WBBS survey: Pont Llanio area

 Completed my round of second BBS and WBBS visits yesterday. A few musings.

Good to see Goosander with c10 young at Pont Llanio and also Mute Swans with young on the WBBS.  Both species' nests were washed away a couple of years ago in floods.

But Sandmartins absent again. I was curious to see exactly when the last records were - the data revealed that they were last seen seen June 2020 (13) and prior to that 2019 (6), 2018 (7), 2017 (7), 2014 (6).

I had two Willow Tits (calling) 29 Apr 2021 but none in 2022 or 2023 (and none prior to that by myself or previous recorders). 

But I did note that Sedge Warbler had been recorded in 2015, a Dipper in 2014 and a Common Sandpiper in 2016 (April) - none of which I've recorded since I took over in 2019!

But given that other more regular observers have found, eg, Willow Tit and Marsh Tit,  it does show how comparatively short twice yearly survey visits do not necessarily provide a complete picture. Although statistically sound obviously.
