CAMPHOR LAUREL TREE with CROWS NEST 7th March 2011

 Quick crow sketches

The Camphor Laurel tree, native to South East Asia, was introduced in Australia in 1822  The tree is now a declared menace.  It contains significant amounts of various chemicals known or suspected of being toxic and carcinogenic.   It easily ranks as the most toxic plant in Australian history.  Most birds suffer from eating the berries of the Camphor Laurel tree, either by sterilisation, or death.  Crows, like to feed on the top part of the tree, on the new berries.  They seem to survive the toxins, and they build their nests in the trees.  Only occasionally will a crow die, due to camphor addiction.  Sadly, some of our native species of birds have become extinct, because of these trees.
