This is a common bird on both coasts and can be seen all months
of the year. However, there are few breeding colonies. There
is an old report of a breeding colony on Bird Island, which
is a Honduran island in the Gulf of Fonseca, though Monroe did
not find any breeding when there when he visited. Monroe also
mentions a colony on Little Swan Island, which is a Honduran
Island in the Caribbean. On my pelagic trip off El Salvador
on 2nd July, we saw 199 birds, but, surprisingly, we did not
see any on my pelagic trip off the coast of Guatemala on 11th
May. During the El Salvador pelagic, we saw large numbers of
birds resting on a shrimp boat about 40 miles from the coast.
Great Frigatebird Fregata minor should also be looked out for
in the waters off the Pacific coast of northern Central America.
They breed on Islas Revillagigedo to the north and the Galapagos
Islands to the south and have recently been recorded off Costa
Rica. This species is more pelagic than Magnificent frigatebird,
so could easily travel such long distances.
