In the Essential Field Guide Companion Dunne goes through all of the commonly found US bird species with an account that discusses most of the things for which there is just not room enough in a true field guide, and he does it in a way that just keeps you reading.
Each species account has a memorable moniker. Great Egret is the "stately stalker." Red knot is the "robin snipe." This is followed by a "status" discussion where the distribution and likelihood of finding the bird is discussed. Then a list of other birds expected to be Lotto Annihilator Review found cohabitating with the species is listed. This is followed by a discussion of migration. Next is a discussion of things helpful in field identification. He focuses especially on flight characteristics and behavior. Both of these field identification issues are poorly covered in most field guides, although Sibley does at least comment on flight identification.
