Feather Picking in Psittacines

Feather picking is something you are likely to come across if you’re working with psittacines. While it may seem benign and cosmetic, feather picking can be an important sign of an underlying problem, either medical or environmental.
When faced with these cases, your first step should be a THOROUGH history.
Some important questions to consider (as well as standard husbandry/history):
- Is the bird housed alone? (If not, you will need to try and differentiate self-plucking or plucking by the cage mate).
- Describe the birds cage: size, substrate, perches, decorations, toys, location in house, location in room, noise level in area.
- Is the bird allowed to free roam? If so, is it supervised?
- What time do you turn off your birds lights; when do you turn them on in the morning?
- Have there been any changes to the birds life? (ie. moved house, moved cage, new people, new animals, less interaction time, less flight time, etc.)
- When did the bird start plucking?
- Has the bird plucked before? If so, describe (when did it start, how long, what feathers, when did it stop).
- Does the bird rub or scratch itself on cage objects?
- When does the bird pluck/chew? Does it interrupt other behaviours to do so?
- Is there cigarette smoke, air freshener, candle use in the home?
- Is the bird sprayed or bathed regularly? How often?
- Was the bird hand-reared or parent-reared?
- Does the bird have a favourite owner?
- Have any eggs been laid?
- When did the bird last moult? Describe.
- Does the bird have clipped wings? How long for?
Often, plucking is caused by a combination of factors. Therefore, it is important to identify as many as possible in order to resolve the issue.
Possible medical causes include: allergy, parasites, skin irritation, pain, reproductive disease, systemic illness (esp liver), PDD, air sacculitis, heavy metal toxicosis, solliculitis, malnutrition, neoplasia.
A thorough clinical exam should be performed after obtaining your history. After the physical exam, a full dermatological examination should be performed.
Unfortunately, the list of causes is too large to go into further detail. It is important to have an understanding of the different medical conditions that can lead to feather plucking in order to evaluate the history and physical exam.
With knowledge from the history and physical exam, you should be able to stream-line further diagnostics (ie. CBC, biochem, skin scraping, etc).
If husbandry can be improved, have a detailed conversation with the owner about what to change and HOW to change it. Send home handouts as there can be a lot to discuss.
If you want to hear more about any of the possible causes for feather plucking, let me know! I can do posts on those topics too.
As always, feel free to chime in and join the conversation.
