About a week ago as I sat t here at my window I saw two pigeons building a nest on the sill. Thursday afternoon I noticed while momma left the nest briefly that she had laid two eggs. Does anyone have any idea what the incubation period is? I remember from my High School Biology class that ambient temperatures and the humidity content of the air play a part in the hatching time, but can't recall exactly how long the incubation period is. Our temperature is running around 84 for the daytime high and humidity is about 65%. Any thoughts??

Just to keep the musical angle in here, I would like to play the Tennessee Birdwalk for the mother to be!
