Nest boxes provide critical breeding habitat for cavity-nesting birds in landscapes where old trees and natural cavities have been lost, contributing directly to individual bird welfare and population recovery.
Nest box schemes are one of the most accessible and effective wildlife welfare interventions available to individuals. By providing nesting habitat that has been lost through woodland management, urban development, and building renovation, nest boxes enable birds to complete their breeding cycle with significantly better welfare outcomes than birds that cannot find suitable cavities. Welfare during breeding includes protection from weather, predation, and disturbance - all of which nest box placement and design can influence. When combined with appropriate vegetation for food, nest boxes create genuinely wildlife-friendly gardens that contribute meaningfully to urban bird welfare and population maintenance.
