I noticed some birds in a tree near my house and tried to take a few shots of them. It was almost sundown and the tree was in the shade so light was definitely an issue. I also had to use a fairly fast shutter speed because the little guys are fast and wouldn't hold still. Both were taken at ISO 1,000 F/8 with my 55-300mm and are pretty hevily cropped. Are they too noisy? I didn't want to lose any sharpness by opening up the lens but I may have been better off.
