Catching, tagging and measuring

It’s been a busy last few weeks collecting data from the Bass rock gannets.

As I’ve not had much time to sit down and write anything I thought that I’d just share some pictures with you.

When we fit a gannet with a GPS logger and altimeter, we not only fit it with two identification rings but we also take the opportunity to take some quick and basic biometric measurements from it. These measurements not only provide an indication of the condition of the individuals we are tracking but they will also allow us to look at relationships between size and behaviour.

The whole process from catching to releasing take no more than about 10 minutes and is documented in the photos below (taken on a number of different days!)
