1 is a tad bit over exposed, the composition is not bad but i would go tighter on the flower, focus is good
2 is not bad but doesn't really do anything for me
In 3 were you going for the out of focus bird and blurred wings? If so, that would work but I think you need to be in tighter on the bird.
4 is the best, though a tad underexposed and would be nicer if you weren't shooting down on the bird. and again, get a little closer in, or try a crop.
thanks for the reply
ill keep that in mind about gettin more level with the bird on the ground.
oh.. and #3 was kinda an accident- i was shooting in low light and the flash freaked the bird out
Also, keep in mind that you should generally be trying to eliminate lots of space around your subject.........try and fill the frame as much as possible. With birds it is hard because you're limited, but if you do this, you're pictures will have more interest and draw the viewer in.
