Pohnpei White-eye

A medium-sized pallid and delicately-patterned sandgrouse. Pale and sandy overall. Note male’s silver-gray eyebrow and orange cheek and throat. Female has a paler version of the male’s pattern, as well as a speckled nape and chest. Lacks breast bands, unlike Pin-tailed and Black-bellied Sandgrouse. Very similar to Crowned Sandgrouse, but note the present species’ tail filaments and different facial pattern. Note the strong contrast in two-toned underwings when in flight. Flight call is a characteristic “Waka! Waka!” Favors sandy or stony desert plains where it breeds on the ground. Congregates to drink in waterholes in the morning, often flying back and forth over long distances in large flocks.

Chunky, large-billed, streak-backed cisticola. Brown overall, without bright rufous in the plumage. Males are much larger than females. Found in grassland and savanna with scattered bushes. Song varies geographically but always consists of a rising note with a croaking quality. Larger than Stout Cisticola and lacks a bright rufous crown. Distinguished from most other cisticolas by large size and heavy bill. As with all cisticolas, habitat and voice are important cues in identification.

Small-billed cinclodes of the Sierra de Comenchingones in central Argentina. Disperses to adjacent lowlands during the nonbreeding season. The only Cinclodes in range with extensive rufous on wings; yellow base to mandible also distinctive.
