With the objective of determining the diversity of the bird community associated with the areas undergoing natural regeneration, the mining zones and the open gold and platinum sky in Condoto, Chocó, Colombia, sampling was carried out, using methods such as censuses and captured with fog networks, between 06:00 and 18:00 hours. There were 662 individuals, distributed in 10 orders, 22 families, 49 genera and 62 species. The order Passeriformes had the largest number of families and species. At the family level Thraupidae (S:11), Tyrannidae (S:9) and Trochilidae (S:9) were the richest families. The species saturation curve exhibited a different pattern in each of the scenarios, where 73% of the estimated richness was recorded, a factor that was attributed to the characteristics exhibited by each sampled area. In relation to diversity scenario 1, the greatest diversity (H’=3.4) was recorded, as well as the greater skin fairness (0.90) and lower dominance (D=0.04). No threat species were recorded. Finally, three migratory species were registered, which ratifies the tropical rainforest as an important migratory center for birds, where, thanks to the variety of ecosystems, scenarios are provided to house a variety of birds that reach these ecosystems to comply with their Post reproductive processes.
