Bird photos

I am learning how to use the combination of K20D, FA* 300mm f4.5 and 1.7x AF Adapter. Here are some humble attempts with shooting birds. Some of the images have been cropped quite a bit. What do you think?

Very nice and sharp. I like 2 & 5 the best as they are the most interesting images, though I do appreciate 1 as I never seem to be able to expose these correctly (usually get a black bird against the sky).

I'd be very pleased with all of them.

Good set, Bjolester.
Nos. 2 & 3 for me, for the graphic quality of them both.

Thank you Lee and Roger for your kind and helpful comments! I find shooting birds quite a difficult task, but I guess practice over years will give results. When attempting to take photos of for instance the Heron, I find it extremely difficult to get close enough. I guess I have to do some studying of field techniques (how to move in the terrain quietly) and appropriate clothing. Most often my Heron images end up like this
