John Bull in his "Birds of New York State" has a section on migration of Redwing Blackbirds. I used this as a reference in a biology course I audited after retirement. Here is an excerpt from what I wrote: During the spring migration, 100,000 were recorded at Montezuma on March 22, 1958. In the early 1900's Arthur Allen kept a three year record of Red-wings migrating through Ithaca. From their plumage he was able to distinguish males from females and adult birds from those hatched the previous year. The record he reports is for 1911 and as he remarks the actual dates will vary from year to year, but the order in which the males and females, migrants and residents will remain. (I wonder if there has been any significant shift in the 80 years since Dr. Allen made his study.) Here is what he found: males arrive on the scene, followed two weeks later by the resident females. The migrants that appear are presumably on their way to Canada while the immature birds that will take up residence may have been searching for green pastures.

Blackbird squabbles bothered me, with one pair attacking another pair's baby, etc. Plus they would try to roost on my house. And peck at all my growing things. So, since I have soil with plenty of small rocks I started waving my arms and then throwing rocks NEAR them, not at them. After a few days they learned that arm-waving precedes the rocks, and they would fly away. Next I would slam a door or sliding window before going outside to waive my arms. Persistence paid off and from then on the blackbirds were deterred from spending much time at my place just by slamming a window or door. The next year they only needed a few days of re-training. My neighbors down the street often have fifty blackbirds on their property. I seldom have any.

There were over 100 dead birds that dropped over in Geyserville, CA off the 1010 Freeway this past Saturday. There were also a rather large number of Rooks and Choughs over in Sweden that died.....not to mention the birds in Arkansas, Kentucky, Italy and the fish, crabs, etc. in various places around the world. All in clusters, all falling on or near or within two weeks of, the New Year. Scientists are saying that mass die-offs are very common in birds, especially in winter....as for the fish and sea-creatures, they're saying red tides are on the increase in those areas. So this is hard to pin point....and don't get me started on the conspiracy theorists....egads. Thank GOD He is Sovereign over *all* of it. (Colossians 1: 19-20)

For three days last week a large flock of Red Wings turned over the leaves in my back yard. There were so many of them that it looked as if the ground were moving with all the leaves being tossed. They never touched my feeders or the suet. This was the first time I've ever noticed them up here on the ridge. Normally they are down by the creek about a half mile away. Two more firsts this winter. In late January there was a Towhee on my BOSS feeder. Saw it only once. If it came back I missed it. Last year I saw one under the Suet feeder picking up pieces but this is the first I've ever seen on the feeder. 20 years ago they were all over the place but now that there are no empty lots left I very seldom see any. There just aren't enough woods left for them. Another first I could do without, Grackles. Never had them before and they will empty out a feeder amazingly fast. Wish they would move on.
