Dear all
When doing bird surveys in the Bathurst district and Sunny Corner State
Forest where there are large pine plantations, we observed native birds
using the edges of the pine plantations, maybe roosting in them at night
but leaving them early morning to forage in the nearby native
vegetations, particularly along the creek lines where logging was
disallowed. Somebody published a study on this subject making the point
that edges were used by small woodland birds but not much further in
than maybe 50 meters - but I may have got that distance wrong. Was a
long time ago that I read that paper.
Once we witnessed somethng like 500 Yellow-tailed Black-Cockatoos flying
into roost in a pine plantation, groups of 20 - 50 (rough estimate)
flying in with much noise to find a space not already occupied. Great
sight!
