There is a large flock of farmland birds at TQ 025 925 which can be accessed from the footpath of Chalfont Lane. The reason being there is more exposed soil due to the M25 widening as there are various spoil heaps in the field. Impressively there is a flock of at least 90 YELLOWHAMMERS - the largest flock I can personally recall seeing locally. I also had a single BRAMBLING here amongst a flock of Chaffinch and Linnet . 150 Wood Pigeon and 70 Jackdaw flew over as I arrived at the start of the footpath. A few Skylark were noted as well.
Meanwhile, on the county border of the River Colne, the SIBERIAN CHIFFCHAFF is still present just north of Broadwater Sailing Club (per Joan Thompson)
Elsewhere, 2 JACK SNIPE remain at East Hyde, and 3 SMEW at Stockers Lake and up to 5 at Amwell NR. Two BITTERNS remain at the latter site also.
