The greyish saltator (Saltator coerulescens) is a passerine bird in the tanager family Thraupidae that is widespread in the tropical Americas. 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!"

Taxonomy[edit]

The greyish saltator was formally described in 1817 by the French ornithologist Louis Jean Pierre Vieillot under the binomial name Saltator coerulescens.[2] Vieillot based his description on the "Habia de la Ceja Blanca" that Félix de Azara had described in 1802 in his book on birds in Paraguay and the Río de la Plata.[3][4] The specific epithet coerulescens is derived from Latin and means "blueish".[5]

There are 13 recognised subspecies.[6]

Description[edit]

Juvenile in Venezuela

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.[7]

Distribution and habitat[edit]

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.[8]

Behaviour and ecology[edit]

The greyish saltator feeds on fruits,[9] 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.[7]

Egg

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.[10] They are laid in a bulky cup nest 2–4 m high in a tree.
