Protecting Canada’s boreal forest is critical to saving this amazing songbird.”, William V. DeLuca et al. Blackpoll Warbler - Setophaga striata St. Martin - Etang Gulchard (SX) 2011-10-20 Hans Verdaat This time of year it'll be making the journey from far western Alaska all the way across Canada and the Atlantic Ocean to South America. Butler, C.J. For more than fifty years, it has been hypothesized that, during autumn migration, blackpoll warblers depart northeastern North America and undertake a non-stop flight to Puerto Rico, the Lesser Antilles, or northern South America. Blackpoll warblers ( Setophaga striata) that breed in western North America migrate up to 12,400 miles (20,000 km) roundtrip each year, some … Annual blackpoll warbler migration between the northern breeding grounds and A blackpoll warbler in the fall, ... On most late summer and fall nights with heavy migration, the flight direction in the Northeast is northeast to southwest, roughly parallel to the coastline. The distance from southern Newfoundland over the western North Atlantic Ocean to northern South America is only about 200 km longer than that from Sydney, Nova Scotia, so a nonstop flight from Newfoundland is well within the capabilities of the Blackpoll Warbler. Earth Matters: Tiny blackpoll warblers are champions of long-distance flight A blackpoll warbler in the fall, fattening for its flight to South America. This long-distance athlete weighs less than half an ounce yet makes the longest overwater journey of any songbird—nearly 1,800 miles nonstop over the Atlantic Ocean to its wintering grounds. Doppler Radar 16 Geolocators Satellite Tracking Radio Telemetry The blackpoll warbler, a songbird that weighs no more than an AA battery, flies nonstop across the Atlantic Ocean during its southerly fall migration, covering more than 1,500 miles (2,400 kilometers) in two or three days, a new study confirms. Berttam G. Mnrrar, Jr. BLACKPOLL WARBLER MIGRATION 72- 60- a w m 5 2 z 361 24- 12- 01 127 GRAMS FIG. This long-distance athlete weighs less than half an ounce yet makes the longest overwater journey of any songbird—nearly 1,800 miles nonstop over the Atlantic Ocean to its wintering grounds. The Blackpoll, like the Black-and-white Warbler is a Neotropical migrant and both are most often observed during the spring migration. The geo-locators tracked the birds’ flight path, but, because of their small size, they were not able to transmit the data remotely. “When we accessed the locators, we saw the blackpolls’ journey was indeed directly over the Atlantic. A new study, published in the journal Ecology, confirms the epic migration journey that ornithologists had long suspected but not yet proved. Frequency distribution of weights of 352 Blackpoll Warblers captured at Island 42 Fall migration of the Blackpoll Warbler S. R. Morris, K. M. Covino, J. D. Jacobs, and P. D. Taylor following keys in the North American Bird Banding Manual (U.S. Taipan. “We had long believed that blackpoll warblers followed the great circle route. “As a conservation scientist, what strikes me most is that in a single year a blackpoll warbler has to navigate 12,400 miles across land and ocean, facing risks of cat predation, storms and collisions with buildings and vehicles, all while trying to find islands of habitat to rest and refuel in our human-dominated landscapes,” said study co-author Dr. Hilary Cooke, a conservation scientist with Wildlife Conservation Society Canada. Magnolia Warbler Summer; Breeding Migration Winter; Non-breeding *modified from State of North America’s Birds 2016. BLACKPOLL WARBLERS ON ABACO: UNCOMMON TRANSIENTS. 1. Blackpoll Warbler - Setophaga striata. Blackpoll warblers breed across the North American boreal forest from Alaska to Newfoundland and in isolated montane fir forests at the southern periphery of their range in northeastern United States (Figure 2; DeLuca et al., 2013). The coast will, however, always have a concentrating effect, resulting in an increased number of records from that-area. 8. 2003. “To prepare for the flight, the birds build up their fat stores. The Blackpoll Warbler is a tiny bird with an annual migration route of some 12,000 miles. “For small songbirds, we are only just now beginning to understand the migratory routes that connect temperate breeding grounds to tropical wintering areas,” Mr DeLuca said. They weigh 0.4 – 0.5 oz (12–13 g). For the study, Dr. Norris and co-authors tracked birds outfitted with tiny geolocators, weighing 0.5 g and with a 12-month battery life, from four boreal forest sites: Churchill, Manitoba; Whitehorse, Yukon Territory; Denali National Park and Nome, both in Alaska. Biology Letters, published online April 01, 2015; doi: 10.1098/rsbl.2014.1045, © 2011-2020. 2016), which combined with the earlier spring migration provides the possibility of a longer breeding season in this species. All Rights Reserved. Blackpoll Warblers (Setophaga striata) breed across Canada and the northern United States and fly across the Atlantic Ocean to South America in fall. The scientists also placed colored plastic bands on the birds to identify them when they returned. The species primarily breeds across Alaska and north-central Canada. Fall migration for Blackpoll Warblers has been occurring later at a rate of approximately 1 day per decade (Morris et al. Few of the birds have ever been found in the central or western States during fall migration,” Dr. Norris said. The warbler's longest nonstop flight was recorded as 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. Share with: Link: Copy link. The disproportionate effect of global warming on the arrival dates of short-distance migratory birds in North America. McNair, D.B., and W. Post. Sci-News.com. Blackpoll Warbler 14 Ruby-throated Hummingbird Arctic Tern. “It’s amazing. “We’re really excited to report that this is one of the longest nonstop overwater flights ever recorded for a songbird, and finally confirms what has long been believed to be one of the most extraordinary migratory feats on the planet.”, William V. DeLuca et al. The blackpoll warbler (Setophaga striata). Blackpoll Warbler: Breeds from inland Alaska and northern Canada south across the central provinces east to northern New England. DeLuca et al deployed tiny geolocation devices with a 12-month battery life on male blackpoll warblers at four locations: Churchill, Manitoba; Whitehorse, Yukon Territory; Denali National Park and Nome, both in Alaska. Abstract. The blackpoll warbler (Setophaga striata). The well-noted 2,150 autumn migration distance some New England Blackpoll partake in the autumn as trans-ocean migrants is a breathtaking marvel. “Population numbers have fallen in recent years, perhaps caused by habitat loss and declines in insect prey related to climate change.”, “To understand what’s causing the decline, we need to know their full annual cycle.”. A bird weighing a couple of loonies travels from the western edge of North America all the way to the Amazon basin — and, in between, traverses the Atlantic Ocean,” Dr. Norris said. Preferred breeding habitat is coniferous forests; during migration found … Apex Predator. 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. On some nights, though, radar shows many birds headed south, ... most go the distance successfully. However, the Black-and-white is abundant during migration and the Blackpoll is uncommon to rare in any given year. Which is to say, the species is classified as an uncommon transient in its migration, and as such it is rarely seen on Abaco. The 0.5-g devices sat on the backs of the birds and were attached using leg loop harnesses, much like a person would wear a backpack. They covered between 1,400 miles (2,250 km) and 2,113 miles (3,400 km) for that transoceanic hop. For more than 50 years however, it has been proposed that they fly in a direct, non-stop, path over the Atlantic back to South America. Autumn migration route of blackpoll warblers: evidence from southeastern North America. “We waited for them to return in the spring and then searched the forest to find the blackpolls with geo-locators,” Mr DeLuca explained. “In comparison, the boreal region of northern Canada provides safe and high-quality breeding habitat for this declining species. Smaller numbers breed in southeastern Canada, and isolated breeding populations exist in the mountains of New England and New York. The Blackpoll Warbler 1993. Share. 9. 0000004457 00000 n "The Blackpoll Warbler is only about four inches long. Sci-News.com. Journal of Field Ornithology 64:417-425. The ornithologists found that in some cases, the birds flew more than 2,500 km, non-stop, to reach their destinations. Image credit: Simon Pierre Barrette / CC BY-SA 3.0. Blackpoll warblers (Setophaga striata) that breed in western North America migrate up to 12,400 miles (20,000 km) roundtrip each year, some crossing the entire North American continent before making a nonstop trans-ocean flight of up to four days to South America. There, the birds spent almost a month fattening up to double their body weight before a non-stop, 2.5-day flight across open water to overwintering grounds in northern Colombia, Venezuela and Brazil.
