I started birding five years ago, and the first thing that hit me was the vocabulary. Birders have a language all their own: “jizz” for overall impression, “pochard” instead of duck, “lifer” for a first-time sighting. My notebook filled up with scribbles, but I could never find the meaning of a term fast enough during a morning walk. Paper guides are great, but they don’t adapt to what you actually see in your local patch. That’s when I realized I needed something I could build myself – a living list of words, each tied to the birds I had photographed, heard, or just missed. So I started using dictac, an online tool that lets you create personal dictionaries. It felt like the perfect fit: I could add entries for species, behaviors, even local nicknames. No more flipping through pages or hunting through apps that assumed I lived in Florida when I actually watch chickadees in Manitoba.
What makes a custom dictionary better than buying another book? For one, you decide what goes in. My field guide has entries like “bufflehead – male has puffy head; female gray-brown with white cheek patch.” That’s not in any official guide because every birder describes things differently. I also include sound mnemonics: “wil-lee-wil-lee” for the killdeer’s call. Over time, this personal glossary became faster to consult than any app, and I remembered more because I had typed it myself.
Field guides are written for the whole continent. They show twenty similar warblers when you only have three in your backyard. A custom dictionary lets you focus on your region, your season, your life list. I started with ten species and now have over 130 entries. Each one is tied to a date, a location, or a funny story – like the time I confused a Cooper’s hawk with a sharp-shinned hawk for three hours. Writing down the key differences locked them into my memory.
You don’t need fancy taxonomy. Simple works best. For each bird, I write the common name, then one line about appearance (size, color pattern), one line about habitat (woods edge, marsh, open field), and one line about song or call (often a phonetic spelling). If I saw an unusual behavior – like a robin eating fermented berries – I add that too. The key is consistency. Keep every entry short enough to read while holding binoculars.
This method works because it forces you to pay attention. You cannot lazily call something “a little brown bird.” You have to describe it well enough that someone else could identify it from your words alone. Within three months of keeping my dictac glossary, my identification accuracy went from guessing half the time to being confident on eight out of ten sightings.
They rely on memory alone. I did that too. Then I spent twenty minutes watching a “sparrow” that turned out to be a song sparrow. A simple note could have saved me those twenty minutes. The other mistake is buying too many apps. You end up cross-checking two field guides plus Merlin plus eBird, and you still forget whether the yellow-rumped warbler has a yellow patch on its rump or its crown. One personal source cuts that noise. You trust what you wrote because you wrote it.
A custom dictionary does not have to be private. Some tools allow sharing. With dictac you can invite friends from your local birding club to contribute their own sightings and corrections. We built a shared glossary for our nearby nature reserve – everyone adds new birds they find there. Last week someone added a Lincoln’s sparrow that drifted off course during migration. That entry now sits alongside everyone’s notes on habitat and call. It’s more alive than any printed book could be.
The real power shows up when you look back after two years. Your dictionary becomes a diary of where you went, what you saw, how your skills changed. I see my early notes: “red-tailed hawk – large, red tail” next to recent ones: “red-tailed hawk – dark morph adult; heard distinctive raspy scream before seeing silhouette against cliff face.” The difference tells me how much closer I look now. And all of it lives inside something I built myself, not hidden inside some corporate app that might vanish next year.
