One that says "honk, eh?"

First one needs to consider what the criteria are for "countability." When a young birder starts off, his list may include these birds: robin, hawk, Canadian Goose duck, and "Yellow-billed Loon," identified by a stranger and viewed through his Aunt's scope. That is a personal list and quite valid. It's a first step to becoming a birder, and many of us have done that in the misspent days of our youth. And a birder of any age can keep a list of any kind. I have friends who keep a list of all birds they have seen in Colorado, including at the Zoo! But once a birder gets to the stage of wanting to compare his own list to other birders' lists, and maintain a reputation, the question comes up, "Can I count it?" In other words, "What are the rules of this game?" and "Do other birders include that species on their lists?" Let's face it, "The Lure of the List" is strong, and many birders have a gene for competition. Some disparage "listers," but there are few experienced birders who do not keep lists. And there are "mental lists." I have found that if a birder disparages "listers," they can usually tell you what birds they have seen, thanks to their mental list. Most of us follow the rule that the Colorado Field Ornithologists set down some years ago: For purposes of comparing one's state and county lists to those of other birders, the bird must be on the official Colorado list. http://coloradocountybirding.org/Checklists.aspx That applies to state lists, year lists, county lists, etc. Mute Swan, Graylag Goose, Monk Parakeet are not on the official CO list and most of us don't include them on our lists. That way I can be sure my list has not been "padded" by exotics. That official CFO list has been generated over the decades by expert volunteers on the Colorado Birds Record Committee, and it's maintained with care and scientific judgement. The CBRC went to great lengths (stable isotope analysis) to conclude that a taxidermy mount of an Emperor Goose shot in Colorado was probably not of wild origin. It's important that our state list is a "clean" one. Then it's comparable to the lists from other states, for example. And the fine points of what birds are countable are spelled out by the American Birding Association (ABA): http://listing.aba.org/aba-recording-rules/ There you'll find obvious guidelines like, "Don't count roadkill. Don't count birds in cages." And there you'll find some fine points such as, "When a bird has been caught in a net and banded, how many net marks must fade before you can count it?" eBird wants us to document exotics to watch for trends and changes. Witness the multitude of exotic cage birds, parrots and parakeets, that are alive, breeding and well in Miami, for example. So in summary, yes, report exotics to eBird, but when you do, the totals shown there on county or state or year lists, etc are not really comparable to others, who may have boldly gone into the field counting every Mandarin Duck and Jungle Fowl out there. You only have one chance to lose your reputation.
