low tech bird quiz - answers

["Greg" <>]

Hi Philip,

I did not attempt your bird quiz as I am presently writing my thesis on the 
Black-necked Stork and, although tempted, did not want to get too 
distracted.  I did note your comments regarding storks excreting onto their 
legs and I can confirm that Black-necked Storks on the NSW North Coast do in 
fact do this but it is not a common activity.  It is almost certainly done 
to cool down and Black-necked Storks also excrete over their nests, eggs and 
nestlings, apparently for the same reason.  The behaviour of excreting onto 
legs, called 'chalking', has been commonly recorded in non-breeding White 
Storks in Africa.
