Today's growing interest in companion and aviary birds presents a challenge to the practitioner to implement rational veterinary care. A complete and cautious physical examination aided by proper restraint is necessary in the diagnosis of cage bird diseases. Clinical examination can be difficult due to the nature of the birds and their small size.
