These birds are unique in that the females look different than the males, showcasing the beauty of dimorphism. But that’s not all – their prominent bills and gorgeous plumage make them a sight to behold.

White-headed Ducks are also impressive divers! They engage in extensive feeding at night, feasting on mideg larvae, and can remain underwater feeding for up to a minute before resurfacing! 

The Masked Bobwhite is a member of the New World quail family. A subspecies of the Northern Bobwhite, the Masked Bobwhite is distinguished primarily by the male’s striking appearance—it has a mostly un-patterned black head and throat and rich cinnamon-colored underparts.  Female Masked Bobwhites are very similar to females of the other subspecies.  Masked Bobwhites have a very restricted range including only a few locations in extreme southern Arizona and central Sonora, Mexico.  These populations were historically very vulnerable to overgrazing, habitat fragmentation, and drought. Today, only about 200 Masked Bobwhites live in the wild, but an active captive breeding and release program is helping Masked Bobwhites raised in human care to begin to repopulate their scrubby grassland habitat.  Masked Bobwhites have a very short nesting season because they will breed only when humidity is high, and this occurs naturally only in association with the seasonal monsoon rains.

The Scaly-sided Merganser is a diving duck that breeds in Siberia, northern China, and Korea, and winters in southern China and in Russia. This species makes its home along clear, fast-flowing mountain rivers and forested streams in the taiga, a swampy coniferous forest between the tundra and the steppes. Scaly-sided Merganser females sometimes end up caring for two or even three times the number of their chicks through a process called “brood amalgamation,” where other females’ chicks get absorbed into a different brood. The species is endangered, and is harmed by logging, dam construction, gold mining, and recreational water use.

The Mariana Fruit-Dove is a beautiful bird from the Pacific islands. This species is found in various types of forested habitat, but prefers mature native forest where it typically feeds on fruits in the canopy, but may descend to feed in bushes, or even on the ground. They are a secretive species, rarely spotted, and nearly always solitary. The Mariana Fruit-dove has been extirpated (locally no longer present) from Guam and is threatened on Saipan by the introduced brown tree-snake.

In 2020, the National Aviary welcomed its first ever Mariana Fruit-Dove fledgling! The hatching of this beautiful little chick is an important step for securing a brighter future for Mariana Fruit-Doves.

Like the Golden White-eye, the Saipan White-eye, also known as the Bridled White-eye, is a small, understory specialist. Restricted to the island of Saipan in the Northern Mariana Islands, this species occurs in a wide variety of wooded and semi-wooded habitats, including native limestone forest, scrubby secondary growth of disturbed habitats, and even urban areas. The Saipan White-eye consumes a generalized diet of insects, including caterpillars, ants, and grasshoppers, as well as small snails, seeds, fruits, small berries, and nectar. Although still locally common, the introduction of the brown tree snake on Saipan has put this bird at extreme risk.

The National Aviary is a partner with the Marianas Avifauna Conservation (MAC) Project, which is working to save this and other species in the region from extinction. Although the population of this species still numbers in the hundreds of thousands, the introduction of the brown tree snake on Saipan puts this bird at extreme risk; consequently, it is considered endangered by the International Union for the Conservation of Nature (IUCN).

The Red Siskin is an Endangered species owing to its popularity as a cage bird. The Red Siskin is a vibrantly colored finch that was once plentiful in Venezuela and so recognizable that their image is printed on Venezuelan banknotes, written into poetry, and appears in works of art. Native to the northern regions of Venezuela and Columbia, the Red Siskin inhabits dry deciduous woodland in the lowlands and foothills, as well as scrub or grasslands with scattered trees, and the edges of evergreen forests. Siskins are mostly granivorous, foraging on the seeds of various grasses, forbs, and trees, but they will also consume fruit and berries. Although legally protected, the cage bird trade continues to impact this species. Throughout the 20^th century the birds were trapped and exported as part of the illegal wildlife trade, and were highly prized for their coloring and were bred with canaries. Their numbers dwindled almost to the point of extinction. Now Endangered, fewer than 7,000 Red Siskins remain in the wild in small, isolated populations.

A small, understory specialist, the Golden White-eye is an Endangered bird restricted to the islands of Saipan and Aguijan in the Northern Mariana Islands. This species occurs in a wide variety of wooded and semi-wooded habitats, including suburban areas where it pursues a generalized diet of berries, seeds, nectar, and flower parts, as well as flying insects and other small invertebrates. Although still locally common, the introduction of the brown tree snake on Saipan has put this bird at extreme risk. The National Aviary is a partner with the Marianas Avifauna Conservation (MAC) Project, which is working to save this and other species in the region from extinction.

The Yellow-naped Amazon is an Endangered species of the Pacific coast of Mexico and Central America. It inhabits semi-arid woodland, arid scrubland and pine savannas, and treefall gaps in tropical deciduous and swamp forests. Often found in large and noisy flocks, they feed on a variety of seeds and fruits. They nest in hollows of trees. The Yellow-naped Amazon suffers from extensive poaching of nestlings for the pet trade, perhaps more than any other Amazona parrot, and its population is in steep decline.

African Grey Parrots, a medium-sized parrot native to the forests of central Africa, are some of the best mimics in the bird world. In the wild, this species often copies the sounds of other animals in the forest. Around people, they may learn to copy a variety of sounds including laughter, a phone ringing, whistling, human speech, and many other sounds. Two African Grey Parrots roosting in Zaire were reported by researchers to have a repertoire of over 200 different sounds, including nine imitations of other wild bird songs and even one of a bat! This species is widely believed the be one of the most intelligent bird species. African Greys can live to be 60 years old. While their charismatic personalities and mimicry make them popular, they can be very challenging to keep as pets. This species is vulnerable to the illegal wildlife trade and habitat loss and destruction.

Native to East Africa, the Gray Crowned-Crane is featured on Uganda’s coat of arms and flag and is the country’s national bird; this bird also is a sacred symbol for Kenya, Namibia, Zambia and South Africa. The Gray Crowned-Crane is unique among the cranes in being one of only two species capable of perching in trees, owing to their having a long hind toe useful for grasping. Although this species has historically favored wetlands and open grassland or savannah, it is now found mostly in human-modified habitats, such as pastures, croplands, and ranches. Here the Gray Crowned-Crane feeds on seeds of sedges, fresh tips of grasses, crickets, locusts, and other insects and small animals. To hunt for food, the Gray Crowned-Crane stamps its feet on the ground to cause bugs to run out of the grass. This crane nests in or along the edges of their wetland homes, but young birds do not fledge for almost 100 days. The Gray Crowned-Crane has suffered a massive decline in population resulting from a plethora of impacts of human population growth and expansion of agriculture resulting in loss of wetlands, sedimentation, and contamination.
