"All" lists all 380 species seen or heard.
"Exclude Exotics" lists the 376 non-Exotic species seen or heard.
"Include missed species (non-exotic)" lists 376 non-Exotic species along with the 15 species missed but observed in the state by others during 2022. This constitutes a complete list of all ABA-countable species recorded in eBird in Washington during 2022.
"Missed species only" lists the 15 non-Exotic species observed in the state by others but not by us.
"Seen once" lists the species which we observed only once, or at least recorded on only one checklist, during the year.
"Rare/difficult" lists the species which in Brian's opinion are either rare or not usually easy to find even in suitable habitat in the state. These, along with the "Seen once" species, are the ones to prioritize if doing a big year in Washington.
"Heard only" are the species which we identified by call or song but did not see.

"Heard only" indicates that neither of us saw the bird but were able to identify it by call or song.
"B Heard only" indicates that although Darchelle saw the bird, Brian only heard it.
"Photo by" with initials indicates that Brian included a photo by someone other than Darchelle in the journal entry, with attribution in the journal entry Itself.
"Id by D" indicates that Brian saw or heard the bird with Darchelle but not well enough to identify it. She described what she saw or heard at the time to Brian who confirmed her identification.
"Id by others" indicates that neither Darchelle nor Brian saw the bird well enough or at close enough range to identify it, but that other people (including spotters on the pelagic trip) viewing the same bird at the same time were able to identify it.
"Id by photos" describes a situation where Darchelle saw the bird through the spotting scope, identified it and got photos while Brian, watching without optics, was unable to distinguish the bird from others in the flock but was able to confirm its presence and identity from Darchelle's photos. Including these birds in Brian's list is a concession made because his disability prevents him from standing to look through the scope; he saw the bird but was unable to pick it out due to his inability to use optics.
