The image is from https://www.ontario.ca/page/cerulean-warbler. Note that the Cerulean Warbler is a Species at Risk in Ontario – Status Threatened. “In Ontario and the United States, the main threat to this warbler is habitat loss from degrading and fragmenting forests, since it requires relatively large tracts of forest.”
