We do have a way to test these "feelings". In 1979-80 I organised a
garden bird survey through the Queensland Ornithological Society
(published in Sunbird 25:1-14 1995), which
received records from 100 gardens in Qld, mainly in the SE. In that the
Torresian Crow was ranked no. 7, recorded from 71% of gardens and in 37%
of all records. The channel-billed cuckoo was no. 100, recorded from
only 1.9% of records (using only summer records, Sept to Feb).
I intend to repeat this survey in 1999-2000, 20 years on and using identical
methods and then it should
be then possible to answer this question, and others, with hard data.
You'll just have to wait a couple of years.
