The bird will not starve. But the reason most people have bird feeders is not to keep birds from starving but to provide them with a food source so easy to access that they preferentially visit your yard. Feeders = birds in the yard. If you provide food for a bird you find interesting (because the current source such as a tree of berries is running low) in hopes of it sticking around a bit longer, great. Maybe the bird will. Point 2. I DO like Peterson more than Golden, for the drawings and the range maps (which are fairly up to date for most species). But I do not agree with getting the book just for "updated" species names. The new Golden has new names too... The lumping of species is a typically subjective judgement call made by a particular taxonomist: not all of us agree to any one of particular one of these `lumpings'. There are many avain taxomomists who do not recognize the lumpings done to Myrtles, or Juncos, or Baltimore Orioles (to name just three). For us, they are Myrtles. That there is a narrow hybrid zone does not change that. (If you feel it does, please note that the name changing has not been uniform or consistent: among others, Herring and Glaucous gulls freely hybridize in Iceland, and, by the same criteria they should be `lumped' into one species (take yet another species off your life list, please). The Myrtle Warbler may again regain its `official' status... as may the Baltimore Oriole and so on. -- Name: Richard Snell Mail: Dept. Zoology, Univ.
