G'day John
I've seen Pale Headed - Eastern Rosellas at a few spots along the line
of control (which seems to follow the Scenic Rim in SEQ), so they
aren't extremely rare. I've also seen mixed flocks, which is of
course, the precursor to the hybrids.
Regards, Laurie.

Interesting report on the intergrade Rosellas, Richard.
We lived for a number of years in both Boggabilla and Tenterfield,
NSW, where both Pale-headed and Eastern Rosellas occur. We never
found any 'intergrade' birds, though it's interesting to read of
these reports.
Cheers,
John Tongue

Hi. From 10.20 am until 12.30 pm yesterday (10 Feb) there were at
least 200
Fork-tailed Swifts hawking over the ridge where the Great Western
Highway
runs through Blaxland. I went back to the same spot at the corner
of the
highway and Bridge Rd twice, hoping to see other species of swift
in the
large loose flock, but no luck - no Little Swift or even any White-
throated
Needletails. At my house only 500 metres to the north I saw
absolutely no
swifts, they appeared to be concentrated along a stretch of highway
where
the uplift of wind from Fitzgerald Creek was bringing up insects.
There were
also quite a lot of welcome Swallows at lower elevations as well.
Conditions
were almost calm, sunny and humid, lots of rain the night before.
I saw only 2 White-throated Needletails on a recent work field trip
(seed
collecting), on Monday Feb 4th at Brunswick Heads, 2 single birds
about 5
minutes apart. Usually when I stay there during the summer there
are good
numbers of Needletails, last week was very cool, after the passing
of the
rain from cyclone Oswald.
The other interesting observation I made on that trip was around
Delungra
and Gravesend, west of Inverell, where I saw at least 4 pairs of
rosellas
that appeared to be intergrades between Eastern and Pale-headed
Rosellas.
They mostly appeared to be very bright sulphur yellow on the back,
with a
fairly bright orange yellow head, with varying amounts of bright
red on the
crown. I have seen one pair of what I assumed to be this intergrade
many
years ago near Cunningham's Gap in Qld, that pair both had very
bright
golden orange heads, with no scarlet.
Cheers, Richard.
