Very little detailed information. Azure-crowned Hummingbird forages and perches from the understory to the canopy. Howell (1972) described these hummingbirds, in the pine savannas of northeastern Nicaragua, "hovering around clusters of pine needles [and] before bark crevices", where they may have been searching for arthropods, as well as visiting flowers, including of epiphytes.
Little information. Sometimes Azure-crowned Hummingbirds are territorial, but depending on the abundance and availability of resources, these hummingbirds also may follow foraging routes.
Little information. Azure-crowned Hummingbird presumably is polygynous, as are most if not all species of hummingbirds (Schuchmann 1999: 509).
Social and interspecific behavior
Azure-crowned Hummingbird usually is solitary, as is typical of hummingbirds, but may aggregate at flowering trees (Howell and Webb 1995).
No documented reports of predation on Azure-crowned Hummingbird?
