Yeah I know. I have one terrorizing my cat right now. That's how I'm getting decent shots of this one. The same bird was as friendly as it could be a month ago. It would follow me around singing and doing their mating ritual dance (although some think it's some dance to scare insects into flying so they can go after them but that doesn't make sense to me). It would sing all day and all night before. Now it only does that chirpy sound that it uses to warn things away from its nest. In another month it will be singing again after it's young are out of the nest. They can be strange critters.
