Strange-tailed Tyrant

Alectrurus risora

Striking flycatcher with a spectacular mating display, in which male flies high into the air and repeatedly pumps tails above and then below body. Endemic to the Iberá marshes of NE Argentina and E Paraguay. Male unmistakable. Female from other whitish flycatcher by orange throat, pale peach bill, and elongated tail. Prefers flooded grasslands with tall, undisturbed grasses, and is thus threatened by cattle grazing.

Little Bee-eater

Little Bee-eater

Merops pusillus

A small, mostly grass-green bee-eater with a canary-yellow throat separated from buff underparts by a black line across the throat. Singles and pairs occupy grassy savanna and wetland edges. They often perch lower than 1.5 m above the ground, and dart around hunting flying insects, then returning to the same small twig. Calls include a sibilant “s-lip” and other high-pitched notes. The Blue-breasted Bee-eater is slightly larger and has a white patch on the cheek. The much larger Cinnamon-chested Bee-eater has burnt orange underparts, and it prefers highland forest above 1800 m.

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. 

Slaty-legged Crake

Slaty-legged Crake

Rallina eurizonoides

Small, chickenlike dweller of dense forests and tangled edges. Dark brown above, with orange head and breast and black-and-white-striped sides. Juvenile similar but with brown head and breast, narrower white stripes below. Dark lead-gray legs distinguish this species from Red-legged, Band-bellied, and Ruddy-breasted crakes, which also show different underpart patterns. Sings at night from favored tree perches, a series of doubled hoots that recall Mountain Scops-Owl.
