Gloger’S Rule

The persistence of the coat color polymorphism melanism has been reported for several tropical felids, but its evolutionary advantages remain an active area of research. Few publications have explored melanism in the elusive species, oncilla (Leopardus tigrinus) within the Neotropical part of their range in Costa Rica. Herein, I present the first record of a melanistic oncilla within the montane cloud forest of Monteverde, Costa Rica. Recent studies have found support for theories (e.g. Temporal Segregation Hypothesis and Gloger’s Rule) explaining the ecological advantages driving melanism in oncilla and tropical felid populations. However, it is unclear what is driving melanism in this Monteverde oncilla population due to the singular observation. Further research investigating whether melanism is occurring at a higher frequency in other individuals in the region is critical to better understanding the occurrence of melanism in local populations of this cryptic species. The montane cloud forest in Monteverde provides critical habitat to this vulnerable species within the small Neotropical part of their range. Melanistic individuals may be particularly threatened by land-use change and increasing human pressure if theories for the evolutionary advantages and ecological conditions motivating melanism are supported.

Tropical Montane Cloud Forests

The tropical montane cloud forests (TMCF) of the Talamanca Mountains of Costa Rica are a unique and understudied habitat that is home to a high number of endemic bird species. Cloudbridge Nature Reserve is a TMCF reforestation reserve lying on the Pacific slope of Cerro Chirripó in the cantón of Pérez Zeledón. Here, we synthesize data collected at Cloudbridge between March 2016 and May 2020 from multi-year point count, walking, call-playback, and camera trap surveys along with photographs collected from February 2007 to April 2021 to present a bird species inventory of the reserve. In total, 204 bird species from 40 families, including 40 endemic species, were identified, and monthly presence summarized for each species. We discuss the implications of our findings for understanding TMCF avian communities, as well as the importance of year-round surveys using a variety of techniques to better capture overall avian diversity.
