Re: [mou-net] Northern Raven/Number Winter Robins

While the availability of fruit is important, a more limiting factor in numbers of robins in winter is the availability of liquid water. 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

Re: [mou-net] Winter Robins

I know when I ran the CBC for the Audubon Chapter of Minneapolis we found a huge flock feeding on Buckthorn berries in Island's of Peace Park in Fridley, MN in 2001. It was a flock of over 1000 birds. I think their winter numbers are tied to food, and temperature. On Thu, Dec 6, 2018 at 6:18 PM

[mou-net] Winter Robins

I think hackberries play a role. I don't know when the cities began planting hackberry trees on boulevards, but I think it was not many decades ago. Most of the trees do not look very old. Did large crops of hackberries begin to appear within the last 10 or 15 years? On the 2008 St. Paul

Re: [mou-net] Northern Raven/Number Winter Robins

I just heard this evening that Robins eat Buckthorn berries. Of course, we are trying to eradicate that invasive. I hope that isn’t causing less food for the robins. Becky Field Sent from my iPhone > On Dec 6, 2018, at 5:36 PM, Jason Frank wrote: > > It would be interesting to compare the

Re: [mou-net] Northern Raven/Number Winter Robins

It would be interesting to compare the data of outstate CBCs as well. I haven't lived in Minneapolis during winter since 1997, and it seemed noteworthy to me to see large numbers of robins in the winter. A few years ago I visited Minnehaha Falls around Christmas and couldn't believe how many there

Re: [mou-net] Northern Raven/Number Winter Robins

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
