What is it about Blue-Footed Boobies?
Foot Fetish for Females of Blue-Footed Boobies
Do looks count? You can bet it does when it comes to the seabirds known as blue-footed boobies!
The color of their feet helps determine which male will be preferred over another when it comes to mating with a female. The female will always pick a male with the most colorful feet. Scientists have studied this and have determined this to be factual.
The more vivid colors in these webbed feet is a good indicator of the overall health of the birds. Just as humans often start losing color in their hair as they age with it turning to grey or white the blue footed boobies gradually start losing coloration in their feet. Thus the younger, heartier and healthier genes are passed on to the next generation by the females choosing the most vividly pigmented feet of their male suitors.
Unlike humans who sometimes mask their true hair color sadly for these birds there are no salons in the wild which can artificially tint a male blue-footed booby's feet back to its more saturated coloration.
Do male blue-footed bobbies flaunt this fact? Yes indeed!
Courtship of These Birds
They flip their feet up and down and dance in front of females showing off their pretty feet when they are in a courting mode. If they were human, blue-footed boobies would be like the famed dancer Fred Astaire all decked out wearing blue colored shoes!
They are interesting birds to be sure. Many of them are found in the Galapagos Islands and they range from the Gulf of California on down to Peru.

Favorite Fish is the Sardine
These seabirds can dive from great heights and they seek out schools of fish where they actually consume them while still underwater.
Their favorite fish to dine upon is the sardine. I don't blame them! Sardines can be a tasty food especially if acquired fresh.
If you have only ever eaten sardines in those little tinned cans, do yourself a favor and try to find some fresh ones to eat. My hubby and I got to eat sardines in Spain and remember it with gustatory pleasure.
The ones we tasted were lightly cooked and dressed with a light lemony vinaigrette and fresh herbs. They were delicious! I am sure that there are many different cooking methods that would be equally tasty.
Lightly grilling fresh sardines would be wonderful.
Our friendly birds need no special cooking methods to make them happy. Just scooping sardines up fresh right out of the ocean is all they require.
Sardines are often known to swim in schools so when locating them our colorful footed birds are undoubtedly sated in a short amount of time.
Egg Laying Habits of These Birds
One interesting thing about how these birds produce offspring is in their laying of eggs. A span of about five days can be the interval between egg laying for Blue-footed boobies.
The average number of eggs laid by blue-footed boobies are two.
Obviously the oldest egg hatches first in this type scenario. Typically since it is the biggest and strongest of the chicks it often gets the most of the regurgitated food from the parent birds.
Sometimes the older chick actually kills the younger ones. Talk about sibling rivalry! The younger chicks are very mismatched in this type of encounter.
The parent birds do not interfere in this rivalry between the chicks. In fact often the older chick is fed first by the parent bird.
Natural selection relating to Darwin's theory of evolution would seem to be more of random luck in this case.
That first egg and subsequent hatched chick most often wins the lottery with regard to survival long term. The others do not fare as well.

Quite a few birds lay their eggs not all at the same time from what I learned. However some (as in the case of the American Robin for example) do not start incubating the eggs until the entire clutch is laid.
Some birds start incubating after the first or second egg is laid thereby having the chicks hatching at different intervals such as is the case with blue-footed boobies.
