They often build a new nest directly on top of the parasitized one, sometimes resulting in nests with up to six tiers. We may even be experiencing a decrease in birds because the effects of global warming changes where birds are willing to migrate (Hitch). In areas with lots of deciduous trees, yes. Incubation usually takes 11 days, sometimes up to 14. Because of their well-built open-cup tree nests, parasitic cowbirds will often lay eggs in yellow warbler nests. A Popular Handbook of Birds of the United States and Canada. Accessed Stoddardi has a yellow lore and they actually favor a smaller habitats and are usually non-migratory (Mckay 2007).

Territorial level depends on the area (Emlen). (1997). ");  Some local decline in numbers has been found in areas, mainly due to habitat destruction and pollution. (On-line). They avoid ash, hickory and maple trees. “First time observer effects in the North American breeding bird survey.” The Auk (1996): 823-829. (2019). Small insect larvae and caterpillars are preferred foods. Most species of wood-warblers are long distance migrants to Central and South America. 23 Sept. 2016. If a breeding attempt fails, either parent will usually try to raise a second brood. The races in this group vary in the extent and hue of the hood, overlapping extensively with the golden warbler group in this character. There are also vagrant populations in Denmark, Greenland, the UK and Portugal as well. Link.

The bright, sweet song of the Yellow Warbler is a familiar sound in streamside willows and woodland edges.
