Summary
Feather-picking and self-mutilation in parrots are stereotypic behaviors, possibly genetic. Early intervention by removing conflict triggers and environmental enrichment is key for successful treatment.
Area of Science:
- Veterinary Medicine
- Animal Behavior
Background:
- Feather-picking and self-mutilation are prevalent in psittacine birds.
- These behaviors are classified as stereotypic behaviors or obsessive-compulsive disorders.
- A genetic predisposition is suggested by overrepresentation in certain psittacine species.
Purpose of the Study:
- To define and explore the underlying causes of stereotypic behaviors in psittacine birds.
- To investigate the neurochemical basis of these behaviors.
- To outline effective treatment strategies for feather-picking and self-mutilation.
Main Methods:
- Literature review and synthesis of existing research on avian stereotypic behaviors.
- Analysis of potential etiological factors including genetics, environment, and neurochemistry.
- Evaluation of treatment approaches for feather-picking and self-mutilation.
Main Results:
- Stereotypies often arise from high arousal and the inability to perform natural behaviors, potentially due to absent stimuli.
- Neurochemically, these behaviors are linked to increased dopaminergic activity and dopamine turnover.
- Early-stage treatment yields the best outcomes.
Conclusions:
- Identifying and removing conflict sources, environmental enrichment, pharmacotherapy, and counter-conditioning are crucial for treatment.
- Addressing the root cause of conflict is paramount for managing stereotypic behaviors.
- Prompt intervention is vital for improving treatment success rates in affected birds.

Mate Choice
Mate choice—the decision about whom to mate with—is a type of natural selection, since animals must reproduce to pass down their genes. Mate choice is also called intersexual selection because the behavior occurs between the sexes.
Optimal Foraging
How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.
Types of Selection
Natural selection influences the frequencies of particular alleles and phenotypes within populations in several different ways. Primarily, natural selection can be directional, stabilizing, or disruptive. Directional selection favors one extreme trait and shifts the population towards that phenotype while selecting against individuals displaying alternate traits. Stabilizing selection favors an intermediate trait with a narrow range of variation. Deviation from the optimal phenotype towards an...
Conservation of Declining Populations
Conservation of declining population focuses on ways of detecting, diagnosing, and halting a population decline. The approach uses methods to prevent populations from going extinct.
Convergent Evolution
Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.The structures that arise from convergent evolution are called analogous structures. They are similar in function even if they are dissimilar in structure. Further, structures can be analogous while also...
