["Anna Varney" <arvarney@xxxxxxx>]

Hi all,

I've got a nest box at my house in Perry County.  The first clutch of 5 eggs 
fell victim to predators-my fault that I didn't install a predator guard in 
time.   
The second attempt contained 4 eggs and all fledged (Noel guard).   
The third attempt contains 5 eggs.  I watched today and found the same adult 
male from the previous two attempts (he's got a white patch on this right 
scapulars).
So, my questions is could he have taken a new mate (due to death or injury) or 
could the mate that he has had break the normal pattern of decreasing clutch 
sizes?
