Parrots are sensitive creatures whose intelligence is often grossly underrated and, as a result, frequently exhibit behavior that is misunderstood by their owners. This reference guide to owning a parrot answers questions about problems and tensions between these feathered creatures and their owners. The basic elements of parrot psychology are explained, as are environmental factors that can cause biting, screaming, and feather plucking. Case studies of specific relationships are used to illustrate both good and bad examples of the pet/owner relationship.
A book worth reading, authored by one of the most knowledgeable people regarding parrot. This book covers various behaviours, issues, illnesses etc, and does so with evidence/cases. It doesn't focus on one species of parrot and is very good to get a wide, general knowledge.
