> For nice guy Rob Sandelins's benefit, it's not you, it's him!! As Anna's males take no part in nesting, the behaviour your saw was not nest defence, but most likely display territory defence. There are lots of native shrubs at CUH for females to visit. During my longish term study of "wild Annas" in Discovery Park, I kept notes on the object of male anna display. From memory I recollect the pecking order went something like this: #1 object American Robin, #2 object various small passerines including Bewick's Wren ,#3 object humans i.e. me!! #4 object, hummingbirds of all species and genders. Most surprisingly, or not, when you really get to know Anna's breeding system,female Annas were at the bottom of the list!! There are good reasons why this is so, but you would have to twist my arm. Let's just say, Rob, that you were grist to the Calypte mill. David Hutchinson
