Notes: We were forced to abort the first attempt at CES visit 9 on Sunday (26th) when heavy rain started at 08:00hrs halfway through the session at which point 33 had been captured. It is a little disappointing that when we were able to do a full visit we captured 31. Potentially, had we been able to complete last Sundays session, we would have captured 50+. 31 is below the average of 47 for visit 9; range 2013-24 to 1998-87. It looks like many birds left during July’s rainy season! Have put Sundays visit as additional and will leave it to the BTO to sort out which visit gives the truest result. I even managed to get the plank across the gap unaided and without falling in thanks to the magic gloves.

Sightings 38 Species: Good flock of 20+ swifts feeding high over towards Thatcham, quite a few terns flying about and 50+ Canada goose flying about having completed their moult.
