Here are the details of the data being sought as I promised following the talk. Numbers of roosting birds for most species are likely to drop significantly around early summer in the peak of breeding season, so please be diligent in reporting observations while these roosts are still easily detectable.
Please note the additional category of certain absence data being sought for those who were not present at the meeting. Roost flight and roost site observations are being collected for any and all colonially roosting species.
Roost Flight Observations
Roost Site Observations
I am now collecting absence data for the species we are likely to target in the first year of the roost survey, to ensure gaps in my data reflect roost absence rather than lack of birder engagement.
Observations that fit any of these categories with be gratefully received and can be provided by reply email or to
