i Have a few other pics at the same setting. Pl comment on them also.
Your 2nd example does look quite good. Nevertheless, using a faster shutter speed as others have noted is always a good idea, both in terms of being at the limit of what SR can do at long focal lengths, and the subject movement. Even when a bird moves its head or body slightly, they move with great speed.
There's also the matter of greatly reduced depth-of-field in long tele shots, especially when not at or near infinity focus. Even a slight body movement by you as you press the shutter release can throw focus off. The reduced DOF alone is a good reason to stop down, preferably to at least f/8 while maintaining higher shutter speed. This means a boost of ISO setting, which in good lighting will not likely be excessively high. At a moderate distance with a 300mm FL, f/8 will probably adequately defocus the background, otherwise to shoot at f/5.6 it is best to use a tripod as normhead suggests, if that is practical for you.
