the single exception of the Swift, supposed to be Collocalia

I think there is no need for me to occupy your attention longer 
by any attempt at summing up what I have been saying. It is in 
the power of any one, with these facts before him, to see the 
inevitable result. All that I would in conclusion ask you to bear 
in mind is that this lesson, conveyed from distant colonies, 
should not bo lost. The causes that have produced, are producing, 
and will produce extinction in the Mascarene Islands and in the 
Seychelles are precisely the same as those that have been, that are, 
and that will be in operation in the Unitetl Kingdom. Hero the 
operation is slower, there it is quicker. That is really the only 
difference.
