Jim Williams has been watching birds and writing about their antics since before "Gilligan's Island" went into reruns. Join him for his unique insights, his everyday adventures and an open conversation about the birds in your back yard and beyond.
Tens of thousands of finches were counted at Hawk Ridge in Duluth this fall, in addition to 59,000 raptors. Below is the seasonal summary as written by Karl Bardon, count director for the Hawk Ridge Bird Observatory (www.hawkridge.org). He posted this Wednesday on the email network of the Minnesota Ornithologists’ Union. Bardon predicts that you will see some of those finches -- Common Redpolls -- at your feeders in coming weeks.
The official counting season at Hawk Ridge Bird Observatory for the fall
2014 season ended on Nov. 30. Although the raptor migration was
fairly average with a total of over 59,000 raptors counted, the non-raptor
migration was the best ever, with a total of over 357,000 non-raptors
counted (this is over 38,000 birds above the previous high season, and over
70,000 birds above average).
Much of this high count is due to the amazing
count of 111,320 finches, including 15,276 Purple Finches, 38,440 Common
Redpolls, and 52,389 Pine Siskins. This is the highest season to date for
all three of these species, but where did they all go? Judging from mou-net
postings, no large numbers of these finches have been reported south of
Duluth. It would seem that a major invasion of these species is underway,
so it will be interesting to see when and how many of these birds show up
in the south.
Duluth is certainly one of the best places in the country to
see finch migration, but this year the numbers were simply overwhelming!
For those who did not witness the daily barrage of flock after flock after
flock of finches moving down the shore, it may be difficult to conceive
just how many birds these totals represent. Even more amazingly, radar work
by the U.S. Fish and Wildlife Service suggests this diurnal migration counted
at Hawk Ridge may just be the tip of the iceberg, with unknown additional thousands
of finches potentially moving over at night.
Interestingly, this is not the first time a major invasion of redpolls passed
through Duluth without being recorded in the south, since the same thing
happened in 2011 when over 37,000 Common Redpolls were counted at
Hawk Ridge (mostly in late October). Although Common Redpolls are
generally thought to be on a biannual cycle, current data from Hawk Ridge
shows high numbers of Common Redpolls every three years,
including 20,139 in 2008, 37,759 in 2011, and 38,440 in 2014
(most of which were in November). So will redpolls show up at your feeder
this winter? I sure think so!

Interested in a little holiday birdwatching? This is a very good time of year to find eagles south of the Twin Cities along the Mississippi River. The opportunity will continue through the winter where there is open water.
The areas from Red Wing south will be good all the way down to Brownsville. Wabasha has eagles in addition to the National Eagle Center, well worth a visit.
From Red Wing south you can find hundreds of Bald Eagles, sometimes dozens in one location. Look on the ice, and in shoreline trees. You will be on Highway 61, a busy road. Get off the road to view the birds. Don’t try to do your watching from a moving car.
The Tundra Swans that rest late each fall in the wide backwaters of the river at what is called Weaver Bottoms have mostly moved on, continuing migration to Chesapeake Bay. As of last Friday, the 21st, a few hundred remained far from shore at that location. A spotting scope would be necessary for good looks. A good site is called Pool Eight, meaning there is a dam and locks at that river location. Check a map for precise locations.
Best viewing for swans is past. On a good day earlier in November at the right location tens of thousands of Tundra Swans can be seen. Put it on your 2015 list of things to do.
In deep open water, the river channel, you presently can find thousands of diving ducks and mergansers. A scope will make viewing much more enjoyable.
Given this abrupt start to serious winter weather, a trip sooner than later will be best. Much of the river is frozen over, and more certainly will freeze.
Both sides of the river offer viewing opportunities, by the way (although the Minnesota side brings you closer to the water). Cross at Winona, and return north on the Wisconsin side.

The term “flyway” as it applies to migratory birds has been used often lately in conjunction with concern about glass windows in the stadium under construction in downtown Minneapolis. We have heard comment about the Mississippi flyway and the birds that follow that migratory path.
The impression one could take from some of these recent references is that migratory birds follow the river bed or river valley in absolute fashion, right down the middle. That certainly would put a lot of birds over downtown Minneapolis or very close to it.
Actually, the Mississippi flyway stretches from western Minnesota to eastern Michigan. The flyway concept was developed by waterfowl biologists to designate the route used by migratory waterfowl coming from many points north. The U.S. has four such flyways — Atlantic, Mississippi, Central, and Pacific. Used these days for migratory birds of all kinds, it is a broad term.
Certainly some migrants actually do, by chance, follow the river closely. They must then negotiate a route through the city and its buildings. Birds in general, however, do not move along the flyway as through a funnel.
Sunday last five Bald Eagles circled above me as I visited a nearby orchard. The eagles cut over-lapping circles, often coming close to each other, but seeming to pay no attention to each other. The birds were just moving through, perhaps headed for Lake Minnetonka shoreline where eagles are often seen in the fall, waiting for opportunity to snag a coot or duck. One place to check for eagles on the lakeshore is along County Road 15 as it heads west from Wayzata. The road will sweep to the left soon after leaving town. Two marinas are there, and that stretch of shoreline often holds eagles in the tall trees that line the shore.
Sandhill Cranes by the thousands are putting on a spectacular show right now at Crex Meadows Wildlife Area just north of Grantsburg, Wis. The birds roost in wet meadows on the refuge, flying out in the morning to feed in area crop fields, then returning in the 90 minutes before sunset. Yesterday, a couple of dozen viewers lined Main Dike Road to watch the birds sail over their heads as they dropped into the roost site. It's as close to a bird spectacle as you're going to get around here.
The Crex visitors' center is located at the corner of County Roads F and D. County F is the road you take out of downtown Grantsburg. At D, turn right; the center is on your immediate left. Maps of the refuge are available there. The birds can be seen from other vantage points, but Main Dike Road is best because the birds come to roost immediately north of it. (If there are no maps available, follow County D east from the visitors' center to East Refuge Road. Go left (north), until you reach Main Dike Road, which will T from the left. Follow Main Dike west.)
Yesterday offered a beautiful sunset against which to photograph the birds, fortunate happenstance.
Grantsburg is a 90-minute drive from downtown Minneapolis. Take I-35W north to Minnesota Highway 70, four miles north of the Rush City exit. Follow 70 east across the St. Croix River, and then into Grantsburg. Turn left at the light. Follow the crane silhouettes painted in yellow on the road. The birds are expected to remain in the area into early November.
