North east winds and low cloud finally replaced the high pressure conditions and immediately the migrants have become evident (instead of migrating out of sight at height). Today we had 3 Swallows, 2 Sand Martin, 2 Willow Warblers, 1 Common Buzzard, 6 Fieldfare and an increase in Blackcap and Chiffchaffs. Highlight of the day was 2 Avocets which dropped onto the lake for a few minutes. Also a Jack Snipe. A big day tomorrow- the first day for our new ringing group!
