Bonasa umbellus togata. Lake Umbagog, Me. Sept. & Oct. 1893. Bonasa togata Oct. 13 of the breast which I was 2/ obscured on the 6 to 4 again to-day is produced partly by the duville from the wing feathers and partly by the ventral muscular action of the pectoral muscles, thus my old theory as to the drumming of the Partridge is again confirmed in every detail. I had the curiosity, however, to ask each of my three men to watch this bird through the glass & give me their impression. All returned fully convinced that the bird struck only the air, few had never seen a Partridge drum before, Charlie & other had seen several such, so the prime thought that the wings strike the log while but was perfectly wrong in that they strike the breast. Of course neither had had anything to make a favorable opportunity before with conviction especially pleased J.D. Boy 11. Albion, Oxford Co Maine. Bonasa togata s. vir (Migrates s. in autumn) Oct. 23rd 1895. Dear Mr Brewster— Thank you very much for that little story of the Covey or coveys flight of the winter of 1892. It has been a surprise to me for years that any of our wood birds should migrate; our forests must have more than enough food for them, and they are native birds, I don’t see what their motive can be. Our grouse were nearly silent for a few days, say from 12th to 25th of October. Then came the covings, in one day I could see they were few and far between, in three days it had become very hard to see one or two to five miles. Of course they must have jumped out 33
