White-faced Ibis

Plegadis chihi

Long decurved bill. Dark overall with iridescent green and reddish tones on adults. Broad white border to reddish face and red eyes. Found mainly in shallow wetlands of the western U.S. Best distinguished from Glossy Ibis by range and facial pattern. Also note more subtle features: reddish legs and paler bronzy tones to wings.

Identification

The white-faced ibis is very similar to the glossy ibis in its non-breeding plumages, but it tends to be slightly smaller and the plumage color is somewhat warmer. Breeding adults have a pink, bare face bordered with white feathers (rather than a bluish bare face with no bordering feathers), a grey bill, and brighter-colored, redder legs. Adults have red eyes year-round, whereas glossy ibises have dark eyes. Juveniles of the two species are nearly identical.<p>Measurements:

Range and habitat

The white-faced ibis occurs in Canada, the United States, and Central America, and a second subspecies inhabits the southern half of South America, east of the Andes Mountains. In 2012, the total population size was estimated to be 1.2 million individuals, and increasing. The IUCN rates it as being of Least Concern.<p>Migration and interchange between North and South American subspecies does not occur. Within North America, birds breeding in northern areas of the range move south to wintering areas. For example, breeders in northern California and southern Oregon move to wintering areas in southern California and México or Central America. Some birds breeding in Yellowstone in Wyoming will overwinter in areas such as Texas and coastal Gulf of Mexico regions.

Pacific Reef-Heron

Pacific Reef-Heron

Egretta sacra

A small heron that hugs rocky coastlines. Light-morph individuals are usually white all over, though some may show patches of gray. Dark-morph individuals are entirely dark gray. Both morphs have a yellowish green bill and legs. Light morph adults are distinguished from egrets in the area by their distinct short-legged appearance and noticeably thicker bill.

Henst's Goshawk

Henst's Goshawk

Astur henstii

A big, powerful goshawk. Adults are gray on the back with fine gray barring below; females much larger. Immatures have a brown back and thick streaks below. Endemic to Madagascar, where it is a scarce resident of all types of primary forest. Rarely sits in the open, and only occasionally soars. Territorial call is a loud repeated “khew” which is often given in flight. Males can be very hard to separate from similarly-sized female Madagascar Sparrowhawk. On Henst’s, look for fine bars on the undertail, a completely barred throat, and a central toe of normal length. Immatures may only be separable based on toe length. Also very similar to the rare Madagascar Serpent-Eagle. Subtle differences include slightly smaller size, evenly-spaced barring on the chest, thicker black bands on the tail, and an unbarred back. 

Brown-backed Woodpecker

Brown-backed Woodpecker

Dendropicos obsoletus

A small, short-tailed woodpecker with a brown back. Note the white facial streaks that frame a dark cheek. Males have a red back of the cap and females a completely dark cap. Found in a variety of open habitats, including savanna, woodland, scrub, and forest edge. Most similar to Cardinal Woodpecker, but separated by the dark cheek and the plain brown back. Vocalizations include a series of several wailing notes and a quiet rattling.
