Late-summer and autumnal calling by owls

Hi All,

I just wanted to make the observation that juvenile owls are now on the 
move, away from their parent's home ranges, and are encountering pairs 
holding territories for the first time. A lot of late season calling is 
defensive in nature as adults deal with the onslaught of naive and 
hungry youngsters looking for a good, and unoccupied, hunting ground 
with decent roost sites. Given that owls start territorial calling in 
December (Great Horned Owls), January (Barred Owls) and February 
(screech-owls) I don't think it likely an early autumnal photoperiod 
should set them off. As it happens I was just outside at the table on 
our deck doing some writing and the local pair of Barred Owls sounded 
off for about five minutes around 5:30 PM.

Off topic but of interest nonetheless: There was also a male 
Red-breasted Nuthatch in our (evergreen-less) yard this afternoon. The 
clever little fellow stole somebody's cached seed from behind the wire 
wrapped around our TV aerial.

Good birding,

Walter Ellison
