PERHAPS NO BIRDS are more familiar than crows and ravens—but which is which in these similar-looking members of the genus Corvus? And who’s smarter? Ellen Blackstone of the popular BirdNote public-radio show is our guide again as we look skyward in this latest installment in our collaborative series. And watch out, there’s a crow-or-raven quiz at the end of this one (which is why I’m not telling you who’s who in the photos along the way).
“Out of the 810 species of North American birds, only crows and ravens are completely black,” says Ellen. “But they have much more in common than color. Along with their cousins, the magpies and jays, they’re among the smartest birds on the planet.”
In the Q&A that follows, Ellen’s answers contain green links to audio files from BirdNote’s archive that you won’t want to miss. A recap of earlier stories in our series is at the bottom of the page, along with information on how to get BirdNote daily (and the quiz answers–no peeking!).
crow-and-raven q&a, and a quiz!
Q. So who’s smarter, Ellen? Crow or raven?
A. It’s hard to say. Crows make tools, play games, and outwit other species in search of food. Check out this story about a crow fooling a young glaucous-winged gull on the beach.
A rook, a close cousin to the American crow, may have been the culprit in setting the roof of Shakespeare’s wife Anne Hathaway’s cottage on fire–when all he wanted was to smoke out some parasites under his wings, with a smoldering cigarette. That story.
A New Caledonian crow named Betty is famous for her tool-making skills and even turned up on an official postage stamp.
A researcher of crows discovered that the birds can recognize individual faces–and remember a person for his action–for better and for worse. (Note

“Like the week in Lake Wobegon, it’s been mostly quiet,” says Ellen. “For the most part, the birds have stopped singing.” Turning their attention away from establishing territories, finding mates and having families—what the songs were mostly about—they’ve shifted focus. “Some birds even lose the ability to sing after the breeding season is over,” she adds (learn more about that in this BirdNote show and transcript).In the Q&A that follows, Ellen’s answers contain green links to audio files from BirdNote’s archive that you won’t want to miss.

So what are the birds doing as we enter midsummer?A. Many birds–wrens, robins, and others–may raise more than one brood in a breeding season. Depending on what part of the country you call h
Yes, said my friend Ellen Blackstone of the BirdNote public-radio program, who has been the tour guide for our ongoing series of bird stories here on the blog. (Browse all past installments.)The part of the bird’s brain that’s used for singing shrinks to lighten the bird’s body mass in the offseason, she explained (and here’s the link to hear more on that). In fall and winter, there is no mating ritual; no need to stake out a territory.Many birds can still s
Even the genus of the cowbird’s Latin name, Molothrus ater, probably deriving from the Greek molobros for “greedy fellow,” implies a bad reputation. Older sources say it also means vagabond, tramp or even parasite, and cowbirds are brood parasites—that is, laying their eggs in another species’ nest and not providing parental care. (Those are heavily speckled cowbird eggs in a house finch nest up top.)That we put our human values on cowbirds for leaving their children behind reminded me of something from a class on bird behavior:With that in mind, I confessed to BirdNote consulting scientist Dennis Paulson (also an expert on dragonflies, remember?) that I actually like cowbirds. I enjoyed the first male I’d seen in months, strutting his stuff here last week, like the male

Why isn’t the wild turkey our national bird? A. In 1784, that wise old Ben Franklin groused to his daughter, after the fact, about the choice of the bald eagle as our national symbol:“For my own part I wish the Bald Eagle had not been chosen the Representative of our Country. He is a Bird of bad moral Character. He does not get his Living honestly. …Too lazy to fish for himself, he watches the Labour of the Fishing Hawk; and when that diligent Bird has at length taken a Fish, and is bearing it to his Nest for the Support of his Mate and young Ones, the Bald Eagle
“They’re related to crows,” I said on the phone one morning to a friend, who was noting both the large numbers of Cyanocitta cristata this winter—and how much loud-mouth behavior that’s amounting to at his feeders.“Really?” he said, and then I thought what I often do when a “fact

They cover a very wide range of distances, but here’s a hint at some of the impressive extremes:Our humble barn swallow is a true long-distance migrant, and may winter as far south as southern South America, often returning to the same area year after year. Imagine: the sprightly bird that nested in the eav
“You may not (yet) know the difference between a bird’s song and its calls,” says Ellen, “but the bird sure does. It’s often sending a special message to another bird–or other birds–of its species.”In the Q&A that follows, Ellen’s answers contain green links to audio files from BirdNote’s archive that you won’t want to miss, since we’re talking sound this time.

Obviously nobody’s using my nestboxes to raise a family right now—should I take them down? A. Yes, it’s time to take down your nestbox, at least temporarily, and clean it out. It’s a good idea to wear gloves and a dust mask while you do this. Use hot soapy water and a scrub brush, and rinse it with a pot
Remember the BirdNote backstory from last week: In 2002, the then-executive director of Seattle Audubon heard a short public-radio show called StarDate. “We could do that with birds,” she thought. In 2005 the idea became a two-minute, seven-day-a-week public-radio “interstitial” (as short programs are called) that recently caught my ear. I asked BirdNote to help me answer all the recent bird questions you had asked me. (In case you missed it last week, for installment Number 1, we tackled this subject: How do birds make themselves at home—even in winter?)Parts of Ellen’s answers below are in the 2-minute clips you can stream (all in the green links–or you can read the transcripts of each episode at those links if you prefer).

He has written other titles specifically about his area of particular expertise, the corvids—crows, ravens, jays and their relatives—including one in collaboration with illustrator Tony Angell that I just read called “Gifts of the Crow,” the subject of our discussion.Read along as you listen to the Dec. 21, 2015 edition of my public-radio show and podcast using the player below.

Ellen Blackstone of the BirdNote team (who describes her job there as “writes/edits/finds photos/posts to the website/sits in on recordings”—sort of like my job at A Way to Garden) was kind and patient enough to be our teacher.

Here we go:nest, versus roostQ. The topic of where birds prefer to live, and especially the role of the nest in their lifestyles, seemed to provoke my readers’ curiosity—and also probably some misconceptions. What’s “home” to a bird? A. The great number of migratory species are all away from their nests–some as far as a different continent–during the nonbreeding season. Even among the residents, the majority of birds do not use their nest as a home but only a place to raise their young.Exceptions would be some hole-nesters that roost in their cavities throughout the year, but they are a real minority. Those might be chickadees or their cousi
