Hi Mick and all
In Gordon Beruldsen's new book, eggs are described as faint
pinkish-white to pale pink or pale buffy-pink, slightly lustrous and
sparingly spotted or blotched with reddish-brown. mostly towards and
over the larger end. Size approx 20mm x 15mm, 2 or 3, occasionally 4.
Usual shape tapered oval. The photograph of a nest shows 2 whitish eggs,
one wioth bright reddish spots circling the larger end, the other with
faint reddish spots.

Hello all,
I'm sorting through my photographs from the last 12 months and have
been baffled by some photos that I took of a gibberbird nest that had
2 eggs back on the 5th August at Davenport Downs in south-west Qld.
The strange thing is that the 2 eggs in the nest were quite different
in colour and pattern to such an extent that I at first assumed that
there was a cuckoo egg in the nest. After closer re-evaluation I now
think that there wasn't a cuckoo egg in the nest. One egg was
noticeably pinker in colour, with denser markings than the other.
Normally I'd look up venerated egg references like North or Campbell
with a problem like this but the Gibberbird wasn't described until
AFTER these volumes were published (early 1900's).
Now, this egg variation within a clutch may be normal for Gibberbirds,
I'm no expert on them. I'd love to hear from anyone who knows about
Gibberbird eggs or for that matter whether it is normal to have a lot
of variation within a clutch of eggs.
Cheers
Mick
