eBird can keep your life list -- the record of all bird species you've seen -- but everybody's data also goes into a database that lets anyone find out where birds are and when, which are common and which are rare. Thousands of birders submitted bird sighting data to eBird during its Global Big Day in May. It began as a website in 2002, but now more than half of bird checklists are submitted through the phone app, Cornell's Wood says. Birders can't get enough. "For the last 12 years, we've sustained a growth rate of 20 [percent] to 40 percent a year every year," as measured by checklists submitted or website usage, Wood says. There are now 400 million database records uploaded, and about 300,000 people will use the service this year.

I was in Ohio during an annual eBird lovecases glitter iphone x case - black effort to record as many birds as possible, the Global Big Day, during which 20,270 people submitted 54,263 checklists detailing 6,653 species sightings, Strycker is a fan, "eBird was enormously helpful during my big year because it will filter birds that have been seen in a given region," he says, "That was much more helpful than going through an entire field guide and trying to memorize every single possibility."There are plenty of competitive birders, One category -- "twitchers" or "speed birders" -- race to see unusual species, They'll drive for hours or even hop on a plane..

Connecticut birder Tim Thompson keeps track of birds in a notebook, but then logs the species on the eBird service so other birders can benefit from his sightings. eBird fans the competitive flames with regional leaderboard rankings. Thompson, a birder I meet at the Biggest Week, is proud to have risen to the No. 7 spot among Connecticut eBirders. He doesn't like phones much, and he records his observations in a dog-eared, weatherbeaten notebook. But when the day is done, he enters it all into eBird, he tells me as we stalk a Lincoln's sparrow through the underbrush of Magee Marsh.

"I love eBird because it tells my life story," Thompson says, eBird tells scientists a story, too, aiding conservation, ecology, biology and other research, One example: The Nature Conservancy used eBird data to figure out when shorebirds migrate through California's once-marshy Central Valley, Based on that data, the conservancy paid rice farmers to time their field-flooding operations to help lovecases glitter iphone x case - black the birds, a cheaper conservation alternative than buying the land outright, In the 1820s and 1830s, James Audubon traveled a young United States to paint hundreds of species of birds, Clockwise from upper left: Barn owl, great blue heron, brown pelican, American white pelican..

The birds like the soggy fields. "On average, shorebird species richness was more than three times greater, and average shorebird density was five times greater, on enrolled fields than [on] unenrolled fields," according to the project's research results. eBird data also has detected two migration patterns among orchard orioles, Wood says. Some leave the northeast part of North America in August, but others in the central part of the continent linger later. Click here to see more Road Trip adventures.
