Yeah, it’s quite out of range - thus my surprise/disbelief!
I’ve seen many hundreds of Gull-billed in southern US states and Latin America ... just wasn’t expecting it here.
No additional sightings today. Surveyed on McTucker this AM (only Forster’s & Caspian plus Ring-billed & Franklin’s gulls) & just spent 20 minutes at Am Falls dam - no terns, just Ring-billed & Franklin’s gulls and a surprise male RB Merganser 😁

well geeeze, I see a couple of nearby reports in eBird, like.......
San Francisco CA, a mere 700 mi LOS, but can a GBTE fly a straight line? ;-)
Liberal KS, a mere 800 miles LOS, if it flew straight
intriguing.... but does the person reporting have much experience with GBTE, like with their flight pattern and foraging strategy...?

Subject: [IBLE] (Im)possible Gull-billed Tern at upper end of American Falls reservoir ...
A torturous one here... I’m helping the Intermountain Bird Observatory YB Cuckoo survey crew and last night ~815pm we were on McTucker Island when I saw a medium-sized tern with a thick black bill flew by heading downriver towards the reservoir. More description in this eBird list - I have it under “tern sp.” as I’m struggling to believe it myself but I can’t make it into any other tern species \uD83E\uDD14\uD83E\uDD14. Back on McTucker now & just had 3 Forster’s - a very different look & build.
I’ll plan to look above and below the dam tomorrow after surveys and before heading back to Boise & figured I’d post this looooong shot for anyone birding the area to keep their eyes peeled.
Based on plumage, it was most similar to a non-breeding adult in Sibley - only some small dark “ear” patches, not a full black cap.
