Today I was lucky because I caught a glimpse of an egret.  I believe it was the Great White Egret but I'd like to call it a white heron.  This is because it's neck was extended and the little white fluffy parts of it's tail feathers were hidden from view. 
Yesterday I had to laugh because I heard a cat-bird.  Nothing is funnier than listening to a cat bird call.  Their song is pretty good too.    What this reminds me of is how at the Nature center a loooooong time ago a naturalist was demonstrating how he could catch birds in a "birding net" mid their migratory routes.  He had a fledgling and asked us how we knew it was a young bird. 
There were many ways to answer his question, and I said "by it's cry".  The naturalist said "No".  The Gray cat-bird he was holding could not be identified as a fledgling by the noise it made.  This is something to ponder and I'm sure a scientist out there somewhere is asking the same question.  Is there a significant difference between an adult and a juvenile cat-bird cry?
