One of my favorite professors in college was an ornithologist, and one of the few reasons I would willingly get up early on the weekend was to go birding with him. He led our class on a trip to Ecuador and the Galápagos islands, where we saw pelicans, oystercatchers, herons, frigatebirds, and three different kinds of boobies, as well as Darwin’s famous finches. Here’s one of my favorite shots of a male great frigatebird in flight.
We use the mnemonic “green is great” to distinguish the great frigatebird, which has greenish feathers, from the magnificent frigatebird, which is more purple-ish. Females have white patches at their throat instead of the males’ red throat pouch.
You can find more taking flight at the original Lens-Artist challenge.
