‘A SADNESS OF SHEARWATERS’ ON ABACO
If you are walking your favourite beach on Abaco right now, it’s quite possible you may see – or may already have seen – a very poorly seabird. Or one that is dead, I’m afraid. Or you may have read about this online. These poor birds may be (a) Audubon’s Shearwaters (also known as Dusky Petrels), which are the only permanent resident shearwater species on Abaco; (b) Cory’s, Great or Sooty, which are transients; (c) Manx, which is a rare ‘off-course’ vagrant.
At the moment there are plenty of posts and threads on social media about the current die-off. People are naturally upset and concerned, and want to know the cause of the phenomenon. I am recasting a post from last year to explain why this happens.
Exhausted shearwater beached on Abaco
Each sad bird is part of a tragic and recurrent phenomenon, a so-called die-off event. It almost always happens in June. The pattern is much the same each time, though the mix of shearwater species that succumb may vary. I first became aware of this problem in June 2015 and wrote about it then. That bleak time lasted for about a week, and many reports came in from mainland Abaco and the cays, stretching from Green Turtle Cay right down to Crossing Rocks.
There was thankfully no such problem in 2016, but in 2017 – also in June – there was another die-back event involving a large number of Audubon’s shearwaters (Puffinus lherminieri) appearing in the tideline and on beaches. Many were already dead. Some were still alive, but in a very poor state. Their prospects for survival would have been very low. A few birds were captured and cared for, but even then the chances of recovery were not good.
Two years on, in 2019, the melancholy cycle repeated itself. Melissa Maura, well-known as an expert in the care and recovery of creatures of all kinds, posted an alert and some sound advice:
A heads-up to all Island folk that it appears to be a summer when exhausted Shearwaters (pelagic seabirds) are washing up on our beaches in Eleuthera and Abaco. I have had two calls in 24 hours. Should you find one, understand that it will be in a severe state of exhaustion and stress and that excessive handling will kill it. Please put in a safe pen on a sandy surface, with shallow pan of fresh water and try locate either fresh fish (important) or squid from a bait shop. This may have to be administered by gently opening the beak and inserting one inch long piece of fish every couple of hours until stable. Ideally they need tube feeding, but very few folk can do this. Please contact me on private message if you find any…

Let’s hope the live ones have the strength to take off… & find fish
IF YUO DO FEED ANY BIRDS SMALL FISH, BE SURE TO TURN THE FISH SO THE BIRD SWALLOWS THE FISH HEAD FIRST OTHERWISE FISH SCALES CATCH INSIDE THE BIRDS THROAT. PUTTING THE HEAD IN FIRST MAKES THE FISH GO DOWN SMOOTHER

Excellent point! The rescue birds I’ve seen seem to be turning the fish by instinct luckily.
