The extended reserve protects the warbler wintering area

Conservation groups have more than doubled the size of a conservation area in Colombia that is an important wintering area for the Prothonotary Warbler.

The organizations – Rainforest Trust, World Land Trust, Saving Nature, American Bird Conservancy and Fundación Biodiversa Colombia – have added 3,839 acres to the El Silencio nature reserve in the central Magdalena Valley in Colombia. The reserve now covers 6,844 hectares.

Colombia is the second most biodiverse country in the world and the central Magdalena Valley is one of the most diverse regions. Not only is it a critical habitat for migratory birds, but it is also home to six primate, 345 bird, 42 amphibian and 723 vascular plant species.

The extended reserve will enable the protection and connection of the two main forest areas in the region through wildlife corridors, creating the largest contiguous forest expansion in the valley’s lowlands. This habitat is of great importance for the endangered brown spider monkey (one of the rarest primates on earth) and the blue-billed curassow, as well as three other threatened and endemic species of monkey, lowland tapirs, big cats including jaguars, over 300 species of birds, endangered hardwood trees and other wild living animals.

The same riparian forests in El Silencio are important wintering areas for prothonotary warblers that nest in the eastern United States. In a study published in The Condor: Ornithological Applications in 2019, Ohio State University’s Christopher Tonra and colleagues examined geolocator tag data from Prothonotary Warblers and found that the Magdalena River Valley area was the most common in winter relaxed.

In 2020, a blue bill curassow was videotaped along a path bordering a forest restoration plot in the El Silencio Reserve.

“This is very exciting, not only because it proves the success of the restoration goal, but also because it is very close to the research station, which makes it easier for us to study and observe the species,” says Fernando Arbalaez, managing director of Fundación Biodiversa Colombia.
