I must admit I am not a birder, but I enjoy watching nature and birds are a vital part of our universe. Recently I obtained several guinea fowl. People say they are noisy, but for me that is their communication talking and each sound means something, though I must admit I don't understand them all yet, but I am learning. The warning of a predator is obvious and they do make a racket! They have been characterized as dumb, and I feel that term is a bit harsh. Perhaps if you observe their behavior we, humans, can reconnect with our earthly life sources. It takes time, so be patient.
This is an excellent database of Birds. The Cornell site of Ornithology is worth a view as well and there are materials for teachers.
