Essential Information on the Galapagos Frigatebirds
There are five species of frigatebirds scattered across the tropics, with two of them inhabiting the Galápagos Islands: the Great Frigatebird and the Magnificent Frigatebird. The distinctions between these two species are quite subtle, and only a trained naturalist guide is likely to help you identify them. The primary differences include the shoulder feathers, with the Great Frigatebird displaying a greenish sheen and the Magnificent Frigatebird showing a purple sheen. Additionally, the Magnificent Frigatebird is larger, with a wingspan of up to 45 inches (114 cm), compared to the Great Frigatebird's 40 inches (105 cm).
Frigatebirds are renowned for their impressive behavior during the breeding season. Males inflate a bright red sac on their throats to attract females and showcase their health and vigor. Competing males gather in groups with their wings spread, red sacs inflated, and heads tilted back. They clatter their bills, shake their heads and wings, and call out to passing females in hopes of catching their attention.
Primarily, frigatebirds are focused on foraging for food, which includes squid, fish, jellyfish, and crabs. They are also known to pilfer food from other birds, especially from Blue-Footed Boobies.
