Shade coffee plantations in Colombia are a critically important wintering habitat, supporting densities of warblers 3 to 14 times higher than those of neighboring primary forest. Cerulean warblers nest and raise their young in large tracts of deciduous hardwood forests that have tall, large-diameter trees and diverse vertical structure in the forest canopy. Gaps in the forest canopy or small forest openings appear to be important. During the nesting seasons of 2003 - 2005, hundreds of points on private lands were surveyed. They will breed in smaller forested stands in areas where the larger landscape is well-forested. They’ll finally settle for the winter in the tropical Andean forests of Colombia, Venezuela, Ecuador, and Peru. Email: MidwestNews@fws.gov. They search for and take insects from the base of leaves and the foliage of many different tree species. In the episode "The Big Picture" of the Curious George TV show, a book about the cerulean warbler by The Man in the Yellow Hat is published. Their nests are cup-shaped, and are placed on a horizontal branch high in a hardwood tree. Similar to breeding habitat, multiple layers of vegetation in the forest canopy appear to be important. Find a location or office  The American Bird Conservancy (ABC) is working with its Colombian partner, Fundación ProAves, to protect wintering habitat for cerulean warblers and other migrating songbirds. Only one brood of young is raised annually, but the pair may renest if their first nest is destroyed. The mission of the U.S. This traditional farming technique is at risk as coffee prices fluctuate and pressure to switch to higher-yield sun coffee or other crops intensifies. The Midwest Region includes Illinois, Indiana, Iowa, Michigan, Minnesota, Missouri, Ohio and Wisconsin. The rate of clearing is declining Did you know that the United States shares many migratory songbird species with our neighbors in Central and South America? U.S. While many private woodland owners across the region have an excellent record of forest stewardship, irresponsible timber harvesting has been the norm, rather than the exception, for decades. This species may prefer primary forests with older-growth conditions, but has been found in second-growth forests and shade-grown coffee plantations.

Females and immature birds have greyer or greenish upperparts, a pale stripe over the eye, and no streaking on the back and no neck. Dendroica caerulea (Wilson, 1810) (unjustified emendation). absorbing greenhouse gases and stabilizing the local climat, Cerulean Warblers Link Conservation on Two Continents, Recording Cerulean Warblers with Charlotte Goedsche, Audubon and the Ruby-throated Hummingbird. In fragmented forest areas, this bird is vulnerable to nest parasitism by the brown-headed cowbird. Although sizeable populations can be found throughout their migratory range, approximately 80 percent of the Cerulean Warbler population breeds in the forests of Appalachia in Tennessee, Kentucky, West Virginia, Ohio, and Pennsylvania. The data are being used to test and refine predictive models on the spatial distribution, abundance, and habitat associations of cerulean warblers in their core breeding range.
