Breeding grounds-- Cerulean Warblers are traditionally associated with forested landscapes, particularly mature deciduous forest with large and tall trees and an open understory (Hamel 2000a).They are found in both wet bottomland forests as well as upland locations on mesic slopes. Silviculture management decisions incorporate best management practices and guidelines when they take local forest structure into account. n�s�s�(�-@� ��@� In particular, core areas are dominated by bitternut hickory (Carya cordiformis), a species that is among the last to fully leaf-out in eastern Ontario. %���� As the Cerulean Warbler song does not appear to be particularly well suited for transmission in densely forested habitats (Woodward 1995), it is hypothesized that males are selecting these core areas to maximize song propagation (Barg 2002). 0000013724 00000 n Increasingly, biologists investigating the causes of these declines are focusing on habitat loss in the Tropics, where the birds spend the winter. 1996). 0000004134 00000 n And while the cerulean warbler’s status may be particularly precarious, it is just one of many migrants whose numbers have been falling for many years. startxref 0000027891 00000 n 4 0 obj <> 0000007434 00000 n c.

Second, because the nesting habitat requirements for both species are at opposite ends of the successional spectrum, because nesting habitat differs from post-fledging habitat,
