Lets go a little further with this Covert information.
In the big woods there can be many different grouse Covert
locations depending on the size of the mountain you are hunting. For example a mountian that is 10 or more miles long can have 10 - 20 Grouse covert location on it, depending on how much the coverts over lap with each other.
Thru the years the RGS/PGC Grouse reasearch projects have identified approximate
area sizes of Grouse coverts, however in reality these covert areas can vary greatly depending on habitat food mass and predators. However once a hunter finds a long term covert area, unless something drastic happens it will
remain in that general 1 mile location until the forest changes, and if there is logging to keep the forest in constant regrowth the coverts will remain for darn near ever. In the big forest with all the side logging roads and Deer paths Grouse can flourish, remember Grouse are edge birds and live, feed and reproduce on these edges in the big forest, especially with downed trees for drumbing sights. On just one of our mountains in my home area there
are over 20 different active covert locations, in some of these coverts there are as many as 30 Grouse, not many times here in Pa do you get to see most of the birds in one area however, Pa has way to may predators unfortunately. However if you put in your time, God rewards you when you least expect it. My buddy Ken on his very 1st Grouse hunt witnessed over 30 Grouse grouped together along one of our big logging roads, and taking a wall hanger of a Grouse he needless to say, is hooked on Grouse hunting for ever, he now has his own young Gordon Grouse dog, and returns to hunt with us each season. The more prime habitat in the big forest the more covert locations develop and the more the Grouse population expands. Having helped with both the old RGS/PGC study here in Potter County and the one in Somerset County also, it is my opinion that Grouse Coverts flourish best in large well managed forests. This is why in the late 1800 to about 1906 our Grouse population here in Pa was just incredible, our big forests were in all the different growth stages and constantly logging was being done, and flying predators were being shot on sight, safe guarding our small game populations. Pa's Grouse limit was 10 birds a day, because covert locations were able to develop every where thru out the big forests. Unfortunately for the Pa Grouse hunter forest mismanagement and illegal federal treaties have drastically changed Pa's Grouse population today.
