Can abstinence make you more sexy?

If you are a blue-footed booby, the answer is yes. Female blue-footed boobies find males with bright-blue feet pretty sexy. The problem is repeated mating comes with diminished foot color and attractiveness as the males get older. What is a male with dull feet to do? Apparently the solution is easy. All they have to do is skip a breeding season and their feet become brighter again the following season.

What could contribute to the diminished color with breeding? Males boobies are actually attentive fathers and actively participate in raising their offspring. Therefore, researchers think this period of abstinence allows them to recover physically from the costs of reproduction. This is sort of nature’s way of telling them its time to take a break.

    Blue-balled blue-footed boobies.

    Someone had to say it.

  2. That’s hilarious! Tisk tisk you not-so-blue-footed boobies! LOL! Who would’ve thought that their feet would be so telling?

    Incredible! It’d be interesting to see if similar, visible tells/cues are present in other animals, or humans even.

    I hope more people can share in a blog or Facebook solve this problem.
