So you’ve just begun your journey into the exciting world of birding, and you’ve been out on a few adventures on your own. Feeling a bit more confident and wanting to connect with your local birding community, you decide to attend a birding event—but you start hearing terms like “lifer,” “trash bird,” and “LBJ.” All of the sudden, your confidence flies away faster than a “nemesis bird” while your back is turned.
Not to worry! Every hobby has its own lingo, and birding is no different. Some words are self-explanatory, some a little more unique, and some are downright bizarre (what the hell is a “Patagonia Picnic Table Effect“?). So we’ve built this handy glossary of terms to help. While it might not help make you a successful birder, it’ll at least help you sound like one…

The phenomenon that occurs when a rare bird causes several birders to flock to a site, resulting in more interesting species being spotted in that same area.
