hodie breviter ningit, itaque Silvius foris festinat et traheam novam experitur. (Today it's snowing for a little while, so Silvius hurries outside and tries out his new sledge). carpe nivem! (Seize the snow!)

Photo of Silvius, the little Latin mouse, sitting on a red-painted wooden sledge in the snow. He's wearing his paenula (hooded cloak) with a red leather belt to keep it closed against the cold. Silvius has been waiting weeks for the rain to stop, and he made the most of the short snowfall!

Apparently it's #WorldHippoDay! 🦛🦛

Let's celebrate with this #Egyptian carving of a Hippo, made 5.000 years ago from calcite.

Hippopotami were associated with life, regeneration, and rebirth.

On display at Ny Carlsberg Glyptotek

Next for #SuperbOwlSunday I have this group of 3 Snowy Owls (Bubo scandiacus) preparing for an evening hunting flight at Boundary Bay in Delta, British Columbia, Canada.

These 3 always look to me like they are up to no good. 😆

A few more of these owls here: mrussellphotography.com/blog/b

My nomination for today's .

The Cosmic Owl is two galaxies that crashed into each other, creating overlapping ring-shaped splashes of stars. It measures 150,000 light years from side to side, or about 10^20 times the size of a Great Grey Owl on Earth.

Sitting on the ground, it winks.
It is happy here.Up in a great tree
A great horned owl, it sees us
And it doesn't care.

Here's my most photo to celeberate this special day! A spotted owlet looking a bit suspicious of our intentions.

Taken in 2015 in North-Western , I only witnessed this beauty thanks to our guide and her team of motorcycle-spotters.

“Guess what day it is!!?? The greatest day of the year… Superb Owl Day! 🦉

A day dedicated to admiring owl photos and pretending nothing else important is happening.

Oh wait … it’s also the Super Bowl.

But let’s be honest — Superb Owl Day is clearly the more important event.” - Nicole Seward

Another very superb owl: I was standing on a path next to a marsh when a bird from down the way started flying towards me. As I stood transfixed, the barred owl landed on a branch of a tree just on the other side of the path!!! This isn't my best barred owl shot, but it was my first one. :)

A barred owl (big black eyes; orange beak; grey, white and brown feather colouring) is sitting on a branch facing left but looking to our right.

People are posting #SuperbOwl photos for #SuperbOwlSunday, so I thought I'd add mine to the mix. For the longest time, I had wanted to photograph an owl, but I had been thwarted by their stealthiness. Then, I spotted one hanging out by a trail near my house.

It didn't seem perturbed by the resulting photo session.

A spotted owl of some kind sits in the crook of a tree branch. As it preens itself, it glances at the camera in a bit of a squinty look. In the background, fall colours on blurred leaves.

This superb owl was sitting on a branch only about a foot above the ground.

A brown and white owl with long "ear" feathers and a rusty brown face and golden eyes is sitting on a branch, back towards us but looking right so we can see its face and a baleful eye keeping an eye on us.

For the yearly #SuperbOwlSunday theme I have this Snowy Owl (Bubo scandiacus) hopping onto a piece of driftwood at Boundary Bay in Delta, British Columbia, Canada.

#Wildlife #BritishColumbia #SuperbOwl

A snowy owl (mostly white with some black) has its wings and legs out stretched as it lands on a piece of driftwood in an intertidal marshy area. The grasses in the marsh behind it are a very warm colour with the sunset sunlight shining on them.
