TUNDRA SWANS HAVE ARRIVED ON THE MISSISSIPPI
Tundra Swans on the Mississippi just south of Brownsville, Mn. We enjoyed the sounds and sight about 2-3 thousand Tundra Swans on Saturday Nov. 14, 2015. The swans stop in this area to fuel up on aquatic root tubers and rest before heading east for the winter. The number of swans here will increase over the next few weeks and we have seen as many as 20,000 swans here at one time. The swans will leave when the backwaters of the Mississippi freeze over. Last year was so cold (Thanksgiving Day had a high of 6 degrees), that the swans left early. This year is much warmer and the swans could pile up to large numbers and possibly stay into early December.
Tundra Swans and Giant Canada Geese. The Swans tip up and feed on aquatic root tubers such as the root of the Arrowhead plant. The swans have already had a long journey from the Tundra of northern Canada to Brownsville and they need to fuel up on these high calorie roots before taking off for the east coast.

Grackle flock of about 50 birds. Love the chatter of the Grackles as they head south for the winter.
Thirty years ago we would commonly see a single flock of well over a thousand birds. Now we are lucky to see a few flocks of 100 birds. The Grackles, like most of our song birds, are in steep decline. These birds need grassland and woods edge habitat and much of that habitat is now corn fields or parking lots for more malls.
