I was intrigued by the discussion of whether in recent years more robins are being seen during winter in the Twin Cities(Charles Neil, Mary White and J. Baumann). I think that I have seen more robins, particularly in large flocks, in recent years. To put this hypothesis to the test I looked at the

I believe that in recent years the warmer winters have resulted in more availability of liquid water, which should have increased the area where robins can thrive

bject: Re: [mou-net] Northern Raven/Number Winter Robins There could well be multiple factors.  I will just add that the "distinct inflection point around 1996" noted by Val Landwehr happened at about the time that large numbers of hackberry trees, planted after the demise of the
