The proofs for one of my books arrived the other day, so I have been busy busy busy. This (in part) explains the lack of action here on the blog, and the preponderance of recycled stuff. Sorry about that. In fact, sorry, here's another recycled article from Tet Zoo ver 1. Hopefully I'll have the time to produce some new content over the next week, but don't hold your breath. And sorry about all the dinosaur stuff: I know you much prefer it when I post on frogs, lizards, mice and passerines. Anyway...
As a kid I always got the impression from textbooks that the only tetrapods (and thus only animals) that engage in play behaviour are (1) mammals and (2) a few really smart birds, like corvids and some parrots [Kea Nestor notabilis shown here]. Raptors are also known to engage in play behaviour, with it being relatively well documented that adults will drop feathers in front of their flying juveniles. The juveniles catch the feathers as if they're pretend prey.
