Research: Radar Aeroecology

TL;DR: Special issue on Radar Aeroecology  As you know, one of the main methods we use to study birds here at BirdCast is radar. Radar has been used to study animal movements for a long time, but recent advances has greatly increased its use and lead to a new wave of research and applications of […]


Recent Press, 2011-2019, for BirdCast and its team

Since its beginnings, BirdCast has been fortunate to receive media attention from a diverse array of outlets. We’ve assembled some of these below in this post to keep you all updated on the outreach and education. Some of the links are more directly related to our work with radar and aeroecology, others more closely to […]


Research: Nocturnal flight-calling behaviour predicts vulnerability to artificial light in migratory birds

ANN ARBOR—Birds that produce faint chirps called flight calls during nighttime migration collide with illuminated buildings much more often than closely related species that don’t produce such calls, according to a new analysis of a 40-year record of thousands of building collisions in the Midwest. The new analysis of more than 70,000 nighttime songbird collisions in […]


Research: Study Names Top Cities Emitting Light that Endangers Migratory Birds

Chicago, Houston, and Dallas top the list Ithaca, NY—An estimated 600 million birds die from building collisions every year in the United States. Scientists at the Cornell Lab of Ornithology have published new research highlighting artificial light at night as a contributing factor. They’ve ranked metropolitan areas where, due to a combination of light pollution and […]


Research: Study Finds 2 Billion Birds Migrate Over Gulf Coast

Data from radar & bird watchers reveal spring migration details Ithaca, NY— A new study combining data from citizen scientists and weather radar stations is providing detailed insights into spring bird migration along the Gulf of Mexico and how these journeys may be affected by climate change. Findings on the timing, location, and intensity of these bird movements are published […]


Research: How Will the Winds of Climate Change Affect Migratory Birds?

New study finds both positive and negative impacts possible Ithaca, NY—Under future climate scenarios, changing winds may make it harder for North American birds to migrate southward in the autumn, but make it easier for them to come back north in the spring. Researchers from the Cornell Lab of Ornithology came to this conclusion using […]


Research: What Did Birds & Insects Do During the 2017 Solar Eclipse?

Radar study finds less activity during the event Ithaca, NY—In August of 2017, millions peered through protective eyewear at the solar eclipse—the first total eclipse visible in the continental United States in nearly 40 years. During the event, researchers from the Cornell Lab of Ornithology and the University of Oxford watched radar to observe the […]


Research: Seasonal abundance and survival of North America’s migratory avifauna determined by weather radar.

4 Billion Birds Will Fly Through American Airspace This Fall By Carley Eschliman From the Autumn 2018 issue of Living Bird magazine. Subscribe now. Fall migration will bring 4 billion birds into the skies over the United States. That’s not a guess—it’s hard data, gleaned from the first-ever national bird count using weather radar. Cornell […]


Research: Creating a Continental Bird Migration Forecast

Researchers predict the movements of millions of birds across the United States Ithaca, N.Y. & Oxford, U.K.—September is the peak of autumn bird migration, and billions of birds are winging their way south in dramatic pulses. A new study published in the journal Science reports that scientists can now reliably predict these waves of bird migration […]


Weather surveillance radar: beyond meteorology

Doppler weather radar data—like those shown in the animation above and often featured in weather broadcasts—can tell us much more than how much rain will fall on your weekend cookout. Here at BirdCast, we turn weather radar data into information on the numbers and flight directions of birds aloft in order to expand the understanding […]
