Brown Booby Sula leucogaster, Dry Tortugas, Florida, May 15th 2005. ABA Code (3).



We saw good numbers of Brown Boobies during our two days on the Dry Tortugas, more so than we expected, and these birds were closest individuals we saw. From Garden Key, we observed a total of 17 Brown Boobies coming into roost on this marker on the evening of May 15th.

The images were taken using a Canon Powershot A-95 through Leica 10x42 binoculars as we passed the marker at about 30 m.p.h! Note the nice mix of pale-yellow billed adults and grayish billed immatures. Note also the pale eye of the immature on the right of the marker. Most field guides show Brown Booby having a dark eye at all ages.
