Herein we report cases of leucism in Molossus molossus and Sturnira bakeri from three locations of lowlands of western Ecuador, which include three gravid females, five juvenile, four subadult, and six adults. The M. molossus specimens showed white spots on several parts in the soft part of body (ears, tragus, propatagium, uropatagium), and fur (throat, abdomen), while individual of S. bakeri presented a whitish-yellowish patch on its dorsal region, very contrast in yellow-shoulder bats. Although South America has a significant information gap about chromatic disorders in bats, been necessary to continue reporting cases of chromatic disorders to try to determine their causes.

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.

We present a case of chromatic disorder observed in a specimen of Trachops cirrhosus from lowland forests of the Ecuadorian Amazon. During the field work, six individuals of this species were captured with mist nets in an intervened habitat, of which, a juvenile male specimen was distinguishable from the rest of the individuals due to the presence of whitish spots on the ventral region, on the chest and abdomen. We discuss the previous reports of this type of pigmentary disorders in bats from Ecuador, and in the Neotropic, documenting the first record of Trachops cirrhosus with this condition for the country.
