Fantastic colors, beautiful light, sharp, nice catch light. Might be a little to tight in the frame like to see more room on the left and need some CCW. TFS
Good critique from Gary. Nice low shooting angle, which accentuates the crouching posture of the bird.
re: thumbnail - as a member, if you host your image on BPN, you will automatically get a thumbnail. There is a glitch in the newest version of the hosting software (vB bulletin) which is causing thumbnail problems for images hosted off site.
So, for short term, just upload your images to BPN. Take about 30 seconds tops.
