ground displays featuring live birds, information sessions, and hawk banding. For more on Hawk Cliff Hawkwatch, including directions to the cliff, click here.

Mid September is the best time to go if you wish to see the most hawks. September 16, 2013 saw over forty six thousand hawks counted, while on September 15, 2012 over twenty thousand hawks were counted. I was there on that day in 2012, and let me tell you, it was a sight to see. The sky was filled with hawks, falcons and eagles, as far as the eye could see. Some, like the Sharp-shinned Hawks and Northern Harriers pass by low overhead, while buteos like Broad-winged Hawks can be seen circling high overhead in large flocks, also known as kettles. Large kettles of Broad-winged Hawks can be made up of thousands of birds. It is these large kettles that lead to daily counts being so high.

9371729791 eabcd48a9b o - Raptor Migration Getting Ready To Take Flight — If the thought of crowds at Hawk Cliff may deter you, raptors can be found throughout the area. This American Kestrel, along with many others, was located west of town resting on a hydro pole.

Hawk Cliff is located at the end of Hawk Cliff Road overlooking Lake Erie. Parking is permitted at the sides of the road and this area gets quite busy especially during peak migration times. Carpooling is a good idea as I have heard complaints in the past about parking and accessibility at these times. Don’t let the crowds keep you from experiencing this incredible event. Crowds are much lighter during week days, so keep this in mind. You do not need to be right at the cliff to observe the migrating hawks. Great views of the birds are had along many of the county roads to the east and west of Port Stanley or from within the town itself. In fact, many species like Cooper’s Hawks, Sharp-shinned Hawks, and Northern Harriers pass by inland of the cliff itself.

Songbirds and butterflies also migrate through this area as they too follow the north shore of Lake Erie. Warblers, swallows, and vireos are among the many bird species that are observed. Before their decline, hundreds of Monarch Butterflies could be seen migrating through.

11240676706 4a518fb5fe o - Raptor Migration Getting Ready To Take Flight — On cloudy or foggy days, raptor migration is slower. Birds like this Cooper’s Hawk will wait in the area for more favourable flight conditions.

9675028020 d03cfa095c o 267x300 - Raptor Migration Getting Ready To Take Flight — Osprey prefer to migrate during a southwest wind. The wind hitting the bank at Hawk Cliff creates lift for them

Weather plays an important role in raptor migration. Wind, cloud cover and rain all factor in. Birds follow the shoreline looking for a the shortest distance to cross over. This typically occurs at the western basin of Lake Erie. Many hawks use northwest winds to push them towards the shoreline of the lake. They then lower their altitude to avoid being pushed out over the lake, making for excellent views. Falcons, Eagles, and Osprey tend to prefer a southwest wind as they use the lift created by the wind hitting the cliff to push them along. Migration slows on rainy, foggy days as most birds wait for more navigable conditions. If planning a trip, pay close attention to the weather. Look for a northwest wind following a couple days of rain to produce the best flight.

For me, no trip to Port Stanley is complete without a visit to the sewage lagoons. Located on the cliff west of town, great views of raptors can be seen soaring over the open fields. Two large observation towers overlook four lagoons, a great place to observe migrating shorebirds. Yellowlegs, sandpipers, and Great Egrets can all be seen. Many waterfowl species also stop over to rest and feed on the lagoons. As is the case near Hawk Cliff, Eastern Bluebirds are present in this area. Keeping an eye on the wire fences and power lines overhead often produces good views. To access the lagoons, turn west on Warren Street from Colborne Street (Highway 4). Go straight up the hill at the four way stop. Here it turns into Lake Line. From Lake Line turn right onto Scotch Line and follow the curve in the road. The first observation tower will be visible on your left.

If you are looking for a great place to do some late summer and fall birding, then check out the Port Stanley Lagoons and Hawk Cliff. Given the right weather conditions, you could be in for some of your highest day counts ever.

Looking for Raptors? Start With The Red-Tailed Hawk

If seeing a large raptor is on your birding wish list, look to the sky for the Red-tailed Hawk. They are equally at home in an urban or rural environment and can be found throughout a wide variety of habitat including forest edges, farmland, city parks, and even backyards. These large raptors are frequently seen perched on fence posts, hydro poles, or in large trees, and are the bird of prey that is most frequently seen when traveling along any highway.

Red tailed Hawk - Looking for Raptors? Start With The Red-Tailed Hawk — **The reddish orange highlights of an adult Red-tailed Hawk’s tail are visible from underneath when in flight.**

For the most part, Red-tailed Hawks are easily identified. Large stocky bodies, rounded wings, and a short wide tail are key features that assist in positive identification. Adult birds have dark brown backs and are streaked brown and white underneath. As the name suggests, adult Red-tailed Hawks display a reddish-orange tail most visible from the topside. In flight, the reddish highlights of the tail are visible from the underside. Juveniles, as with many raptors, are a little tougher to identify. Their tails lack the reddish colour and are dark brown with narrow darker bars. Sometimes a view of the tail is not always available. If this is the case, juveniles are also distinguished from adult birds by their eye colour. A yellow iris indicates a young bird. As the birds mature, the iris becomes a reddish-brown.

IMG 7018 1 - Looking for Raptors? Start With The Red-Tailed Hawk — **The brown tail with dark narrow bars combined with the yellow iris of its eye, identify this as a juvenile Red-tailed Hawk.**

Small mammals including rabbits, squirrels, mice, and voles make up the majority of the Red-tailed Hawks diet, but they will also consume birds and reptiles. Their diet varies depending on range and season. In my travels, I have personally seen Red-tailed Hawks eating squirrels, rabbits, starlings, and frogs. Their varied diet and habitat are things that lead to their wide range and abundance.

IMG 7022 1 - Looking for Raptors? Start With The Red-Tailed Hawk — **The loud screech of this juvenile Red-tailed Hawk quickly gave away it’s location.**

The loud screeching call of this raptor is most often heard during courtship and when juveniles leave the nest. If you hear this call look up, as this large hawk is most likely overhead. On one of my recent walks through a city park, I came across a group of young hawks that had recently fledged. Their sharp calls quickly gave away their location and their short flights were a joy to watch and photograph.

10380144924 2b2773292a o - Looking for Raptors? Start With The Red-Tailed Hawk — **The red tail for which this hawk is named is most visible from the topside.**

Keep an eye to the sky and treeline next time you are out for a walk or traveling down your local highway. Chances are you will see one of these beautiful raptors.

Spring Marks The Return Of Osprey To London Ontario

The Osprey is a large member of the raptor family that feeds almost entirely on fish. They can be found around any body of water from lakes and reservoirs to rivers and ponds. Since the ban of DDT their numbers have increased and can be readily found in the London area once they return in early spring from their wintering grounds, which stretches from the southern United States to Central and South America. Ospreys are tolerant of human activity and several pairs nest within the city limits in parks, Environmentally Significant Areas and along the Thames River.

Ospreys construct their nests of sticks and line them with bark and grasses. The nest is placed in an open area where an easy approach can be made. Look for Osprey nests in tree tops, crotches between tree branches or manmade structures such as telephone poles and lights posts. Ospreys usually mate for life and will reuse the same nest from year to year adding material to it each year. Nests can be as large as 13 feet deep and 6 feet across. Clutch sizes are 1-4 eggs with incubation lasting 5 weeks. Both adults take care of the brood and fledging takes place after 8-10 weeks.

As with most raptors Ospreys have incredible vision and can spot fish underwater from heights of over 100 feet. Once a fish is spotted the Osprey briefly hovers overhead before diving feet first into the water. The Osprey is specially adapted for a fish diet with closable nostrils to keep water out, reversible outer toes and backwards facing scales on their talons to help hold onto fish.

9675028020 d03cfa095c o1 - Spring Marks The Return Of Osprey To London Ontario — The Osprey is the only large raptor with a solid white belly. This is a key to identification and helps distinguish them from a juvenile Bald Eagle and other birds of prey.

Most years Ospreys start to reappear in the London area in early April. Given the cold winter and increased amount of ice across their migration route it may be later this year, unless we experience a significant warm up. Keep an eye out along river banks and shorelines of lakes and ponds once the ice is off. Ospreys are sometimes confused with Bald Eagles but there are several things to look for when identifying them. Mature Bald Eagles are larger and much stockier than the rather slender Osprey and have a solid white head and tail. The body of a mature eagle is solid brown, with the Osprey being a mix of brown and white. Ospreys are the only large raptor with a solid white unmarked belly. Juvenile Bald Eagles are mottled on their undersides and lack a white head.

Keep an eye to the sky and in tree limbs overhanging bodies of water in your favourite birding area. If you see a large brown and white raptor there is a good chance you’ve just spotted an Osprey.

Bald Eagles

Bald Eagles Call London Home

Bald Eagles have always impressed me. Their massive bodies, thick beaks, and incredible wingspans are a real sight to see. Luckily I don’t have to travel very far to do so. More and more Bald Eagles are calling London and area home. With several nest sites in our area and many birds overwintering here, Eagle sightings are becoming more frequent. Eagles nest in forested areas in close proximity to water as their main food source is fish. Look for them near lakes, rivers or reservoirs. Eagles like to perch in the tallest trees with a wide view of their surroundings so when looking for them make sure you are looking high in the trees. These birds are huge and their white heads and tails make identification easy. In flight look for their wings to be held straight and not in a V which will at a distance distinguish the Bald Eagle from a Turkey Vulture.

I have the most success finding Eagles during the fall and winter months once all the leaves have fallen from the trees. Spotting the birds in a leafless tree is quite easy due to their size. Many Eagles can be found up and down the Thames River from Delaware to Fanshawe Lake. The river’s current keeps it from freezing so it provides an excellent source of food for the Eagles. Fresh fish is not the only food that Eagles consume. They will also eat birds, small mammals, and are excellent scavengers so not all meals are live caught. In winter months look for Eagles outside the city in fields on the ground feeding on various carcasses.

The sight of a Bald Eagle is truly remarkable. If you have never seen one you will be amazed at the sheer size of this raptor. I have seen and photographed these birds numerous times and still get excited whenever I come across one. My biggest challenge is holding the camera steady as I tend to shake a bit due to the excitement. If adding the Bald Eagle to your life list is something you are having trouble with, try walking the banks of the Thames River before you go booking your Alaska vacation.
