Pekinensis swifts are a bit special, they are different from our Swifts, paler, more like Pallid Swifts and their call is softer, also resembling Pallid Swift to our ear. Beijing is not far from the eastern extreme of the species' range.
After Terry's return to Beijing, and a few weeks, and a few emails later, we had ourselves a project. By now Lyndon Kearsley, ringer and geolocator fitter extraordinaire, was signed up, as was the Beijing Birdwatching Society. BBWS has been running a project to ring the Summer Palace swifts since 2007, taking over from Beijing Capital Normal University who started this survival study in 1992.
We originally planned to take just 10 geolocators, then Susanne Åkesson, director of the Centre for Animal Movement Research (CAnMove) at Lund University gave us 20 more. The 10 turned out to be 11, so we arrived in Beijing with 31 geolocators to fit.
So, on 23rd May, we arrived in Beijing, planning up to 3 days to catch enough birds to fit 31 geolocators. The evening of 23rd was spent giving a workshop to members of Beijing Capital Normal University and the Beijing Birdwatching Society on how to fit geolocators. They all picked it up very quickly.

On 24th May, at 5:00am we arrived at the Summer Palace to find the pavilion enclosed in mistnets, Swifts were already being caught on their way out. Two and a half hours later, we had deployed all 31 geolocators. This is testament to the meticulous planning, organisation and competence of the Chinese team.

We would like to thank, first of all, Terry for making all the right contacts in Beijing and Wu Lan, from the BBWS, who has worked miracles to ensure the Chinese authorities were comfortable with the project.
