One of the real pleasures of my brief trip to Boston was the chance to spend a morning wandering around the Arnold Arboretum. For those unfamiliar with this venue its a short tube ride from central boston and is a marvellously landscaped collection of trees and shrubs. The roughly rectangular site is bisected by a meandering two mile road that winds up and down across the site. The arboretum is really well laid out and a must visit for nature lovers in Boston. As well as having some truly wonderful trees, of which more later, the Arboretum seems to be maintained in a fairly naturalistic fashion with grass allowed to grow to its full potential and attract a lot of wildlife. In addition to some very nice birds (I'm rather jealous of you east coast bird feeders) there were also a number of mammals (I suspect a fair few amphibians and reptiles too but I didn't manage to find any). The highlight for me were the beautifully patterned Chipmunks. They were far more arboreal than I expected wandering through tiny thin shrub branches but not very helpful to an underequipped photographer. I did see this one bolt down its hole though.
I had hoped if I waited long enough he'd get comfortable and come out but his natural wariness outweighed my natural patience so we watched each other from a safe distance and called it a draw. I have no idea which species this is so if anyone is familiar with the mammals in this region and knows I'd be most grateful.
