I was probably 10-15 feet away from these birds and they were cropped to vertical. I've been having problems with jays getting too close and not being able to fit the whole bird in the frame, as witnessed by this jay shot.
I don't use a blind for bird photos. I had a feeder in a tree for these and just sit still until the birds get halfway used to me. Sometimes it works, sometimes it doesn't go so well.
I probably take 20 shots to get one decent one - especially when the light is poor and I have to use slower-than-I-want shutter speeds.
