Over and again, Kroodsma admits to things to which neither he, nor any other researchers, yet have answers – including areas where diligent amateurs can, he says, make discoveries. Good field guides to bird sounds are certainly available, particularly Nathan Pieplow’s for eastern and western North America.)

The majority of wildcats live today in Africa, and virtually none of them have provided the DNA from which supposed histories of domestication have been constructed by researchers. But they don’t live in North America. I find it astonishing that people argue of whether feral cats are bad for birds in North America.

It’s the warbler that is often the last unchecked species on birders’ life lists and, whether you list or not, for most of us observing it is a once in a lifetime experience. Previously, even researchers had problems getting access to nesting Kirtland’s Warblers. Now there are volunteer guides, tours and a local festival.

What are the best field guides for birds in North America? Many birders keep personal birding lists or life lists, documenting the species they have seen throughout their birding experiences. Encountering a spark bird is a transformative experience for many birders. What is a “nemesis bird” in birding?

One question at the heart of this debate is how these four populations (Mallard, American Black, Mottled, and Mexican Ducks) came to occur in North America. A hypothesis by some genetic researchers states that the green-headed Mallard arrived in North America after a prior colonization that had given rise to the other three species.
