AND A QUIZ! Identify the other bird singing in the recording. His song is not normally heard in southwestern PA in the summer. The mourning dove lives year-round from Maine to Mexico, from Canada to Cuba. The other bird will give you a hint on the location of the recording.

UPDATE: Chuck Tague wrote in the comments: “The difference is social structure. Ducks are seasonally monogamous and form a bond that lasts only through courtship and the initiation of incubation. The male takes no role in raising the young. Geese and swans form strong bonds that last for many seasons (or life) and maintain family units through migration. Whistling ducks are closer to geese than ducks.”
See the other comments, too! Lots of great information.
Every time I look at the silhouettes, I find myself trying to identify the birds. There are 26 individuals and 3 flocks in the image. How many of the silhouettes can you identify?
Tips: I’ve numbered the individuals and marked the flocks with letters below. Assume each flock is made up of the same species. Some of the 26 individuals are repeats. If you can’t identify the exact species, name the bird by group, as in “gull.”
Post your answers in the comments. Good luck!

Can you recognize the name of a bird in a language you’ve never heard?
Last weekend I found a 2009 New York Times science quiz where you can test this skill.
The quiz is a sample from a study conducted by anthropologist Brent Berlin at the University of Georgia. In it he showed that human names for the natural world usually incorporate qualities of the organisms, so we can tell the difference between a bird name and a fish name even if we’ve never heard the language.
The questions in the study, and the quiz, present pairs of bird and fish names in a very foreign language: the Huambisa language of Peru. Brent Berlin pronounces the words in audio clips.
The original study participants correctly guessed the bird name 58% of the time. My hunch is that birders will score higher than that.
I did amazingly well, correctly choosing 9 out of 10 bird names. This photo shows the bird whose name I missed.

When you play today’s “quiz” you’ll be teaching a computer how to think.
The Cornell Lab of Ornithology is building a new interactive bird identification tool and they need your help. In yesterday’s eNewsletter they wrote:
To help you identify birds online, the Cornell Lab’s web team is building a new tool called “Merlin.” Merlin will use artificial intelligence to ask questions and provide suggestions to help you identify what you saw. First, though, Merlin needs to know how people observe and describe birds. Help populate Merlin’s “brain” by trying Mark My Bird, an online activity that asks 18 questions about a species. Play as often as you like to help us build Merlin faster!
Mark My Bird looks like a quiz but it’s actually gathering data for Merlin’s brain. It will show you a photo of a mystery bird but don’t worry, it’s going to identify that bird for you. All you have to do is choose the bird’s group (or say Not Sure), then click on the bird’s body parts and checkmark the colors and patterns you see.
I tried it myself and it’s pretty cool. You can use it to quiz your own bird skills or identify the mystery bird.
