Red-footed booby

This seabird is the smallest of at least six species of boobies. It is about two and a half feet long and has a wingspan of five feet. Unlike the blue-footed booby which makes deep dives into water to catch fish, it often catches flying fish in the air, as well as making shallow dives. All boobies immediately swallow the fish they catch, unlike other fishing birds which may carry the fish in their beaks.

It has a similar range to the blue-footed booby and is commonly seen in Hawaii and the Galapagos Islands. Other species of boobies nest on the ground, but red-footed boobies live in colonies and nest in trees, where they lay a single blue egg.

Both adults incubate the egg for just over six weeks. The chicks learn to fly around three months of age, but it will be another eight weeks before they are able to attempt long flights.

The red-footed booby comes in several plumages, white, brown, or mixed, but all sport bright red feet and have blue bills. Some males also display blue throat patches when trying to attract mates.

They will not nest on islands where the Galapagos hawk is found, even if conditions are otherwise favourable. If the hawks have been eradicated from an island, red-footed boobies have been observed moving in to colonise it.

Humans continue to hunt and eat both adults and chicks, even though it is illegal. The birds bite the hands of humans attempting to take them from their nests. Two or three thousand birds are killed in most years.

Coconut crabs hunt red-footed boobies, using their strong claws to break the birds’ wings or trap them by their legs.

  5. Colourful birds I knew nothing about. So sad that people won't leave them alone; they seem to have enough natural enemies without humans adding to the dangers.

    1. We used to think the Dodo was a sad example of man's ignorance. Now there are so many more species going extinct.

  9. Thank you. 😺Seems that it's really tough to be a Red-footed Booby. Humans or crabs, someone's out to get you.

    1. It's surprising they're not in danger of extinction, really, since they only lay one egg. I was going to say they only lay one egg at a time, but don't know any birds that manage to lay two at the same time . . .

  12. All the boobies are such interesting birds. Well, I could say that (and probably have) about any species of bird, really.

  15. magnificent boobies! Thank you for this information . Of course humans would kill and eat them, humans are not as honorable as boobies.

  16. Never mind its red feet, the Red-footed booby's beak is something else indeed! xxx

  17. Red feet and blue beak. What a combination! A new bird for me.

  18. I didn't know about the red footed boobies. I knew about the blue footed ones though. I learned something today.

  19. These last two posts remind me of James Thurber's story, "The Unicorn in the Garden" ha. In case you're not familiar, the protagonist's wife calls him a booby and threatens to take him to the booby-hatch.

    All the best Jan

  23. These birds are getting more and more like a cute joke of nature feeling whimsical. I know, blue feet, red feet, what next, maybe striped? Spotted?

  24. Lovely birds, but I'm wondering how big the coconut crabs are to be killing these birds.

  25. I was fortunate to see both types of boobies when I visited the Galapagos Islands in 2014.

    1. Most attractive, but probably very smelly, like most sea birds.
