Warthog piglet

During our Birds and Wildlife Safari in Uganda in September there were lots of young animals around…calves and fawns, cubs and piglets. This is Warthog Piglet at Lake Mburo National Park…not newborn, as they only weigh 1 to 2 pounds at birth…but maybe a few weeks old. This is perhaps as cute as a warthog gets (unless, of course, it is a Disney warthog). Sony Rx10iv at 1200mm equivalent. Program mode with my custom birds and wildlife modifications.

Petas Monkey

Our third (out of 9) primate species on my September #Epic_Uganda_Vacations birds and wildlife safari in Uganda’s National Parks and Reserves. This fellow is in Murchinson Falls National Park. He climbed up to greet the first rays of the rising sun (and maybe to keep a better eye on us as we stopped on the road near him). They are more commonly seen foraging on the ground, and, indeed, that is where we saw our first one. This one presented itself a half hour later and further into the drive. Given their common social structure…they live and forage in troops of up to 25…there were probably a lot more of them out of sight in the long grasses under the acacia trees below.

The heavy brow and the dark eye-sockets make the eyes hard to recover but you can see a hint of them in the closer view. 🙂


We did not have any close views of wolves in Yellowstone. They were always well away, often across the river. This is a classic Yellowstone shot. American Bison holding down the top right, two Pronghorns crossing left, and a wolf in the foreground crossing right. They are all aware of each other, but not concerned, at least at the moment. Sony RX10iv at at least 600mm optical, and probably some Clear Image Zoom above that. Program mode with my custom birds and wildlife modifications. Processed in Polarr.


After digiscoping more American Bison than you could shake a spotting scope at, we spent most of an afternoon looking for a Pronghorn at a reasonable distance for good digiscoping. One of our participants spotted this one on a little rise of ground above the road, right near a pull-out where the bus could park, and we all piled out with our scopes. The Pronghorn proceeded to amble down the hill toward us, and got as close as the legal limit of 25 yards. Any closer and, according to park rules, we would have had to back up. We had lots of time to take as many digiscoped images as we wanted before it turned and wandered back up the hill.

Despite their superficial similarity (and their other common names) Pronghorns are not antipopes. They are the last members of an otherwise extinct family of North American mammals, more closely related to Giraffes and Okapi, than to deer and old world antelopes. They are generally considered the second fastest land mammals, just behind the cheetah, and could, in theory, out last a cheetah over a mile chase. They are way faster than any existing North American predator.

The good life… Sea Lion style.

Sea Lions are the original bathing beauties…and they spend a good deal of their lives sun bathing on the rocks. Living the good life in Southern California. These beauties are at La Jolla Cove north of San Diego. Sony RX10iv at 600mm equivalent. Program mode with my custom birds in flight and action modifications. 1/1000th @ f4 @ ISO 160.

Dusky-footed Woodrat, San Diego

Sally, my daughter, and I found a couple of Dusky-footed Woodrats uncharacteristically out and about in daylight, feeding on flower petals along the path in Tecolote Canyon Nature Park in San Diego, California. She almost stepped on one right at the trail-edge while looking at birds. I managed to get this shot through the thick foliage. I know. It’s a rat, and many people have a thing about rats…but it is one of our few native rats, and an interesting creature. It builds large domed nests of sticks and litter (and sometimes adds a tree loft in a nearby tree), often in villages or hamlets of a dozen or more nests (perhaps the origin of its common name, Pack-rat, though it is a solitary creature in all other ways), stores food, builds a separate “toilet” faculty away from the nest, has soft fur and furry tail. I find it appealingly cute…certainly as cute as any gerbil or hamster. 🙂 Sony RX10iv at 600mm equivalent. Program mode with my custom birds and wildlife modifications. 1/250th @ f4 @ ISO 500.

Seal bonding…

A mother and a new-born Harbor Seal recognize each other by the unique smell of each other’s breath…but it has to be learned and you can observe mother and child nose to nose soon after birth and repeatedly over the first few hours of life exchanging breaths. Later, when the pups are in the water and crying for their mothers, you will see adults approach the pup and check the breath to see if it is theirs. Adult females can be quite aggressive when approached by a pup that does not have the right smell. I always enjoy these nose to nose shots. This was taken on the outside of the seawall at the Children’s Pool in La Jolla Cove, in La Jolla, California. Sony RX10iv at 600mm equivalent.

Sea Lions

At the other end of La Jolla Cove from Children’s Pool and the pupping Harbor Seals, there is a good sized colony of Sea Lions. This group of adolescents was having a mild altercation over the occupation of some rocks above the shoreline. It is rare to see an adult sea lion without scars…so these confrontations do get more violent as the sea lions mature. La Jolla Cove, California. Sony RX10iv at 600mm equivalent.

Three-fingered Sloth, Mother and child

I posted a gallery of shots of the male Three-fingered Sloth taken at Cope’s home in La Union, Costa Rica a few days ago. This is the female with her child, from our visit the week before. Always something fascinating at Cope’s. Again, the sloth was so close the photos were taken at 120-140mm equivalent (except for the close up of the face, which was at 600mm equivalent). And again, it was very dark under the heavy canopy so these were all taken in Anti-motion Blur mode. Notice how green the fur of the female sloth is…that is, of course, algae growing in the fur. We were close enough to see the moths that feed on the algae. I am calling this a Three-fingered Sloth in line with the new naming convention, instead of the more traditional Three-toed Sloth, since, again, both tree sloths of Central and South America have three toes on each hind foot.

Three-fingered Sloth

Every visit with Cope, a self-taught artist and naturalist in the small village of Flores near Gaupiles, in the Limon provence of Costa Rica is a rare treat. He knows where the owls and Potoos and bats of the area are roosting, and the little sanctuary he has created around his home is always teaming with an unbelievable number of interesting creatures, from Helmited Iguanas and Wood-rails to many varieties of hummingbirds. This December he had a family of Three-fingered Sloths living in his heavily vegetated yard…a male and a female with a young baby. On the first of my two visits we got to see the female and baby, close enough so we could have touched them, moving along a branch near Cope’s little stream. This sloth has been called “Three-toed” in most references and by most people for years, but there is a movement now to change the common name to “Three-fingered”. Both Central Amercain tree sloths (not, by the way, closely related at all) have three toes on each hind foot. The difference is in the hands and number of fingers. As you can see in the photos above, this sloth has three fingers on each forefoot. On the second visit we were just getting out of bus after a successful search for Specticaled and Crested Owls (and tent-making bats) when Cope called us urgently to come see. The male sloth was moving in the vegetation above a narrow trail, crossing from one side to the other. It is very dark under the low heavy canopy Cope as created. I had learned my lesson on my first visit and brought a flashlight this time, so I was able to illuminate and photograph the sloth without disturbing it. We watched it for 15 minutes or more, as it made its slow way across. Like an accrobat in slow motion on the rings and ropes, it used the vines and branches to preform a series of moves somewhere between yoga poses and styalized dance just a few feet above our heads. Totally fascinating. We could only stand and watch in wonder. Sony RX10iv at various focal lengths…the close up is at 400mm equivalent from about 6 feet. LED flashlight for illumination.
