While the city shuts down due to the winter storm, Lincoln Park Zoo’s keepers and grounds crew braved the negative temperatures and gusty winds to head in to care for the animals and the zoo. While photos can’t quite do their dedication justice, here’s a roundup of what’s been happening at the zoo this week:…
Guira cuckoos have dark brown, white-striped wings; a long white-tipped tail; and spiky crest feathers. They bear some resemblance to the iconic roadrunner, another member of the cuckoo family. Highly social, these bird are often seen in flocks of six to 20 individuals. They prey on frogs, eggs, insects, and even small mammals, including chicks…
Hadada ibises are large birds with brownish-gray plumage that display an iridescent green sheen in sunlight. These birds hunt by dragging their long, curved bill in murky streams and grabbing any insect or small lizard they touch. Males provide nesting material, such as sticks and twigs, to females, who build their nest at the top…
Hamerkops have monochromatic brown plumage with hints of iridescent purple. These wading birds have a darkly colored, long, flat bill that is slightly hooked at the tip. They use their sturdy bill to catch fish, frogs, rodents, and other small animals.
Harbor seals can reach up to six feet in length, with males usually slightly larger than females. Specially adapted flippers help these aquatic mammals move quickly through the water while a thick coat of waterproof fur helps them stay warm. Harbor seals range from light gray to dark brown in color, and their fur is…

Hoffmann’s Two-toed Slothlpzoo.org/animal/hoffmanns-two-toed-sloth
Hoffmann’s two-toed sloths are solitary, largely nocturnal, arboreal animals. These sloths spend most of their time in trees, though they may travel across the ground to move to a new tree. Hoffman’s two-toed sloths are some of the world’s slowest mammals—so slow, in fact, that algae grows on their furry coat. The plant gives them…
Hooded mergansers are sexually dimorphic, meaning males and females differ in appearance. Females have a brown body, a white underside, and a light brown crest that extends from the back of their head. Males look similar during non-breeding season, except for their yellow plumage, but during breeding season, they turn black with white stripes near…

How Should Humans Treat Animals?lpzoo.org/how-should-humans-treat-animals
The principles of natural selection make clear the fact that animals have adapted to particular environments. We’ve all heard how giraffes evolved long necks to reach the highest branches or how zebras evolved monochromatic stripes to confuse predators. But these principles apply equally to behavior, as well. Animals have evolved patterns of behavior to suit…
Inca terns have a dark gray body and a red beak and legs. Moustache-like tufts of white feathers on each side of their beak signal maturity in males and females. They feed primarily on small fish, such as anchovies, and catch their prey by diving into the water with their pointed beak. Inca terns nest…
