The main focus of the next few days and the primary aim of this expedition was the geotagging of Sooty Terns in a joint venture with Ascension Conservation. However, Mark C is writing a paper on this subject for the 2016 Sea Swallow so not wanting to steal his thunder that is where I’ll leave it. See link below for Sea Swallow archive.
One of the secondary aims of the expedition was the continuing study of Brown Noddies which I’m glad to say are on the increase at both Mars Bay and Waterside. The study involved the catching, ringing and re-trapping of birds across both fairs. Measurements, weights and blood samples were then taken and these biometrics (hope that’s the right term) will be used to add to a growing database on the species.
First of all we used GPS devices to map out where the Brown Noddies were nesting. This mapping information was passed to Ascension Conservation for future use as well as being used to find the birds in due course for our study. Below are a few images of the birds when found. I’ll show the study work in the next entry or two.
