Dana, Tweeters,

Thx for your reply. In our area the number of Mountain Bluebirds vs Western
seems to be directly proportional to altitude increase, the more altitude,
the more Moutain Blues.. Area I'm relating to is North Wenas road and (old
highway to Elensburg). One of the BB trails right on top of the ridge
normally has a ratio of 20 Mountain, out of 22 boxes. While the trail I
monitor is on the lower end and has only one mountain in 50 boxes..
