On the wintering grounds in South America, the preferred habitats of Cerulean Warblers occur in a landscape that is also ideal for human settlement and agriculture, notably the production of coffee, cacao, tea, hill rice, and coca (Robbins et al. foliage stratification, gap distribution, tree species distribution) may be an important predictor of breeding habitat suitability for this species.

Cerulean Warbler (Dendroica cerulea) is a small wood–warbler (family Parulidae) that breeds in a few areas in southern Ontario and southwestern Quebec. Individuals have been observed in lower montane wet forest in Belize (Parker 1994), as well as in primary and secondary forests in Guatemala (Land 1970), Costa Rica (Stiles and Skutch 1989) and Panama (Ridgely and Gwynne 1989). 0000001778 00000 n x��W�r�6�kF��%��ēĮ�yک:���,�.h�V�ڤKY���{. )j�2h�E�NH���[�-���3_:3�Z,� R5qq��on�|̃��f This needs further study.
