Re: [SBB] NSWO: Northern Saw-whet Owl in CCFS

[Karen Hoyt <[[email protected]]>]

I was banding with Blair at least a few of those dates, I am 
remembering mostly November.  We would come in very early, I am 
thinking 2 or 3 am and open the nets specifically looking to catch 
Saw-whets during migration.  No tapes were ever used, just the 
passive nets.
