This quickly proved to be a mistake and I moved the net to the middle of the area it was occupying; A Myiarchus, the mocker, and several G. fatii were absolutely fascinated as I set up the net but soon disappeared. I could not chase the mocker within 25 feet of the net. Eventually all the commotion drew 2 others by, but they were just as scary. The mockers spent all the time 10-15' up in the trees and when they flushed they flew through the open hambers, just below the leaves and above my net. Thoroughly feet- solid, I shot one of the mockers and moved to another pair which were in a large grove of mangarillo trees and set up the net, placing the dead mocker near or in the net and then made mocker like signs. As before when I set up the mockers [3] were fascinated but disappeared when I got the net up. G. fatii + a Platyspiza came to my mocker imitations; the Nesomimus spent most of the hour there singing from a perch 30' up in the tree and only once was within 20 ft. of the net; never saw more than 1 of these. A Yellow Warbler tumbled into the net and the Platyspiza and Camarhynchus had a good time zipping back and
