Тонкоклювая пизарита Xenospingus concolor

Long-tailed, often rather skulking “finch” (actually a tanager) of scrub, hedges, and riverside thickets in desert lowlands, where no very similar species are found. Adult blue-gray overall with slender, bright yellow bill, and yellow legs; tail often held cocked. Immature looks very different: streaky overall with white eyering and slender yellow bill (darker on youngest birds). Voice notably varied: chips, clucks, and chatters usually given from cover.
