This morning's hike. A fogbow was trying to form, but the fog was on the sparse side. Hard to see is the moon above it (aligned with the electrical tower). #ECK #Scape #Hiking #Fogbow #Weather #WestCoastKin
A subtle pale white arch has formed over a large space and valley. The thickness of the fog bow is  a bit uneven, but it does show up against a blue sky. Below it is more ground fog on the field, (Laguna Lake Open Space). Underneath the fogbow's center is an electrical tower. Directly above the tower is the fogbow, then the moon (very small). The field is dark umber brown.

Some moments remind you why you love photography. It’s not just about the shot, it’s about being there, feeling the wild, and learning from Mother Nature. I’m already excited to get back to Africa in 2027. Can’t wait to see what Mother Nature has waiting for me. #wildlife #safari #africa

Full-body visual record of a Great Egret (Ardea alba) in flight. The bird is captured in a dynamic horizontal profile with fully extended wings and brilliant white plumage. Background consists of a blue sky with scattered clouds. Extreme telephoto perspective (up to 600mm) emphasizing the intricate detail of the feathers and the avian form against the open atmosphere. Optimized for ornithology and avian flight dynamics indexing.

Happy #Stunday! The view from the top of the Tromso cable car in Norway was definitely stunning. #EastCoastKin #ECK #PhotographersUnited #photography #ArtYear
A stunning scene of the small Arctic city of Tromso, Norway, taken from a mountain. There are snow-covered mountains in the distance, then a strip of blue water, then a long strip of city with a cruise ship docked, more deep blue water with a bridge on the right, and a strip of land with some buildings on the bottom. The sky is darker blue at the top, getting lighter toward the mountains with a few puffs of clouds right above the mountains.

Hi folks, sorry I’m late. Hectic day. Going to go through as many #BirdOfTheDay entries as possible. I Love Egret splashes. #birds #photography #ECK #ReflectionsAndShadows
A Little Egret stands in shallow water, dipping its black bill into the surface as a splash of droplets rises around its head. Its white plumage contrasts with the deep blue water, while its dark legs and striking reflection are visible below. Ripples spread across the water, creating a beautifully atmospheric scene.

Good morning birders and buddies. The #BirdOfTheDay theme today: #RecentGardenBirds, most recent capture/s of a bird/s in your garden. Alt #ReflectionsAndShadows, any capture of a bird with an accompanying reflection/ shadow. Song Thrush in my garden, few days ago. #birds #photography #ECK
A Song Thrush perched upright on a diagonal branch, its long tail extending downward. The bird has warm brown upperparts and a pale cream breast densely marked with bold, dark spots. Its dark eye and pointed bill are sharply defined, while a slender twig and small green leaves partially cross its body. The background is filled with softly blurred green foliage and reddish berry clusters, creating a natural woodland setting.

Today's #BirdOfTheDay is #RecentGardenBirds. Although not exactly recent, this juvenile Red-shouldered Hawk (Buteo lineatus) is one of the most interesting birds I've seen in my yard. The bird attacked a toy in the neighbor's yard and wound up with red fake hair in its talons. Not happy. #birds

NOAA launches the weather balloons, floats the ocean buoys, flies the satellites, and staffs the forecasters that tell us when storms are coming. That data supports about two-thirds of the economy, roughly $1.3 trillion a year, and it paid us back $73 for every dollar we spent on it.

Gary Grey Heron standing in the bush looking up to see what's making a lot of noise, but it was only Freddie Fulmar with his siren blaring away as he was chasing Percy Puffin for speeding.
Gary wasn't happy about all the noise because it woke him up from his afternoon nap, and he knew that was his sleep over with and he hates waking up before his alarm goes off.
The paparazzi did tell him to grow up which made him even angrier, but there was nothing he could do about it.

Captured at WWT London Wetlands.Rachel Raven was surveying her patch from high in the bush, but there wasn't much around apart from the stalker with a camera.
When she heard the paparazzi shout up, "who are you calling a stalker", and her reply was "well you are hiding in a bush following me", and there wasn't anything the paparazzi could reply with.
The moral of the story is don't annoy the females 😂

Captured at WWT London Wetlands.Kamala Kestrel was out looking for food for her hungry brood, when she spotted some of the Little Terns chicks moving around below her. This is something the young ones were told not to do as it's very dangerous for them, but sadly for the little chicks they didn't stand a chance when Kamala swooped down and grabbed one of them while shouting "I'll be back". This was something she picked up from watching her favourite film series "Terminator", even though she was nowhere near his size although she was as lethal.

Captured at Long Nanny Tern Colony.Rocky Red Kite was out on the prowl, although he wasn't having much luck when the paparazzi spotted him drifting on the thermals.
And every time he circled around, the smaller birds took off in fright then circled around before landing when the coast was clear.
But it wasn't long before Freddie Fulmar was on the scene to clear the scavengers away, making it much safer for the smaller birds to relax.

Captured at Summer Leys Nature Reserve.

A purple passionfruit flower has three clublike stigmas above five anthers and dozens of bright purple filaments with curly tips radiating out from a white pinwheel center. Underneath are a dozen pale purple, concave petals and a bunch of three-tipped green leaves shaped like theropod tracks.
