Animals use foraging strategies to follow the food supply in these settings. The Orange-fronted Parakeet (Eupsittula canicularis) mainly inhabits the tropical dry forest of the Mexican Pacific to Northwest Costa Rica, although little is known about its diet and foraging strategies. Objective: To assess spatial variability in food resource abundance, diet, and foraging behavior of the Orange-fronted Parakeet in a modified landscape in Oaxaca Coast, Mexico. Methods: 30 phenology transects (200 x 6 m) were established during the dry season (February-June 2019) to measure food resource availability in primary deciduous, semi-deciduous, and secondary forests. The Orange-fronted Parakeets diet was determined by focal foraging observations, and dietary niche breadth and resource selection were considered to determine feeding strategies. Results: Orange-fronted Parakeets fed on fruits (42.3 %), seeds (29.3 %), and flowers (28.4 %) of 13 plant species and presented a broad dietary niche breadth with a higher frequency of foraging in primary forest. The Orange-fronted Parakeets select resources and adapt their foraging strategies based on food resource availability in each habitat. Conclusions: The study findings highlights the need to maintain the complete forest structure in a modified landscape to ensure food resources availability for Orange-fronted Parakeets during the breeding season. 2023 artículo científico 0034-7744 https://www.redalyc.org/articulo.oa?id=44975700018 https://www.redalyc.org/journal/449/44975700018/ https://www.redalyc.org/journal/449/44975700018/html/ https://www.redalyc.org/journal/449/44975700018/44975700018.epub https://www.redalyc.org/journal/449/44975700018/movil 10.15517/rev.biol.trop..v71i1.52180 en http://www.redalyc.org/revista.oa?id=449 Revista de Biología Tropical application/pdf Universidad de Costa Rica Revista de Biología Tropical (Costa Rica) Num.1 Vol.71 |
