Owls

In a Beijing green space larger than New York’s Central Park, biologist Bao Weidong is scanning the trees, looking for a shy bird that’s increasingly scarce: the long-eared owl. There used to be dozens of them across the city, but they’re vanishing. On the other side of the city, a wildlife rescue center is working to save other raptors that have run afoul of the city’s many perils. Can the raptors of Beijing stage a comeback, in the face of runaway development? Will the people of Beijing make room for raptors? Image Credit: Asio otus, Piet Reens.

Two Great Horned Owls (Bubo virginianus) talk to each other on a mid-march night at Peck's Lake [Arizona]. They're sitting about 150 meters apart, and a third was calling about a half mile away. These owls nest in the steep rocky cliffs around the lake and hunt in the flatlands surrounding the lake and marsh. I have "compressed" this file, the actual time between calls is about 15 seconds, but the time between the query and response is accurate.

A Black and White Owl (Ciccaba nigrolineata) sits high in a tree at El Pizote, near Puerto Viejo de Talamanca (Costa Rica), 6/22/99.

Glaucidium brasilianum cactorumis is an endangered subspecies of the Ferruginous Pygmy Owl. This little guy is only about 6 inches (165mm) tall, weighing in at 2 ounces (57 gm), yet he's been known to take birds as large as a Mourning Dove (Zenaidura macruora). His primary diet is reptiles, with an admixture of birds and insects. He's endangered due to loss of habitat in Arizona, mostly because of over development of his home range for human housing. If you are in Southern Arizona and you hear this guy's monotonous tooting (he can sometimes start at midnight and continue, virtually nonstop, until 8am and will sometimes toot more than 100 toots in a row, for months!) please call the Arizona State Game and Fish Commission or drop me a note.

A Spectacled Owl (Pulsatrix perspicillata) scolds me, as I am unexpectedly close to her child (I learn later) in the river bottom at El Gavilan, near Puerto Viejo de Sarapiqui (Costa Rica), 6/20/99.

A mottled owl (Strix virgata) calls outside our cabin at about 4 AM, 6/17/99, Monteverde (Costa Rica).

I recorded these Common Barn Owls (Tyto alba) in mid-August at Peck's Lake [Arizona]. They were sitting about a mile apart at opposite ends of the lake. Does the second sound female and the first male? They both called every 20 seconds, like clockwork, for more than two hours.

This was recorded at Elkhorn Slough in Central California, where a pair had taken up residence in (you guessed it!) a barn!
