Blue Dacnis Dacnis cayana




The Blue Dacnis is usually seen alone, in pairs, or in small groups, and will often join mixed species flocks of up to 12 individuals (Restall 2007). In Panama the average group size was determined to be 3.02 (Greenburg and Gradwohl 1985). It is described as foraging restlessly and nervously from the midstory to the canopy (Restall 2007). In Ridgely (1946) the Blue Dacnis is described as not being a very vocal bird. In captivity Blue Dacnis have also been observed anting (Skutch 1962b)

Sexual Behavior

The Blue Dacnis has been observed doing courtship displays, where males move restlessly from branch to branch and posture, doing things such as standing tall and bowing (Mitchell 1957). They are also known to engage in nuptial feeding (Skutch 1976).

Social and interspecific behavior

Blue Dacnis are usually found in pairs or in small groups. Blue Dacnis have been recorded in mixed species flocks with Cyanerpes, Tangara (Sick 1993), and Green Honeycreepers (Chlorophanes spiza) (Schulenberg 2007). Blue Dacnis are also known to join aggregations at fruit trees with the Red-legged Honeycreeper (Cyanerpes cyaneus) and the Shining Honeycreeper (Cyanerpes lucidus) (Wetmore 1965)
