The numbers of Yellow-headed Amazons coming to roost were much higher than the values recorded during the same months in 1992 – 1994. Throughout the 2013 season the roost counts averaged 85 ± 20 individuals per count which is much higher than the average of less than 15 from the same time period in 1992 – 1994. This finding is quite surprising given the reported grave status of this species in many areas of Mexico.
