the minus broadwing and turkey vulture test

The columns labeled AF Gage, Koban and AF Dick indicate the counts were made at several different properties through the years. Gage, Koban and Dick are the owners of those properties which are located close to one another. However, the views to the west are different at each site and that factor limits comparisons between the different sites' counts. The normal two letter designations are used for the different species to reduce space in the table. BW = Black Vulture, TV = Turkey Vulture, OS = Osprey, BE = Bald Eagle, NH = Northern Harrier, SS = Sharp-shinned Hawk, CH = Cooper's Hawk, NG = Northern Goshawk, RS = Red-shouldered Hawk, BW = Broad-winged Hawk, RT = Red-tailed Hawk, RL = Rough-legged Hawk, GE = Golden Eagle, AK = American Kestrel, ML = Merlin, PG = Peregrine Falcon, UA = Unidentified Accipiter, UB = Unidentified Buteo, UF = Unidentifed Falcon, UE = Unidentified Eagle and UR = Unidentified Raptor.
