Behavior

Movement

The rufous sabrewing is thought to be mostly sedentary, though it may make elevational changes or move about seeking nectar sources.

Feeding

The rufous sabrewing forages for nectar at a variety of flowering plants, shrubs, and trees, though its diet has not been greatly studied. In mostly stays low, often in the understory, but will forage as high as the canopy at the forest edge. Males defend nectar-rich feeding territories. In addition to nectar, the species feeds on small insects captured by

in dense understory. Females make a small cup nest of moss lined with thistle down and covered with lichen; some of the moss hangs down as a "beard". It is placed on a thin branch, usually an exposed one within about of the ground. The female incubates the clutch of two eggs for 15 to 16 days and fledging occurs 23 to 26 days after hatch.

Vocalization

The rufous sabrewing's song is "varied, strong, squeaky chipping and chattering, also short, rich, warbled phrases." It also makes "a shart, nasal ''squihk'', a slightly more metallic ''pli'ik'', and a hard, chipping ''chi'ilrr chik-chik-chik-chik''" calls.

has assessed the rufous sabrewing as being of Least Concern. Though its population is estimated at 20,000 to 50,000 mature individuals, it has a restricted range and the population is believed to be decreasing. No specific threats have been identified. Mexico considers its "a species under special protection" but there is no conservation program for it.
