What does the Pacific Wren hear in a song? It's a long story. What we hear as a blur of sound, the bird hears as a precise sequence of sounds, the visual equivalent of seeing a movie as a series of still pictures. That birds can hear the fine structure of song so acutely allows them to…

To find out if a crow can recognize an individual human face, Professor John Marzluff of the University of Washington wore a mask while trapping, banding, and then releasing seven American Crows on campus. Later, when he walked through the campus wearing the mask, it was automatic! A big…

While nearly a third of North American bird species are in decline, many birds that depend on wetlands are thriving. Duck breeding populations in 2009 were an estimated 25% above historical averages. Conditions on the breeding grounds have improved since the drought years of the 1980s, but…

For such a small owl, the Northern Saw-whet has a lot to say. And a lot of ways to say it. Males weigh about as much as an American Robin. And they send out at least 11 different calls, including “toot-toot-toot” advertising calls, from late January through May. The rate of calling is…

In 2014, the dams on the Elwha River in Washington State were removed. As the river ran free again, salmon from the Pacific were able to spawn upstream for the first time in 100 years, dramatically improving conditions for American Dippers. Recent research has demonstrated that birds with…

During spring at Lostwood National Wildlife Refuge in North Dakota, male Sharp-tailed Grouse - like the one pictured here - perform their elaborate mating dances on a matted patch of ground called a lek. They stomp their feet, extend their wings, and zip around the lek. Then, in an instant…

Keeping its talons tightly gripped on a branch, a Barred Owlet will sometimes lie down on its stomach, turn its head to the side, and fall asleep. A young owl doesn't fall out of the tree while it snoozes, because its back toe, the hallux, holds onto the branch. The hallux will not open or…

The story of Cygnus the Swan constellation, from Greek mythology: Phaeton, unable to control the chariot of the sun, careens wildly though the heavens, scorching the earth. The god Zeus strikes the impetuous charioteer with a bolt of lightning, causing him to fall headlong into the river…

George Archibald has devoted his life to the conservation of cranes, including the Whooping Crane pictured here. His inspiration? At the age of eight, George heard a radio broadcast about Whooping Cranes at school. He says, “. . . it was this drama of a male and female crane who’d flown…

When we think of avian migration, we generally think of birds in flight. But Common Murres migrate north by swimming. Some Pacific Coast murres paddle north to the sheltered bays of the Strait of Juan de Fuca to feed on herring and other small fish. During their ocean migration, the adult…
