Live-trapping lynx in the far north
Knut Kielland, a professor with UAF’s Department of Biology and Wildlife, used to trap lynx for their fur. Here, he has captured this 22-pound female lynx as part of an Alaska-wide project he leads to better understand the ecology of the animal.

Happenings north of the Arctic Circle
Though the calendar calls it springtime, the thermometer on the truck reads minus 28 F on this sunny morning a few days past spring equinox. I am riding shotgun with Knut Kielland, an ecologist at the Institute of Arctic Biology at the University of Alaska Fairbanks. He has invited me to join him for a week north of the Arctic Circle — 66.6 degrees north latitude, about 150 miles from Fairbanks.

Caribou cams give insight into secret lives
Caribou wearing cameras around their necks have filmed a secret world of mushroom nibbling, desperate head-shaking during bug episodes, and nuzzling of wet newborns seconds after they fall to the tundra.

Listening to the voices of killer whales
Hannah Myers has listened to many hours of orca calls in the Gulf of Alaska. The University of Alaska Fairbanks graduate student often knows a killer whale’s family group after hearing just a few syllables of its call.

Blown back to Alaska, bird perseveres
A bar-tailed godwit recently arrived in New Zealand on its second attempt to get there from Alaska, after a storm had blasted it back north. Keith Woodley of the Pukorokoro Miranda Shorebird Centre on the North Island of New Zealand reported that a male godwit carrying a satellite transmitter first left the mudflats near the Kuskokwim River on Sept. 11, 2021.

Shorebirds depend on wee slivers of Alaska
Pencil-beaked shorebirds with the ability to stay airborne for a week — flying all the way from Alaska to New Zealand — rely on a few crescents of mudflat to fuel that incredible journey.
Scientists recently found that almost the entire population of bar-tailed godwits that breed in Alaska fatten up on clams and worms on ephemeral sand bars just west of the mouth of the Kuskokwim River. In autumn, 80 percent of the birds rest and feed on islands within 15 miles of one another.

Fluorescent bill may be seabird’s neon sign
The crested auklet looks like a smiling clown that never blinks. It is probably the only seabird that smells like a tangerine. Its beak — the color of a tangerine — is so bright a scientist thinks it may be fluorescent.

Setting traps to catch an Alaska virus
On this crisp, cool fall day in 2021, this trapper — who lives in Atlanta and works for the Centers for Disease Control and Prevention — hunts for a virus that was unknown to humans until 2015. That’s when a Fairbanks doctor examined a lesion on a woman’s shoulder.

Pine grove near Yakutat is farthest north
We were on the Yakutat Forelands — a sweep of forested lowlands left behind after glaciers retreated from the landscape hundreds of years ago. Taking steps that felt like walking on a trampoline, we moved through a pine grove in a few-acre spread of open green muskeg.

Visit to glacier begins with wildlife encounter
We heard a loud buzz. A hummingbird hovered in front of my cracker. As I held still, the hummingbird probed the peanut butter, twice, with its needle beak. The cracker transferred the vibration to my left hand, tickling my fingers. As the bird zoomed off, I looked over at Ben to confirm the experience.
“I think you have superpowers now,” he said.
