Dear Phyl
Two interesting articles on birds and tools:
Boland, C. 2003. Bird brains. Nature Australia 2003-2004. pgs 47-53.
Hunt, G.R and Gray, R.D. 2003. Diversification and cumulative evolution in
New Caledonian crow tool manufacture. Proc. R. Soc. Lond. 270: 867-874.
There are many such publications but these give a basic introduction.

It sure does. And I think we had this conversation about 2 years ago on COG
list. Tool use was thought to be a unique characteristic of Humans, until it
was found in chimps, then in gorillas and orang utans, then in Ravens, and
Darwins finches, etc
The more you look the more you find. It is still amazing in its own right.

Thanks Carol. So if SBBs use moss and sticks as paint brushes, does that
make them tool-users? David Attenborough makes much of what he calls
'tool-makers' in his Life of Birds (TV and book), mentioning two species
only, one of which is the Galapagos woodpecker finch: he says its use of a
cactus spine to prise out grubs has 'brought the bird world-wide fame'.
