One quail makes at least two robins here on the east coastal plain. As far as flavor, a wild critter that lives on a vegetation diet taste better. As rodent goes, rabbit, squirrel, muskrat or groundhog are much better than norwegian (brown) rat. Raccoon, 'possum, and such other small critters if from the wilds, and not from town, do not taste bad, if a little gammy. I bet robins taste after the worms they eat. I rather a dove, rock or mourning, but not from city streets. Most of these small wild birds, even ducks, are not much more than the breast portion. A quick slice through the skin and very easy to dress.
We turn rocks in a fresh water stream to find crawdads to boil, might as well eat beetles. Although the crawdads do have a meaty tail.
Down the shore collect some mussels and steam them up. Just be sure of the water quality. Cape May Point good, Atlantic City bad. Fresh mussels are soooo much better than found in even the best restaurant.
