|White-browed Blackbird Leistes superciliaris
(aka Sturnella superciliaris)
The two striking features of the White-browed Blackbird are the prominent white stripe behind the eye and the red breast. The second photo shows that this red is also visible on the wings in flight.
|The female, seen in the 4th photo, is quite different being brownish with dark streaks and a buffy supercilium. There is a pinkish hue to the breast.
In fresh plumage, the male has pale brown edging to its feathers, as can be seen in the 5th photo. These gradually wear to show the more intense black of the breeding bird.
|They are found in grasslands and pastures and, given the agricultural development in South America, they are increasing and expanding their range which is in north-east Brazil and central Brazil with Bolivia, Paraguay, Uruguay and northern Argentina.|
