What is a good textbook of Ornithology to begin with?

Thank you.

There is a good textbook called just Ornithology by Frank Gill which I would really reccomend. It is very well written and will give you a comprehensive overview of the subject. I have the third edition which I like a lot.

Sadly it seems to be out of print at the moment which probably means they are about to issue a new edition. However, the third edition can still be found on Amozon and probably other places online.
