Sorry, no pretty loon pictures or sound files this time.
In another place, I'm doing a thread of islands I've visited, because it fits my username. One photo every day or so. But sometimes an extra photo slips in that I can't use (because one photo per island) so I'll have to share it here.
St Tredwell's Loch, on Papa Westray, one of the smaller islands of Orkney. I don't know why a lake on an island seems so odd, but it does. Maybe because of how close it is to the sea. (You might be able to see the strip of blue sea behind the loch.)
Photo is taken from St Tredwell's Chapel, the ruins of a Medieval chapel built over Iron Age remains, or an overgrown bunch of rocks on a hill. (As you can in the foreground.)
If you're into photos of islands, the thread starts here:

A peaceful Sunday sky to wrap up the weekend?
Hope you found a little time to pause and enjoy the moment?

Climate warming and heatwaves accelerate global lake deoxygenation, study reveals
https://www.eurekalert.org/news-releases/1077716
Long-term climate warming and the increasing frequency and intensity of short-term heatwaves are significantly reducing surface dissolved oxygen (DO) levels in lakes worldwide, according to a new study published in Science Advances.

Lakes change color based on how healthy they are, their colors reflecting the ongoing physical and biochemical processes.
• Blue lakes are primarily located in northern latitudes.
• Green lakes are more prevalent in densely populated mid-latitude regions such as southern Europe.
• Reddish and yellowish lakes are mainly in the Southern Hemisphere.
"However, significant changes in lake color can signal ecological disturbances."

I am happy to be part of this conference. My involvement is hands on so visit me at my site, learn about loon surveys and other birding opportunities, see what is on the lake.

I arrive in predawn darkness to venture into the Fernhill Wetlands preserve. My eyes glance upward to the nighttime sky already graying in the east. The moon pushes night toward the western horizon, fleeing the advent of morning light. My ears catch the dim hum of traffic hanging at the edges of quiet.

It has been months and months of overcast, grey drizzle. At least, it has felt that way. When the sky cleared, it was usually while I was at work. This weekend, things finally fell in place. The forecast promised sun and spring warmth, and I didn't have to work.
I loaded up the car, and set off half past five in the morning, which is inhumanely early for a nightowl such as myself, but I wanted to catch the sunrise and I had a ways to go before reaching the Seven Year Lakes in Frederikshåb Plantage.
The Seven-Year Lakes got their name because they are not always there. The lakes appear and disappear with the height of the groundwater. The groundwater table has its own "hills and valleys", and therefore the Seven-Year Lakes are quite unpredictable.
Frederiks Hopeless Plantation was the name of the forest by the locals for many decades, because it took almost 100 years to turn a small piece of Randbøl Hede into a forest. The idea was to stop the sand drift. In the 1600s most of the forests in Denmark had been felled and the agricultural land was overused. Frederikshåb Plantation is an example of the fight against sand drift. Work started in 1804, when Scots pine and birch were sown. Dikes were built, which created a bit of shelter for the plants. Growing conditions were harsh with sand drift, frost, drought and pests. Today it's a beautiful and varied forest with a relatively rich wildlife.
