Tawny Frogmouth

These nocturnal birds have cryptic, drab-colored plumage and they roost themselves vertically in a tree with their bills to the sky during the day, giving them the ability to camouflage to look like a broken branch!

In order to protect and defend their chicks, a male tawny frogmouth will ruffle up his plumage, as well as hiss and snap his impressive bill at a potential predator.

Unlike owls, tawny frogmouths have short, weak legs and feet, so they hunt prey by scanning the ground from low perches in their territory. Once located, they glide down and pounce on it, snapping it up in their powerful bills, and return to the same perch to eat it. They have a wingspan of 18-24 inches.

Domestic Chicken

About: Domestic chickens vary greatly in appearance due to breed, though they share common traits: squat stature, rounded bodies, dense feathers, and wattles of flesh around the face. Adult roosters (males) have distinct combs of red flesh and striking plumage including flowing tails and shiny, pointed feathers. Roosters may also have spurs on their legs, which they employ in battles with other males. With some breeds, a “beard” of feathers is prominent under the chicken’s face. There are ‘bantam’ breeds, a smaller variety of chicken, and some breeds have tail feathers that span several feet long!

Life Cycle/ Social Structure Chickens have very sophisticated social behavior with a dominance hierarchy where higher individuals dominate subordinate individuals. This is where the term “pecking order” comes from! The dominant male protects the females (hens) and they choose to feed close to him for safety. Roosters are generous when it comes to food-the males may call to their hens when he finds food, prompting them to eat first. This behavior is also seen with hens and their chicks.

Bald Eagle

About: The adult bald eagle has a white head and tail with a dark brown body and wings. They have an 8 foot wingspread. Their bills are bright yellow with a sharp hook. Legs are also bright yellow with powerful black talons and rough scales for holding on to fish. Young birds have a brown head until attaining adult coloring at about five years of age!

The bald eagle population drastically declined from the late 1800’s to the late 1900’s. Many were killed for sport, but the biggest impact may have come from powerful pesticides used in the farming industry. These pesticides caused high chick mortality, and the eagle population plummeted, earning it a spot of the USA Endangered Species List. Due to the regulation of pesticides and the protection afforded by the ESA, the bald eagle has reached stable numbers and was delisted from the ESA in 2007.

All bald eagles are under the supervision of the USFWS. The zoo’s resident eagle came to the zoo after he was rehabbed for being hit by a car, and can no longer fly. The zoo collects all naturally fallen feathers and sends them to the USFWS!

Predators: Adult eagles are at the apex of the food chain and have no natural predators. Nestlings and eggs are at risk from gulls, crows, hawks, owls, other eagles, bobcats, black bears, and raccoons.

Life Cycle/ Social Structure Bald eagles mate for life and reinforce their pair bond through spectacular flight displays that involve midair courtship dances. In winter, bald eagles sometimes collect in large groups close to fish-packed bodies of water. Bald eagles become territorial during breeding season and may aggressively defend nesting sites by grappling in midair. Their territories vary greatly by geographic location and home ranges appear to overlap. Suitable roosting sites are usually large trees near water and ideal sites are selected for their height, diameter and protection from inclement weather and predators. Timing of reproductive activity differs by climate and latitude, but usually occurs between October and May. Nest sites are returned to and expanded each year. Nests may grow as long as 9 feet wide and 15 feet deep!

How you can help: One way to help eagles and other birds is to recycle paper! Trees are needed for all wildlife to thrive, and eagles need large old trees to build sturdy nests! You can help us bring birds of prey back from the brink by supporting the Lehigh Valley Zoo.

Domestic Turkey

Habitat/Range: Domestic turkeys are raised throughout the temperate parts of the world. Their wild counterparts prefer hardwood and mixed conifer-hardwood forest with varied clearings such as pastures, fields, orchards and marshes. Turkeys are native to North America and were taken to Europe by the Spanish in the 1500’s.

Life Cycle/ Social Structure

Males are polygamous and mate with as many hens as are available. Male turkeys display for females by puffing out their feathers, spreading out their tails and dragging their wings, known as strutting. Males may be seen courting in groups, with the dominant male strutting and gobbling.
