Agonistic Behavior

Physical Interactions

Individuals may chase conspecific territory intruders (10).

Communicative Interactions

When a threat is perceived, birds can raise the short crown feathers, displaying their white crown. Threats can include a human intruder approaching a nest, or a territorial threat from a conspecific (10). When facing a conspecific, the bird that raises its crest the highest is the dominant individual, and successfully chases the other (10).


No information.

Sexual Behavior

Very little information, but presumably is socially monogamous.

Social and Interspecific Behavior

Degree of Sociality

Often forages alone, in pairs, or in small family groups of 3-4 individuals (10, 2).

Nonpredatory Interspecific Interactions

Sometimes forages in mixed-species flocks (2, 21); flock associates include tit-spinetails Leptasthenura sp., Black-crested Tit-Tyrant (Anairetes nigrocristatus), and conebills Conirostrum sp. (19).
