Stackpole - steady movements of migrants

Whimbrels have been passing along the Castlemartin Coast (stopping of at Stackpole each day for the last few days - quite typical at this time of year). Largest flock so far this week was of 15. Three common sandpipers on the lake shore yesterday and a noticeable influx of willow warblers late in the week.

On the lakes still 2 pairs of gadwall and the single female goosander present. Whitethroats already nest-building and chiffchaffs now feeding young in the nest - it doesn't take long for these new arrivals to get established!

Noticeable lack of stonechats around - last years 5 occupied territories at Stackpole has so far been reduced to 2. They still may arrive of course but is this due to the sub-zero temps back in winter?
