Diversity, Volume 17, Issue 12

2025 December - 65 articles

Cover Story: Avian diets can be highly diverse but are often difficult to characterize, especially in small songbirds. Despite its widespread distribution, striking plumage, and nomadic movements in search of tree seeds, the diet of the Evening Grosbeak (Hesperiphona vespertina) has not been systematically characterized across its range. To address this gap, we examined more than 50,000 photographs of Evening Grosbeaks archived in the Macaulay Library. Foraging on natural food items was documented in 1075 images. Identified foods included at least 96 plant species from 25 families, one insect species, and two lichen species. Despite this high observed diversity, richness estimators indicate that additional dietary diversity remains undocumented. To our knowledge, this study represents the first range-wide analysis of a songbird’s diet using photographs from a community-sourced archive. View this paper
