Brown Booby  1    One of the first birds seen on the foggy ocean side was a smallish sulid which showed continuous brown coloration on the upper parts and a brown looking chin throat upper chest and a clean demarcation to white (seen by one) or whitish underparts (seen by others).  The rump was the same color and we did see gannets today which in non adult plumage showed a pale/whitish rump and longer wing span.  The bird was in view for over a minute, but was hindered by foggy conditions which caused the bird to disappear as it flew away from us.
Independently several of us concluded it was a Brown Booby, likely the individual cruising around the western Atlantic with reports in Nova Scotia, Maine, New Hamphsire, and New York (via ebird).
There are reports from MA not in ebird; how many other reports from other states are not in ebird?
