Hey Runner:
I manage for squirrels! At least on the dirt that I own! never have for any client,though,because like you say they all want deer and turkeys!
The limiting factor in squirrel populations is the lack of hollow trees providing suitable nesting cavities. Squirrels are a prey species, and are especially vunerable to birds of prey.Great Horned Owls by night and the female Coopers Hawk by day probably lead the list of squirrel predation!
I am in the process right now of making nesting boxes and hanging these in maturing hardwood stands on my place. Two per acre is the recommended density unless an abundance of natural cavities already exists, and this isn't probable unless the timberstand exceeds a hundred years in age! The leaf nests that you see in hardwood stands are bedding nests only, and usually of males and not females. Young may very rarely be born in leaf nests, but it's just that....very rarely!
As a rule in hardwood timber and mixed pine/hardwood stands, ample food material is usually there in abundance for squirrels. These animals do scoff up on mulberries,blackberries,gooseberries and all other soft mast species in season growing in the woods, but the bulk of the diet is leaf buds, tender young herbaceous buds and stems,and Protein items like big insects,small bird nestlings,bird's eges, small lizzards,frogs and even little snakes :shocked2: . About 15%-20% of a squirrels diet is protein.
Now this Thread is about squirrel hunting calibers, and I don't want to get strung out on turkeys,but I am forced to mention this: If you have any question or doubt about turkeys and their reactions to various colors, I urge you to read the available literature on wild turkey biological characteristics. In fact I beg,plead, and challange you to read a detailed study of young turkeys by a good friend of mine. The book is "Illumination In The Flatwoods-A season with the wild turkey" by Joe Hutto, ISBN-13: 978-1-59921-197-8. You will be a better (fully camoflouged) turkey hunter for your troubles :v .
