Jack Snipe Research Group

International group connecting sites throughout Jack Snipe (Lymnocryptes minimus) migration route. Undertaking surveys & ringing using thermal imaging.

It was great to present our Jack Snipe Tagging Project at yesterday's @UC_Sparsholt Research Conference & for third year BSc students to present their own dissertation research. We'll have further updates in the near future, so please keep a look out for new posts.

Our Hampshire team has been searching for suitable dayroosts to monitor. It looks like one they found recently may be just the ticket: in a quick visit with a thermal imager, they found 12 Jack Snipe. We'll be joining them to start a systematic survey programme.

One interesting dimension to our Jack Snipe tagging project is that the data are revealing that birds regularly use a matrix of dayroost & night feeding sites all within c10km radius. We've already found 2 dayroosts we were previously unaware of, so we'll now be monitoring these.

Last winter, with Natural England funding, we fitted GPS tags to 10 Jack Snipe in the Midlands Heathland Heartland project area in Staffordshire & West Midlands. One bird has just been recaught: its migration took it to Germany, Poland & Latvia before returning to Staffordshire.

Thermal imaging cameras have been an essential piece of kit in our Jack Snipe surveys. However, we plan to monitor the birds' return to their usual roosting areas as the water subsides by conducting a systematic survey of the site with a thermal imaging drone. How are others monitoring their sites?

Our other dayroost site is larger, but again we've seen fewer birds, though we saw 26 on our last visit. The main roost area consists of grasses & sedges, but has flooded recently. Jack Snipe have moved 5-25m to clearer areas amongst Heather. Has anyone seen anything similar?
