One day the kids were outside and told us they found a birds nest. When we went outside we could only see this tiny thing the size of a silver dollar that did not look like much of a nest. Sure enough there were two tiny, tiny humming bird babies inside. It was so amazing that anything is that small. We were able to watch them grow, see the mommy humming bird come to feed them, and then eventually fly away. What an education for all of us. Love it!
