What is the situation in the northern hemisphere, with their very extensive
natural pine forests? Are they as sterile as our plantations of introduced
pines are, with low species diversity and numbers, or have the birds
co-evolved with the pines?

I have observed Yellow-tailed Black-Cockatoos feeding on fallen Macadamia
and Pecan Nuts on the ground in South Grafton but his is unusual.

We must not forget that no matter how much bird habitat introduced pines
provide, and this would appear to be very limited, they are no substitute
for the local natural vegetation.

      I notice that cones found under the local trees seem to have been
completely chewed to pieces, but the culprits are Sulphur-crested
Cockatoos which will feed on the ground. I have never seen YTBCs on the
