Volcanic Glass: What Happens When Lava Meets Ice?

Pecking order.....

Observing birds feeding close to a window allows for scrutiny of their behaviour and it is always interesting to see how some species or individuals become dominant or begin to adapt their feeding styles by copying others. Goldfinches are noisy, pugnacious feeders but despite a threat the individual in this short clip soon gives way to the larger male chaffinch. In my experience, chaffinches regularly use seed dispensers but this is the first time I have seen one using a niger seed dispenser.

Harvest mouse......

Harvest mice are much rarer than they once were.....they build their nests amongst the stems of long grass or cereals and can be found in areas of grassy scrub. They have suffered heavily from habitat loss and changes to farming practices They are visibly smaller than wood mice, with a blunter nose and smaller ears. This one was filmed in Norfolk at the Wildflower Centre near Holt, tucking into a bowl of millet.

Where has the road gone?...Crossing the Washes at Welney......

Many years ago I took my elderly neighbour to see the Whooper and Bewick swans at Welney and after a drive of over a hundred miles got to within a couple of miles of the place to be confronted by this road. The options were simple. Turn back. Take a detour of a further twenty five miles. Or go through it. At the time I owned a Ford Maverick 4WD which, although not a Land Rover, was quite capable and had very high ground clearance. The water wasn't quite as deep as it is in this video but it is unnerving when all you can see of the road are the height markers and you find yourself trying to avoid ducks. We did make it and I have to say this video brought the memories flooding back. Sorry.........
