title: Data from: Cultural burden of wild pet ownership causes selective parrot defaunation despite habitat restoration efforts in Costa Rica

description: Aim Human population growth and resource overexploitation have induced
 major changes in global biodiversity. Costa Rica, with 26% of its land
 area protected, is considered a good example of environmental
 conservation. However, measures taken focus mainly on habitat
 preservation, while overharvesting is also a major driver of wildlife
 decline. Neotropical parrots seem to be affected by both habitat
 degradation and poaching, providing an interesting model to study the
 combined effects of these threats. We test how different levels of habitat
 transformation influence parrot presence, abundance and richness, as well
 as the effects of illegal extraction of individuals to supply domestic pet
 demand. Location Costa Rica Methods We conducted a large-scale survey
 across the country to simultaneously obtain data on the relative abundance
 of parrots in different habitats and estimate parrot poaching by recording
 illegal household pets. Then, we related parrot presence, abundance and
 richness to habitat characteristics using two complementary approaches:
 patches along transects to assess habitat characteristics based on
 information from road transects and all georeferenced points where we had
 detected at least one parrot to calculate point-level presence, abundance
 and richness. Results We found a high abundance and richness of parrots in
 habitats with intermediate levels of human transformation and an
 overwhelming number of illegal parrot pets. Main Conclusions Costa Rican
 parrots tolerate some degree of human-induced habitat transformation but
 are unable to withstand overharvesting, mainly the preferred species
 (amazons and macaws). Habitat protection is partially effective in
 conserving parrots and should be combined with actions to halt illegal
 harvesting to restore parrot populations and their ecological functions.
