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).

coopers hawk male and female

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.

Thanks 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).

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: 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.
