Weight, Diet, and the Amazon Liver
Amazons love food, advertise that love loudly, and gain weight more readily than many parrots — especially the classic perch-potato bird that eats a seed-heavy bowl and flies little. Excess weight in an Amazon is closely linked with fatty change in the liver, which can progress quietly while the bird still looks cheerful and eats enthusiastically. Weigh your bird regularly and feel the breast: the keel bone should be palpable without being sharp, and a breast that bulges on either side of it is a warning. A vet-guided move toward a measured, varied diet with more vegetables and controlled seed, plus daily out-of-cage activity and flight or climbing where safe, addresses the root rather than the number alone.
Vitamin A Shortfall and Breathing Signs
A long-running seed-only pattern is also low in vitamin A, and in Amazons that shortfall tends to show in the surfaces of the mouth and airways: thickened or crusty nostrils, white plaques inside the mouth, a duller beak and skin, and a bird more prone to respiratory infection. Breathing signs in any Amazon — wheezing, voice change, sneezing fits, nasal discharge, or a tail bob at rest — deserve a prompt avian vet visit, because Amazons are among the parrots in which a fungal respiratory infection is a recognised concern, and early cases are far easier to help than advanced ones. Keep the living area clean and well ventilated, avoid smoke and sprays entirely, and treat dusty, damp housing as a health issue, not a housekeeping detail.
Feathers, Feet, and Behaviour
Feather-damaging behaviour — chewing, barbering, or plucking, particularly over the legs and chest — appears in Amazons that are bored, under-stimulated, hormonally frustrated, or uncomfortable, and medical causes should be ruled out before it is labelled purely behavioural. Feet suffer when a bird spends its life on one smooth perch of a single diameter: look for red or sore areas on the soles, overgrown nails, and reluctance to move around the cage, and offer varied natural perches and a flat resting surface. Seasonal hormonal behaviour, with regurgitation, territorial defence of a chosen person or space, and louder vocalisation, is normal in rhythm but worth discussing at a wellness visit if aggression or chronic egg-laying enters the picture.
The Long View for a Long-Lived Bird
Amazons commonly share several decades with their owners, and the problems above are slow diseases of accumulation — diet, inactivity, and environment compounding year after year. That makes the annual wellness visit, periodic blood work as your vet advises, and honest home records unusually valuable: a weight creeping up across three visits, or breathing that is fractionally louder each winter, is visible in a record and invisible in memory. Raise changes early rather than waiting for an unmistakably sick bird, because an Amazon that stops eating or breathes hard is already well into trouble. Maintaining your Amazon's weights, diet changes, and blood results in KinsLe's Pet Passport builds the long health story this long-lived species actually needs.
