We also have some of these. They could also be the culprits. There are also some of these beautiful little birds flying around.
The little birds flying around my yard are a beautiful part of your creation. I do not want to hurt them, but I am afraid of what may happen if they lay eggs in the porch swing nests. I enjoy my swing, and I do not mind sharing it. Help me to be a good steward in this situation, Lord. It seems that the little birds who are nesting in the swing have great perseverance. May I learn from them what ever lesson it is You feel I need. Open the eyes of my heart to see Your message and give me ears to hear, Lord.
