Decent suggestions there folk. Thanks. Not sure how we’d make a Larsen trap out here though. You need five different signatures and a full risk assessment just to take a photo; cobbling together unofficial equipment using pallet scraps is likely to be frowned upon. Interesting about the step up/step down thing. I guess we can try to lure them up to the helideck.
Happily, although not quite for all involved, it appears there were a few pigeons oh the boat too. We saw one of the kestrels take one out just before end of shift, so at least they’ll not go hungry.
As for why they’re here, it happens pretty regularly:- bird find a comfy perch that just so happens to be a ship in harbour and falls asleep. Ship sets sail and when the bird wakes up it’s 150 miles out at sea. It’s normally pigeons, starlings and sparrows though. Only recall one other bird of prey in the last 10 years.
