Major threats to Turquoise-fronted Amazon's conservation in the Impenetrable region, Argentina

Major causes of Turquoise-fronted Amazon's population decline include habitat destruction and capture for the pet trade. Deforestation and selective logging result in habitat loss. The extraction of chicks reduces the number of individuals and can reduce the number of available cavities for nes...

Deforestation and selective logging result in habitat loss. The extraction of chicks reduces the number of individuals and can reduce the number of available cavities for nesting. We evaluated the main threats that this parrot is facing in the Impenetrable region, Argentina. We estimated loss of cavities by deforestation, selective logging and poaching. We analyzed if chicks' removal and cavity repair affects the probability that a cavity is reoccupied. We estimated if chicks' removal affects nest survival. Deforestation and selective logging destroyed almost 20000 potential cavities per year. On average, chick's removal occurs in 486 nests every year. The probability of reoccupation was not affected by chick removal in those cases where the cavity was properly repaired. Most of nest exposed to removal had three (68%) or two (23%) chicks and in all cases were removed all except one chick per nest. In average 1.6 40-days old chicks were removed per nest. At 83% of cases the youngest chick was left at the nest. Nests subjected to extraction have a lower survival than non-extracted nests (73 vs. 93%). 2012 https://bibliotecadigital.exactas.uba.ar/collection/paper/document/paper_00733407_v27_n1_p39_Berkunsky http://hdl.handle.net/20.500.12110/paper_00733407_v27_n1_p39_Berkunsky
