Buteo Hawks of North America

 

This slideshow requires JavaScript.

Here’s five of the more common Buteo hawks found in Canada, Mexico, and The United States. All feed primarily on small mammals such as: Rabbits, voles, mice, squirrels, and prairie dogs. Insects, birds, and reptiles are also on their menu. All are frequently found in open areas. Grasslands, desert, and sparsely forested areas. Many have adapted to human habitation impacts and can be found hunting from a perch upon a utility pole along an urban roadside.

For more information about these birds definitely check out www.allaboutbirds.org

It’s one of my favorite online resources for raptors and other birds of North America.

I’d like to credit Floyd Scholz’s book “Birds of Prey” (Stackpole Books 1993.) as an indispensable resource in raptor illustration.

These illustrations are done in Micron pen and watercolor.

Thanks so much for looking at birds with me.

Hawks of the World: Cooper’s Hawk

Accipiter cooperii.

We’ve looked at this one here before. I featured the male Cooper’s hawk on this very panel in the spring of 2015. I’ve learned a lot about painting and this species since then. I felt it was time to sand that painting off and start anew. This time featuring the female Cooper’s hawk. I’ve included a few pen and watercolor illustrations to help further illustrate the differences between the male and female plumage as well as one to help differentiate from the Sharp-shinned hawk (Accipiter striatus).

Females Cooper’s hawks are larger than males and can take larger prey. Males tend to only take small birds, while the females can take birds as well as small mammals like squirrels and rabbits. Nests are made in treetops and laying 3-5 eggs per clutch. eggs are a cobalt blue color.

Cooper’s hawks can be found throughout North America. Preferring woodland habitat where they chase down prey through the treetops. They’re also found in urban environments. Preying on birds and squirrels that frequent bird feeders.

It can be easy to confuse Cooper’s hawks with Sharp-shinned hawks (Accipiter striatus). Especially given the size differences between male and female Cooper’s hawks. A male Cooper’s hawk can be the size of a female Sharp-shinned hawk. The tail feathers of the two are the best indicator of who’s who. Here’s an illustration I put together to explain the differences.

Hawks of the World: Japanese Sparrow-Hawk

Accipiter gularis, or Japanese Sparrow-hawk is a medium size accipiter. Like many Accipiters, females of this species are larger than males.  These fast flying hunters can be found in coniferous and deciduous forests of Eastern Asia. Breeding in China, Japan, Korea, and Siberia. Winters in Indonesia and Philippines.

Accipiter gularis feeds on birds as large as magpie, also takes bats, rodents, and reptiles. Nests are made close to tree trunks and made of sticks and leaves. Laying 2-5 eggs per clutch.

Hawks of the World: Jackal Buzzard

Buteo rufofuscus

One of the more interesting colored hawks of Africa. Found in the mountainous and open regions of Southern Africa. Prey includes small mammals like mice, moles, and hyrax. Though reptiles and birds also make up a healthy portion of their menu, and occasionally carrion. The Jackal Buzzard is similar in size to the Red-tailed Hawks (Buteo jamaicensis) of North America. Not surprising as they’re related.

Nests are constructed by both the male and female. Utilizing branches, leaves, and grass. The preferred nest spots are high in treetops and on cliff sides.

I have made a couple of pen and watercolor illustrations of this bird, it was fun to make a life size panel painting. Thanks a bunch for looking at birds with me.

Raptors of the World: Ornate Hawk-Eagle

Central and South America are home to an interesting variety of birds of prey.  The Ornate Hawk-Eagle is definitely no exception. If its name hadn’t already made that clear.

Found in humid tropical forests from southern Mexico and south as far as Argentina. While rare in its range it’s listed as near threatened in its IUCN Conservation Status.

A powerful bird, like other booted eagle species they are capable of taking prey up to five times their own body weight. Feeding on birds such as toucans, little blue heron, parrots, chickens, and wood quail. Mammals also make up a large portion of their diets, such as Agoutis, squirrels, rats, and monkeys. Snakes, lizards, and other reptiles round out the menu.

Nests are made high in treetops, and comprised of large sticks. Usually only laying one egg at a time in breeding season (April-June).

Hawks of the World: African Goshawk

African Goshawk

Accipiter tachiro

This medium sized accipiter can be found gliding over its densely forested habitat. They primarily still hunt for their variety of prey that includes: reptiles, insects, mice, birds, and bats.

They nest in dense foliage building nests of sticks but also known for taking over nests of other birds.

This was a fun 11×14 panel to work on. I’m currently working on a larger 18×24 panel of a large South American raptor. Thanks for looking at birds with me.

Falcons of the World: New Zealand Falcon

Falco novaeseelandiae

A powerful falcon endemic to New Zealand. They vary slightly in size, birds found in grasslands are larger than those found in forested areas. Also like many falcons females are larger than males.

They hunt birds and small mammals from a perch or from circular flight paths. Dropping on unsuspecting prey from above. Hitting prey with outstretched talons then severing the spinal column with a bite to the back of the head with their serrated bill. An effective hunter to say the least.

Aggressive hunters and defenders of their nests. Reports of falcons attacking humans who ventured too close to nesting areas are common. Much like goshawks in the northeast United States.

Nests are made in a variety of places. From on the ground in bushes all the way up high on cliffs or ledges from 20 to 100 feet. 2-4 eggs are laid at a time from September to December.

And if you’re keeping score at home, we’ve already looked at this bird about a year and a half ago. I wanted to go back and make some revisions. Having researched the bird more there were too many inaccuracies and I always love a chance to paint another unique falcon like Falco novaeseelandiae again. Thanks again for looking at birds with me.

Hawks of the World: Red Shouldered Hawk

Buteo lineatus.

Definitely one of my favorite birds to watch and paint. Found across eastern North America and along the California coast south into Mexico. Hunting from a perch and on the wing. They take a variety of prey, ranging from small mammals, birds, insects, snakes and occasionally fish.  Found in forested and open areas. Nests are built of branches in treetops at 35-50 feet up. They lay usually 3 eggs per clutch.

Thanks a bunch for looking at birds with me. We covered this bird already here something like three years ago and I felt it was time to have another go at painting this bird as I’ve learned a lot since the last time. I’m glad I did, this was very fun to put together.

Raptors of the World: African Harrier-Hawk

African Harrier-Hawk or African Gymnogene. These large birds of prey are found in most regions south of the Sahara. They Feed on oil palm fruits, and uses its long double jointed legs to reach into dead trees and crevices to steal eggs or snatch at small mammals, reptiles, and insects. Also hunts from a perch or even walking on the ground. They build stick nests and lay 1-3 eggs per clutch.

Raptors of the World: Harpy Eagle

I wanted to paint this bird to scale but didn’t have any panels large enough so I settled for a portrait on a 16×20″.  With talons as long as a grizzly bears claws and a wingspan of over 5 feet. The Harpy Eagle is an apex predator and can be found hunting in the treetops of tropical and subtropical forests. From southern Mexico south to Brazil and Argentina. Their diet consists largely of various sloth species and monkey species, including capuchin, howler, spider, and squirrel monkeys.

If you’re not in South America and you want to see these birds in action then check out “The Hunt” on Netflix. Another great nature doc narrated by Sir David Attenborough. Season 1 episode 3 has a great segment on Harpy Eagles. The whole show is awesome and in the same episode is a great segment on Cooper’s Hawks.

I just picked up some great books on African birds of prey and I’m excited to get lost in them. I’ll find us some good birds. Thanks again for looking at birds with me.
