There is remarkable dissonance between the view put forward on the above
web site that Camphor Laurel is a severe threat to birds and suggestions
that availability of Camphor Laurel as a food source may explain recent
increases in range & abundance of a number of frugivorous birds.

There were unsuccessful state&federal nominations of Camphor Laurel as
a threatening process (presumably by the author of the above web site)
and the reasons for rejecting the nomination give a rather different
assessment of the evidence to camphorlaurel.com:

http://www.environment.nsw.gov.au/determinations/CamphorLaurelKtp.htm

The archive contains various reports of birds feeding in Camphor
Laurels e.g.:
