THE CALLS OF CURLEWS ECHOED ACROSS THE VALLEY at Ribchester today, the first birds returning from their wintering grounds nearer to the coast. There have been oystercatchers around pretty much all winter as well as a few lapwings but I always associate the return of the curlews with the first signs of spring along with Snowdrops in the church yard and the earliest bird song. Today's walk along the river to Red Bank and back produced two new birds for me here. The first was Dipper, a long awaited prospect, one flew from the river up the stream past the Roman Bath House first thing. I know they have been see further up this stream but this is the first time I have seen one by the river. The second was a Greylag Goose, flying west down the valley (before today I had seen more Greenland White-fronts here than Greylags!). A Green Woodpecker calling loudly at Red Bank was probably a visitor from the woods at Hothersall Hall, where they are more regular.  Oystercatchers have increased to 32 on the meadow by the river opposite Red Bank and other signs of spring were birds, which are now singing including Chaffinch, Dunnock and Wren. A pair of Great Spotted Woodpeckers was in the wood at Red Bank, where the male was drumming. The morning's total was a very respectable 56 species, only 3 off my highest total and although some trickier birds like goldeneye, sparrowhawl and skylark put in an appearance other regulars like kestrel, Little Egret and kingfisher were missing.
