What's the deep history of birdiness?

Scientists say they have reversed a bit of bird evolution in the lab and re-created a dinosaurlike snout in developing chickens.

The scrub jays of Santa Cruz Island really love a good peanut.

This Jay Is Evolving in a Very, Very Weird Way. As she gathered more and more data on different populations of the island scrub jays around Santa Cruz Island, Katie Langin, a biologist at Colorado State University, had a revelation: The birds, members of one single species, had split into two varieties in different habitats. Ever since Darwin and his famous finches, biologists have thought that in order for a species to diverge into two new species, the two populations had to be physically isolated. Those finches, for instance, each live on a different Galapagos island, where their special circumstances have resulted in specialized bill shapes. Yet the two varieties of island scrub jay (they haven’t technically speciated—yet) live on the same tiny island. If they wanted to meet each other for a brunch of acorns and/or pine nuts and perhaps later some mating, they could just fly right over. [more inside]

" It is my goal to have the most complete collection of gaping animal maws that anyone can have"

Gaping Maws is a collection of photos of animals with their mouths wide open. Like this.
