Yes there was a BOCA sparrow survey in Melbourne
years ago. Dare I say I think nothing happened to it (just like several others
like that). It would be nice to be proved wrong. Maybe they still have the
results in a box.
In 1978 I did my honours thesis at La Trobe Uni
on a comparison of the social behaviour of the House Sparrow & Tree Sparrow.
(On the basis that the former is sexually dimorphic and the latter is not, not
only that but unusually in such circumstances, both sexes of the Tree Sparrow
resemble the typical male of the genus, rather than the typical female of the
genus.) Not surprisingly, the Tree Sparrow has a stronger social bonding and
attraction than the House Sparrow.
Anyway as to where it is common, the Tree
Sparrow certainly was abundant about the campus that year and I believe still,
as I visit them every year or two. Although a large part of my work was based on
captive birds, caught on campus. Also the Melbourne Zoo is the best (not the
cheapest) place to find them "underfoot".

Wasn't there a BOCA
survey of sparrows some years ago, possibly
before my last flight to
Oz. What did it conclude ?
