Breeding: The occurrence of Bay-breasted Warblers is closely correlated with the distribution of spruce and balsam fir forestsBay-breasted Warbler breeding range map in Canada and the U.S. Ninety percent of range lies in Canadian boreal forest, extending west to British Columbia but with the bulk of the breeding population east of Ontario. The remaining 10% breeds in the northern U.S., primarily in Maine. Elsewhere in the U.S., it is considered an uncommon to rare breeder. More

A neotropical migrant, the Bay-breasted Warbler lives in boreal coniferous forests in central and eastern Canada and winters in Panama and northern South America. This species' numbers increase and decrease in correspondence with spruce-budworm outbreaks; pesticides used to control the spruce-budworm may be affecting this bird's overall population. Habitat destruction including tropical deforestation is another concern. Identification A 5. More

They can be found in numerous countries around the world, particularly in the Caribbean, North America and Central America. It has also been spotted in the United Kingdom and Greenland. The population of this bird has not decreased in the last ten years. Consequently, the Bay-breasted Warbler has a rating of Least Concern. More

Bay-breasted Warbler heads for its wintering grounds from Costa Rica to the northern part of South America. When the male arrives he will defend his territory by singing, however the territories will become constricted when food is abundant as is the case during spruce budworm outbreaks. The clutch consists of 4 to 5 white or off-white eggs marked with brown or black at the larger end. The number of eggs may increase during spruce budworm outbreaks. More

The bay-breasted warbler moves through the trees, hopping from branch to branch, feeding on insects. Habitat and conservation: Bay-breasted warblers spend summers in coniferous forests of the northern U.S. and into Canada. Panama, Venezuela and Colombia are their winter range, where they feed in flocks along woodland borders. More

Bay-breasted warblers are found in woodlands and conifer stands. Diet They eat arthropods and in the winter they eat fruit. Range They summer in Canada and migrate through the eastern part of the United States down to the Panama and northern South America. Other Useful Information The populations of the bay-breasted warbler fluctuate greatly and are highly dependent on spruce budworms. More

The Bay-breasted Warbler breeds in the boreal coniferous forests in central and eastern Canada and winters in Central America and northern South America. Its populations rise and fall dramatically with outbreaks of spruce-budworm, which form part of the natural cycle in maturing balsam firs. During one outbreak of spruce budworm in New England, population increases up to 300% occurred due to greater clutch sizes and immigration of conspecifics into the area. Typically, population crashes follow outbreak years. More
