Hi Bill,
You must've missed Jim's 11/20 MDOSPREY posting  below:
 
 
Although i have normally retired my hummer feeder in OCT  or NOV, i decided 
to keep it maintained until early JAN this year due to the  persuasive 
argument posted to MD Osprey to that effect.  So far this effort  has been 
without positive results in my case, but i've become curious to know  how many 
others are doing likewise.  
 
If you want to e-mail me off list, stating your county and  your 
intentions, i.e. maintaining feeders until just after the new year as i  will do, i 
will compile a summary and post it to the list sometime after  Christmas.  
Although it won't be comprehensive as some (many) households  will not have 
access to MDOsprey, it might be interesting.

Just a reminder  that this year is turning out to be an especially good 
year for vagrant  hummingbirds in the East. Please keep your feeders clean and 
full! If you  don't still have one up, consider adding one. In addition to 
considering this  a great idea in general, I am sending this by request of 
one hummingbird host  whose visitor might have moved on. Your yard might be 
next. (But hopefully its  mine!)

If you re-fill a feeder or add a new one this weekend, please  reply 
off-list to let me know you did so. I'd like to pass these notes on to a  worried 
hummingbird host who hopes to ensure lots of options for their guest  while 
its on the road  south.
