Lots of activity going at the Venice Rookery ., I was there the weekend before Valentines . I was able to capture some decent images with my 70-200 along with the extender . I don't think you'll be disappointed .
As for Corkscrew I was disappointed ., not much was going on the day I went though I think the cold front we recently had may have been a factor .
Thanks very much for the report. Venice is on my growing list, eventually I'm going to have to narrow it down. If only I had two weeks, but then I'd probably want three.
Have you been to Celery Fields Park near Sarasota or Myakka State Park?
