starts withThe glaucous-blue grosbeak is approximately 14 cm (5.5 in) long. Three birds weighed from 16 to 19.5 g (0.56 to 0.69 oz). The male is generally dark sky blue that is lighter on the forehead and rump and is grayish on the lower belly. It has a small black "mask". The female is brown overall, warm and dark above and orange-tinged below. The immature is orange-brown that is darker on the back, and it has a hint of blue on the forehead and cheek.
The glaucous-blue grosbeak nests in northeastern Argentina, southeastern Brazil, and much of Uruguay. During the austral winter, some move into southeastern Paraguay and further north in Brazil. It inhabits low, somewhat dense, vegetation such as along forest edges, on river islands, in marshes, and in secondary forest. In elevation it ranges from near sea level to 1,700 m (5,600 ft) in Brazil.
The glaucous-blue grosbeak is known to forage in pairs but other details and its diet have not been published.
The glaucous-blue grosbeak's breeding phenology has only been documented in Uruguay. There it nests from October to December. Two to four eggs are laid in a cup nest of twigs placed in dense vegetation.
