Squeaky Pete started his work week by terrorizing another roll of toilet paper. He then moved on to his ball toy before wrapping up the morning honing weaponry on the cardboard scratcher. The morning has been exhausting. Siesta time. 😴

Happy #Caturday from Squeaky Pete who decided it would be good fun to shred a roll of toilet paper.

Rob says the #BirdOfTheDay theme, is #Borbs, birds looking plump. The Alt theme is #Brown, birds with brown in their plumage. I'll take both with this Sharp-tailed Grouse #birds #nature #wildlife
A horizontal photo of a Sharp-tailed Grouse sitting in snow. The grouse takes up most of the right half of the photo and is looking to the left, sitting in profile. The grouse appears quite round. The grouse has a buffy white breast with brown chevron-like feathers. The chevron feathers are sparse near the bottom of the breast but become continuous in the upper half. The upper breast feathers have a brown V on the outer part of the feather with a buffy white center. The brown is darker brown on the margins of the V and more golden inside.

The wings are mottled with golden brown, dark brown, and white patterns. The neck and head have fine feathers, with brown and darker brown over a buffy white base. The bird's comb, an eyebrow-like patch of feathers, is bright yellow. The bird's eye is brown. Its beak is a dark grayish brown, with a downward curve of the upper beak at the tip.

The bird is surrounded by white snow and short, golden prairie grasses.

A few of the fancy sparrows have started to come through on their trip south. This juvenile White-crowned sparrow hasn’t developed the black and white striped headgear of the adults yet, but it’s still fancy! It dropped in for a quick drink, and a bath in the creek! #Birds 🪶
A juvenile White-crowned sparrow in a shallow rocky stream. The water is all black and the surrounding rooms are pink and lit by the sun. The sparrow is mottled brown with distinct brown stripes on its head. The stripes will be black on stark white when it becomes an adult. The sparrow is reflected in the black stream.

Cool new behavior caught on video! This is a special type of octopus known as a #papernautilus (aka #argonaut) and her shell is a little less than 5cm. Watch as she extends and retracts her fleshy mantle - at the end, she rapidly retracts it all! #blackwater #blackwaterdiving

The Tropical Royal Flycatcher is a bird that nests in tropical riparian zones and they have an incredible crest that can be difficult to see. They display their crests during courtship, but they also spend a lot of time preening after catching insects and they'll often throw their crest then.

Moths in a human suit (they/them) @lycomorpha.bsky.social · 22/05/2026
OK then. My birthday's coming up. So... shenanigans: I've finally let go of my last few Cryptic Cards & Insecta decks. I'm selling them at lycomorpha.etsy.com with proceeds to Medical Aid for Palestinians (map.org.uk). If you missed them up til now? Last chance!
6 different designs from an insect themed poker deck - 1 card face from each of the 4 suits, and the 2 card back designs - all featuring colourful hand-drawn insects. Details: here's what the 6 designs are. King of clubs, a big shiny blue-green female scarab beetle with white club symbols on its back. Jack of diamonds, a colourful pink cockroach nymph with very long thin antennas and red diamond symbols on its back. 10 of hearts, 10 yellow and black striped honey wasps with pointy butts that have big red hearts on. 3 of spades, 3 green and blue horned shield bugs with white spade symbols on their backs. The ruby card back design with a big ruby jewel wasp on a sunset coloured background of insect silhouettes. The opal card back design with a black and blue ground beetle on a background of blue and green insect silhouettes.Two decks of moth-themed playing cards, in their tuck boxes, held together to show the front and back tuck designs, each showing a painted moth design. Details: each of the painted moth designs shows a fictional moth species painted over a black and white polygon. Where the moths wings overlap the underlying shape, it's wing patterns match it. On the tuck back it's a hawkmoth with small black and red playing card pip markings down it's back. On the front it's a hawkmoth with a big colourful spade in the middle of it's back and wings, with intricate patterns of scenery, plants, and human eyes and hair painted in and around it.
