Birds

American Comb Duck

Native to South America, the American comb duck is one of the largest species of ducks in the world. These birds are named for the protruding, comb-shaped knob on the top of the male's bill. The comb itself is soft and is normally reduced until breeding season when it is enlarged to attract a mate.

The male American comb duck is much larger than the female. However, when laying eggs, several females may use the same nest called a "dump nest" that can contain up to 50 eggs. You can visit these ducks in the mixed-species crane and duck exhibit just inside Entry Village.

Blue-billed Curassow

The blue-billed curassow is the world’s most threatened species of the cracid family of crested game birds found primarily in Latin America. This curassow is the only example with distinctive blue bill ornaments, earning the species its common name. Very little is known about this bird in the wild due to its rarity; while at one time its range stretched 106,700 square kilometers, it’s now restricted to only a fragmented 2,090-square-kilometer forest area in northern Colombia. The blue-billed curassow has been severely harmed by losing nearly 99% of its habitat over the past decade due to agriculture and other habitat-destroying industries.

Nashville Zoo financially supports Blue-billed curassow conservation through the El Puajil Bird Reserve in Colombia.

Cassowary

Double-wattled cassowaries are solitary birds that live in some of the oldest rainforests in the world known as the “wet tropics.” They are the second largest birds in the world after the ostrich. They can be distinguished by their helmet-like casque atop their head and red wattles on their neck.

Cassowaries are important to the diversity of the rainforest. They consume over 78 different species of plants. Their poop helps to germinate new plants by spreading the seeds of the consumed plants. Female cassowaries will lay their eggs and leave the males to do all the incubating and raising of the chicks for up to 9 months. You can see our cassowaries across from Kangaroo Kickabout.

We participate in the Southern Cassowary Species Survival Plan®.

Flamingo

The flamingo is one of the most iconic birds of all time. Their diet contains carotenoid pigments which will give them their characteristic pink color. They have larged webbed feet to wade and stir up underwater environments to reveal food. Flamingos are filter feeders and hold their head upside down in shallow water to strain out their food. Flamingos very rarely lay down and even sleep standing up, often only on one leg. The Nashville Zoo is home to three species of flamingos: Chillean, Caribbean, and Greater flamingos. You can see our flamingos in Flamingo Lagoon.

Common Barn Owl

Barns owls are the most widespread of any owl species and can be found in any habitat that meets their needs. As with other owls they swallow their prey whole and then cough up pellets which contain all the non-digestible parts of their prey such as bones and fur.

Barn owls have great eyesight but they are renowned for their ability to hear extremely soft noises. A barn owl hunting in complete darkness can still locate and capture prey using sound alone. Barn owls have been known to nest in hollow trees and artificial nest boxes but earn their name by often taking up residence in old buildings such as abandoned barns and silos. You can see our barn owls at the Croft House barn.

Common Shelduck

The common shelduck is a species of waterfowl prominent in western Europe and Asia. Along with their goose-like appearance, shelducks are recognized by their loud “honking” call. Common shelducks are social birds and can be found in flocks of 50 to 100,000, in extreme cases. When breeding, common shelducks inhabit unused burrows, crevices and caves to nest and raise their young. Juveniles are born with the same unique pattern of white, black and green that is found on adults. If threatened by a predator, adult shelducks fly away from their young to act as a decoy, giving the ducklings a chance to hide by diving underwater. Our common shelducks share their habitat with the Stanley crane and white-faced whistling ducks.

Hyacinth Macaw

The population of hyacinth macaws in the wild has declined rapidly due to illegal pet trade and habitat loss. New initiatives to prevent illegal trading have been put in place, including the installation of artificial nest boxes and greater law enforcement.

Hyacinth macaws will use their powerful beaks with more than 300 pounds of pressure to break open palm nuts, their main food source. Females lay 2-3 eggs each breeding season with one chick usually making it to adulthood.

You can see our Hyacinth Macaws on exhibit just inside of Entry Village.

We participate in the Amazon Conservation Project, providing molted feathers to native tribes in South America. We also participate in the Hyacinth Macaw Species Survival Plan®.

Lorikeet

Lorikeets are very loud and social parrots. They roost at night in groups of up to thousands, and are very active in the mornings and evenings foraging in smaller groups. While other parrot species eat seeds and nuts, Lorikeets have evolved a long tongue that is covered in fine brush-like papillae that helps them gather pollen and nectar from flowers. Lorikeets can feed on thousands of species of plants, making them important pollinators in their native habitat. You can help feed our eight species of Lorikeets at Lorikeet Landing.

Mandarin Duck

Mandarin ducks are “perching” ducks which means that their legs are set far forward on their body and they are able to walk on land more easily and can often be found perching in trees. Male Mandarin Ducks are considered to be some of the most beautiful ducks. But the bright distinctive plumage of the males is lost during the summer months and it is difficult to tell males and females apart. The males will regain their bright feathers sometime in the fall. Mandarin Ducks have elaborate courtships displays and once paired will remain together for several seasons. They make their nests up to 30 feet high in hollow trees. Females will have 9-12 ducklings that will remain with the female for about 8 weeks. Only hours after hatching, the mother will leave the nest and call her ducklings. Although they can’t fly yet, the ducklings will launch themselves from the tree, and land harmlessly below. You can see our Mandarin Ducks in the pond at Lorikeet Landing.

Maleo

The maleo is a large bird native to islands in Indonesia with black plumage and a pink-peach underbelly. One of their unique traits is a crown on their head that is similar to that of a football helmet or acorn. Maleo’s are megapodes which translates to large foot. Maleos are mound-builders and when laying eggs, they use those long legs to dig out a nest in the sand. These eggs are about 5 times as large as chicken eggs and are covered up by sand in order to be incubated by the sun and geothermal heat. Once hatched, young maleos are completely independent and will begin their life alone. However, this species has become endangered due to the loss of nesting sites from egg poaching and land conversion. The Nashville Zoo is lucky to be one of the few institutions to have a maleo exhibit, so be sure to see our maleo in Critter Encounters.

Ostrich

The ostrich is the largest flightless bird in the world. They can run about 40 miles an hour covering 10-16 feet with a single stride. The ostrich will often use their wings as rudders to help change direction quickly while running. Ostriches will live in groups of about 12 birds. All the females of the group will place their eggs in the nest of the dominant female. A single ostrich egg is equivalent to 24 chicken eggs! Ostriches can often be found around other grazing animals like antelope and zebras. Ostriches have great eyesight and will often alert other animals of predators in the area. It is myth that ostriches hide their heads in the sand. They will put their necks close to the ground to try and hide from predators, from a distance it appears that their head is in the sand.

Rhinoceros Hornbill

The rhinoceros hornbill is one of 54 species of hornbill that exist. The rhinoceros hornbill can be distinguished by its banana-shaped casque on the top of its beak. It is thought that this is used to amplify the sound of its call. It is made out of keratin, just like our fingernails and hair and is very strong and lightweight.

Rhinoceros hornbills chose a nest high in a tree cavity. With The female inside a breeding pair works together to cover the opening with mud and scat, leaving only a small slit to pass food through. The female stays inside the nest for 3 months incubating and caring for the eggs. You can see our rhinoceros hornbill on Bamboo Trail.

We participate in the Rhinoceros Hornbill Species Survival Plan®.

Saddle-Billed Stork

Saddle-billed storks are the tallest of all storks. The pointed beak of the stork is used to repeatedly stab in open water or marshlands looking for prey. Recognized by the yellow skin, or lappet, that covers the front of the bill like a “saddle.” Saddle-billed storks mate for life and each pair will build their nest away from other birds and will defend their territory from other birds. Their nests are large enough to hide the bird completely while in the nest. Female saddle-billed storks will lay up to 5 eggs and both the male and female incubate the eggs and raise the chicks in the nest. Storks are a symbol of fertility and good luck. You can see our saddle-billed storks across from the meerkats.

We participate in the Saddle-Billed Stork Species Survival Plan®.

Southern Crested Screamer

Southern crested screamers are different from other waterfowl as they do not have webbed feet. They have long toes that help them grab onto vegetation as they walk through flooded areas. Their name comes from their unique call which can carry for several miles. Breeding pairs will protect their large nests where they lay 2-7 eggs. Young are capable of flying at 8-10 weeks. You can see our Southern Crested Screamers inside the Baird's Tapir exhibit.

We participate in the Southern Crested Screamer Species Survival Plan®.

Stanley Crane

Stanley cranes are migratory birds that live in large flocks. Pairs of Stanley cranes will conduct elaborate mating dances which include running in circles, calling to each other, and throwing grass. These birds are at risk in the wild from poisoning, habitat loss, and illegal capture. You can see our Stanley Cranes near Entry Village.

Tawny Frogmouth

The tawny frogmouth is a short, burly, carnivorous bird that is native to Australia. The name frogmouth comes from their wide olive-grey bill that is reminiscent of a frog. Many mistake these birds for owls with big yellow eyes and similar coloring. However, the tawny frogmouth is one of the best pest control birds as they use their bill to feed upon small prey during the night. They also have incredible camouflage and will mimic tree branches blowing in the wind during the day. You can see our tawny frogmouth inside Kangaroo Kickabout.

Toco Toucan

The toco toucan is one of the most recognizable tropical birds due to its incredible beak. The yellow-orange banana-shaped bill has a black base as well as a spot on the tip. The bill makes up about ⅓ of the total length of the toucan, and while it may look heavy it is relatively light. In fact, the inside is mostly hollow allowing for the toco toucan to regulate their body temperature by adjusting blood flow to the beak. You may even see them tuck their beak under their feathers to keep warm when they sleep. You can see our toco toucan inside Critter Encounters.

We participate in the toco toucan Species Survival Plan®.

Trumpeter Swan

The trumpeter swan is the largest and heaviest native waterfowl in North America. These birds are born with light grey plumage that turns entirely white after a year of life. Their entirely black bill and masks help differentiate them from other swans around North America. Their name, of course, derives from their call sounding close to that of a trumpet. Trumpeter swans will even choose a mate around the age of 2 to 4 and remain with them for the rest of their lives. These birds almost became extinct in the early 20th century, but due to conservation efforts, their numbers have been changing for the better. In fact, our zoo has our swans participating in a breeding program with the goal to release the chicks back into the wild! You can see our trumpeter swans in the pond outside of Unseen New World.

White-Faced Whistling Duck

The white-faced whistling duck is named for its bold pattern and unique call. Adult ducks have an easily distinguishable black and white head and communicate through high-pitched whistling noises. Unlike most waterfowl, the white-faced whistling duck is known as a tree duck, as it often perches on branches rather than remaining on the ground. Also unique to the white faced whistling duck is its tendency to remain monogamous for several breeding seasons. Because these ducks lack the colorful plumage other duck species use to attract a new mate each season, they invest more energy in keeping the mate they already have for several mating seasons. Our white-faced whistling ducks share their habitat with the Stanley crane and common shelducks.

Bird Species in the Aviary

There are currently 12 species of birds from Central and South America and Africa living in the Aviary inside Unseen New World:
