Biology

The Juan Fernández firecrown feeds on nectar from a variety of plants, both endemic and introduced, preferring shaded flowers that are well above the ground (2). They also eat insects found on leaves or in flight (5). Both males and females guard feeding territories, which they defend by calling frequently from specific perches, flashing their crowns and threatening intruders by facing them in the air and hovering in place (6). Very little is known about the breeding habits of the Juan Fernández firecrown except that the nests are small and sheltered well above ground and it is thought that the breeding season is between September or October and December (6). Interestingly, there is a heavily skewed sex ratio within the remaining population, with three males to every female (5).
