Male Frigatebird with Inflated Gular Pouch |
It was mating season for the Frigatebirds during my visit to the Galapagos islands in March. Male Frigatebirds are almost entirely black, except for a bright red pouch at their throats. Most of the time, it droops like a saggy sac. But when the males want to attract females, the males inflate their pouches to the point where it looks like they are big red balloons, ready to burst.

There was a huge concentration of Frigatebirds on Genovese Island -- known as Bird Island.
