How many people contribute records to county and local bird reports in Wales?

How much data do those county recorders manage and through which channels?

How wide is the coverage? More detail in Alt Text.

Number-wrangling while I'm writing the @birdsinwales.bsky.social 2024 report.

#BirdingWales
Slide shows the number of bird records (not including those from structured surveys) contributed by birdwatchers in Wales to the national record through a variety of channels in 2024. Of 637,636 records, 67% were collected through BirdTrack, 27% through eBird, 4% directly to county bird recorders, 2% through the four Local Environmental Records Centres and the LERC Wales mobile app, and <1% through iRecord (figures are rounded). It is estimated that around 4000 people contributed records, making counts equivalent to 5.6 million birds. A map - produced by the British Trust for Ornithology - shows all the locations in Wales from which BirdTrack and eBird records were submitted. There was almost complete coverage around the coast and in the main river valleys but far fewer in the uplands of mid, west and north Wales. In total, records came from 277 of the 282 (96%) 10-km squares. The two main recording apps provided 26,089 complete lists which is the most useful way of providing records, during 49,573 hours of recording effort. Massive thanks to everyone who contributes, even bigger thanks to county recorders who manage all this data. My thanks to Simon Gillings at BTO, Sarah Woodcock at BIS on behalf of LERC Wales and all the county recorders who provided estimates.
