We have a mammal today—and a strange one! The photo is again by Stephen Barnard from Idaho:
Pronghorn Antelope—not really an antelope, not a deer, not a goat—the only surviving member of the family Antilocapridae.
Apparently, at least according to the National Wlidlife Federation, the pronghorn (Antilocapra americana) is the fastest mammal in North America, supposedly able to attain speeds of up to 60 mph (97 kph). I’m dubious about that because it’s hard to measure such speeds. They are a conservation success: once deemed almost certain to go extinct from habitat loss and hunting, they’re now in good shape, with a population size between 500,000 and a million. This is thanks to many organizations, including the federal government and the Audubon Society, which worked together to protect their land and the crucial migration corridor (see below):
The NWF adds this:
Even more amazing than its speed is the pronghorn’s migration. Herds of pronghorns migrate 150 miles each way between Wyoming’s Upper Green River Basin and Grand Teton National Park. The only other land animal to travel farther in North America is the caribou.
We also have a bird—a female ruby-throated hummingbird (Archilochus colubris) snapped at the feeder by reader Diana MacPherson:
