A study published in the journal Animal Behavior found that crows can recognize their fellow dead crows and learn to avoid the dangerous circumstances associated with death. The BBC described the study, which involved a "masked individual playing bad cop, arriving on the scene holding up a dead crow." [more inside]
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]
