I reported / questioned hybridisation of Long-billed and Little at the Alice
Springs Ponds a couple of years ago (Long-billed escapees in mixed flocks with
Little). Glad to see I wasn't going mad!

Have looked at Google Maps and UBD and found Bradleys Reserve off the complex
of streets accessed from the southern part of Fox Valley Rd not Kissing Point
Rd. Is this the location or is it a differently named park/reserve off
Kissing Point? We're keen to see the Gang-gangs

Corella ???

Happy New Year to everyone. Two days ago, we noticed a group of corellas on a
bird-feeder at a friends' house in Samford, Q. At least 3 were definite
Long-bills while most were LC's. However, about 5 seemed to be a mixture of the
two - with beak length intermediate, more pink between eye & bill and throat
pink patchy & sparse - the jizz just didn't seem to fit. Could this be possible
& if so, is it common???

I think the task of automatic identification of birds is far harder than the
examples of number plate recognition and eye scanning.
In those cases the subjects are all arranged facing the same way, and are of
similar size. They'd have a poor success rate if the subjects were all
different sizes, shapes and colours, facing any old direction, hiding in the
undergrowth, etc. Compare the problem to what happens to a camera's face
recognition focusing when the subjects turn sideways.
Rather than identifying species I'd be pretty happy for now if my camera could
at least work out which part of the scene was a bird, and focus on it.
I assume the subject is tongue in cheek, but it's interesting that the incident
that inspired it was one where his "fuddy duddy" id skills gave him the wrong
answer (identifying a raptor from of photo).
He complained that in the field the bird would be moving, giving him more
clues. Perhaps that's the real lesson from his article. If one feels one needs
to see the bird's flight style to identify it, why try from a photo?
