The blackpoll warbler is a fairly small bird which attains the weight of a ball point pen. document.write(unescape("%3Cscript src='" + gaJsHost + "' type='text/javascript'%3E%3C/script%3E")); The species appears to be quite a generalist, preying on a great diversity of adult and larval insects and spiders. They lay 3–5 eggs in a cup-shaped nest, rarely up to 9. Throughout most of the breeding range, the Blackpoll Warbler is largely unaffected by habitat degradation due to the remoteness of their nests. ///XObject<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 612 792] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> x��[�O�H����P��]���B�V}m7��hf?$!

This includes boreal forests in Alaska, much of Canada, and some parts of northern New England. Some birds, often with lower body weights, do not make it. Grouse?
