Fire is a factor of particular concern in western North America with regard to managing hummingbird habitats.

Fires impact hummingbirds by affecting nesting substrate, foraging resources (nectar and other foods), predation, migration habitat, wintering habitat, and presence of invasive plant species. Characteristics of fire that are important for hummingbird conservation include: spatial, temporal (seral/successional stages), severity, vegetation/habitat type (e.g., forest, shrubland, desert, etc), and historic fire regime (which incorporates many of the other factors). Fire management practices, such as prescribed burning and post-fire restoration, can have significant effects on the regeneration of nectar resources and could be developed as a valuable management tool for enhancing and restoring hummingbird habitats.
