My observations are similar to Greg's. There was no dawn chorus around our
place this morning. Most of the dust clouds have cleared from the skies
above Ryde in the last 30 minutes and the sun has begun to shine. It's still
extremely windy though. I heard my first Noisy Miner call for the day about
10 minutes ago, but there's still very little bird activity, probably
because of the strong winds.
Although birds and mammals have different respiratory systems, the upper
part of the respiratory system of both animal groups are similar. So dust
and other debris are usually trapped by mucous in the nasal passages, mouth
and lungs of birds. They also sneeze and have nasal discharges to clear the
nostrils. Rhinitis (inflammation of the linings of the nasal passages) can
occur in birds when these linings have been irritated by airborne dust,
especially if the dust carries pathogens such as fungi & bacteria.

Nathan & all
Around my house, in the Newcastle area, all the birds seem quiet. The
Turtle Doves seem to be just sitting about not knowing what to make of
the red sky, dust and strong wind. Maybe birds are always quiet or
subdued on windy days but bird activity around here just seems to be
very quiet today.

Hey Everyone, I was wondering how the recent dust storm has been
effecting
the local birds. I have seen some birds flying almost sideways, but I
was
wondering if the winds & the Dust has had any added effects to the
Birds,
Eg, the dust geting into the birds lungs effecting their health?
