A new study in mongabay.com's open-access journal Tropical Conservation Science looks at a particularly endangered guan: the Cauca gaun (Penelope perspicax).


To determine how the Cauca guan is faring, a team of scientists led by Gustavo H. Kattan, counted guans across three forests.


The researchers found that the Cauca guan inhabits both primary and secondary forests with around 10-18 guans per square kilometer in two of the sites. However, a secondary forest in Bremen sported a remarkably high density: over 42 birds per square kilometer. The scientists write that this density is comparable to densities of small passerines or songbirds.
