Raptors of the world: Black-Hawk Eagle

Spizaetus tyrannus.

A medium size bird of prey of the Americas. Found in tropical forested regions in Southern Mexico, and south throughout Central America all the way to Peru, Bolivia, and Brazil. They hunt a variety of prey usually from a perch. They take prey as large as toucans, small monkey, and iguanas. Bats, squirrels, snakes, and possum are also on the menu.  Nests are made high in the treetops, and made of branches, vines, and sticks.

This was a fun panel to paint. Making such a dark colored bird stand out on the panel was an enjoyable challenge. Thanks 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).

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.

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.

Raptors of the World: Harris’s Hawk

Parabuteo unicinctus.

Found in semi-open desert regions. Often among mesquite, saguaro, and organ pipe cactus. This fascinating raptor is one of the few social predators in the animal kingdom. They hunt in groups, from two to six for rabbits, squirrels, and birds. Utilizing strategic methods of flushing and ambushing prey. They also work as a group to defend large carrion from coyotes and other predators.

Not only do they hunt in groups, but they also nest in groups. As many as three adults feeding one nest. Nests are built high in mesquite trees, on man made structures or cliff sides. Laying 1-5 eggs per clutch.

Birds of the World: Emperor Penguin

Aptenodytes forsteri.

The tallest and heaviest of all penguin species. A fascinating social bird endemic to Antarctica. They feed primarily on fish and sometimes crustaceans and squid. They swim to catch fish and can stay submerged as long as 18 minutes. Several adaptations allow this, including unique blood, and a control of its metabolism allowing it to conserve energy in low oxygen situations.

They are the only bird known to breed during the Antarctic winter. Traveling in groups to breeding territories. Females lay one egg which is incubated by the male. The average lifespan is 20 years though researchers have found some as old as 50. In large nesting sites mates communicate with complex and unique vocalizations.

Thanks again for looking at birds with me.

Owls of the World: Fulvous Owl

Fulvous Owl (Strix fulvescens) known also as Guatemala Barred Owl. Is found from Southern Mexico to Honduras. They prefer high-altitude tropical and temperate forests. Until recently it was just considered another race of Barred Owl (Strix varia). It’s coloration and song both resemble their Northern cousins. They’re quite elusive and proper study has still yet to be conducted to delve further. Fulvous Owls feed on small mammals, birds, reptiles, amphibians and insects. They lay 2-5 eggs per clutch and nest in holes in trees.

Thanks for looking at birds with me.

Owls of the World: Ural Owl

Strix uralensis

The Ural Owl is found across Northern Europe and Northern Asia. And as far east as Japan. Preferring remote old growth forest. They hunt primarily voles but substitute with other small mammals, insects, and birds when vole populations are low. Hunting from perches relying on their incredible hearing, silent wings, and razor sharp talons.

Ural Owls lay up to six eggs per clutch. Nesting in dead trees or even an abandoned Goshawk nest. They are very defensive of their nests, chasing away anything that approaches the entrance. Unless it’s a returning Goshawk in which case they would be in trouble.

Hawks of the World: Crested Goshawk

 

 

Accipiter trivirgatus

The Crested Goshawk is found in Southeast Asia. Their short, broad wings and long tails are adaptations for maneuvering through trees to pursue prey. They feed on birds, small mammals, and reptiles. The females are larger than the males and lay 2-3 eggs at a time.
