Although located on the equator, the Humboldt Current brings cold water to the islands. However, the weather is periodically influenced by El Nino events, which occur about every 3-7 years and are characterized by warm sea temperatures, a rise in sea level, greater wave action and a depletion of nutrients in the water.
The Magnificent Frigatebird was probably my most interesting bird to see while in the Galapagos. They are large seabirds with long, angular wings.
Breeding males are entirely black except for a bright red throat patch which they inflate to attract a mate. It was amazing to watch this male inflate his throat patch trying to attract females flying overhead.
Females have a white chest and a dark head.
Juveniles start with a white head and gradually obtain darker heads.
