tjocknäbbad tangara Sicalis taczanowskii

Drab and nomadic finch-like bird found in desert and arid scrub in northwestern Peru and southwestern Ecuador. While some birds show a distinct yellowish wash on their face and throat and a short mustache, many individuals lack these features, and easily could be confused with female Parrot-billed Seedeater. Sulphur-throated Finch has a more striped back and a differently shaped bill, with a more curving top edge and a longer and straighter bottom edge. In the dry season, this species may congregate in flocks of hundreds of birds that fly around in tight, swirling formations.
