And I was wondering how the hell did you sneak up so close.
All credit to Rogwar, I think he's being too modest, a 300mm FL is NOT considered a very long lens at all when it comes to birding. I often use 400 or 500mm when birding, If I can get close enough I switch to the 200mm 2.8 but that doesn't happen most of the time. Most photographers who are big into birding will use something like a 500 or 600 f4, I've even seen one guy down at the bay a couple times with the Nikor 800mm f8.
