Biology

The lazuline sabrewing is poorly understood and requires detailed study (6). Individuals from the Perija mountains of Venezuela and Columbia have been observed in breeding condition in June (2). Females of other sabrewing species are known to lay two white eggs in relatively large cup nests on low horizontal branches, usually over streams (4), and it is likely that this species displays similar reproductive characteristics. The lazuline sabrewing feeds on nectar, reached with its long curved bill from flowering ericads, such as Heliconias and Hibiscus (2) (4) (5). Additionally, insects are caught from the air and gleaned from foliage (2).
