Nature notes:
Tue 3rd Longwood and adjacent lanes: 2 Chiffchaff heard, a week or two later than usual, Treecreeper, many Mistle Thrush singing towards dusk. Visited Longwood, the area adjacent to visitor centre out of bounds for felling as there was extensive damage from Storm Emma at the start of March. Walked along lanes and numerous conifers blown over recently and from the east. Storm Emma was on March 1st - 2nd and not 'February' as stated on the woodland noticeboard.
Thu 5th several Chiffchaff Lampeter, went down by Teifi but no WW or Sand Martin
Fri 6th first Llanwnnen Chiffchaff
Sun 8th 2 Pipistrelles above trees end of garden, did see one or two bats in March as well..
Mon 9th First Willow Warbler briefly heard Lampeter University behind Sports Hall
Tue 10th first Bluebells out garden
Wed 11th 4 larger bats along AW lane, Noctules?
Sat 14th Willow Tit (?) observed and singing top of conifer end of garden
Sun 15th first Swallow Lwn!
Mon 16th Blackcaps top of garden singing
Wed 18th warm spell started, plenty of Swallow Lampeter, WW Parc-y-Rhos, many Chiffchaff.
Stitchwort and Violets, much Celandine, many Daffs on turn now
April 20th first UK Swift sightings (one at Bristol another Cwrtnewydd). There have also been some House Martin sightings - none spotted here yet its still at least a week too early for many..
Gwarfynnon bats (a few) back during last week, also new owner says he is Bat friendly
