That would be pretty cool. No way to see the babies in the barn swallow nest, the gap between the top of the nest and the floor above is only about 1.5" if that. Sometimes one can see some beaks when Mom or Dad come to feed. It amazes me that these birds fledge without ever having room to stretch or build up wing muscle. But when they follow a parent on the specified day, they drop off the edge of the nest and fly like they had been doing it for a week.I just love that these little birds trust us enough to make their nests in our space. It's so cool to watch them raise their young. I especially like that I can see the babies in the nest from the kitchen sink.
