Nature notes

Fri 2nd Aberduar chapel, Llanybydder: inspected the chapel this evening, extensive droppings staining to chapel walls just beneath the 1 - 3 inch gap kindly made by the workers last Autumn to accommodate the Swifts. 6 or so main foci of the staining suggesting nest locations, these were only obvious through close inspection, as only one large stain was visible from the Surgery car park about 50 metres away across the road. A couple of Swift seen high above and heard to scream.

Onto the forestry, another Flying Ant evening, taking advantage of the warm, close and still conditions. 2125 as getting dark, we were inspected over and over again by a pair of 'chucking' apparently agitated Nightjar, flying round and round over our heads, sometimes perching in nearby trees and with some churring. Came withing a few metres again, gave brief impressive wing clap too, observed for half hour or so until almost completely dark as walked the half mile back to the car.
Driving back loads of moths, creating a constant 'snow flurry' in the headlights.

Mon 5th Nightjars gave a bit of a performance in spite of breezy weather

Tue 6th 20-25 screaming Swift quite high above Teifi as viewed from Lampeter campus after 2000 hrs, then dusk 2100, about 10 above OB, University, with one bird entering hole at chapel side of inner quadrangle

Fri 9th no Swifts or Nightjars on a damp and windy evening..

Tue 13th pleasantly surprised to find Nightjars presence still in the forestry above Llanybydder, almost gave up as starting to slowly walk back to car (with pauses) when at 2120 in near dark a short churr began, followed by another few minutes after. Then heading back to car once more (just 200m from car) one circled us twice within 10-15 metres! Weather cloudy, light breeze, 13c.

Wed 14th pleasantly surprised once more this afternoon to sit a the bench in the inner quadrangle of Lampeter Uni to see a Swift exit a nest hole, then a pair feeding over the building, likely feeding a late clutch of chicks..

Sat 24th Chiffchaff heard singing at AG (very briefly) and then at Long Lawford (close proximity and proper song and also saw this bird). It was a hot sunny afternoon (max 28c). Don't recall ever hearing one in August, so now I have heard them sing in each month from March to October (they often can be heard resuming their singing in September, even early October as they migrate south)..

Mon 26th mild, still evening at forestry above Llanybydder, unsurprisingly no Nightjars as most likely they have now departed on their journey south

Robins commenced their Autumn virtuosos month end, likewise have a few Wrens, all of which  thankfully breaks the August silence but not forgetting the contribution by twittering Swallows which seem to have been numerous this year!
