These birds are called black grouse. Taste them again. About one day need to marinate, better in dry wine. After that it will be more or less acceptable taste. However, in the Internet there is a lot of recipes for these birds, another question is that they are difficult to obtain )))
In Scotland there is an on-steroids mega version of these called Capercaillie. The Canadian version is called Spruce Grouse or 'fool hen' by those that have dealt with them before. I tried to live off these one fall in n. Ontario 10 years ago but to be honest they taste much like the trees they were sitting under (black spruce). Ruffed Grouse on the other hand are quite tasty but were not common up there. I don't suppose you guys stand on the upside down dead bird's wings right at the 'armpit' and pull up hard on both legs to clean them? Pretty simple and effective method that leaves you holding two legs and the breast without muss or fuss.
I cleaned over 20 animals last year between what I shot, wife, friends, and helping with a hunt, and more the year before.
Phil Wilson in K294 is by far my favorite, and was used on almost all of them. Great design, great edge retention, and easy to sharpen.
If it is within the budget, I would highly recommend Phil Wilson as first choice.
The Dozier is excellent, and outstanding value. Really love the feel of this in hand. It is very comfortable. It takes a razor sharp edge, and holds it quite well.
Ingrams are beautiful, and work very well also.
Sold the Spey last year, wish I would not have, but replaced it with a Phil Wilson.
My Busse Active Duty has dressed more deer than I can remember, but I used an Izula2 this year just to see how it would do. Did fine, but I prefer a bit more blade. I will probably try my Moran Drop Point next. Mora 780 Craftsman handles butchering duty quite well and has for several years.
As an UPDATE, the Active Duty is my favorite and is my go-to knife, and will always be the first I reach for. It is the perfect size and comfort, and with the edge thinned, is a great slicer.
I traded an old compound bow for it. Custom made to my exact specifications and it works well for everything from squirrel to deer:
