You're right about the counting part. I feel uneasy when I'm not sure about ID, from either a bad or fast view. For example, when I saw a kettle of Hawks above the Costa Rican rainforest, I counted Broad-winged Hawk only on my "Hypothetical" list, even though there were likely individuals of that species in the kettle. Also, I counted a gray fork-tailed tyrannid on a wire in Costa Rica as a hypothetical Scissor-tailed Flycatcher, based on probability at that location and seasonal abundance only.
I am quite certain that they were swifts; the thin- and crescent-winged silhouette is distinctive to me. However, I did not get a photo, and I did not distinguish the white throat. But I counted them as White-throated, based on probability, location and seasonal abundance.
Fortunately, today at 11:10 AM I saw a swift swooping under High Bridge in Spokane, in a place where they are known to nest, and there were 12 birds reported there this week. I saw the large size and long wings, lighter-colored back, and maybe even a glimpse of the white sides! So I'm sure of THAT one as being a White-throated, at least!

Was your first encounter with your swifts through the sunroof while driving? Did you see it's white throat? Did you get a picture? Swallows can fly like swifts at times-though totally different sillohoutte.

>> Good afternoon,
>> Today I took a nice walk along the Spokane River, starting in Riverfront Park. Walking along the riverside path, near the SW corner of the Gonzaga campus, I spotted two swifts over the next rise. It was only a three-second flash, but I saw the birds' thin, crescent-shaped wings flapping rapidly as they circled back and out of sight.
>> I sprinted ahead to try and find them again, startling three marmots along the river. I stopped to take a look at the marmots (my first sighting ever!) and the swifts were long gone when I started up again a minute later.
>> Question is, can I call them White-throateds with certainty? I did see your report of them on the campus from Thursday. I only was able to tell that they were swifts, but not identify them to species!
>> That makes me two for two of brief White-throated Swift sightings, both of them in pairs! My first encounter came only this past Monday, looking through the sunroof from the passenger seat as we left Frenchman Coulee.
