In answer to a question from a Northerner after reading my new Christmas novelette: Yes, birds in Texas do nest in the fall and winter as well as spring and summer and they really like to line those nests with hair and other soft, insulating materials. For the most part, birds here in the fall and winter have migrated here from the north and our spring and summer birds have migrated south. However, our cardinals stay here year round and it is not unusual for them to have baby cardinals during warm autumns. They are some of my favorite birds at my place. I love to throw my hair out for the birds :)  This wonderful photo is by wonderful author Jeanell Bolton, taken at Christmas a few years ago.
