Keywords:
circadian migrations, nycthimeral rhythms, Psittaciformes, roostingAbstract
The yellow-naped parrot, Amazona auropalliata has established wild populations adapting to urban environments. In this note we present the results of the recording of individuals on their routes to communal roosting. Observations were made between April 2020 and March 2021, from four sighting points in the northeast of the city of San Salvador, an average of 35.76 min, for a total of 170 counts, and a total of 100.06 hours. The results showed an average of 2.42 individuals in 125 successful observations, with an occurrence between 17:26 and 18:29 hours, with more records in the period from April to July, when the species is not breeding, there are more juveniles flying and weather conditions are favorable for observation Spearman’s correlation analysis between sunset and parrot passing time (R2 = 0.26) shows that evening movements are not influenced by sunset.
