Very interesting. I was in Edward Gardens Saturday afternoon trying out my new 'toy' (a Canon SX50) and there were at least 3 pairs of cardinals looking to be fed (peanuts - don't leave home without them!!) but they were very quiet. It's really a fun camera, now if Canon can only figure out a way to 'speed up' the lens, especially at the long end (dream on Howie) it would be close to perfect!
