Nature notes:

Fri 5th Great Tit "teacher" call quite determinedly.

First week, quite a bit of fresh hedgerow foliage inc Primrose, Celandine, Foxglove (lasted from Autumn?).
Daff spikes emerged usual spot end of Bro Grannell, Llanwnnen; Bluebell spikes in garden

Mid month few Snowdrop in flower; first Daffs as usual just before Carmarthen; tits active (notice this and tends to mean no more real cold and Spring on the way); quite a bit of resh groth inc ferns and budding; first sole Celandine flower

Late month plentiful Snowdrop bloom; Blackbird snatches and some proper Song Thrush song; plentiful Hazel catkins, some since beginning of month. MIstle Thrush heard occasionally much of the month.
