The avesperu package provides access to the most up-to-date and comprehensive dataset on Peru’s avian diversity. As of June 23, 2025, the list includes 1,914 bird species, reflecting significant taxonomic changes and updated validations based on recent scientific publications, photographs, and sound recordings deposited in accredited institutions. The classification follows the guidelines set by the South American Checklist Committee (SACC).

Species Categories

Each species in the dataset is classified into one of the following categories, reflecting its status in Peru:

X Resident: 1,545 species
E Endemic: 119 species
NB Migratory (non-breeding): 139 species
V Vagrant: 85 species
IN Introduced: 3 species
EX Extirpated: 0 species
H Hypothetical: 23 species
