Those clever nuthatches

When I posted Peter Barss’s photos of tool-using nuthatches, it struck me as remarkable that two different species were using the same tool in the same location on the same day. I wondered if there could be some teaching and learning at work here, but figured I was getting getting over my head, animal behaviour-wise. Contrarian reader Bill Matheson had the same thought:

You may also have evidence here, even if anecdotal, to suggest cross-species cultural transmission of tool use. The red-breasted nuthatch seems to be gifted at learning from other species, according to the Nuthatch article on Wikipedia:

“The Red-breasted Nuthatch, which coexists with the Black-capped Chickadee throughout much of its range, is able to understand the latter species’ calls. The chickadee has subtle call variations that communicate information about the size and risk of potential predators. Many birds recognise the simple alarm calls produced by other species, but the Red-breasted Nuthatch is able to interpret the chickadees’ detailed variations and to respond appropriately.”

As Steve Martin might say, “Those nuthatches — they have a tool for everything!” Is there an animal behaviorist out there who can help us out?
