Shade Bluebells lasting well into June (unusual).
Oak & Ash belatedly attaining full leaf early month
Mon 7th Llanybydder Swifts at Wilsons warehouse (former mill)/ old train station (10-12 combined) and Rhydybont chapel (5 or 6) but none seen at Aberdduar chapel (only there 10 minutes).
Mon 7th forestry above Llanybydder, parked at main entrance for a change as late, Cuckoo calling not far away (almost sunset); first Nightjars (2 or 3 heard one seen), some decent churring at one point; still plenty of WW and CC in song.
Sat 12th 4 mile walk along lanes and tracks about Mynydd Pencarreg: 1 possibly 2 Cuckoo heard, Stonechats, Wheatear?, lots of Skylark and Meadow Pipit, CC & WW; still fresh well- shaded Bluebells in number; Laburnums beautiful caught them just right!
Sun 13th good showing of the village Swifts this evening much chasing and screaming by 15+ birds..
Fri 18th forestry cuckoo seen and calling quite a lot from close (within 100m), this is quite late now to hear one; plenty of bird song still; plenty of Foxglove out.
