Time For A Shutdown

For a couple of years now I have engaged in periodic purge cycles where I let the feeders run out over the course of two weeks or so.  This has the happy effort of discouraging marginal pests like Red Winged Blackbirds without really impacting the knowledgeable regulars, such as cardinals.  I think it is high time for me to perform such a break.  I may load the feeders once more to get past our latest bout of unpleasant weather and as we nudge into a nice springlike period, close the bins.  I will be interested to see if my remedy continues to perform as usual.  I'm tired of blackbirds!
