Phalcoboenus is a small genus of birds of prey in the Falconidae family. They are found in barren, open habitats in the Andes, Patagonia and the Falkland Islands. The four species are almost entirely allopatric. The adults are distinctive, with bare yellow, orange or red facial skin and cere, and a black plumage with variable amounts of white. Juveniles are overall brown with pale pinkish-grey facial skin and cere. They are highly opportunistic and typically seen walking on the ground, where they will feed on carrion and virtually any small animal they can catch
Physical charateristics
The adult bird is brownish black above; the upper-tail coverts are white, and there is a white bar on the end of the tail and on the wingtips. Below, including wing linings, it is white. The feathers on its forehead project upwards to form a slight crest, whilst those of crown are narrow and pointed. The sides of its head are partially bare of feathers. The eyes are hazel, the bill bluish, yellow near the tip; the cere and sides of head vary from yellow to orange; the feet are yellow. The immature is very similar, but its crown is less curly, and its colour generally darker.

Range
South America : South Chile, South Argentina. The Darwin’s or White-throated Caracara can be found on the slopes of the Andes from southern Mendoza, Argentina and Chile, south through Patagonia, and into Tierra del Fuego.
Habitat
This species is less well known than the Mountain Caracara (Phalcoboenus megalopterus), but many of their habits are similar. This species is common in beech forest, whereas the Mountain Caracara prefers open country. It is, at least in Chile, scarce and timid, seen in groups only at carcasses where they may gather along with Condors, Turkey Vultures and Common Caracaras.
Reproduction
Builds a stick nest on rock ledges. Clutch size 2-3 eggs,
Feeding habits
This species subsists on a mix of large insects and other invertebrates together with young rodents and birds. It is also not above scavenging for edible garbage and carrion.

Conservation
This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size may be small, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
If you hear a mourning-dove around your house, some one in the house will die unless you tie a knot into each corner of your apron. Then the mourning-dove will stop mourning and go away.
Dear visitor, we started two exciting new projects on PoB. Unique on the net we started posting Vintage plates and bird descriptions from the dawn of ornithology. Next to this we collected stories about birds in mythology, fables and folk lore. Many of these stories are founded in what is nowadays called ethno-ornithology. The next few months we will be publishing about 2000 new posts... The past months were quiet on the posting front, but frantic in research. Enjoy and help us by posting or commenting your own stories, fables or bird legends.

Buzzards never build a nest, because small birds say to them, "when the sun shines, what is the use of building a nest? Sun shine. When it rains, build when the rain stop." Dumb Buzzard never does build a nest.
