Populations of California’s already endangered tricolored blackbirds (Agelaius tricolor) have fallen by 44 percent since 2011 and 64 percent since 2008, according to a survey coordinated by the University of California, Davis.
How do you gather information about a bird species that spends 99 percent or more of its time at sea? Until recently, there wasn’t an easy answer.
You have to hike a pretty long distance if you hope to see the critically endangered bird known as the palila (Loxioides bailleui), but if you’re lucky and work hard, you can walk their entire habitat in a single day.
In order to get more information about the forest here at the Sikundur research station in North Sumatra, I've set up four camera traps, which I'm using to get a better look at the wildlife around the site.
Several times a week, if not every day, I look at Doppler radar maps so I know whether to take an umbrella when I leave the house. These maps, shown on TV weather reports or websites, are commonplace enough that they don’t feel like impressive technology: mere green blobs slowly shifting across the screen at [...]
Few people have ever seen a Jerdon’s courser (Rhinoptilus bitorquatus), a critically endangered nocturnal bird that lives in a tiny scrub forest in southeastern India.
Science has a fairly bland name for the national bird of Samoa: the tooth-billed pigeon (Didunculus strigirostris). The bird’s name in the Samoan language, however, is much more colorful: manumea.
The behaviour of long-extinct animals remains an area of major public and scientific interest the great perennial problem being that were always massively constrained, if not crippled, by a frustrating lack of data.
The best Halloween stories are true. There is a lake in Tanzania, Lake Natron, that is so hostile to life that only two species, alkaline tilapia and blue-green algae can live in its deadly waters.
Most people in Los Angeles interact with seagulls – that is, the California gull, Larus californicus – mainly by shooing them away from our picnics at the beach.
After setting camera traps to study tigers, researchers received a surprise when they found the world's first recorded evidence of a golden eagle attacking a sika deer.
Every now and again I make an effort to get through a little bit more of passerine bird diversity (see the list of articles below for previous efforts).
The world’s 100 most endangered and unique birds have been ranked in a newly published study, and the list includes a corpse-eater with legendary skills of decapitation, a shameless self-inflator, and the world's heftiest parrot.
Are four treats better than two? Not if you're a crow picking a favorite snack. Crows and ravens hold off on gobbling a tidbit when they can see a better one coming after a short wait.
If you pay any attention to the world of zoological research (as you will do, given that you're reading a blog called Tetrapod Zoology), you'll know that the study of anatomy has very much come to the fore in recent years.
A couple of weeks ago I hatched a plan to write about all the neat new dinosaur-themed studies that had just appeared in print; I began by penning my thoughts on the Brontosaurus issue.
Higashijima Island doesn't look like much from the sky. This tiny, uninhabited scrap of land 1,000 kilometers south of the coast of Japan is only a few hectares in size.
Following on last week’s California gull photo, here are a few more from that day. It’s a lesson in composition: the top photo tells a story.
The number of exhibits combining science and art in some capacity has grown steadily since I began blogging about them in 2011. With exhibits in galleries and museums across the country, there’s something for everyone.
Spear-billed, long-necked, wading marsh dinosaurs that eat... well, whatever they can catch and cram into their throats
