Everybody loves boobies. They are so darned cute. On the Galapagos Islands there are three species of boobies: Red-footed, Nazca (formerly masked), and blue-footed boobies. Foot color and intensity is an indication of health. Blue-footed boobies have an elaborate courtship dance that includes bowing and wing flapping and very sustained showing off of the feet. Look! My feet are bright blue! I am young and healthy! Pick me! Female boobies wave back with their feet if they like a guy. Lucky for us we saw a blue-footed booby couple dancing and calling. There was all kinds of foot waving and bowing.
Red-footed boobies are similar to blue-footed boobies that wave their feet and dance when looking for a sexual partner but the red-footed boobies also do a thing called sky-waving. They point their blue faces skyward and show off a blue throat. We did not see this but we did see nesting red-footed boobies and red-footed booby chicks. Red-footed boobies are very diverse in appearance. There is a white phase and a brown phase and several mixed phases between white and brown. Add to that juvenile versus adult coloration and sometime these boobies are hard to tell apart from other boobies.
Nazca boobies take a different approach. Nazca males find a tree based nesting spot and defends it. The ladies pick the males based on the desirability of the nesting site. Very sensible. Choosing real estate over theatrics and cosmetics is astute.
Boobies deep dive for fish. Their nostrils are permanently closed and a sac of air protects their brains from high impact dives. Each of these species fishes in a different area of the ocean. In close, out further, and out really far. Blue-footed fish close to shore and the red-footed fish scores of miles out at sea. The Nazca booby fishes in between.
Nazca is the name of a region of Peru and the tectonic plate of the Galapagos islands. Nazca boobies can be found in the Nazca region of Peru as well as teh Galapagos Islands.
