Secrets hidden in more than 300,000 index cards with hand-written information about nesting birds are gradually being revealed. The Cornell Lab of Ornithology is partnering with Zooniverse, an online people-powered research tool, to digitize this valuable collection and create the largest database of nesting bird information in the U.S. This new effort is called “Nest Quest Go!” » Continue Reading.

After pairing up and raising chicks, males and females of some bird species spend their winter break apart. At the end of their journey to Central or South America, you might find mostly males in one habitat, and females in another.
Yet conservation strategies have typically overlooked the habitats needed by females, putting already-declining species in even more peril, according to a new study in the journal Biological Conservation. » Continue Reading.
In light of recent news about the net loss of nearly three billion birds in the U.S. and Canada since 1970, advocates say it’s more vital than ever that citizen scientists monitor their own backyard birds.
Participants in Project FeederWatch at the Cornell Lab of Ornithology have been doing this for decades. Reports from participants are building the kind of long-term database needed to detect shifts in the number and distribution of birds facing challenges from climate change, habitat loss, and disease. » Continue Reading.
A study published in the journal Science reveals that since 1970, bird populations in the United States and Canada have declined by 29 percent, or almost 3 billion birds, signaling what has been considered a widespread ecological crisis.
The results show tremendous losses across diverse groups of birds and habitats — from iconic songbirds such as meadowlarks to long-distance migrants such as swallows, and backyard birds such as sparrows. More research is needed to pinpoint primary causes for declines in individual species. » Continue Reading.
During the late 19th and early 20th centuries, the use of feathers in women’s hats was all the rage.
To meet fashion industry demand for their elegant plumage, several North American bird species (e.g. egrets, herons) were hunted to near-extinction. » Continue Reading.
Cross-referencing a decade of Google searches and citizen science observations, researchers say they have identified which of 621 North American bird species are currently the most popular and which characteristics of species drive human interest. » Continue Reading.
In the first global test of the idea, scientists have found evidence that some woodpeckers can evolve to look like another species of woodpecker in the same neighborhood. The researchers say that this “plumage mimicry” isn’t a fluke – it happens among pairs of distantly related woodpeckers all over the world. » Continue Reading.
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.
The research was published in the journal Frontiers in Ecology and the Environment. It combines satellite data showing light pollution levels with weather radar measuring bird migration density. » Continue Reading.
Using data on 77 North American migratory bird species from the eBird citizen-science program, scientists at the Cornell Lab of Ornithology say that, in as little as four decades, it may be very difficult to predict how climate change will affect migratory bird populations and the ecosystems they inhabit.
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 according to researchers from the Cornell Lab of Ornithology.
They came to this conclusion using data from 143 weather radar stations to estimate the altitude, density, and direction birds took during spring and autumn migrations over several years. They also extracted wind data from 28 different climate change projections in the most recent report from the Intergovernmental Panel on Climate Change (IPCC). Their findings were published in the journal Global Change Biology. » Continue Reading.
Most songbirds migrate in darkness, usually when weather conditions are favorable. Tailwinds can produce massive migratory movements. Rain can shut down flights entirely.
“Knowing when and where a large pulse of migrants will pass through is useful for conservation purposes,” says Benjamin Van Doren, a former Cornell undergraduate and now Ph.D. candidate at the University of Oxford. “Our forecasts could prompt temporary shutdowns of wind turbines or large sources of light pollution along the migration route. Both actions could significantly reduce bird mortality.” » Continue Reading.
The following comes from the Cornell Lab of Ornithology.
When male animals compete over mates, it’s often a showy affair: think of elk tangling antlers or tom turkeys strutting and gobbling. But for a Costa Rican hummingbird, it seems mental prowess holds the edge over mere physical flamboyance.
New experiments show that dominant male Long-billed Hermits have better spatial memories and sing more consistent songs than less successful males, according to research published this month in the journal Scientific Reports. The benefit of a good spatial memory even outweighs the advantages of bigger body size and extra flight power. » Continue Reading.
The Cornell Lab of Ornithology and Alaska Organic Fertilizer company are offering grants to support school gardens in the United States, excluding it’s territories.
BirdSleuth, Cornell Lab’s K-12 education program, will distribute $25,000 in grants to 20 schools that create or revitalize a garden that supports local wildlife, healthy living, environmental education, and Science, Technology, Engineering, and Math (STEM) learning. Grants range from $500 to $2,000. » Continue Reading.
The third annual Global Big Day takes place on May 13, 2017. The term traditionally applies to any effort to identify as many bird species as possible in a single day. Bird watchers around the world are invited to watch and count birds for any length of time on that day and enter their observations online at eBird.org.
“The past two Global Big Days have set back-to-back world records for the most bird species seen in a single day,” says Chris Wood at the Cornell Lab. “During last year’s Global Big Day bird watchers from more than 150 countries tallied more than 60 percent of the world’s bird species.” » Continue Reading.
Participants from more than 100 countries submitted a record 147, 265,000 bird checklists for the annual Great Backyard Bird Count in February and broke the previous count record for the number of species identified. The 5,090 species reported represents nearly half the possible bird species in the world.
The four-day count marked the 18th year for the event which is a joint project of the Cornell Lab of Ornithology and the National Audubon Society with partner Bird Studies Canada. » Continue Reading.
