Nature notes:


First lawn cut here first week (last year it was late Feb the earliest).

c 11th likely Chiffchaff heard towards Slough from AG, it was windy so not certain and only briefly heard the one day (on passage?)

Fri 13th Green Woodpecker seen from AG window feeding along edges of lawns for some time.

Sat 14th first Bluebell in flower Long Lawford

Sun 15th hedgerows well into leaf along the M5 (Worcestershire) and also along A40 in Monmouthshire (milder zones)

Plenty of Gorse bloom by mid month.
Fabulous Daff bloom this year.

Mon 23rd plenty of Chiffchaff Longwood

Wed 25th first heard Chiffchaff from garden

Wed 25th quite as few Chiffchaff Llwyndrissi forestry; near gate and car 2 Chiffchaff calling and visible then a Willow Warbler. This is early for latter (not sure heard in March before?) also could have been a case of a WW that has taken on the CC call (as was reported as happening due to their decline on Springwatch?) particularly as only one CC was then to be heard! Peacock butterfly sun basking allowing close-up photos by SRH

GSW drumming daily and often this fine sunny week, occasionally two of them

Plenty of Primrose and Celandine bloom month end

3 Pipistrelle bats above garden one evening near month end.
