Bee hotel

One of my Christmas presents was a rather fancy bee hotel. I've been waiting for the weather to warm up to put it out in the garden. We finally mounted it on the house wall where it will catch the morning sun about 10 days ago. Tonight when I was in the garden I noticed that two of the holes have already been occupied by solitary bees. I was very excited and am now hoping that all of them will be used by the end of the summer.
