We have a mockingbird who hangs around my bedroom window Every. Single. Night. He starts chirping about 1 in the morning and keeps his/her happy song going, nonstop, until about 5:30 a.m. I am glad he is a jubilant critter and I certainly don't want to destroy his joy de vivre but I would like to lean out the window and politely suggest "Daytime little bird"
Mockingbird singing at night. This is not my video but is similar to what I hear each night
