Dear Christina,
Thank you for sharing. This is another good tips apart from 'The Ten Steps to Perfect Photographs' recommended by hkwongkit quoted as :
1. Ascertain where the birds you want to photograph live.
2. Go there before sunrise. You will scare them off when you arrive.
3. While you wait for them to come back, get your camera ready. Small apertures give in-depth focus but require slower shutter speeds. Use a tripod. If you have a gigantic telephoto lens, point it where you expect the bird.
4. Remember the rule of news photographers: “F8 and be there.”
5. Sit down and don’t move; the birds will return after they get used to your imitation of a tree.
6. Sit still some more. Don’t scratch that itch.
7. Ask yourself the big questions.
8. Answer them. You have plenty of time.
9. After the birds return, slowly, ever so slowly, raise the camera to your eyes or lower your eyes to the tripod.
10. Focus and trip the shutter.
