|Brown-hooded Gull (Larus maculipennis)|
|The Brown-hooded Gull is distributed from central Chile to Tierra del Fuego and to south Brazil. During the austral winter there is some migration up the coasts of Chile and eastern Brazil. It is found along the coast as well as along rivers, lakes and marshes.|
|It looks very similar to Black-headed Gull Larus ridibundus and it has been treated as a sub-species of this in the past.
In breeding plumage it has a brown hood with white eye crescents. The bill and legs are deep red. The non-breeding adult has a white head with some dark spots behind the eye. The second photo shows a bird moving into breeding plumage. At this stage they can be confused with Grey-hooded Gull Larus cirrocephalus except in flight when the very different markings on the primaries are visible.
