Recently Professor Susanne Åkesson was at the nature center to talk about her research into bird migration and navigation and about here research work with Common Swifts (Apus apus) here in Lapland.
The following day I was invited along to watch the research work being done.
Here we are setting up nets at the nest sites to catch Swifts (Swifts here in Lapland are a little special because they nest in holes in trees)
Here is Susanne removing a Swift from the net
This individual had been fitted with a data recorder the previous year, which was removed and the data downloaded to a computer and a new recorder fitted
The birds captured were weighed
and some birds fitted or re-fitted with data recorders
and then released
They were very soon back in their nest boxes again
