Overall, Blackpoll Warbler appears to have been declining in numbers for many decades. Canadian Conservation Status: N/A Male in breeding plumage with black and white head, grey upperparts with black streaks, white underparts with black streaks; dark wings with two white wing bars; dark tail with white spots. Create a bird friendly backyard to provide foraging habitat for migrating Blackpoll Warblers and other birds. It has one of the highest pitched songs of any bird and the longest migration of any North American warbler, including almost unimaginably long, nonstop, transoceanic flights. 2013). Vista Grande Canal, Lake Merced, San Francisco, California. If you are a researcher and would like to contribute data to Audubon's Migratory Bird Initiative, please fill out this Data Sharing Agreement. They are a common migrant through much of North America. Using the latest science, we will protect migratory birds during breeding season, winter and their migrations in between, conserving habitat and addressing threats they encounter year-round. It winters in northern South America, and has occurred as a vagrant to Europe. Their breeding habitats are coniferous woodlands, especially those in which spruce trees grow. doi: 10.1002/ecy.2651. By a vote of 43-3, the City Council approved that all new construction must use materials that prevent avian fatalities. This species has one of the longest non-stop migration of any song bird. Beck, D. Lepage, and A.R. New research confirms that this songbird’s migration is one of the longest out there—and it may be in danger. You can also spot Blackpoll Warblers during fall migration, but they take a different route than in spring and are unlikely to be seen south of North Carolina. Nevertheless, the NABBS records suggest an extreme decline of nearly 5% per year from 1966–2015, resulting in a cumulative decline of 92% during that time period. Many species of birds, like the Boreal breeding Blackpoll Warblers, return to the Amazon Forest weighing less than half an ounce, making the longest overwater voyage of any songbird. Those birds tend to have longer wings than those nesting in eastern Canada. Nest height ranges from 0.5–30 feet above the ground. The Blackpoll Warbler is an abundant and widespread species of northern Canada, breeding only in the boreal ecozone. U.S. Conservation Status: N/A 2015. By sensing the light level for almost every minute of the day, for every day of the year, you can see how these geolocators can give you general location estimates as a bird migrates throughout the hemisphere.”. They tend to forage at eye level and above, picking insects off the branches of evergreen and deciduous trees and shrubs. The remote nature of its breeding range would also appear to make logging there unlikely to be a significant threat too (DeLuca et al. The sharply marked Blackpoll Warbler is nature’s hearing test, with a high-pitched, almost inaudible song that floats through the boreal forests of Canada. “It was the first research project of its kind for this species—it was the first year that geolocators had become small enough,” says DeLuca. Bald Eagle. However, a significant data deficiency due to the remoteness of its breeding range makes the rate of decline is difficult to determine: Estimates range from 20.9% over three generations (10.5 years) (North American Breeding Bird Survey; Sauer et al. “It’s the same concept that was used for centuries for people to navigate around the globe,” says Bill DeLuca, a migration ecologist for Audubon’s Migratory Bird Initiative. When the flight distance per body mass was compared to other birds, only the ruby-throated hummingbird might travel more kilometres per gram (estimated around 210–280 km/g vs. 233 km/g for blackpolls).[11]. Although mostly monogamous some males breed with more than one female. Version 2.07.2017. (2014). DeLuca had been studying Blackpoll Warblers for years, and had questions about their overwintering ecology. Clockwise from upper left: MacGillivray's warbler, blackpoll warbler, Louisiana waterthrush, and bay-breasted warbler. Non-breeding birds of this species have greenish heads, dark-streaked greenish upperparts and yellowish breasts, with the yellow extending to the belly in young birds. The genus name Setophaga is from Ancient Greek ses, "moth", and phagos, "eating", and the specific striata means "striped".[2]. In the spring, males arrive north before females and almost immediately start setting up their territories. Back to top. “Since then we’ve been able to track even smaller birds,” says DeLuca. Come fall, they fly South to the Greater Antilles and the Northeastern coasts of South America in a non-stop long-distance migration over open water, averaging 2500 km, one of the longest distance non-stop overwater flights ever recorded for a migratory songbird. 2019. Link (2017). Audubon protects birds and the places they need, today and tomorrow. 2013). Bird Studies Canada, Environment Canada, Ontario Field Ornithologists, Ontario Ministry of Natural Resources, and Ontario Nature, Toronto, xxii + 706 pp. Despite their affinity for evergreen trees on the breeding grounds they tend to forage in deciduous trees and shrubs during migration.
