Nice shots, would be nice to know what kind of bird is #1. This information is always of interest to those of us who chase birds around trying to get good photos of them. Two comments: 1) these images look oversharpened - I am not sure whether this is a result of post-processing or a happens because of the conversion process to get them down to a size for web publication. 2) watch your foregrounds and background - in the first one, you have OOF branch in front of the bird, but the blue background is okay. In the second one, your background is a bunch of pink blossoms, which is okay for this bird as it is quite dark-coloured, but may not necessarily be suitable for other birds.
