Easing my concern for the nestlings

Although I can't see them, I think I can hear them but I know they're up there! The nestlings in my gutter have hatched! I see mama finch feeding something and dad finch feeds mom. Like I mentioned in a previous post, I'm a little concerned that if a nestling falls out of the nest pre-maturely, it is a long fall to a concrete patio. To ease my concerns, I keep my umbrella underneath just in case. I figure it will at least break the fall halfway down. Now if I can just keep it from raining too hard and drowning them :)

Here's dad after he stopped by to feed mom...
