This is GRIZZLY 399. She's commonly known as the QUEEN of the TETONS. She's 24 years old! A very old lady in bear years. This spring she emerged from her den with quadruplets, which is incredibly rare. Yesterday I had the pleasure of photographing mom & her sweet cubs. It was such a thrill for me! If I'm lucky, I hope to run into this 'royal family' again. It would be wonderful to see the cubs grow up over the next two years. Long live the QUEEN! 👑

The big four Suntec City Office Towers and will be the last image on this location… I promise…:) This is not a photoshop mirror image.

Yesterday night was the night for the first light with my new telescope.

I tried 4 different targets to see if the stars are round ect.

I need to say I am very very happy with the scope.

Grand Teton National Park - Note the smaller cub off to the right. It was a real challenge during trip to get all four together as this smaller runt of the litter was always falling behind and left out of the play. I hope he makes it.

Apparently armadillos have limited vision but very keen sense of smell. And they have sharp claws which can dig well, but we saw four of them rooting around with their noses, somewhat pig-like. While armadillos are often considered nocturnal, especially in summer, we saw these in mid-day. They had come out from under a raised structure. Since we saw four together, it was interesting to learn that a single fertilized egg gives rise to four separate embryos, such that each litter consists of four identical quadruplets.

 

We did not expect to see armadillos, even after we had seen several dead ones along roads. Apparently their range has gradually expanded north and northeast and we were near the current edge of that expansion. (This expansion has been going on for many years, at least since 1840 when they were first noted north of the Rio Grande along Texas and Mexico.)

On the Last Day of our Trip we finally caught up to the Beautiful Mother Grizzly #399 and her 4 cubs, The History of #399 is definitely a intriguing one and one that is paving the way for the species here in America and staying Protected, at 26 years old she’s had Several Litters of cubs with around 17 descendants with many that have died, and now currently with her 2yr old Quadruplets which will probably be her Last given her age.-She’s a Smart Bear and is showing her skills to the cubs so that they can survive this rugged part of the country.

 

I couldn’t have asked for a Better Time in this Beautiful National park, It’s been Long overdue with my Last trip being 10yrs ago, Think it’s Time to pickup a Nice Super Telephoto Lens and get out here at Least once a year! 👍

The lion brothers Bandele and Batou running to their food which is served on one of the little rocks in their outdoor enclosure. Each of them was treated with a huge meat portion.

>>>>> They were born 2011 in #TierparkHagenbeck (Hamburg) as quadruplet together with their is sisters Naledi and Sakina.

Bandele & Batou moved to #TierparkHellabrunn (Munich ZOO) in 2012 – their two sisters moved to two different zoos in Sri Lanka.

Robins nested under my second story deck this summer and made a heck of a mess. The mother robin was not happy with me whenever I mowed the lawn or tried to use our picnic table. This photo was taken just a day before the first one left the nest. I hope he got better looking when he grew up.

A quadruplet of BNSF units haul an empty coal train eastward on the MRL 3rd Sub just east of Clinton on the sunny afternoon of April 15, 2025.

This youngster was 16 months old when I took this photo. He was born in January or February, while his mother was sleeping in her winter den.

 

When grizzly cubs are born, they are blind, hairless and toothless. Of all mammals, bears at birth are the smallest percentage of their adult size. The cubs weigh 500 grams (1 pound) or less at birth. Their mother's milk is one of the richest in nutrients and fat in all of nature though, enabling the babies to grow to a size where they can survive in the outside world when their mother leaves the den in April.

 

Cubs stay close to their mother and they learn all of their survival lessons from her over their first 2-1/2 years (some areas report cubs staying with their mothers for an additional year). Bear cubs are most frequently twins or triplets, with quadruplets and single cubs being less common.

 

At 16 months old, the cubs are eating more and more solid food and rely less on their mother's milk. They spend most of their time exploring the world within a hundred metres of their mother and wrestling with each other. At this age, they are excellent tree climbers, which they do to avoid danger.

 

This youngster is about the size of a large dog and looks friendly and huggable. However, he already has powerful claws and teeth and his omnipresent mother, nature's ultimate protector!

A pair of freight engines on a Norfolk Southern OCS was a routine thing 15 years ago. Back in a time before NS had purchased a quadruplet of F-units specifically for the purpose under Wick Moorman's leadership.

 

On this particular OCS (Office Car Special) the Southern "heritage unit" and another freight locomotive were given a spa day and tapped for the job.

 

Seen here passing the old train station on the former Southern Railway's DC to Atlanta Mainline in Culpeper, Virginia.

Just after half moon with good seeing means: Rupes Recta time. The Rupes Recta is not a cliff, as had long been thought, but a more than 100 km long escarpment that is marked by a slope of around 10 degrees extending over a few kilometres of width.

 

Just after waxing half moon, the slope of the Rupes Recta is in the shade, while the surrounding landscape in the Mare Nubium is already bathed in the local morning night. Conversely, right before waning half moon, the Rupes recta will be seen as a white line against the dusy surroundings.

 

It doesn't come out so well in this shot, but I also gazed at the moon a lot tonight using short focal length eyepieces (leading to large magnification) and the Rupes Recta looked like a sharp gash in the lunar surface.

“When photographing women, we have three paths: photograph them with the "male gaze” ; photograph them as "photographer eyes” and photograph them as "poet feeling”. I always try to be the three ...” by Old Roger

Apologies for a subject that's too far away to photograph well. There are 3 nests I can clearly see- two with twins, and this one with quadruplets. All are looking close to fledging, and it's a good thing too. The new owners of this property have had heavy equipment mucking around in their large front yard. I have no idea what they're up to, but when activity like that is going on, the herons are clearly disturbed. I fear for the future of this rookery site.
