My favorite
binocular for
warblers is a 7x or 8x model with a healthy field of view, though an excessively large field of view is not something I require. In this regard, the
Nikon Premier 8x32 SE is ideal. A wide field just makes it easier to keep up with birds as they bounce from branch to branch. I also like lower magnification binoculars for their steadiness and, with this type of birding, I rarely have the option to brace the
binocular against a convenient tree branch or other object. Hey, at my age, it is getting tougher to steady a 10x
binocular. I save my 10x binoculars for the marsh, where I can sit comfortably and brace them against my knees.
