Abstract

This study presents a comprehensive ecological evaluation of avian species based on 5,322 photographs obtained through camera-trap sampling. We identified 1,427 independent bird sightings, encompassing 26 families and 49 species. The study focused on temporal activity patterns, nesting behaviors, habitat preferences, and the overlap coefficient of activity patterns among 22 species of Passeriformes. Two species exhibited predominant morning activity, while five species were active in the afternoon, and 15 exhibited cathemeral activity (activity throughout the day). A cross-analysis revealed varying degrees of overlap in the activity patterns of pairs of species with similar behavioral ecology. Our findings indicate that despite exhibiting similar ecological behavior, these species display unique activity patterns, likely influenced by factors such as resource availability, competition avoidance, and thermoregulation strategies. The results highlight the richness and complexity of avian temporal niches and emphasize the need for further research into their correlation with environmental factors. This study contributes to a deeper understanding of niche separation within Passeriformes and expands our knowledge of avian behavioral ecology.
