Well, this is the last batch of photos I have, so you know what to do.

Today’s contribution is from Ephraim Heller, this time with photos from America rather than Brazil. Ephraim’s captions and IDs are indented, and you can enlarge the photos by clicking on them.

It has been a busy January on the Snake River in Grand Teton National Park.

After a warm early winter, a few weeks ago we finally had a hard freeze. A branch of the Snake River froze solid. However, there is a location where a warm spring feeds into the branch and this inlet stayed open. Hundreds of Utah sucker fish (Catostomus ardens) were trapped in this area of open water surrounded by ice, isolated from the main body of the Snake River. Naturally, this provided a smorgasbord for the local bald eagles and coyotes.

As I observed the Utah suckers at various times of day, I noticed that in the late afternoon they would all rise to the surface and expose their dorsal fins. Intrigued, I queried my AI which informed me that this is a matter of oxygen dynamics:

  • The warm water holds less oxygen than cold water, and thermal springs typically have low dissolved oxygen content due to high temperatures.
  • In confined areas with high fish density, oxygen is rapidly depleted.
  • Fish respond to low oxygen levels by “piping” or “aquatic surface respiration” (ASR) when oxygen levels drop below critical thresholds. This behavior involves positioning at the water surface with mouths/dorsal fins exposed to access the oxygen-rich surface layer. This behavior indicates that the fish are stressed.

However, the AI also stated that “Aquatic plants produce oxygen through photosynthesis during daylight, with peak production in late afternoon. At night, plants consume oxygen through respiration. Dissolved oxygen levels are highest in late afternoon and lowest just before dawn.” This doesn’t seem consistent with the timing I observed.

I don’t know how much of this is true vs. AI hallucination, but it sounds plausible to me. I’d appreciate it if the ichthyologists and limnologists among the readers would confirm or refute this story.

Now for the photos:

Here are the Utah sucker fish at the surface of the open water pool in the evening, trapped by the surrounding ice:

Here is a close up of the fish at the surface:

Every so often the fish would go into a frenzy at the surface. I don’t know why. It was unrelated to anything I saw happening at the surface. Here is a bald eagle (Haliaeetus leucocephalus) watching the frenzy and assessing his menu options:

Having made up his mind, the eagle helps himself to a serving of fresh fish:

The common ravens (Corvus corax) have found a lovely rotting fish. Instead of exerting the effort to catch a fresh fish, this eagle has decided that it is easier to steal the carrion:

Bald eagles are kleptoparasites, so when an eagle with energy and initiative catches a fish the other eagles won’t let him dine in peace:

Ravens are smart birds. This one is surely thinking “If those eagle ignoramuses can catch a fish then surely I can do it better.” Unfortunately for him, the fish got away:

In spite of their inability to fish, common ravens are handsome birds:

To my surprise, the North American river otters (Lontra canadensis) who live half a mile downstream have not been dining at the buffet. I think it is because this branch of the river is frozen solid and the otters don’t like traveling on the ice surface for long distances without the safety of accessible water. So I donned my cross country skis and visited them at another, unfrozen branch of the Snake River. They, too, were feasting on Utah suckers:

Also on the river are trumpeter swans (Cygnus buccinator) in the morning mist:

Trumpeters need a long runway to take off. These four are just starting to accelerate:

Once airborne they are graceful:

Finally, this old-time general store sits adjacent to the Snake River in Grand Teton National Park. In this star trail time lapse, the stars are, of course, circling Polaris, the north star. The Tetons are to the left of the store:

I now have two sets of photos after this one, but I’m still nervous. If you have good wildlife photos, please sent them in. Thanks!

It’s been a cold week in Chicago (right now it’s 9°F or -13°C), and it’s going to be cold this coming week as well. I hope the turtles at the bottom of Botany Pond are okay. But given the weather it’s appropriate that today we have photographs of Antarctica from reader Paul Turpin.  Paul’s captions are indented, and you can enlarge the photos by clicking on them.

My brother Mark recently returned from a cruise to the Antarctic on the Scenic Eclipse. I told him you loved penguins and he gave me permission to send you these photos.  I believe these are all gentoo penguins [Pygoscelis papua] except for one which included a chinstrap friend [Pygoscelis antarcticus].  The open water photo is when they were at the Antarctic Circle.

Thank Ceiling Cat that two readers came through with photos yesterday. Today’s batch includes not butterflies but vertebrates, and is from  Pratyaydipta Rudra, a statistics professor at Oklahoma State University, and his wife Sreemala. The pair share a big bird-and-butterfly website called Wingmates. Their captions and IDs are indented, and you can enlarge the photos by clicking on them.

The river otter images from a recent reader’s wildlife photos section inspired me to put together this batch of photos from our fall trip to Southeast Oklahoma when we stumbled upon a group of river otters. Otters, in general, are my favorites due to their fun characters and cool behaviors. However, I was never been able to see North American river otters (Lontra canadensis) close enough to get good enough photos until this encounter.

We (my wife Sreemala and I) were hiking along the river just after sunrise with the hope of finding some cool critters while also enjoying the beautiful foggy atmosphere and the fall foliage. Only a few other people were out at that time. A lady who was coming back greeted us, and noticing our long telephoto lenses, told us that she saw some animals floating on the water that looked like rats. We immediately got excited thinking they must be otters since the other “rat-like” animals such as muskrats or beavers would be pretty unlikely in the fast-flowing stream in that area. River otters, on the other hand, especially enjoy the fast flow and the cascades. Within a few minutes, we were able to locate a group of at least six of them fishing next to the cascades.

Some of them soon moved up on a rock (across the river from us) for resting and doing some morning yoga as we snapped a few photos:

The river otters are quite social, and it’s fun to watch them interact with each other. We watched them for a while and they were quite aware of our presence, but they went about with their own business of grooming, catching fish and crawdads, etc.:

Here are a couple of them swimming in a relatively calmer stretch of the river with reflection of fall foliage:

But, most of the time, the otters stayed close to the cascades. I think it is easier to catch the fishes there as they pop up more, but I might be wrong. You can also see a human (Homo sapiens) fishing in the distance:

Another image of the fast-flowing river with the light of the rising sun on the trees bordering it:

Most of these wider images are captured using my cellphone. I clearly remember that this was the day I figured out that I could capture slow shutter photos using my cellphone and got so excited that I kept taking photos of the stream with different compositions:

These next images are all from one of my favorite parts of Oklahoma. This region in the southeast part of the state features beautiful hilly areas and several small rivers and creeks flowing through them, creating some wonderful scenery— especially during the fall. The two things that make these fall experiences absolutely wonderful are bald cypress (Taxodium distichum) trees and fog along the rivers.

The fall colors on the bald cypress are very different from what most people think of when they think of fall foliage. The fine textures along with the burnt orange coloration make them quite unique. Add to that the fact that these trees can stand right in the water developing “knees” that grow upwards from their roots. There are different theories on what utility they might provide. I am not a biologist so, I will stay away from claiming I understand them:

Here is another creek in the same area that had calmer water allowing for nice reflections of the bald cypresses along it:

Lights and shadows along the creek…:

A White-tailed Deer (Odocoileus virginianus) peaked through the forest:

A handsome Black Vulture (Coragyps atratus) against the fall foliage:

Great Blue Heron (Ardea herodias) in a bald cypress:

Great Blue Herons are abundant here, and they can add to the magical scenes with morning fog along the river. Here’s one sitting on a bald cypress while a group of Double-crested Cormorants (Nannopterum auritum) swim by:

Another magical scene. The birds (cormorants) again add to the already beautiful scene. The fog makes the scene look like a painting:

This particular tree from the previous photo and this photo is a famous one in the park and a good photography subject during the fall. On this particular morning, I was lucky to capture this scene with a tiny amount of sunlight on the foggy scene when a Great Blue Heron flew in. This image won me an international photography contest award. It was just about being at the right place at the right time:

Sreemala was standing to my left shooting birds in flight using her telephoto lens while I was trying to get the tree with its reflection using a wide lens. She also noticed the heron flying in and captured her own version with her telephoto lens. This resulting image has its own flavor with the bird bigger in the frame, but she was unlucky to be holding the telephoto at that moment as she missed out on the reflection and the full view of the tree. It turns out that it’s really about being at the right place at the right time with the right lens!:

It’s totally possible for someone to like Sreemala’s image more, but my rule would still work as you can then say that she ended up having the “right” lens at that moment.

Oklahoma may not have the same reputation as Texas or Louisiana for the bald cypress fall colors, but we have our own nook around this corner of the state, and I absolutely cherish every trip down there.

We’re saved again, for one day, as reader Rodney Graetz from Canberra has sent in some lovely photos from a remote corner of Australia. Rodney’s captions are indented, and you can enlarge his photos by clicking on them. The three borrowed images are, I’m told, in the public domain.

Here is a series of landscape photos from a tourist boat journey along the Kimberley coastline from Darwin (Northern Territory) to Broome (Western Australia).  The distance, as the crow flies, was 1110 km (690 mi) but by hugging the coastline, the unrecorded distance was likely doubled.  We made land visits on 10 of the 12-day journey:

Our starting point, the Darwin coastline, is lapped by the Timor Sea.  It is shallow and muddy, in contrast to our Broome destination.  Like Broome, Darwin was targeted and bombed by the Japanese in February 1942.  Today, among the lush Darwin city coastline gardens, is a simple memorial honouring the 91 crew of the USS Peary, the United States Navy’s greatest loss in Australian waters.

Departing Darwin, we slowly merged with the mighty Indian Ocean whose colour and cloud streets suggested warmth, productivity and excitement.  We travelled in early June, too early to encounter the estimated 40,000 Humpback Whales travelling up from the Antarctic (June – November) to calve, nurse and then mate in these warm and safe waters  Next time!

At last, an edge of the NW corner of the Australian continent, revealing a flat and layered landscape.  The cliffs are massive, and the rock type is obviously hard because there is little sandy beach.

The Edge close up, and as predicted.  Note the tiny figures in the lower left corner.  The massive rocks are a hard Paleoproterozoic sandstone aged 1-1.9 billion years.  They are ever varied and spectacular:

Being drone-deficient, I’ve borrowed this image to illustrate this monsoonal landscape functioning.  During ‘The Wet’ (Nov–Mar), sufficient rainfall accumulates on the background plateau for a flow to eventually reach the edge and fall as spectacular waterfalls early in ‘The Dry’ ( Mar-Nov).

Downstream from the waterfalls, slow moving water combined with the incursion of plants, result in species-rich landscapes, such as this small idyllic wetland:

‘Salties’, aka Saltwater crocodile, were common neighbours at our landings.  Maneaters?  Yes, but only of the deserving at a rate of fewer than one person per year.  The ‘gaping’ is not a threat display but thermoregulation, of cooling.  Looking past the teeth, they are handsomely ornamented and coloured animals.  In the water, they are sleek!:

For geographic and celestial reasons, the tidal ranges along this coast are among the highest globally (± 10 metres).  A consequence of this, and a rocky, indented coastline, is the creation of Horizontal Waterfalls, where six times a day, huge volumes of water are forced through constricting narrows, as shown here.  Spectacular and hazardous:

The edge of a vast inshore reef (400 km², 154 sq mi) rapidly shedding water as the tide drops about 10 metres.  It is a visual and turbulent spectacle – the reef appears to rise up – and shed streams of water containing stranded fish eagerly sought by waiting birds, fish and sharks.  This one image could not capture the turbulence and action.  Details are here and an overview here:

Contemplative natural beauty of the coast was commonplace, such as here, Raft Point.  With the Dawn behind us, the red rocks and lush vegetation (including iconic Boab trees) are in contrast with the ocean, and on its horizon, small red rocky islands urge a visit:

Nearby Steep Island is another view that repays contemplation.  Why is it so?:

Journey’s end and Broome colouring contrasts with that of the previous days.  Here the rock and sands are red with an aquamarine ocean.  Tidal variation remains high.  The biological focal point is the adjacent Roebuck Bay, the background in this image:

To avoid lethal winters, some 100, 000 migratory birds fly from the Pacific low latitude coastal areas of China etc. to Australia along the East Asian-Australasian Flyway.  Roebuck Bay, a primary destination, is nationally protected as one RAMSAR wetland.  Bird lovers closely watch their comings and goings:

Finally, in the 1940s, both Darwin and Broome experienced the destructive impacts of war.  Now, in both locations, the stark remnants of those impacts remain submerged, slowly disappearing, accelerated by the living world.  That is a good thing:

In the last readers’ wildlife photo feature I have, James Blilie has appeared with some black and white photos. His captions are indented, and you can enlarge his photos by clicking on them.

Here are another set of landscape photos that I have converted to black and white for posting to a black and white Facebook group.  I am having a lot of fun having another “go” at older images in B&W.  Over the last 15 years or so, my software skills for editing photos have improved dramatically.  Since I “came from” the perspective of shooting Kodachrome slides (everything was fully captured when I pressed the shutter button), I at first resisted the idea of using photo-editing software after I switched to digital.  That was a mistake.  Editing images is critical (like editing most other works).

These are from all over and many are scanned 35mm slides or negatives.

Three images for Jasper National Park and Mount Robson Provincial Park in Canada, September 1981.  All scanned B&W negatives.

Beaver Lake on the Jacques Lake trail in Jasper National Park:

Summit Lake with figure, on the Jacques Lake trail in Jasper National Park:

Mount Robson from Berg Lake at dawn.  One of the great mountain views of the world.  I lugged the Rolleiflex and a tripod up to Berg Lake.  To be young and strong again!:

Next a photo from September 1982, also scanned B&W negative:  Taking a break from long canoeing days in the Boundary Waters Canoe Area Wilderness in far northern Minnesota:

Next, a few from my days of mountaineering in my youth, all scans from film originals:

An image I call The Thinker, taken at a camp at around 8200 feet elevation (2500m) on the south side of Mount Stuart in Washington state en  route to the summit.  1984,

Climbers on the north  ridge of Mount Adams, Washington state, with Mount Rainier in the background.  1987.  I have climbed Mount Adams, now visible outside my office window, three times, always by the more remote, less-frequented North Ridge:

Climbers on the Easton Glacier on Mount Baker, Washington state, 1989:

Next, a photo taken in Kathmandu, Nepal, 1991, scanned Kodachrome 64:

A  photo taken while backcountry skiing in Gairbaldi Provincial Park, north of Vancouver, BC, 1988:

A photo of skating tracks on the frozen pond behind our former home in Minnesota, 2013:

A photo from the Mission San Juan Capistrano, California, February 2023:

Finally, a photo taken in Seattle, in the vicinity of the Ballard Locks, March 2023:

 

Equipment:

Pentax K-1000, ME Super, and LX cameras and various Pentax M-series and A-series lenses
Rolleiflex 6cm roll film camera with Schneider 75mm f/3.5 lens that my Dad bought in Germany in 1950 and passed on to me in the 1980s
Olympus  OM-D E-M5 micro-4/3 camera and various Olympus Zuiko and Leica lenses for that system
Software:  Lightroom 5
Scanner:  Epson V500 Perfection (current model is V600, I think.  An excellent scanner.

Today’s photos of one of my favorite birds comes from Neil Dawe. Neil’s captions and IDs are indented, and you can enlarge his photos by clicking on them.

Skomer Island Puffins – Neil K Dawe

We visited a second seabird colony on our UK trip in 2025: Skomer Island off the Pembrokshire, Wales coast. Skomer Island has around 40 bird species that nest on the island but the seabirds are the big draw and the primary reason it is preserved as a National Nature Reserve. Just over a kilometre (0.67 miles) from the mainland and a 20 minute boat trip from Martin’s Haven, Skomer Island is accessible to visitors for 5 hour stays on the island where you can wander the trails and see some of the over 40,000 Atlantic Puffins (Fratercula arctica) that nest there. There are a number of other nesting seabirds there as well, most notably 350,000 Manx Shearwaters (Puffinus puffinus; Skomer Island holds the largest Manx Shearwater colony in the world), 10,000 Razorbills (Alca torda), 29,000 Common Murres or Guillemots (Uria aalge), 5,000 Lesser Black-backed Gulls (Larus fuscus), and a smaller number of other species including shorebirds, songbirds, and owls. But it’s the puffins that most people come to see.

Unlike the Bempton Cliffs, where you have to patiently search the cliffs to find a puffin, this is the scene that greets you as you walk up the trail from the boat. Scores of birds standing near their burrows, flying out to sea, or returning from the sea:

A number of trails lead past the colonies allowing excellent viewing of the birds. Perhaps the best area to view the puffins is a place called the Wick. Here, scores of puffins have honeycombed the grassy slope with their burrows, the ground sloping gently to the sea making it easy for the puffins to get airborne:

Puffins prefer burrows in the extensive open grass-herb slopes; they use the bracken (Pteridium aquilinum) areas (foreground) to a lesser extent. If they find an empty European Hare (Lepus europaeus) burrow they will readily make use of it, sometimes even sharing the burrow with the hare. Note the hare in this image. (Photo: Renate Sutherland):

Puffins nest up to and beyond the visitor footpath at the Wick, and visitors can find themselves on the path along with the puffins (Photo: Renate Sutherland):

 Standing guard amongst the bracken:

 The area around the Wick is busy with puffins flying to or returning from the sea:

Puffins practice nest maintenance throughout the nesting period; here one is bringing more nesting material to the burrow:

Puffin burrows average a metre in length and contain side chambers they use in which to defecate. Puffins at the Wick can often be seen close up at burrows near the trail:

Lesser Black-backed Gulls (Larus fuscus) station themselves near the puffin burrows and attempt to steal the puffin’s catch upon their return from the sea:

During our visit, puffin eggs were just beginning to hatch so not many adults were seen bringing food to the nest. When they do return they usually run to the burrow to avoid having any nearby gulls steal their catch. Fortunately, this bird tended to take its time. While foraging, puffins are able to catch several fish at a time that are then held against the roof of the mouth by their tongue.
