Nature notes
Thu 3rd snatch of Blackbird song heard Carmarthen this lunchtime.
Sun 13th snatch of Mistle Thrush song on this notably warm November day! Also a Red Admiral.
Mid month with the very mild first half to November and continued lack of frost, many flowers are still in bloom inc Roses, lots of Ox eye Daisies in Lampeter, etc. Plenty of Gorse out (one of the few plants able to bloom any month of the year!). A few Dandelions giving a late show.
Brambles still extending at a rate comparable with late Summer, grass still growing (cut the lawns Sun 13th and in shorts both the latest ever).
Fri 18th Aberystwyth decent Starling roost of 5000 plus, no large single murmuration though, it was quite windy and mainly smaller groups going straight under the pier. 10 or so Turnstone just under the sea wall near the pier again it was high tide as with last month.
Sun 20th Neuadd lane, Llanwnnen: much fresh foliage evident (nothing below -2c as yet), inc Wild Rose, Honeysuckle these where the hedgerows have had their recent trim; much Celandine leafage covering the south facing bank; some Red Campions out. Blackbird dusk 'cacophony'.
Late month: growth continues albeit slowed down now, Buddleia sprouted fresh shoots since the trim last month. Some Oak trees hanging on in leaf, most other trees now bare.
Fri 25th Aberaeron prolific blooming in the town gardens (the 'second Spring' as reported on BBC), inc Roses, Hydrangea, Fuchsia and various potted plants. Also shrubs where trimmed during the Autumn have regrown and some of these flowering again. Typically by late Autumn frost would have curtailed this.
Sat 26th Bluebell spikes appearing under the Apple tree (note they were well out in the exceptionally mild Dec 2015).
Sun 27th Neuadd lane, Llanwnnen dusk: much flowering still evident, with Pink Clover, Campion and Daisy all out; fresh Hawthorn and Oak sapling leaves in the hedgerows; with Sycamore and Oak having fresh sprouting too; hundreds of Starling heading to local roosts
