Until recently the Nazca Booby was considered a sub-species of the Masked Booby, but has recently been declared a separate species, endemic to the eastern tropical Pacific (mostly the Galapagos, where this was taken several weeks ago). I'll post a few more images of him in coming days. I thought of cropping this tighter to make it a pure head shot, but wanted to include a bit of the dark brown wing. Does this comp work? C&C appreciated.
