On the Portuguese "Fórum Aves" there is currently some discussion on whether the Azores are actually part of Europe (geopraphic versus political regionality) and whether "Priolo" (the Azores Bullfinch) is the most threatened species. Other European breeders (White-rumped Swift, Trumpeter Finch) have smaller populations. It has even been argued that the Azores Bullfinch might not actually be a separate species.
i've always thaught that the zino's petrel was the most
but what do i know
oh its a subspecies
didnt see that i think i should acctually read posts first!
I would not have thought that a White-rumped Swift was a 'songbird' either. If 'songbird' means passerine, then the Azore's Bullfinch, with an estimated population of 380-400 individuals must be the rarest. Further, though White-rumped Swift is rare in a purely Western Palearctic sense, it is not when you take the world as a whole- it is widespread throughout (largely) sub-Saharan Africa.
Zino's Petrel is not a subspecies - see other threads on this forum, but it most certainly is rare. Though new breeding sites have recently been discovered, they do not amount to many pairs.
For more info on the 'Priolo', go to
Further to my last post, I would have thought that actually Raso lark is the rarest passerine in 'Europe' with only 128-138 birds, according to BirdLife.
Something I had never really thought about; the term "Songbird" is bit of a loose definition, but since swallows and martins are included I had assumed that swifts were too!
Cannot get any good info on Trumpeter Finch numbers, but some of the Portuguese guys think it is probably rarer than Priolo (just bye the bye, there is supposed to be a small colony of Trumpeter Finch somewhere along the Arade river between Portimão and Silves which I and others have spent a lot of time trying to track down without success - if they do exist they are probably escapes given the Portuguese passion for keeping any bird which makes a strange or beautiful noise in a cage).
I was really just reporting a certain "feeling in the air" that there are opinions here that Priolo might not be the most deserving case for protection.
work is the bane of the birding classes
