About Cerulean Warblers2019-03-26T05:27:25-04:00

The Cerulean Warbler is a small bird of the deciduous forest treetops, the sky-blue Cerulean Warbler can be difficult to see. Cerulean Warbler is one of the species of highest concern in the eastern United States because of a small total population size and significant declines throughout its range. The North American Breeding Bird Survey estimates a decline of over 2.6% per year between 1966 and 2015, resulting in a cumulative loss of 74% of the population in that time. Partners in Flight estimates a global breeding population of 600,000, with 98% breeding in the U.S., and 2% in Canada. It is a Tri-National Concern Species and a U.S.-Canada Stewardship species and rates a 15 out of 20 on the Continental Concern Score. Cerulean Warbler is on the 2016 State of North America’s Birds’ Watch List, which includes bird species that are most at risk of extinction without significant conservation actions to reverse declines and reduce threats. It is listed as Vulnerable on the IUCN Red List.

By 2080, this already declining Neotropical migrant is projected to have 98 percent of its current summer range shifted away from the current core, but it has potential to expand in the north, according to Audubon’s climate model. Mature hardwood forests that the bird depends on may not exist to the north and the forests expansion may not keep pace with the changing climate.

It nests and forages higher in the canopy than most other warblers. They breed in forests with tall deciduous trees and open understories, such as wet bottomlands and dry slopes. The Cerulean Warbler winters in broad-leaved, evergreen forests.

On the wintering grounds in South America, the Cerulean Warbler usually is found in mixed-species foraging flocks, associating with tropical tanagers and other resident species. When renesting after a failed first nest, the female often uses spider web from the old nest to start construction on the new nest. Fresh lining is gathered for the new nest, but spider web may be too valuable and time-consuming to waste. The female Cerulean Warbler has an unusual way of leaving a nest after sitting on it a while. Some people call it “bungee-jumping.” She drops from the side of the nest, keeping her wings folded to her sides, and opens her wings to fly only when she is well below the nest.

Lack of suitable habitat is the reason the Cerulean Warbler is the fastest-declining songbird species in North America. Only about 1,000 birds are found in Michigan each year. Barry County is one of the few refuges that remain for the Cerulean Warbler in Michigan. These birds require connected forests greater than 2,000 acres in size. Birders and researchers recognize Barry County as Michigan’s top spot for observing the Cerulean Warbler. Each spring, these songbirds migrate to the vast hardwood forests of the Yankee Springs and Barry State Game Areas. The fans of the Cerulean Warbler are never far behind!

Restoration Efforts for Plant and Bird Communities in Tallgrass Prairies Using Prescribed Burning and Mowing: Lessons from Iowa on the responses of two management techniques in fragmented tallgrass prairies by Dr. Fred Van Dyke
Recent losses and fragmentation of tallgrass prairie habitat to agriculture and urban development have led to corresponding declines in diversity and abundance of bird and plants associated with such habitat. Mowing and burning are two management strategies for restoring and rejuvenating prairies in fragmented landscapes, but their specific, comparative effects are the subjects of ongoing evaluation. In this presentation, you will see comparative results of responses of plant and bird communities on four sets of mowed, burned, and untreated sites of small (3–10 ha), fragmented tallgrass prairies at the DeSoto National Wildlife Refuge in Iowa during bird breeding seasons and learn the implications of the results for conservation of both grassland plants and birds.

Dr. Fred Van Dyke is Executive Director of the Au Sable Institute, a Christian institute of environment study and conservation engaged in conservation education research, community building, and engagement of the Church in the work of conservation. Fred’s career in environmental conservation has spanned positions in academia, government research and management, and private consulting.
