6/4/10: Waterlow Park birds (Highgate, London Borough of Camden)

A fairly formal park, with some wilder areas and three lakes. Checked out the Middle and Lower Lakes. 10 Canada Geese, 14 Tufted Duck, 3 Moorhen, 3 Coot. Some Mallard, one male 'hanging out'with a pure white, while this 'harlequin' of a hybrid (apologies for picture quality ....) was nearby:

A Wren was seen in the undergrowth.

On the way back to a tube station, there were 12 Greater Celandine in wall/pavement crevices around the junction of Oakford Rd and Lady Somerset Rd, Tufnell Park, with a single Wall Lettuce (Mycelis muralis) and some Hart's-tongue Fern in the front garden on the latter street. Wall Lettuce was common around my old Bristol haunts, but I have only found a handful of locations for it in London so far.
