Goldfinches and sunflowers on the Durham coast

Earlier this month, the largest flock of goldfinches that I've ever seen congregated on the Durham coast. There must have been well over 200 birds, feeding on seeds of the limestone flora on the cliff top above Blast beach. Most seemed to be eating meadowsweet seeds, but there was also a large store of knapweed and hemp agrimony seeds for them to feed on. Many of the birds hadn't moulted into full adult plumage yet and were quite hard to spot on the ground, but when they all took to the air at once they were a magnificent spectacle.   

Further along the coastal path, near Hawthorn dene, two fields have been sown with a wild bird food crop, including fodder radish, quinoa (below) and sunflowers which will provide food for finches and buntings later in the winter, when the supply of wild flower seeds runs low. Last winter similar crops attracted large flocks of linnets.

Orchids on the Durham coast

Durham's magnesian limestone grassland is famous for its orchids. Yesterday, when we were walking along the coast near Hawthorn Dene there was a sensational display, in the hay meadow at the mouth of the dene itself and even more so in the thin soils around the old quarry. 

There were many hundreds of spotted orchids and scores of pyramidal and fragrant orchids. There were also plenty of twayblades, but it's hard to estimate their numbers because their green colour makes them easy to overlook. 

I think this was the best orchid display that I can remember here.

This is the area around the quarry with the highest density of orchids, growing in a thin veneer of soil over limestone. Other species in flower here included centaury and yellow-wort, greater knapweed and carpets of bird's-foot trefoil.
