Hey Nancy!   
      
    NB> Any chance that might have been your local flock, having moved a   
    NB> ways....?   
      
   Possibly.  I have no idea how far they wander but given the frequency I used   
   to see them before mid May I thought a few city blocks might be the extent of   
   their range.  I am basing this on earlier evidence of spotting a different   
   flock in the school yard, which is roughly two city blocks away, after   
   spotting the local flock in my back yard a few minutes earlier when driving to   
   town a couple years ago.   
      
    NB> Does human activity arounf your area decrease after Labour Day...?   
      
   Yes.  Even moreso after Canadian Thanksgiving (second Monday in October).    
   After that it is just what we in the neighbourhood call regulars.  I have been   
   a regular for about 17-ish years now.   
      
   Life is good,   
   Maurice
