Accipiter bicolor is a widely distributed Neotropical raptor but knowledge about its ecology is poor, particularly in urban areas. In this work, we document the presence of A. bicolor in the city of Guayaquil and in nearby forested areas, in addition, we provide new records on its diet and discuss possible foraging strategies in synanthropic environments. Also, reports of this species are considered on citizen science platforms. Accipiter bicolor was observed consuming an individual of Columbina bluckeyi and another of Artibeus fraterculus; near a colony of this species of bat. Finally, we found 59 records of A. bicolor between 2007 and 2022 for Guayaquil and its surrounding areas, 14 records were in urban habitats. Observations in different urban and peri-urban habitats are discussed, as well as their feeding habits.
