Man... It's been a long winter. Since the weather has let up a bit here(Delaware) I'm going to Bombay Hook to take pictures of the birds. What sort of things do I need to think about when shooting wildlife. I don't know what birds to expect there but there should be a lot since we're in the middle of migration. I'll be using my Canon 100mm and maybe my new Sigma 20mm. I've never been to this park however I think it may be a drive through because it's pretty big. If you have any ideas or experiences you want to share I'd appreciate it.
