Thanks Laurie,
This is an alarming study, perhaps. However, the size of the overall population
and the number of breeding pairs during a single survey are not the same thing
at all. At the reported rate of decline the colony will be extinct in 4
years. Declines of that magnitude are extremely rare. Declines like that are
not caused by competition. Perhaps the birds are not breeding in large numbers
this year due to food/sea temperatures/recovery of previous season/etc. It
doesn't seem like good science to sound the alarm when there are many
alternative explanations and little information. The BBC should know better.
