Hawksbill success!

We have been continuing our efforts to capture and tag hawksbill turtles from the Georgetown pier during the evenings. Finally, we were rewarded for our efforts when the team managed to recapture the large hawksbill that had been too heavy to lift onto the pier on the previous attempt.


This time, we were better prepared for such a large animal, the biggest hawksbill recorded in Ascension to date, and with the assistance of ropes and a higher tide managed to lift the turtle onto the pier. Sam and Nicola Weber, from Ascension Island Conservation, were able to take measurements and a  biopsy for DNA analysis.

Sadly, this particular turtle has had a previous encounter with humans and we found a large fish hook embedded in its face. Because the hook exited very close to the orbit of the eye the decision was made to leave the hook in place to rust out, rather than risk further injury to the animal's eye by forcefully extracting the hook.

Unfortunately the same turtle has been seen on a subsequent night and we noticed that now a plastic bag has become entangled with the hook and may be causing some distress and discomfort to the turtle. If we manage to capture the animal again we'll attempt a removal of the hook. If not, hopefully both the plastic bag and hook will come away in time.
