I love urban wildlife and the way they have adapted to exploit the resources available to them in the environment, like human food waste. This week, pizza rat and milkshake squirrel highlighted rodents' ability to carry large food items, and digest a variety of foods.

Domestic cats put close relatives at risk

fiv The Scottish wildcat, closely related to the domestic cat, has been on the verge of extinction for a while now, due in part to urbanization, and hybridization with our own pet cats.

Possible solutions: vaccines, neutering pet cats, keeping pet cats indoors!

 

Wild cognition

Scientists in New Zealand  came up with a multi-task battery of cognitive tests to measure "general intelligence" in animals (these tasks included memory, motor skills, and symbol learning). They did these tests on wild robins, who were temporarily captured to participate in the study, and then released. Results suggested that some birds were "smarter" than others, and that the better they did on one task, the better they did on others!
