Swifts this Weekend

Swifts for this Weekend
KEEP LOOKING!
Please keep looking for Swifts this weekend, any counts of numbers at colonies or congregations where ever, very welcome as well as counts / directions of moving birds showing a prominent movement direction in relation to the time you count for. See if the direction of any prominent movement is into the wind? We want to confirm whether the birds moved off because of the weather to come (Thursday here) – if so they will come back now conditions are improved. Or, whether they have left to move off back south and away, in which case comparative numbers where you count will be much reduced. Swifts will due to the time of year be moving off and away now in any case and being ariel feeders, it is possible that the weather may have hurried them along.

Also any counts of Swallows / Sand Martins moving, where ever, and showing directional prominence very welcome. The older juveniles are now moving off and away.
Dave.
