The Greyish Saltator, "Saltator coerulescens", is a seed-eating songbird that is widespread in the tropical Americas. Traditionally placed in the cardinal family (Cardinalidae), the saltators actually seem to be closer to the tanagers (Thraupidae)See the genus article for details] . In El Salvador, it is well-known as "dichosofui" after the "elaborate" version of its call, which sounds like a drawn-out "¡dichoso fui!", Spanish for "I was happy!"

Description and systematics

On average, the Greyish Saltator is 20 cm long and weighs 52 g. The plumage depends on age and subspecies, but in general this bird has grey or greyish-olive upperparts, a white stripe over the eye, a narrow white throat, a grey breast and a buff or cinnamon belly.

The common call is a long-drawn upward slur, "ch'wheeet" or "ch'kweeee", sometimes with a more elaborate beginning, as "hi'whee chu weeeeh". The song is a warble, usually fairly short, varying from nasal to mellow.Howell & Webb (1995)]

The genus "Saltator" is apparently polyphyletic. Whether the present species will remain in "Saltator" or eventually be moved to another genus remains to be seen; it appears to be rather close to the type species, the Buff-throated Saltator, and thus seems more likely than not to retain its genus name.

There are 13 subspecies, several of which are considered full species by some authors, mainly on the basis of vocalisations. [Peterson (1999)]

Distribution and ecology

This species occurs in open woodland, plains and scrub, from Mexico through Central America into southern South America, south to Peru and the Paraná River region in northern Argentina [BLI (2004), Bencke (2007)] . The Greyish Saltator feeds on fruits [E.g. of "Trophis racemosa" (Moraceae): Forster (2007).] , buds and slow-moving arthropods. It forages at low and middle levels, sometimes in pairs or small groups and sometimes with mixed-species flocks that may include other saltators.

The two pale blue subelliptic eggs per clutch measure some 23–31.5 mm long by about 17–22 mm wide and weigh about 5 grams each. They look unusual for this genus as they have a circle of blackish-brown hairstreaks and dots around the blunt end [Echeverry-Galvis & Córdoba-Córdoba (2006)] . They are laid in a bulky cup nest 2–4 m high in a tree.
