Ephraim Heller sent us a passel of lovely brown bear photos (and, oddly, one of an elephant), all  save the pachyderm taken in Alaska. (They are of course also known as “grizzly bears”.)  Ephraim’s notes are indented, and you can enlarge the photos by clicking on them.

I traveled to Lake Clark National Park in Alaska to photograph its famous coastal brown bears (Ursus arctos horribilis) as they clammed and fished along the coast of Cook Inlet. I stayed at a remote lodge on the coast. It was a mixed experience. During the week I was there I saw only a few individual sows and cubs, far fewer than expected (the boars tend to stay inland at this time of year). However, the sows loitered in the area, so there was plenty of time with them. When it was just the bears, the guide, and a few other guests, the photography was spectacular. Unfortunately, that was seldom the case. The few bears were more often mobbed by folks on bear-watching tours arriving from other lodges, small planes, and boats. At times, I counted up to 35 people watching a single bear. In crowds that large, you put your camera down and just enjoy watching the animal.

Now that I’m done with the kvetching, let’s get to the photos. For those who care about such things, all the photos were taken with a Nikon Z8 or Z9 camera and either a Nikon Z 70-200 lens + 1.4X teleconverter or a Nikon Z 24-120 lens.

When there were no crowds and I saw a bear approaching from afar, I made my first attempts at using a remote trigger. This involved: putting my camera and wide-angle lens on a low tripod at a location where I thought the bear was likely to pass; stepping away to a distance of about 30 feet; and triggering the camera with a remote shutter release. Most of these attempts ended in failure, as the bruin chose a different path. But occasionally, it worked:

Brown Bear at Lake Clark:

At other times, I just lay down in the mud and hoped that an approaching bear would walk nearby. It was quite safe, as there are so many clams and salmon to eat that they aren’t interested in eating me. I would certainly not do so with bears from the interior, who are typically hungrier and more aggressive:

A sow out for a stroll on the beach:

Ninety percent of the shoreline is made up of salt marsh, sand, and mud. Multiple rivers flow into Cook Inlet, creating a habitat containing three distinct food sources: protein-rich salt-marsh sedges, intertidal clams, and late-summer salmon. Park biologists have counted as many as 219 brown bears in a 54-square-mile coastal block. Those densities are possible because the food is concentrated and the bears have learned to tolerate one another.

Here’s a sow patrolling along a salmon stream. These two shots were taken with a remote trigger:

Taking a load off her feet:

Coastal and inland bears in the park are the same subspecies, but they live different lives. Inland animals travel farther for scarcer resources and remain more solitary. Coastal bears grow larger because marine-derived protein is available for months.

Another shot taken with a remote trigger:

This bear is looking for salmon at a river mouth at low tide. The following photos were taken as I in the mud flats. My waders kept me mostly dry, albeit mud-covered:

After den emergence in April–May, lean bears head first to salt marshes. These wetlands occupy less than 1 percent of the park yet supply Ramensk’s sedge (Carex ramenskii), an early-season protein source. Bears graze for hours like cattle.

When the sow spots a fish at the river mouth, she rushes over to seize her prey:

A few yards seaward, the intertidal flats hold clams, particularly Pacific razor clams (Siliqua patula). These are a year-round protein source that bridges the gap between spring vegetation and summer salmon. The tides were over 20 feet when I visited, and at low tide the exposed mud flat stretched out for hundreds of yards:

Clamming is a learned skill. Cubs watch their mothers. Novices dig randomly, excavating large, unproductive craters and then crunching whole shells. Experienced bears read siphon holes and slight depressions, work specific slope and sand textures at the lowest tides, and extract dozens of clams in a single low-tide window. The most efficient animals pry shells open with claws rather than crushing them and slurp the meat. Different individuals invent slightly different techniques.

Here’s a sow digging for clams in the mud flats. I don’t include many photos of bears clamming because photos of bears with their noses stuck in the mud just aren’t that interesting or pretty:

The Jesus bear subspecies walks on water. Or, perhaps, the mud flats extend for hundreds of yards at low tide:

By July and August the rivers fill with sockeye and other salmon. Park-wide sockeye salmon (Oncorhynchus nerka) runs have ranged from 150,000 to more than 3 million fish. Bears shift from meadows and flats to stream mouths and shallow riffles. Techniques range from patient standing to explosive pounces. Experienced animals may catch dozens of fish a day and often eat only the most energy-dense parts (brain, roe, skin) before discarding the rest. This sow has caught silver or coho salmon (Oncorhynchus kisutch):

I’ve written Ephraim for a replacement photo, but in the meantime enjoy this elephant picture:

If you visit, remember to carry bear spray. Bears like the pepper flavor:

Note: That was not my bear spray!

I kissed a squirrel and I liked it

September 5, 2026 • 8:15 am

Yesterday, after second lunch for the ducks, I was chatting with a grad student in medical research when I was—as I often am—besieged by squirrels begging for nuts.  After several months of getting them habituated to me and to the way I look and smell, I have made them fairly friendly (I want to avoid bites at all cost!)

At this point several of them will climb up my leg and onto my shoulder for a nut.  When they do that, only a quick turn of the head is necessary to allow me to kiss them on their furry flanks.

See below for the short video showing this. The smack of the kiss is audible.

I can now credibly claim that I am the only person at the University of.Chicago who has kissed a squirrel. I may be the only person in the history of the University of Chicago who’s done this.

If any readers have osculated a squirrel, let me know below.  (h/t to the woman who took the video).

And here’s another squirrel begging for a nut, unaware that his face is decorated with a leaf. With his eyes on the sides, perhaps he can’t see it.

Very few people are sending in wildlife photos, so if you have some good ones, shoot them my way, please.  Fortunately, ecologist Susan Harrison has come through with another batch from Oregon. Susan’s captions are indented, and you can enlarge her photos by clicking on them.

Mt. McLoughlin, Oregon  

In southern Oregon at the tail end of summer, climbing a volcano to look for Gray-crowned Rosy-finches (Leucosticte tephrocotis) seemed like a fun thing to do.

Gray-crowned Rosy-finch (photo from AllAboutBirds):

Per AllAboutBirds, “This delicate pink-and-brown songbird is among the hardiest of all birds. Gray-crowned Rosy-Finches nest in the highest parts of the highest mountains in North America… they forage, seemingly at complete ease, on snowfields, forbidding talus slopes, and in high winds or snowstorms… (It) probably holds the record for highest-altitude breeding bird in North America.”

Who could resist looking for such superlative birds??  It required only a day hike to a 9,500-foot peak not far from my home base in Ashland, Oregon. The peak, Mt. McLoughlin, is just north of Mt. Shasta in the Cascade volcanic chain. The trail goes up its east (= right, in the photo below) side.

Mt. McLoughlin from the south:

Hikers often get lost as they descend the peak.  Near the summit there is no clear trail in the loose ash and talus, and if you start a few degrees off-course you’ll end up far from your destination.  Accordingly, there are many warning signs and route markers.

Trail warning sign:

The last half-mile to the summit is steep and slow going.  This is the likeliest place to see Rosy-finches – which, alas, I did not see.

Approach to the summit, with trail on the left:

However, I did make it to the summit and back safely!

Summit:

The main birds I saw at the top were several Rock Wrens (Salpinctes obsoletus) and a pair of Sharp-shinned Hawks (Accipiter striatus) chasing around a Northern Harrier (Circus hudsonius).

On the descent it became easier to pay attention to other small wildlife.

Bruce Lyon has returned with Part 2 of his adventures with Arctic foxes, including photos and several videos.  Bruce’s captions and narrative are indented, and you can enlarge his photos by clicking on them.

Here is a second batch of photos and videos of arctic foxes (Vulpes lagopus) on St Paul island. First batch here.

A parent resting by its den:

Below, a video from a couple of years ago of a very tame fox at the dump. Every time I went to the dump to check on some rosy-finch nests, this individual would run up very close to me and run circles around me, whining and barking and jumping up at me. I was amused and thought the fox was being friendly and curious but another biologist told me that this could be aggressive behavior—perhaps the fox was defending its den a bit too aggressively. That biologist had been bitten by foxes before:

This year we had a similar close encounter of the fox kind but this fox was at the harbor for the food and did not seem to have a den nearby. It seemed genuinely playful and curious and was particularly keen on nibbling my assistant’s rubber boots. Who doesn’t enjoy a chaw of boot rubber once in awhile?:

Earlier the fox in the above video had been munching on a clam that it probably got from the nearby pile of dredge material being scraped up from the floor of the harbor in a harbor improvement project. The dredge sediment seemed to be chock full of inverts like clams and seemed popular with at least a few foxes.

Back to the foxes with dens close to our lodging—one of these adults takes a large salmon tail to its pups:

If the pups are hidden in the den when a parent arrives with food the parent will sometimes just dump the food on the nearby beach for the pups to find later. The thick-billed murre carcass in the photo below was lying on the beach for some time before a pup finally discovered it:

Food fight or play? A couple of pups squabbled over a dead crab. I didn’t see much in the way of them eating the crab—either the crab was too far gone to be worth eating or the shell was a barrier:

A few photos of pups playing around the two dens near my lodging:

The pups do a lot of pouncing—here a pup pounces on a piece of cardboard:

Below, but it’s much more fun to pounce on a sibling:

Sometimes the squabbles among the pups seem like real fights. Below is a video of a family that had a den under a large metal CONEX container in town. Two of the pups seem to be having a serious fight, evidenced by the screaming. Normal play is not accompanies with this screaming. Perhaps these squabbles are used to establish dominance. Some studies have observed dominance hierarchies among the pups—the dominant individuals defend prey items and also take it from subordinates:

Here’s a video of the same family with a more playful scene:

Adult foxes that I at first thought were playing were more likely having a serious fight. This was near the harbor on a day when there were a lot of foxes hanging around, most of them peaceably. I saw these two foxes in the middle of the road, seemingly frolicking. One of the foxes was on its back in the typical dog submissive posture while the other was standing over it. All of a sudden the  one standing went at the submissive one, which ran like hell, right towards me. Look at the glorious fluffy tail on the fleeing animal!  My colleague Paula White, who has studied this population of foxes, tells me that fleeing subordinates often wave their tails in the face of the pursuers. Perhaps it is better to get bit on the tail than the butt? Waving a fluffy tail might also distract and confuse the chaser:

I will end with a family portrait:

Evolutionary ornithologist Bruce Lyon has sent us a batch of lovely photos from his field work in Alaska, including baby Arctic foxes! (He works on birds, though.) Bruce’s captions and IDs are indented, and you can enlarge his photos by clicking on them.

Here is a post on the arctic foxes (Vulpes lagopus) of Saint Paul Island, Alaska, where I spent the summer studying songbirds. Two years ago I shared some photos of foxes and text (here).

Arctic foxes are native to St Paul Island and virtually all individuals are blue-morph rather than white-morph foxes. Occasionally, white morph individuals do get to St Paul by crossing the winter sea ice. The morphs are apparently produced by a single Mendelian gene (the MC1R gene).

This year we had two dens that were very close to each other (150 meters apart). We could observe both dens from the windows of our lodging. Often the foxes are nestled away out of sight down in their dens. However, because we could watch the dens from our apartments we noticed whenever the pups were out and being active (mostly playing). If the activity seemed particularly fun I would hop in our truck and drive the 30 seconds it took to be right next to the dens (plus the vehicle serves as blind for close observations). One den had nine pups, the other five, and the pups sometimes joined together in a giant heap of fuzz all playing together , with some of the more excited ones jumping up and down like fleas. I am not sure how typical it is for pups from adjacent dens to have playdates!

The view of the salt lagoon and downtown St Paul and harbor in the back. At low tide the area to the left is one huge beach and the foxes frolic here. The dens are out of view to the left of the photo:

Portrait of an adult fox. The eyes are an interesting amber color:

The harbor sometimes has a large numbers of foxes; they scavenge the discarded parts of fish after the fish are cleaned. On one harbor visit we saw 20 foxes hanging around the harbor rocks, all fairly close together. A plethora of foxes!

A typical dark colored fox on the rocks:

A rare white morph individual:

The individual below looked like a sheep badly in need of shearing and we thought it was amusing—sadly, it turned out to be a sign that the animal is not doing well. All of the foxes molt their winter coats but arctic fox expert Paula White told me that the animal in this photo probably has a disease called Shaggy Lame Fox Syndrome. Paula thought this because the animal has a swollen ankle and animals in poor condition often molt later than healthy animals. This disease is apparently found only in Pribilof populations of foxes. Symptoms include “failure to shed winter pelage and moderate to severe polyarthritis”. Paula pointed out to me that this animal has a swollen front ankle:

The pups are adorable and I will share a few photos of them. I think ‘cute and fuzzy’ pretty much captures their essence:

Whenever I made a mouse-like squeaking noise the pups would cock their heads:

A sibling makes a good pillow:

One day from my window I saw an adult fox trotting across the sand flat near its den carrying what I thought was a gull but turned out to be a northern fulmar (Fulmarus glacialis; seabird related to albatross). The adult dropped the prey on the sand some distance from the den and the pups from the closest den (with nine pups) raced out and piled onto the carcass.  I quickly drove out to get closer and noted the adult was concerned about something. It then gave an alarm bark and everybody scattered. Less than a minute later the pups returned. Then an adult showed up, wrestled the carcass from the pups and took it to the other den. It seems that an adult from the second den came in and stole the prey. I am not sure why the fox who brought the fulmar in did not try to chase the thief off. The two dens do not seem hostile to each other generally because sometimes the pups from the two dens mingle and play together. Perhaps the adults are related?
 
The adult trotting with the fulmar:

What a northern fulmar (Fulmarus glacialis) looks like when it is not dead in the mouth of a fox. They are quite pungent smelling—to me it is almost a mothball smell. I can imagine that they have a funky flavor but these foxes seem to eat almost anything.

I do not know how the fox got the fulmar. Perhaps scavenging a dead one? However, these foxes are very good at climbing cliffs and it is possible that the fox ambushed a fulmar near its nest on the cliffs. In the photo below, a fox takes a nap half way up a cliff:

Back to the drama. After dropping the fulmar on beach the parent seemed to be wary of something, and gave an alarm bark:

A bit later, the adult thief comes in to take the carcass while a pup bravely tries to scare it off”:

A tug-of-war followed:

Of course the adult won, and ran with the carcass the 150 meters to its own den:

The thief with its booty close to its den:

In light of the absence of reader contribution, but delighted to show such lovely photos, I present some of Dr. Scott Ritchie‘s photos from last October (his FB page is here). Note that the photos include NUMBATS (Myrmecobius fasciatus), which are endangered. Scott hails from Cairns in Australia.

Scott’s captions and IDs are indented, and you can enlarge his photos by clicking on them.

Some really cute mammals from Dryandra, SE of Perth. The forest area is home to the critically endangered Numbat. I was really pleased to see this cute little fella, and get some decent pics. And here are a few birds from the area too.

Looking for his brother. He caught a bit of golden light before sunset.

Oh, there he is!

Hop to it!

August 1 ducks

August 2, 2026 • 8:15 am

“How is the Duck Family doing?”, you ask.  They’re peachy—couldn’t be better. Today is the two-week anniversary of when they came to Botany Pond, and Miss Duck and her Brood of Four are healthy, happy (as far as I can tell), vigorous, and certainly well fed.  You’ll see below how the babies have grown: they now have pointy tails, are at least twice as large as when they came to the Pond, and soon will enter their awkward teenage phase as their feathers start to come in.

All the ducks know me and come to me when they see me at the pond; I don’t even have to whistle for them. I am their Human Food-Vending Machine.

For two of the last three mornings, they were waiting for me at the bottom of the stairs leading from my building to the Pond, and when they saw me they came waddling and strutting up. As you can see below, the babies were peeping and Miss Duck was making soft quacks because she wasn’t quite sure of my intentions. I herded them to the water in the channel, as I always feed them in the water—it makes less mess if there is uneaten food. (The fish and turtles get it quickly in the water.)

Miss Duck, unlike other hens I’ve tended, is frightened of the large turtles, quacks when they approach (the babies don’t care), and swims away from them. She feints at them with her bill, and sometimes at the fish as well. But I manage to get enough food in them all to keep them fat and growing. (They get fed three or four times per day).

So here’s what greeted me yesterday morning when I came to the Pond about 6:30 a.m. You can hear me speaking to them, as a duck expert told me that they will also recognize my voice. Although my vocal timbre changes, I don’t speak to them like one who speaks to a child, for I think animals should be addressed as adults.

Sound up on all videos.

After breakfast in the channel, the family invariably swims back to the main Pond, deciding to settle on one of the three or four rocky spaces where they can dry off, rest, and digest. Here they first try the “Sacred Rock” in the NW part of the pond, and then settle on the big flat rock between the benches.

Look how they’ve grown!

Yesterday morning there were fairly heavy rains, but the ducks were all dry when they came for food after the rain stopped. I have no idea where they go to stay dry, as when it rains heavily you simply can’t look over the Pond in person without getting drenched. Here they are after the rain in a screenshot from thePondCam. Can you find Miss Duck and her ducklings?

Finally, a first yesterday: a rabbit appeared at the Pond. Though Hyde Park is full of Eastern Cottontails (Sylvilagus floridanus), I have never seen one at Botany Pond. If it hangs around I may try to feed it, though I’m wary of that Cooper’s Hawk who sometimes comes by.  The arrow points to the bunny.

I’ll do my best to provide updates, but I just changed Big Computers and that always causes problems and stress, in this case with uploading pictures and videos. Stay tuned: you will not miss the ducklings growing up!
