That was the question on everyone's mind as they lined up on Richmond riverside, waiting to be assigned a specific bat to count. Soprano, common, nathusius pipistrelle, plus daubentons, noctule and a few other species. We set out bat detectors to their corresponding frequency and lined up on both sides of the river for the final count of the year.

After a slow start the Twickenham side crew found a hotspot at the far side of Marble Hill Park. The walk ended near the White Swan pub after we made about 20 stops every couple of hundred metres. We then marched all the way back to Richmond and convened at the White Cross where Ken very generously got two rounds in.
