The early stages of a scientific career are designed to be unstable, slingshotting you from place to place as you acquire new skills. I bucked this paradigm somewhat in the first years after finishing my PhD, teaching and working on local projects in order to stay in the Bay Area; but the lure of learning from a cool new lab (and having health insurance) proved irresistible. At the end of August this year I moved out to Minneapolis to start a postdoc.

The best deer
My first thought was that the stag was badly injured. He trotted across the rural Wyoming highway wrong, dipping with every third step. Clipped by a car, maybe, I thought, mentally cringing at the internal damage that would have done. I pulled over on the shoulder, but by the time I got out of the car he had vanished.
The land was only moderately hilly, so I could see for a good distance, and the grass was waist-high on me: not nearly tall enough to hide an adult deer. I had taken my eyes off the stag for just a moment and now he was gone. All I could see was a flock of small birds swirling in agitation over the ditch at the side of the road.
They fly at you, shrieking
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.

Unusually heavy rains have put much of the banding station underwater for the past three months. One side effect of this is that, on the days when the area is sufficiently dried out for us to squelch out in our rubber boots and band birds, the mud shows the tracks of everyone else who has been out there before us.
Usually the denizens of the banding station of whom I am aware are the birds we catch in the nets and band. These tend to be small- to medium-sized songbirds. The mud reveals an entirely different set of creatures living in the area.
Planet Earth II, the new BBC documentary narrated by Supreme Voice of Nature Sir David Attenborough, devotes one of its six episodes to animals living in cities. It’s unsurprisingly great. (Even if the ultimate masters of urban living, pigeons, who you might expect to be celebrated in this context, instead spend the episode getting unceremoniously eaten.) The “Cities” episode has to walk a delicate line, heralding animals’ ability to adapt to human landscapes without failing to acknowledge that humans overwhelmingly destroy habitat rather than creating it. It mostly leans to the optimistic side of the line; one segment makes New York City seem like a wildlife paradise.
The darker side of cities is represented by a segment on hatchling sea turtles. The turtles use the shine of moonlight on water to guide them from their nest in the sand into the ocean. Unfortunately, we humans love to shine lights even brighter than the moon, and more than half of the tiny turtles are drawn away from the ocean by the city’s lights.
As Attenborough narrates, footage rolls of the baby sea turtles gamely clambering across sidewalks and onto busy streets, heading for the ocean that isn’t there. The bodies of roadkilled turtles are visible in the background. One turtle makes it across the street, then tumbles halfway into a storm grate and gets stuck, lost to view save for one forlornly-waving flipper.
As soon as the episode ended, I began typing into Google: “planet earth 2 did”—at which point Google helpfully autocompleted the rest of the sentence: “planet earth 2 did they help the turtles“. Everyone else who had seen the episode wanted to know, too.
Like elephants or dinosaurs, male Northern elephant seals on land are massive past the point of useful reference. A 5000-lb animal falls off our everyday mental scale; it’s just enormous.
Yet, lounging around on the sand at this time of year—their mating season—these beasts look like they need some band-aids and Neosporin. Their thick, strong hide is marred with new gashes laid over old scars. Titans they may be, but even titans can fall when they square off against other titans.
Animal accomplishments that have caused my students to break into applause
I’m teaching an Animal Behavior course this semester. The lectures are 80 minutes long and exactly during the sleepiest time of the afternoon; I enjoy the challenge of getting a reaction from the students under these circumstances. Videos of baby animals in peril always get attention (some good ones: marine iguana, barnacle goose, water buffalo), but they’re so reliable it almost feels like cheating.
My students have actually broken into applause during lecture three times so far. One of these will not be discussed in detail (it involved the recitation of poetry), but the other two were in response to two quite different animal accomplishments, which I thought I would share.
Birds looking odd? They may be molting
After breeding, if you’re a bird, comes molting. Time to discard those old, worn, raggedy flight feathers and start with some fresh ones for the long haul of the fall molt, or replace sparse downy feathers with good warm ones for the cold of winter. This means that around now—from mid-July to September—you may see a lot of birds who aren’t looking their best.
Look at all of this egret nonsense
The egret chicks at the nesting colony are growing. They’re doing some neat stuff as they grow, like practicing walking very carefully along branches.
But they are also getting up to a lot of nonsense.
Siblings! No fighting, no biting!
