Common Raven (Corvus corax)

Who’s Afraid of Corvids?

October 31, 2022 Of all the birds out there, the corvid family — the crows, ravens, and jays — might have the spookiest reputation. But this idea that corvids are spooky is far from universal — it's mainly in the Western world, as corvid researcher Kaeli Swift explains.

Ravens and Crows - Who's Who?

October 16, 2022 Is that big black bird a crow or a raven? How can you tell? Ravens (seen right here) often travel in pairs, while crows (left) are seen in larger groups. Also, study the tail as the bird flies overhead. A crow's tail is shaped like a fan, while the raven's tail appears wedge-shaped or

Raven's Love Song

February 14, 2022 Ravens are seen as tricksters in many traditions. But Common Ravens have a softer side. During courtship, a pair will often sit side by side, sometimes preening each other's feathers. And during that ritual, one or both may make soft warbling sounds. Raven nestlings sometimes make this

Bird Life at the Grand Canyon

August 30, 2021 With its awe-inspiring vistas and eons of geologic time on display, the Grand Canyon also offers a unique habitat for birds. What you're likely to see first is this Bronzed Cowbird, strutting on the lawn of a lodge or restaurant. Common Ravens call and squabble. If you're lucky, you may

Flying and Molting - A Tricky Balance

August 10, 2021 Feathers are amazing structures. But after about a year, constant use and exposure to the elements mean they have to be replaced. So how do you replace the roughly 20 feathers in each wing that are essential to flight? Many species — such as this Common Raven — molt just a few feathers at

Play and Brain Size

July 12, 2021 Many birds that play do it alone by swinging, sliding, or rolling around. Some species interact with objects, like dropping a stone and picking it up again. But a select few birds – like these crows – play with other members of their species. Scientists call this social play. It appears to

Tokens of Affection

February 14, 2021 Birds have many ways of showing affection for their partners. One way is allopreening, where a bird uses its bill to groom a mate, twirling each individual feather in its beak (like these Macaws.) Other birds present their partners with gifts like moss or sticks. A female Arabian Babbler

Tony Angell Reflects on Nature

October 18, 2020 Tony Angell, gazing on Puget Sound, writes: "From the beach below, that evocative perfume of the sea, decaying kelp, is wafted up on the breeze... Near the shore, disputing kingfishers rattle in their mercenary manner, chasing one another... Behind me, in the woods, a Cooper's hawk chants

Songbirds: The Large and Small of It

October 10, 2020 The group of birds called “songbirds” — the perching birds — is incredibly broad. Half the world’s 10,000 birds are in the songbird group, and their range of body sizes is mind-boggling. One of the smallest songbirds in North America is the Golden-crowned Kinglet, barely larger than a

Ravens and Wolves

October 3, 2020 Researcher Bernd Heinrich writes: "Ravens associate with any animals that kill large game - polar bears, grizzlies, wolves, coyotes, killer whales, and humans." These birds travel with caribou on their migration, and scavenge remains after wolves have made their kills. The bill of the

Tony Angell on the Raven

July 20, 2020 Tony Angell reflects: "It's a cloudless summer day as I listen to ravens behind me in the woods. There's an endless repertoire of croaks, krawks, barks, yelps, and yodels. Other ravens across the bay respond in kind, and I imagine that this is a day of poetry and perhaps a few jokes shared

Convocations, Coveys and Charms

November 22, 2019 Everybody’s heard of a gaggle of geese and a covey of quail. But what’s a group of penguins called? And a “conspiracy” of ravens? Maybe the way we label birds says more about us than it does about them. Support for BirdNote comes from American Bird Conservancy and Bringing Back the Birds

City Ravens

May 30, 2019 Once common on the Atlantic Coast, Common Ravens became rare, as human activity grew more obtrusive through the 1900s. But something changed around the dawn of the 21st century. The ravens came back. Ravens now patrol parking lots in New Jersey to seize the choicest trash, dodge speeding

Mating for Life

February 10, 2019 Most bird species in North America mate for a single breeding season. Some may team up again the following year, just because both stay in - or return to - the same territory. Fewer than one-fifth of Song Sparrow pairs are reunited. Hawks, eagles, and ravens have wide territories, thus few

How Raven Made the Tide

August 19, 2017 Long ago the tide stayed close to shore. The people went hungry because the clams lay hidden under water. Then Raven had a plan. He put on his cloak and flew along the shore to the house of the old woman who held the tide-line firmly in her hand. Raven fooled her, and she let go of the

Christmas Bird Counts at the Extremes

December 22, 2016 This winter, volunteers will tally birds in more than 2,000 locations as part of the annual Christmas Bird Count.

Raven, Dog, Bone

October 12, 2016 Ravens are crafty! BirdNote listener Gary Cummins tells a story about the intelligence of ravens. When he worked at Grand Canyon National Park, Gary had a Siberian husky named Tasha.

Hello, Macaw - With Tony Angell

September 18, 2015 Artist and naturalist, Tony Angell, describes his communication with Macaw, a raven that came into his life and home. "I would say, 'Hello, Macaw,' and his communication to me was often to lean over for preening. Eventually, the arrangement became so routine to Macaw that something had

The Royal Ravens

November 12, 2012 The Tower of London has a long and notorious history of murderous political intrigue, dungeons, and famous beheadings. And for more than 300 years, the tower has also been home to a set of royally maintained ravens. Since the time of Charles II, at least six ravens have - by royal decree -

Raven and the Winding River

March 15, 2011 Many years ago, when rivers began flowing from the mountains to the sea, the animals couldn't agree on their course. Raven wanted the rivers to turn and wind, so that as he flew up and down them, he would have different views at every bend. Mink disagreed. The loud and raucous Raven
