|Chestnut-capped Blackbird (Chrysomus ruficapillus)
(aka Agelaius ruficapillus)
Brazilian name: Garibaldi
The Chestnut-capped Blackbird is found in eastern South America from French Guiana to northern Argentina and as far west as Mato Grosso and eastern Bolivia.
It breeds in lowland marshes and reed beds and is often found near rice fields.
|The male is unlikely to be confused with other blackbirds with its chestnut cap and throat although these can be difficult to see in poor light. The first photo is of the northern subspecies A. r. frontalis which has brighter chestnut markings than the more southerly nominate subspecies especially on the crown. All other photos are of the nominate sub-species.|
|The female, seen in the 4th photo, is a dull olive brown and could be confused with a female Shiny Cowbird Molothrus bonariensis except for its yellowish throat.
Photos 5 and 6 show an immature male where the male plumage is just beginning to show.
|There are illustrations in Ridgely & Tudor, Volume 1, Plate 21; and Jaramillo & Burke, Plate 20.
There are recordings and a distribution map on xeno-canto .
