We have the cutest little titmouse who is building a nest in one of our trees. Every night that we sit on the porch he lands on our heads and pulls out a few hairs for his/her building project. I've never seen such a brave wild bird. Last night he/she even tried to land on one of the dogs for a different variety of hair! He/She makes us laugh so hard. So here's our question... In the bird world, who builds the nest? Mom or Pop? We would like to know so that we can name this little bird.
