Meadow Pipits get going

Heysham Obs
Interesting Twite statistics.  35 were caught yesterday, two lots of 20 were caught today.  Only 10 of the 40 caught today were not caught yesterday and 7 of the first lot of 20 were retrapped in the second lot.  Yet the grand total of Twite in the last two days has been c82 yesterday and c75 today with just 5-6 unringed/day.  These probably accounted for the 5 unringed birds caught in the last two days.  Conclusion being that there is a 'core' of habituated birds, a handful of unringed birds unfamiliar with whoosh nets and a gang of wary ones!  Permission granted to use in Key Stage ?5 maths.  60-70 were back on the seed by lunchtime

Meadow Pipit and Kittiwakes were on the move today with three very short seawatches producing the latter and there may have been many others
