No such thing as 'just a bird' White-crowned sparrow I believe, decent shot too , sparrows can be very skittish. I chased around a few chipping sparrows this weekend for maybe half an hour, in and out of shadows , amongst the grass, Uggh !
Since the weather is slowly getting better I dusted off my D3300 and took it out to see what the TAM does with crop. It sure is a whole different world shooting the Tam at crop factor and I suffered "too much bird" at times but the shooting itself and the results were both a bit disappointing. Not that I can hold that against the D3300.
