Cornell Lab of Ornithology currently produces these maps. “The detailed information coming from observations submitted by bird watchers around the world is a game changer,” said Amanda Rodewald, the Garvin Professor and co-director of the Center for Avian Population Studies at the Cornell Lab. Estimated for 2018. But across their broad range, Yellow Warblers are one of the most numerous warblers in North America (with an estimated population of 90 million) and their numbers seem stable. What do you get when you combine what bird-watchers observe with what satellites see from space? The live migration maps take data from weather radars, which can detect migrating birds, and package them up into quantified maps: one for each night of migration. Below is a map containing Warbler "final sighting" data from our users. “These new data products show week to week where species occur, and this type of spatial and temporal information helps guide more flexible conservation solutions that can more readily accommodate human and ecological needs.”, “Now, we not only have an idea of where to find a bird, but where that bird is most abundant as well.”. It shows the slow-and-then-sudden invasion of returning Yellow Warblers, day by day, from March 15 to June 15. See real-time analysis maps of intensities of actual nocturnal bird migration, as detected by the US weather surveillance radar network between local sunset to sunrise. They combined human observations for 610 species with NASA satellite imagery of land cover, land use and water, along with nighttime light data from the National Oceanic and Atmospheric Administration. They typically begin reaching the southern border of the U.S. in March and early April. They’re also among the most conspicuous—fairly easy to see as they forage about frenetically in bushes or perch at the tops of shrubs and small trees to sing loud and proud. And their nests are often parasitized by Brown-headed Cowbirds—that is, cowbirds sneak into Yellow Warbler nests and lay their eggs. 2020. eBird Status and Trends, Data Version: 2018; Released: 2020. In fact, studies suggest that a Yellow Warbler’s streaking may be a sign of his behavior—the more streaking, the more aggressive a male acts toward other males. This map depicts the range boundary, defined as the areas where the species is estimated to occur at a rate of 5% or more for at least one week within the pre-breeding migration season. Tom finished by saying that with the colder weather to the … So when can you count on seeing your first Yellow Warbler (or hearing its sweet-sweet-I’m-so-sweet song)? (The data were grouped by state and the patterns should be regarded as approximate.). The Cornell Lab will send you updates about birds, birding, and opportunities to help bird conservation. Citizen-science data can help answer any number of questions about where and when species may benefit most from conservation efforts. We estimate that 405 million birds will take flight tonight across the lower 48, including 50 million birds in the northeast alone. eBird data from 2014-2018. These new animated maps are publicly available for researchers, educators and conservationists to help inform conservation actions. Some of the earliest returnees to look for are Red-winged Blackbirds, Eastern Phoebes, Tree Swallows—and that buttery ball of sunshine in the photo above. This animation is using eBird data to show where a barn swallow may be found any time of the year. They typically begin reaching the southern border of the U.S. in March and early April. Migration: In spring Yellow Warblers depart their wintering grounds in Central America and northern South America. For example, you can see Canada Warblers move from concentrated wintering locations in the Andes in South America to their breeding grounds in the United States and Canada. Kathi Borgmann is communications coordinator for Macaulay Library. https://doi.org/10.2173/ebirdst.2018, Certain products may be unavailable due to insufficient data. . Naturally, it depends on where in North America you live. Tom reported on 10-14 that they have a decent amount of birds around right now. funded by donors like you. The detail and information in the animations is breathtaking.”. Quick Facts About Yellow Warblers. You can listen to its song in our Macaulay Library. Warblers Migration Map. The new eBird animated abundance maps show movements and abundance of birds through the Americas as birds travel to and from their breeding grounds. The common mnemonic is sweet-sweet-sweet-I’m so sweet! Learn more about Yellow Warblers in our online species guide. Backyard bird event counting on citizen scientists, Birding game creates citizen science data where none exists. The maps and animations are made possible through support from the National Science Foundation, Wolf Creek Charitable Foundation, Leon Levy Foundation, NASA, Amazon Web Services and the Institute for Computational Sustainability. By May they’re setting up breeding territories in shrubby thickets and woods—particularly along streams, rivers, and wetlands—across the northern two-thirds of the continent. The rest of the world calls it spring fever, but for birders it’s FOY season. Follow the ducks this season using the most comprehensive waterfowl migration map on the web. Read real-time reports from DU biologists, field editors, expert waterfowlers and more. In the fall, Canada Warblers slowly make their way south through Mexico and Central America before settling in the Andes. Fink, D., T. Auer, A. Johnston, M. Strimas-Mackey, O. Robinson, S. Ligocki, B. Petersen, C. Wood, I. Davies, B. Sullivan, M. Iliff, S. Kelling. During spring migration, the Gulf Coast of Texas, a key stopover and refueling point for Canada Warblers, lights up purple, indicating a large concentration of Canada Warblers. The eBird program at the Cornell Lab of Ornithology just released 500 animated maps spanning the entire Western Hemisphere. Hummingbird, Orioles, Purple Martin Bird, Other Migratory Birds, Warblers, and Butterflies Migration Maps And as more people around the world report which birds they see, the eBird science team will be able to build global models to show the interconnectedness of birdlife and guide bird conservation everywhere. But Benjamin Van Doren (a Cornell undergrad) and Andrew Farnsworth of our BirdCast project delved into the eBird database to make this animated map. These visualizations are striking, but they’re much more than eye-candy. He stated that he hasn’t seen much of a true migration yet to his area yet this fall. Both males and females are bright lemon yellow, though males also have reddish-chestnut streaking on their chest. Learn more. Last Updated November 12, 2020. “Now, we not only have an idea of where to find a bird, but where that bird is most abundant as well. Find out when other migrants are near you: Take a look at our eBird Occurrence Maps; moving range maps for over 50 species including: And check out the cool migratory patterns for these species: Available for everyone, This map depicts the range boundary, defined as the areas where the species is estimated to occur at a rate of 5% or more for at least one week within the pre-breeding migration season. Something spectacular. Population Status: Locally, Yellow Warbler populations can be harmed by the disappearance of their nesting habitat, such as removal of willows along creeks. Check it out—and let us know how closely it matches the date of your first sighting. Yellow Warblers are among the first of the spring warblers to move en masse up the North American continent in spring. Cornell Lab of Ornithology, Ithaca, New York. To create these new visualizations, the eBird science team used five years of observations from 179,297 bird watchers across the Western Hemisphere. Song: Yellow Warblers sing vociferously in spring and early summer, and theirs is one of the easier bird songs to learn. The maps show in fine detail where hundreds of species of migratory birds travel, and how their numbers vary with habitat, geography and time of year. That’s shorthand for “first of year sightings,” and it’s that tantalizing time when the first rock-solid signs of spring start to gain the upper hand over frigid mornings. The BirdCast model is predicting high intensity migration for the night of 14 September 2020. “Building upon more than 750 million observations submitted to eBird provides a whole new way of seeing biodiversity,” said Steve Kelling, co-director of Center for Avian Population Studies at the Cornell Lab. For example, you can see Canada Warblers move from concentrated wintering locations in the Andes in South America to their breeding grounds in the United States and Canada. During spring migration, the Gulf Coast of Texas, a key stopover and refueling point for Canada Warblers, lights up purple, indicating a large concentration of Canada Warblers. eBird is the largest biodiversity citizen science project in the world. This will likely represent one of the largest migration … Migration: In spring Yellow Warblers depart their wintering grounds in Central America and northern South America.
