Dendroica petechia petechia. I got a brief glance at this bird at the Graeme Hall Nature Sanctuary in Barbados, West Indies. This is a 35-acre oasis within the historic Graeme Hall Swamp watershed and is regarded as one of the last significant wildlife habitats on Barbados. The sanctuary was saved from almost certain development as a golf course by conservation philanthropist Mr. Peter Allard, a retired attorney from Canada. This is a very quiet and beautiful reserve. Just on the other side of the very busy and narrow coastal highway is a proliferation of restaurants and beach hotels along the very beautiful ocean.... f/5.6, iso 1600, 1/200 This incredible complex species posseses at least 43 currently recognised subspecies, with almost certainly more on Venezuelan offshore islands awaiting description. It is usual to separate them into three groups (Browning 1994), which are sometimes considered separate species (eg R&G, Hilty). It is virtually impossible to separate three groups in the field satisfactorily and only males can be identified with any certainty. Familiarity with songs is helpful. 1) Northern Yellow Warbler, aestiva group - male has yellow head (migrant from North America and northern Central America) 2) Golden Warbler, petechia group - male has chestnut crown (resident in West Indies and N coast of Venezuela) 3) Mangrove Warbler, erithachorides group - larger than aestiva group, shorter, more rounded wings, smaller bills and males chestnut head (resident in coastal Central Am. and northern South America) Birds of Northern South America (Restall)
