The Pacific Screech-Owl (Megascops cooperi) occurs in a relatively narrow strip along the Pacific coast from southwestern Mexico (Oaxaca and Chiapas) to northwestern Costa Rica (mostly Guanacaste). It is a resident of dry forest types, and also mangroves locally, mostly in the lowlands but sometimes as high as 1000 m above sea level (Garrigues & Dean 2007, Holt et al. 2016). However, in December 2015 I took the accompanying photograph outside the town of Santa Elena, Costa Rica (Monteverde area), at an altitude of roughly 1300 m. The bird was shown to me by Adrián Arroyo, a local bird guide who had been aware of the presence of the species in this locality for at least two years. I have not seen any literature documenting this.
