Answer 1

Feather-plucking occurs in many bird species world-wide for a variety of reasons. Wild birds pluck feathers to maintain appropriate body temperature. Domestic birds and pets can also display forms of this behavior for both thermal or psychological reasons. Birds kept in cages may be showing emotion through the feather-plucking habit, possibly owing to lack of appropriate environmental stimulation. Feather-plucking may indicate the bird feels neglected, sad, bored, or inappropriately expressing joy.
