Great site! I've heard of the flocks for many, many years in Belmont Shores, Long Beach CA. I never was about to catch a glimpes of them until a month or so ago while at a stop sign with my daughter. Not amazons however, but a very large (15 or more) flock of cherry head conures. Amazing site to see. I understand SF area has huge flocks as well. Netflix has a show you can watch regarding them.
