Introduction: There are no previous studies about the Achiote Interurban Biological Corridor, Costa Rica. Objective: To characterize birds and land use to improve the corridor’s functional connectivity. Methods: We selected ten sampling sites (sugar cane and coffee cultivation areas, urban areas, secondary forest, and riparian forest) and used the point count technique for six months (100 sampling hours and 120 samples). We determined bird richness and abundance associated with each type of cover. Results: We identified 194 bird species. Secondary forest, riparian areas, and coffee plantations had the highest diversity. Trophic guilds and habitat use were not related to cover, and insectivores and frugivores were generally dominant. Conclusion: Birds with generalist habits predominated in open areas and forest patches within the biological corridor.
