eBird Status and Trends products are updated annually with millions of new observations submitted by eBirders to provide the most up-to-date information on the status and trends of bird populations. This year, the team released new tools, added regional trends summaries, and made Trends data available for download.
Every year the eBird Status and Trends project updates the maps with millions of new observations submitted by eBirders. This year, the team modeled relative abundance for 868 additional species across the globe using data from 464,542 eBirders—bringing the total number of species with visualizations to 2,068.
A new study helps reveal why tropical mountain birds occupy such narrow elevation ranges, a mystery that has puzzled scientists for centuries. While many assumed temperature was responsible for these limited distributions, the latest research suggests competition from other species plays a bigger role in shaping bird ranges.
Many birds migrate at night. The cool and calm evening skies make migrating at night a little smoother for birds, but nighttime lights can make their journey more treacherous.
Researchers compared online eBird observations from the United States and Canada from before and during the pandemic. According to this new study, eighty percent of the bird species examined were reported in greater numbers in human-altered habitats during pandemic lockdowns.
Public participation in scientific research through citizen-science projects has skyrocketed in the past 10 years. Citizen scientists have been donating billions of dollars’ worth of their time collecting information on everything from birds, bees, butterflies, and more resulting in a treasure trove of data helping scientists better understand plant, animal, and insect populations.
A new study using sightings reported to eBird found that many migratory birds time movement to match “green-up” or emergence of leaves, as they travel north and south. Frank La Sorte, a research associate at the Cornell Lab of Ornithology and Catherine Graham, a researcher at the Swiss Federal Research Institute in Switzerland, found that […]
Protected areas are a key strategy for preserving biodiversity yet evaluating if protected areas actually preserve biodiversity is challenging often due to lack of data. In a recent study published in Nature Communication, a team of international researchers led by Victor Cazalis at the University of Montpellier set out to investigate whether protected areas were […]
During extremely hot days you might retreat to an air conditioned room, visit the local swimming hole, or take a trip to cooler climates. But how do birds handle the heat?
Urban parks and other green spaces are a welcome refuge from our busy lives, especially now. And research suggests that being outside in nature no matter how wild provides important benefits to our mental and physical well-being. Green spaces also provide important places for birds to take refuge, but not all green spaces are the […]
