Oh ya, totally agree, you have to take LOTS of pictures. A day that does not have really bright sunshine is good. I like to have my back to the sun if it is a sunny day, but in the waning sunlight, you have to be careful of the shadow of yourself. Compared to when the sun is high in the sky and the shadow is not so easy to get. Winter is hard in that way. Do not use a flash unless it is a dark day. I never have my flash on, only if I am inside and it is dark. A fast shutter speed is good too, but as said, it requires more light. I don't know a lot about photography, but have a very nice pocket style Sony camera that takes absolutely marvelous pictures. It has a fast speed too. When I take a picture, it takes it that very second, not the delay that I had experienced before. Like when I pushed the button and it took like 1 to 2 seconds to take a picture. That was very annoying and I lost a lot of time, whilst something moved, sigh. A bad picture result. I think you can get cards to enhance speed of the shutter too, if I am not mistaken.
I have an excellent macro too, which is very nice for taking those close up shots. Calm birds help, smiling. Anything you can do to keep your birds calm. I like to, as many people do, get down and dirty with the birds. Rarely will I take a picture from a standing up position, unless it is something that can be taken standing up, like a picture of a thing that is not at ground's level. Sitting on a bucket, sitting on a milk crate, or plain and simply on my knees or squatting are the best shots. Right at the same level as the bird or other object.
You have had some excellent tips, and I am listening to these tips too. I really need to get out there and get some pictures of all my birds. Something I really want to get a picture of is the two buff orpington flocks of birds. They are in a pen side by side and there really is a difference between the hatchery stock and the breeder stock. When I get those pictures it will sure be a teller of that tale. Good picture taking, now get out there and get the pictures done, and show us what ya got!!!
Have a most wonderful and beautiful day, CynthiaM.
