Return of Bird of the Week: Plumbeous Rail

“Plumbeous” means “lead-like,” and while the Plumbeous Rail’s body is dark grey, the bill and legs more than make up for the drab body. It’s not the best quality photo, but it’s a high-quality bird. It’s a widely distributed Rail, ranging from southern Ecuador to Tierra del Fuego. It’s also one of the easier rails to see; most are skulky and a few, like North America’s Black Rail, are near-impossible. WC saw them at sea level and in marshes at 10,000 feet. A pretty amazing distribution. For more bird photos please visit Frozen Feather Images.  

Return of Bird of the Week: Austral Pygmy-Owl

Austral Pygmy-Owl, Tierra del Fuego National Park, Argentina

WC found it completely by accident. Birding with Marcelo de Cruz in Tierra del Fuego National Park, Marcelo was imitating a pygmy-owl call, a birding technique to make songbirds move where they can be seen. To our surprise, he got an answer. After considerable searching in the soggy thickets of Tierra del Fuego, we found it. You’ll have to look closely. The bird is pretty cryptic, which is important to a daytime ambush hunter. The species is tiny, a male like this is just a bit over six inches long and weighs about two ounces. This is the southern limit of…

Return of Bird of the Week: Snowy Sheathbill

Snowy Sheathbill Portrait, South Georgia Island, Southern Ocean

There are no vultures in the Antarctic. But there is carrion. The ecological niche of carrion eaters is occupied instead by the Sheathbills. Sheathbills are odd in a number of ways. Two species of Sheathbill, the Snowy and the Black-faced, make up the entre family of Chionidae. They are also the only land bird in Antarctica, meaning they have talons and not webbed feet. They are the only sub-Antarctic species with bare skin on their face, and the only species with those odd, horny plates on their will. It’s those plates that give the bird its common name. Like a…

Return of Bird of the Week: Kelp Goose

Male (L) and Female (R) Kelp Goose, Tierra del Fuego National Park, Argentina

This is a strange goose, endemic to Patagonia and the Falkland Islands. It’s sexually dimorphic: the male is bright white with very large yellow legs; the female is dark brown with a heavily barred neck and chest, and a white eye ring. Kelp Geese are found exclusively on coasts and islets, generally on rocky or pebbly shores. It feeds only on the algae and seaweed growing on the rocks. This is probably the Hybridia subspecies. The species is poorly known to ornithologists. Even the population is a guess: 15,000. The species is not believed to be endangered. For more bird images, please…

Return of Bird of the Week: Chimango Caracara

Chimango Caracara, Tierra del Fuego National Park, Argentina

There don’t seem to be any corvids – the family of birds that includes crows and ravens – in far southern South America. Their ecological niche in North America is filled by falcons, and especially by the Chimango Caracara. An adult bird is about 18 inches long. It’s behavior, at least for the birds WC saw, was strikingly like a Common Raven: bold, habituated to people and opportunistic. For example, it hangs around campgrounds and has been known to steal unattended food. Despite being one of the most common diurnal raptors in southern South America, there hasn’t been a lot…

Return of Bird of the Week: Southern Lapwing

Southern Lapwing, coastal Peru

Lapwings are a species of Plover. They are widespread across South and Central America, and there is considerable variation among the four subspecies. This is a bird that has succeeded and prospered in the face of human alteration of their ranges. This is a grassland bird, and man’s creation of pastures and fields has simply given the species more range. It’s not a bird you could easily confuse with any other. The face, very odd head shape and bright red eye and extensive black on the face, neck and belly are unique. The species has a crest in both sexes,…

Return of Bird of the Week: Dolphin Gull

Dolphin Gull, Tierra del Fuego National Park, Argentina

(This week’s Bird of the Week is late; WC was off the internet for a while.) Another species from southern Argentina, Chile and the Falkland Islands, the Dolphin Gull is a smaller member of the Larids, the gull family. With its bright orange-red bill and legs, and yellow eye, it is possibly the easiest gull there is to identify in the field. It’s a scavenger and opportunistic predator. This bird is cruising a mixed colony of Rockhopper Penguins, Black-browed Albatross and King Shags, looking for an unguarded egg of chick. But its smaller size make it a target for bigger…

Return of Bird of the Week: Austral Parakeet

Austral Parakeets, Tierra del Fuego, Argentina

Another species of Tierra del Fuego, the southernmost large island in South America, is the Austral Parakeet. It’s a cousin the late, lamented Carolina Parakeet, North America’s only native member of the parrot family. The species’ range extends up the coast of Chile. In Tierra del Fuego, it’s a sea level bird, but further north it ranges to 2,000 meters. The Austral Parakeet is suffering population declines as a result of deforestation, competition with non-native species, and human captures for pet trade. But overall, this is a species of least concern. While WC saw only this one pair, the species…

Return of Bird of the Week: Black-faced Ibis

Black-faced Ibis, Tierra del Fuego National Park, South America

Tierra del Fuego is the largest island at southernmost tip of South America. Like most island ecologies, it has been heavily impacted by humans, but many of the native birds still occur. One of them is the Black-faced Ibis. The black-faced ibis is mainly found in southern South America, ranging throughout most of southern and central Argentina and Chile. It’s certainly colorful. While the Peruvian population is likely extirpated, it’s still pretty common elsewhere in it historic range. Ornithologists get cranky when you ask about this species. It’s not well-studied, there’s a lot of disagreement about subspecies and classification with its…

Return of Bird of the Week: Southern Giant Petrel

Nesting Southern Giant Petrel, South Georgia Island, Southern Ocean

A warning: this one is a little gruesome, and there are photos that some may find offensive. You’ve been warned. This is  Southern Giant Petrel, by any measure a big bird. More than three feet long and with a wingspan of nearly seven feet, this 11 pound bird is another top-tier predator in the Southern Ocean. Note the naricorns, the tube-like structure on top of the bill. It’s part of the mechanism these birds use to expel excess salt. They don’t need fresh water; they can live on salt water. The bird’s suspicious stare is for a Brown Skua considering raiding…
