Just a comment to Philip's observations on Ravens
and Currawongs.
Cool and wet weather is often detrimental for
breeding events, this coupled with past drought years, no wonder that food may
be scarce for a number of species. Pied Currawongs appear to be rather sensitive
to cool and wet weather early in the breeding season as I have noticed in the
past (Magpies are much better in coping with such weather conditions while
nesting). I found this always rather surprising since the Pied Currawong was
primarily a bird of the High Country where it should have encountered
adverse weather conditions more often.
Philip's Raven brood is rather late, several urban
and non-urban pairs have fledged young for several weeks already.
