Please help me identify this bird?

I live in Boston, and my friend found this baby bird on the side of the road. Does anyone know what bird this is? Any advice on how to take care of it?

Possibly a Northern Mockingbird?

First advice is to 'park' it in a bush off the ground close to where you found it, and see if its parents return to feed it. Very likely yes; if not, then you may need to feed it yourself.

Food: chopped mealworms and a little bit of soft fruit would be ideal. Cat food would be OK for a short stop-gap until you can get some mealworms.

Most important though is to get it to a trained licensed rehabber as soon as possible; caring for a young bird like this isn't easy (the 4 a.m. first feed of the day is a bit daunting!)

Mine was a bit older, but I know for sure it was a mockingbird as the angry parents were right behind my head on a branch squawking their displeasure about me photographing their offspring. Hopefully my image will help with the i.d.
