Sorry if anyone receives this twice - it didn't get through first time.
Wow Paul, that medical jargon is a bit above me. I understand you're leaning
towards exhaustion / dehydration etc. which would support the views of some
that these birds were caught off-guard by the recent bad weather.
Just a thought though, instead of blaming the weather as the primary cause,
perhaps these birds would already have been in a less than optimum physical
condition before they hit the gales? I'm not quite sure what they feed on
but overfishing, blowing up coral reefs, destruction of marine life breeding
grounds, and related unsustainable activities in Asia/Oceania and also here
in Oz, could be the reason these birds are not in top shape?
It's like the locust plagues that are supposed to hit us here in SA, they
are being written off as a natural disaster but apparently the primary cause
is grazing in the arid regions of Australia, where (so I'm told) decades of
cattle hoofs damaging the soil crust has led to the disappearance of a
fungus that used to keep locust numbers (eggs) under control.
As for the shearwaters, we should be carefully examining all leads to this
disastrous event and I'm glad your vet's examinations have contributed to
this.
