visited my club water today - completely different to this time last year - hardly any green growth on tree's and the lilypads are hardly showing at all whereas last year at Easter , they were quite profuse. Late start this year i think
I can never tell the difference between swifts and swallows.
I know they tagged one of them and found that they fly six miles up at night, then go to sleep on the wing.
They fly down in a spiral, whilst a sleep, incredible, or what?
Swifts cannot perch by the way, however they can hang, similar to a bat. They are the fastest flying bird in the world and have been known to reach 100 mph.
I have seen swifts tackle 4 inch long locusts and 2 inch long wood wasps which have a tremendous sting. They eat vast numbers of insects.
