Good bit of vis mig along the barrage and over the bay this morning 9-11am: Swallow 865, Siskin 54, Grey Wagtail 26 and Tree Pipit 4. I’m sure there were quite a few Sand and House Martin moving too but impossible to judge as there are still lots of the local breeders knocking around over the bay to confuse the issue. Most of the Swallows went through in less than an hour between 10-11.
