Nature notes

Severe weather first few days brought many Starlings into garden they drilled into the lawn to find insects leavibg hundreds of little circles and holes, they focused on softer areas where growth longer or sheltered under shrubs.
Daffs, Snowdrops and Primroses seem badly affected being flattened and wilted with drooping flowers, escaped this where well sheltered.
Countryside has that brown stripped down look with much new growth curtailed or withered inc Celandines and ferns
3rd Female Peregrine alighted on the holly tree sussing out prey though they had already left, really good view. Bullfinch in garden, had a good view of one feeding on seeds in along front boundary in Dec and just 10 feet away and for 10 minutes or so.

Mid month still profuse areas of Snowdrop (mainly recovered from cold), profuse Daffs now (also recovered to upright), also plentiful Celandine and Primrose bloom.

Late month pleased to see a Greenfinch on niger feeder (rarely seen past few years)

Month end still quite a few Daffs not yet opened to flower yet, still some Snowdrop in bloom, most over

Unusually yet to hear first Chiffchaff although they have been reported across Ceredigion since mid month here:
