Don’t miss I and the Bird #45.  It’s gushing with winged wonder from around the blogosphere.

While I hate the premise of manipulating animal reproduction in order to create new breeds, I must admit the new “Toygers” cat breed is a real treat for the eyes.

Another strike against human uniqueness amongst animals: “Some animals are surprisingly sensitive to the plight of others. Chimpanzees, who cannot swim, have drowned in zoo moats trying to save others. Given the chance to get food by pulling a chain that would also deliver an electric shock to a companion, rhesus monkeys will starve themselves for several days. Biologists argue that these and other social behaviors are the precursors of human morality. They further believe that if morality grew out of behavioral rules shaped by evolution, it is for biologists, not philosophers or theologians, to say what these rules are.”

And while we’re on the subject of identifying so-called human behaviors in animals, let’s look at birds:

Emily DuVal, a biologist at the Max Planck Institute for Ornithology in Germany, found that male lance-tailed manakins display the behavior seen at nightclubs, where a person plays “wingman” or “wingwoman” to help a friend impress a potential mate.

In a study of 457 lance-tailed manakins in Panama, DuVal found repeated instances of two males performing a skilled dance for the benefit of a female bird who was watching. The group performance, however, helped only one of the birds — the alpha male. If only one lance-tailed manakin got to mate, why did the other bird, the beta male, cooperate in the dancing ritual when he had nothing to gain?

In a paper she published in the April issue of the American Naturalist, DuVal found there is evidence that good “wingbirds” are more likely than other birds to become alpha males themselves. What makes the behavior especially interesting is that one lance-tailed manakin might be helping another because some other bird will help the helper down the road. Such behavior suggests an intricate social system where investments pay off in the distant future.
