Are Black Butcherbirds fussy eaters?

[Jan England <>]

This is a query on behalf of Dawn Magarry of Cairns.

"What's wrong with a nice soft gecko?

We've seen our resident Black Butcherbirds bash the hard wings and legs off
beetles, grasshoppers and cockroaches, consume frogs, skinks and the odd
baby birds with no trouble.  But when it comes to geckos, on two occqasions
we have seen them catch and kill a gecko (the house variety) and only eat
the tail.  

Can anyone explain why?"

I will pass on all replies to Dawn.

Thanks          Jan
