This is ALL THINGS CONSIDERED from NPR News. I'm Melissa Block.
AUDIE CORNISH, HOST:
I'm Audie Cornish. And it's time now for All Tech Considered.
(SOUNDBITE OF THEME MUSIC)
CORNISH: A Smartphone can help us find just about anything these days - a restaurant, a movie theater, even a date to share your popcorn. If however, the object of your affection is a Cape May Warbler and your idea of an afternoon out includes binoculars, don't worry.
As NPR's Margot Adler reports, even bird watching is getting a hi-tech update.
MARGOT ADLER, BYLINE: I'm standing in the Manhattan office of Andrew Farnsworth, a research associate at Cornell University's Ornithology lab. He's forecasting bird migration. Birdcast is a project funded by the National Science Foundation.
ANDREW FARNSWORTH: Take meteorological data and e-Bird data and acoustic data, so flight calls of birds that are migrating at night and radar data. And combine all of those things to make forecasts across the entire continental U.S. of when birds are going to appear where.
ADLER: Eventually it will be a website and an app, but you can see the posts now on Cornell's e-Bird site. So I say, Andrew, I'm going birding in Central Park on Saturday, its spring migration. Tell me what you know. He tells me the winds will be really favorable.
FARNSWORTH: Winds are forecast to be southerly, there is not forecast to be any rain.
ADLER: Two days later, I am in the park with Starr Saphir, an avid birder for more than six decades.
STARR SAPHIR: So there are at least three yellow rumps right in that area.
ADLER: She came in early in the morning.
SAPHIR: We knew that this would be an absolutely great day, I had a common raven which is an unusual bird in Manhattan. And it just heated up from there.
ADLER: But here's the difference. Twenty years ago, if you saw a good bird, you might tell other people in the park, or call someone that night. Now between cell phone calls, text messages, e-mail you can be there in a minute or two.
(SOUNDBITE OF A RINGTONE)
SAPHIR: Hello. OK, bye. Male Cape May Warbler exactly where we're going.
ADLER: Soon our group is walking quickly toward the Cape May Warbler. Earlier we were led to a Prothonatory Warbler. At one point, we see 30 birders in one spot - the news of the Prothonatory has spread swiftly.
An easy way to find birds is to know their calls. There have long been recordings of bird songs. What's different now, says Farnsworth is the app is right on your phone. Thousands of bird calls right in your pocket.
FARNSWORTH: You can bring it into the field and compare it with what you're actually hearing and seeing.
(SOUNDBITE OF A SCARLET TANAGER)
ADLER: So my Audubon app, for example, has seven different sounds for a Scarlet Tanager. They're on my phone when I go into the park to search for it. And in the future, you'll be able to do the reverse: hear a bird song and identify it with an app, just like people identify music with an app like Shazam.
Mark Berres is a professor at the University of Wisconsin at Madison, is working on WeBird. But identifying bird calls is harder than popular songs.
MARK BERRES: When I turned it on to the bird songs, oh, it just failed miserably.
ADLER: But a year of work later and he says the app will be ready next spring.
You can find bar charts on Cornell's e-Bird Web site that will tell you when a species migrates to your area, what dates it will arrive. Chris Wood runs the eBird project at Cornell's Ornithology lab. Technology, says Wood...
CHRIS WOOD: It's lowered the barriers to entry and made it easier for people to quickly get the information that they have when they see a bird.
ADLER: So, for example, when he started birding in Colorado, he was sure that he had a tricolored blackbird in his backyard because it looked a lot like the bird in the book. It took him three years to realize...
WOOD: There are no records of tricolored black birds anywhere from outside California and the West Coast.
ADLER: Now that process of finding out you were wrong might take an hour.
Andrew Farnsworth's fantasy is in the future the Weather Channel will give you its daily bird report. And models will be so sophisticated, conservationists can tell a city turn off your lights tonight - there's a huge wave of birds coming in.
Starr Saphir - who doesn't have a computer - says the downside to all this technology is an inexpensive hobby is now out of reach for many.
SAPHIR: You have to have thousands of dollars worth of equipment.
ADLER: Cameras, apps, computers. Saphir makes do with very good binoculars and, yes, a cell phone.
SAPHIR: OK, I'll be right there. Bye.
ADLER: And off we go. Some argue the pastime is no longer as pastoral.
