Pico de Plata
Hymenops perspicillatus
Length: 166mm. Sexes unlike. Male: bill, eyelids and iris yellowish cream; chin white; rest of plumage entirely black but for the primary and outermost secondary remiges, which are black to base and tip, remainder is white. Legs black.
Female: bill yellow at base and blackish brown at tip; iris light brown; eyelids very broad and yellow; supercilium yellowish ochre; upper part of head, hind neck and above mostly buffy brown with dark brown striation; rectrices dark brown. Throat whitish; breast, flanks, belly and undertail coverts cinnamon; the breast shows fine blackish brown striation.

Legs black.
Immature males are similar to females. Habitat and behaviour: found in marshes, ponds, and shrubby open country close to the water, reed beds, patches of cattails and bunchgrass. Usually found in pairs, perched in high branches or any exposed lookout, darting out to capture insects, looping back to the same perch. Males are more easily observed than females during their foraging flights, courtship or defence of territories. In flight it makes a very particular sound. The female, despite remaining close to the male, is often concealed. When moving to the ground to catch insects the Spectacled- Tyrant does so lithely. Nests are built hidden among tussocks of grass; a simple cup made of horsehair, plant fibres and feathers; clutch size is up to three white eggs with reddish and grey spots. Range: distributed from Neuquén and Río Negro to Chubut, where the race Hymenops perspicillatus perspicillatus is found; in the west of Río Negro and Chubut dwells the race Hymenops perspicillatus andina. Migrates northwards in winter.
