An incredibly 'rare find' macro. 4 different forms of lichen growing within 25 centimetres of each other.
My family has just left, had a wonderful time. Will catch up on comments over the next couple of days.
Snow Bunting - Plectrophenax Nivalis
Snow buntings are large buntings, with striking 'snowy' plumages. Males in summer have all white heads and underparts contrasting with a black mantle and wing tips. Females are a more mottled above. In autumn and winter birds develop a sandy/buff wash to their plumage and males have more mottled upperparts.
Globally, they breed around the arctic from Scandinavia to Alaska, Canada and Greenland and migrate south in winter. They are a scarce breeding species in the UK, in Scotland, making them an Amber List species. They are more widespread in winter in the north and east when residents are joined by continental birds.
They are listed under Schedule 1 of the Wildlife & Countryside Act.
The snow bunting lives in very high latitudes in the Arctic tundra. There is no apparent limit to its northern range, while the southern range is limited by the duration of daylight, which influences their reproductive activity. This species is found in the high Arctic tundra of North America, Ellesmere Island, Iceland, higher mountains of Scotland, Norway, Russia, North Greenland, Siberia, Novaya Zemlya, and Franz Josef Land. During the winter, this bird migrates to the circumglobal northern temperate zone including the south of Canada, north of the United States, north of Germany, Poland, Ukraine, and east to central Asia. During the last ice age, the snow bunting was widespread throughout continental Europe.
During the breeding period the snow bunting looks for rocky habitats in the Arctic Since the vegetation in the tundra is low growing, this bird and its nestlings are exposed to predators, and in order to ensure the survival of its offspring, the snow bunting nests in cavities in order to protect the nestlings from any threat. During this period, buntings also look for a habitat rich in vegetation such as wet sedge meadows and areas rich in dryas and lichens. In the winter, they look for open habitats such as farms and fields where they feed on seeds in the ground.
Population:
UK breeding:
60 pairs
UK wintering:
10,000-15,000 birds
The Lichen on this rock appeared plugged in with vivid colors as the sun was setting over one of the Trail Islands. There is a tiny bit of sea water frozen in the middle of the black puddle that looks to be swallowing the island beyond.
The colors were magnificent at this moment, even highlighting the grasses and coloring them orange, and then it was gone.
(012/365) Best viewed Large. I believe these to be Black Tar Lichen (which coats the rock like tar) & Orange Lichen. Found on rocks above the tideline on Baginbun beach.
( from Wikipedia)
Lichen associations may be examples of mutualism or commensalism, but the lichen relationship can be considered parasitic under circumstances where the partner can exist in nature independently of the other partner..Symbiosis in lichens is so well-balanced that lichens have been considered to be relatively self-contained miniature ecosystems in and of themselves..( better than human?)
Macro Mondays theme '' Member's Choice : Into the Woods''
Into the woods! Well, not literally… We had more than our share of rain these days and the best I could do was to take a short stroll in one of my favorite parks. Walking around, looking desperately to find something worth taking, this small lichen (perhaps 2” wide) caught my attention. It was perfectly circular and grew on an old wooden fence. It reminded me of a miniature doily. I couldn’t resist and I took the shot.
Thank you everyone for your visits, faves, and kind comments
