Abstract

Habitat fragmentation is a pervasive consequence of human land use, with profound effects on avian nesting behavior and reproductive success. This research paper synthesizes field studies and meta-analyses to examine how fragmentation alters avian nesting patterns, nest success, predator-prey dynamics, and community structure. We explore the mechanisms underlying these changes, including edge effects, patch size, landscape context, and nest site selection, drawing on global and tropical case studies. The findings highlight the importance of landscape-scale conservation, the vulnerability of certain nest types and species, and the need for multi-scale, long-term research to inform effective avian conservation in fragmented habitats.
