Dipper - Cinclus Cinclus
aka Water Ouzel
Dippers are members of the genus Cinclus in the bird family Cinclidae, named for their bobbing or dipping movements. They are unique among passerines for their ability to dive and swim underwater.
They have a characteristic bobbing motion when perched beside the water, giving them their name. While under water, they are covered by a thin, silvery film of air, due to small bubbles being trapped on the surface of the plumage.
Dippers are found in suitable freshwater habitats in the highlands of the Americas, Europe and Asia. In Africa they are only found in the Atlas Mountains of Morocco. They inhabit the banks of fast-moving upland rivers with cold, clear waters, though, outside the breeding season, they may visit lake shores and sea coasts.
The high haemoglobin concentration in their blood gives them a capacity to store oxygen greater than that of other birds, allowing them to remain underwater for thirty seconds or more, whilst their basal metabolic rate is approximately one-third slower than typical terrestrial passerines of similar mass. One small population wintering at a hot spring in Suntar-Khayata Mountains of Siberia feeds underwater when air temperatures drop below −55 °C (−67 °F).
Dippers are completely dependent on fast-flowing rivers with clear water, accessible food and secure nest-sites. They may be threatened by anything that affects these needs such as water pollution, acidification and turbidity caused by erosion. River regulation through the creation of dams and reservoirs, as well as channelization, can degrade and destroy dipper habitat.
Dippers are also sometimes hunted or otherwise persecuted by humans for various reasons. The Cyprus race of the white-throated dipper is extinct. In the Atlas Mountains dippers are claimed to have aphrodisiacal properties. In parts of Scotland and Germany, until the beginning of the 20th century, bounties were paid for killing dippers because of a misguided perception that they were detrimental to fish stocks through predation on the eggs and fry of salmonids.

Thank you for your kind visit. Have a wonderful and beautiful day! ❤️❤️❤️
Todays weather has been absolutely dreadful, a day off work and zero opportunity to shoot anything, extremely low cloud and rain all day. Then this evening came and the rain stopped and for once the low cloud ad light pollution worked in my favour. I think so anyway. This was shot at Largs yacht Haven in North Ayrshire, Scotland.

Thank you for your kind visit. Have a wonderful and beautiful day! xo💜💜
It looks really pretty, BUT it is pollution. There is the street overflow. So after rain there is alot of debris. There is an inbetween station thats collects bottle sticks whatever before it travel to next pond. There are several of these collect basins before it ends up in Lake Ontario. This is the 1st collect basin. The blue colour is reflection a blue grafitti. I have no clue what debris was but it was very thick cream like gathering around the stick. I was very hard to focus on. Good manul focus practise. Straight from camera.

Three otters were photographed while playing along the banks of a river in the park. It had been snowing earlier in the day. The temperature was between 28 to 34 degrees.
The North American river otter (Lontra canadensis), also known as the northern river otter or the common otter, is a semiaquatic mammal endemic to the North American continent found in and along its waterways and coasts. The river otter is protected and insulated by a thick, water-repellent coat of fur.
The river otter, a member of the subfamily Lutrinae in the weasel family (Mustelidae), is equally versatile in the water and on land. It establishes a burrow close to the water's edge in river, lake, swamp, coastal shoreline, tidal flat, or estuary ecosystems.
North American river otters, like most predators, prey upon the most readily accessible species. Fish is a favored food among the otters, but they also consume various amphibians (such as salamanders and frogs), freshwater clams, mussels, snails, small turtles and crayfish.
The range of the North American river otter has been significantly reduced by habitat loss, beginning with the European colonization of North America. In some regions, though, their population is controlled to allow the trapping and harvesting of otters for their pelts. River otters are very susceptible to the effects of environmental pollution, which is a likely factor in the continued decline of their numbers. Several reintroduction projects have been initiated to help stabilize the reduction in the overall population. – Wikipedia

The dew pond from South Downs Way between J&J Windmills and Ditchling Beacon. This was taken about 2 hours after sunset. The yellow tinge in the sky is from the AmEx stadium, the artificial lighting helping to condition the pitch there. The orange tinge on the right comes from the light pollution from Brighton and Hove
