I like them tim.
#1 is an interesting shot with it feeding but the sun spots/halos on the wave pulls your eye away. A wee bit central but hey ho.
#2 Those sunspots again
#3 I like this one and it looks even better on your Flickr.
#4 The best of the 4 in my opinion. The bird in the background gives it a bit of depth, even though the whites have blown a bit, but nowt that would spoil it.
Nice one.
