It may be that despite the fact that many SPs are killed along the
roads, the fact that grain spills are found along roads all through
their habitat may enable survival of a greater number of young each
year. It's difficult to think how you might test this hypothesis.
However SPs seem more common in the 2000s than they were in 1990s in
the area north west of Canberra, at any rate.

It is possible the increased number of road kills is because there are
simply more birds on the road feeding on grain.

The drought also effected the breeding and survival of all wildlife. This
spring I have observed more babies than I have for a long time. I suspect
that there are more parrots this year for this reason.

I agree with John here, I think the numbers of Superb Parrots are
Increasing. At least I would like to think so. Given my observations near
Wagga Wagga late last year (and confirmed by others), and my sightings near
Molong, Cowra and Nyngan over the last 2 years I really think they are on
The increase.
It is possible the increased number of road kills is because there are
Simply more birds on the road feeding on grain.
