Red Footed Boobies are the smallest member of the booby family at only about 28 inches in length making them a couple inches smaller than the Blue-Footed and Nazca Boobies also found in the Galapagos Islands.
Telling the difference between these three types of boobies is quite easy as the appearance of all three is quite unique. The blue-footed booby is mainly white with brownish wings and bright blue feet while the Nazca (also known as Masked) booby is white with a black band around its eyes like a mask and pointed black wings. The red-footed booby has a range of color the majority seen in the Galapagos have a brownish body color with a blue and pink face, beak and throat pouch and red feet which give the bird its name.
During mating season hundreds of animals may pair up and mate. Unlike other boobies the red-footed booby build their nests in shrubs or trees. A female will lay an egg every 15 month. Both parents incubate the egg, and brood and feed the chick. The parents continue to feed the young for up to four months after fledging.
Red-footed boobies are excellent fliers and spend most of their long lives (up to 20 years) at sea. They are often seen flying above or along side passing boats. The red-footed booby is semi-nocturnal and can be seen fishing both during the day and for squid at night.
The colorful red-footed boobies are the least seen of the three species of boobies that are found in the Galapagos by visitors. The best way to see them is by taking a Galapagos Cruise that stops at one of their two nesting sites in the islands either at Genovesa or Punta Pitt on the northeastern tip of San Cristobal.

August begins the nesting season for Swallow-Tailed Gulls on the island of Genovesa. Though some pairs can be found along the coast in the region they are near endemic to the Galapagos Islands. When not mating these gulls are pelagic, spending their time hunting the waters near Peru, Ecuador and north to the coast of Colombia.
These medium sized gulls are the only fully nocturnal gull in the world. Their nocturnal feeding habits scientists hypothesize are for survival. Frigate, the pirates of the bird world feed during the day by stealing the chicks and prey of other sea birds. Swallow tailed gulls that leave their cliff shelters during the day can be seen being chased by the frigates. Additionally Red-billed Tropicbirds which feed during the day were direct competition for food. However the tropicbirds are able to plunge dive (unlike the swallow-tailed gulls) which allows the tropicbirds to feed on prey below the surface while the gulls can only prey on that close to the top. To survive the swallow tailed gull’s eyes adapted to allow them to hunt at night feeding on fish and squid miles from shore.
Swallow tailed gulls nest in colonies through the eastern side of the Galapagos. Their nesting patterns are synchronized within the colony. The couple will make a rudimentary nest or platform out of a piece of lava, coral, twigs or sea urchin spines. The nest protects the egg from rolling off the cliffs edge. Though most gulls lay three eggs per season the swallow tail gulls typically only lay a single egg. The egg is incubated for just over a month. After it hatches both parents take turns feeding the hatchling. Once the chick is 60 – 70 days old it begins to take flight. Its parents will continue to feed it for another month until it leaves to feed on the open seas.

The arrival to Genovesa is the most unique of any in the Galapagos. The island’s volcanic caldera long ago collapsed and as it filled with sea water it created what is now known as Great Darwin Bay. Arriving in Genovesa you are seemingly surrounded by the island on all sides as your boat lays anchor in the very belly of the island and its one time caldera.
Going ashore at Prince Philips Steps you climb a steep stair case to reach the island’s plateau. Here you will discover why Genovesa is known as “Bird Island” there is a vast potpourri of sea birds everywhere! Genovesa is home to the best collection of sea birds in Galapagos – there are frigatebirds, pelicans, herons, swallow-tailed gulls, tropicbirds, storm petrels, lava gulls and all three types of boobies – Nazca, blue-footed and red-footed.
There are smaller birds too like the Galapagos Mockingbird, Darwin Finch, Galapagos doves and short eared owls.
The wildlife of the island is not restricted just to birdlife. Snorkeling at Genovesa is quite exciting as well this is one of the best sites to snorkel with sea lions, fur seals and hammerhead sharks all on the same excursion.
For it’s fascinating collection of birds, great snorkeling and interesting entrance Genovesa is our choice for #2 top places to visit in the Galapagos.
