Thanks everyone for all of the great suggestions.
Chris, thanks for the heads up on the school field trips. That can make shooting tough for sure.
Jon, thanks for the offer. I'm still working out my itinerary for April. I have a couples of places that are for certain but I try to work the east, southeast, southwest and then west central. The order is yet to be determined. Once I have a clearer idea I'll contact you if Corkscrew or Ding Darling are on the final list.
CDiver2, thanks for the link.
Liz, I've been to Viera multiple times and will try to work it in again, most days it's productive. I've been to Cruickshank a couple of times and got some good shots of a Pileated too. I'll look into Venice but it appears that a lot of the nests are a pretty good distance. Also. I'm trying to get more raptors into the mix this time, maybe some Swallow-tailed Kites, owls, hawks, etc. I've photographed the Burrowing Owls a few times on both coasts but might try again this year if possible.
Ian, thanks again for all of your tips and info. I'm working toward mid April so that should get me in just before they close Ding Darling, unless they move the dates. I'll probably call ahead to be sure. You got great results at Corkscrew and around the state. I'd be more comfortable with two weeks down there but I'll have to condense my opportunities into a week and hope for nice weather.
Thanks again everyone.
