Following Nikolas's email I just did a search of Barau's Petrel papers and 
found one good paper - Pinet et al. 2009 - BARAU’S PETREL PTERODROMA BARAUI: 
It is a broad paper focusing mainly on the conservation of Barau's Petrel. Some 
disturbing facts:
A recent survey of cat scat around 2 (of an estimated 10 colonies) found 57% 
contained Barau's Petrel remains. Research on these 2 colonies found that at 
least 900 Barau's Petrels A YEAR were killed by cats. 58% adults 42% young.
Urbanisation of Reunion is also a major issue. Between 1995 - 2008 more than 
5000 fledglings were rescued - being grounded around lights. 90% survived! i.e. 
10% didn't
Population estimates in 2000 were of around 3800 breeding pairs. Discovery of 
new colonies has increased the estimate since to to 4000-6500 breeding pairs. 
Total population could be somewhere between 15000-20000 birds. The paper says 
there is not enough data to suggest a population decline but goes on to say 
that without intervention, modelling suggests they will be extinct within 100 
Anyone helping the French with island pest / predator management ??!
