Thanks to everyone for your encouragement! I do have binocs, and have been using National Geographic's Field Guide to the Birds of North America (3rd Ed), as well as Roger Tory Peterson's Multimedia Guide to the Birds of North America--though I will definitely get a copy of the book by Eckert that many of you suggested.
As far as birding being addictive--I think I'm already hooked! I went back to Loring Park today and saw the Great Egret again, as well as two double-crested cormorants! I can't wait for my trip. --Tiffany
