Chuck: Even though your "Friends of Balcones" article shot my hypothesis down, it was very useful. Thanks!

Steve and TexBirders, While it may very well be that the Gov't Canyon Mocker is immitating a local sound, I'm sure you're aware that Mockers also move around and disperse, often bringing their natal "dialect" and sounds with them. I wrote about a particularly vivid example of this that occurred on Balcones Canyonlands NWR in May 2010: http://www.friendsofbalcones.org/chucks/335519 That was a bird which uttered an amazing array of deep South Texas/Northern Mexico bird sounds which it could not have learned any closer than 250 miles from that Refuge.
