Facebird. Instagrebe. Tikstork. Linkedpenguin. Twitter. Only one of these is real, and I’m pretty sure that even on Twitter the number of actual birds participating is negligible. Birds do have social networks though—the old-fashioned analog kind, made up of flockmates and siblings and reproductive partners and rivals. Some species, like the Black-capped Chickadee, have tight-knit flocks with elaborate social hierarchies; others, like the Hermit Thrush, live most of their lives alone. These differences are surely fundamental to shaping the lives of birds, from their mundane daily experiences to how they tackle life-or-death challenges. If you spot a deadly predator like a Cooper’s Hawk, do you try to disappear quietly into the brush or do you risk your safety by giving an alarm call to warn your companions?Continue reading
Recently I flew from a particularly dire version of Minnesota winter—periodic rain making no dent in the graying heaps of snow, while rendering the smooth ice-covered sidewalks puddle-pocked and slick, so that it was not unusual to find oneself sliding inexorably down an icy slope into four inches of slushy water—into the blush of spring.
This new season was in California, where I was visiting my fiancé for the weekend. (Long-distance relationships are a staple of academia; my Minnesota labmates have significant others in Seattle and India.) Three hours on a plane headed west and I seemed to have jumped forward two months. Puffed-up robins in the snow…
…were replaced with marsh wrens singing furious declarations of their virility.
I’m not conducting junco-focused field work anymore, but that doesn’t mean I’ve lost my fondness for the little guys. I was delighted this spring to find a junco nest not five meters from my front door, well-hidden in the crotch of an ornamental tree.
The injured raptors at the wildlife rehabilitation hospital are kept in roomy metal cages lined with towels. There are pillow cases hung over the doors so that the raptors aren’t distressed by the sight of humans. The individual medical records hang on the outside of each door: Barn Owl, admitted 7/4/18, Fx L clavicle. It’s meant to be a calming environment, dim and quiet, with nothing for the raptors to do but eat their food and heal. Usually the raptors sit quietly in their cages, but occasionally there is one who throws himself at the door. You can’t see him, only hear him in his frustration: crash – crash – crash!
Most of the raptors need medications at least once per day. Liquid antibiotics and painkillers, topical eye ointments, pills. This requires one person to fetch them from their cage and restrain them from harming anyone while a second person medicates them.
While the thunderstorms and fog kept every other bird subdued, one species sang out boldly through the Smoky Mountain forests: my friend the junco. In North Carolina these juncos were not the birds I did my PhD work on, however; those were in the Oregon Junco group, with chestnut backs and sides and dark hoods, while these were in the Slate-colored Junco group, as all-over grey as their name implies. I was extremely excited when one of these new juncos decided to fly into our net so that I could take a closer look and hold a new subspecies of junco.
We head for the Smoky Mountains full of confidence: the Kentucky Warblers may have proved to be elusive, but every source suggests that our new quarry will be more forthcoming. The Canada Warbler is known to be a particularly aggressive bird, likely to respond quickly to our calls; the American Redstart is a common and easy-to-find species. We will catch them easily while enduring less moisture and fewer mosquitos than before.
We were targeting Kentucky Warblers in Howell Woods, but a few other species seem to have missed that memo. Perhaps they wanted us to study their migratory routes, too.
We have ten days in North Carolina to get DNA samples from three species breeding there. Our target for the first five days is the Kentucky Warbler, a golden bird with a black mask whose population is declining. It is a highly local bird, meaning that we can’t just find them anywhere within the shaded region of a large-scale range map: we need specific location information. We get this information from eBird, following birders’ reported sightings to a place about an hour south of Raleigh called Howell Woods.
“How did y’all find us?” asks the manager of Howell Woods. “There’s folks on our road that don’t know we exist, but somehow we get birders from Europe asking about Kentucky Warbler and Mississippi Kite. I never understand it.”
You’ve gone to peek at a nest. For a moment, all the little feathered heads regard you with large, dark eyes—and then in a flurry and a tumble they are out of the nest, running every which way along the ground, and their parents are scolding you and swooping among their babies in apparent panic. Oh no! Will the babies be okay?
This is possibly the question I am asked most frequently. Sometimes the inquirer has managed to catch a few of the babies and replace them in the nest, only for the babies to promptly hop back out. Other times the babies have swiftly vanished, and the inquirer—often someone who has watched the nest over the course of weeks, growing attached to their fluffy neighbors—is left, quite suddenly, with silence and absence and a gnawing guilt.
And that reason is that I am a hoarder. But that turns out to be fortunate, because I’ve become involved in a project that just so happens to need someone to go sample some birds for them, and I already have all the tools.
In a few weeks a co-conspirator and I will head off to North Carolina and West Virginia to chase three target species:
