Two Bird Houses

I took these two bird houses at my parents house. These ones are occupied. Not like my other bird house I took a photo of last week. My mom said a blue jay occupies the first one on the left. The one in the background has birds coming and going too. My mom seen various birds using it but said their are robins using it now. They have several other bird houses too but these two look the best. Both my parents love to sit on their porch and watch the birds.
