The Long-wattled Umbrellabird Cephaloterus penduliger is a Chocó endemic specialty whose conservation status has been raised to vulnerable due to the destruction of his habitat.  The situation at 23 de Junio is no different, the leks are vulnerable due to deforestation and need help!

Below is the abstract of the study performed by Carlos Morochz from August of 2009 to April of 2010 (8 months) in which they found two leks about 3 km apart and at different altitudes.  One lek was found at SO 02 07.9 W78 52 53.8 at 1181 m.a.s.l. which is near the town of 23 de Junio, and the other was found at SO 03 28.0 W78 51 37.6 at 1546 which is on the hills to the west of the town.

Unfortunately there are no protection measures to assure that these leks will remain. 


The Long Wattled Umbrellabird (Cephalopterus pendullger) is one of the lesser known species within the family Cotingidae in Colombia and Ecuador. So far we have only information about distribution of seeds and nesting behavior. It is a dispersed lek-forming species that met four conditions: (a) There is no parental care by the male (2) the males gather in specific places to carry out displays (3) in lets resources that females are found consist of the male genes, food and nesting sites (4) The females are the only ones who choose their partner These four conditions are limited each depending on the type of habitat that provides the location and area of Lek In the study on the Cooperative 23 de Junio we use leks methodologies to find and analyze the behavior of the species to know more about its basic biology. It was found that the species is dependent on the type of habitat and food availability. The study site is a secondary habitat, fragmented and grasslands at which the species is threatened and is susceptible to small changes in the environment. We use a program of maximum entropy (Maxent) where we predicted the distribution of fundamental ecological niche that matches the expected for the species. Then comparing to the rate of deforestation in Ecuador the area of witch C Penditttger needs, decreases by 74% which suggests that necessary measures are needed for conservation and species protection and reforestation projects.
