Good pics, 0487 (standing heron) is a bit overly compressed so it doesn't look as good as I am certain it does in the original. When you are showing a shot this big and with lots of detail, I always recommend going for closer to the 200Kbs limit that Pixalo allows and which is nearly always enough to show a picture at a good sharpness, this one is only 68kbs and is showing compression artefacts because of it.
Lovely combination of shots though, I think storks, herons, pelicans, egrets, etc are a great family of birds to capture as they have strong contrast between the softness of the feathered areas and the sharpness of their long beaks and lovely clear eyes.
Glad you're happy with your chosen camera and lens combo... even if it is a N****
Cheers,
