On May 2, Harry LeGrand said the following: " One Swainson's is seldom if ever going to be within hearing range of another, at least certainly not within about 75-100 yards, as in the case here."
-- I cannot speak to Swainson's Warbler habits in the North Carolina Piedmont, but that statement is most untrue if applied to Swainson's Warblers in Lowcountry South Carolina. Especially early in their breeding season before the pecking order gets worked out.
I have seen (and heard) two males chase each other NUMEROUS times and have seen well-spaced "conga lines" of 3 and once 4 birds in prime sought-after habitat.
In the mountains, I have also seen two male Swainson's Warblers fairly close to each other - facing off and working on territorial boundaries in thickets along the Green River in Polk County, NC.

I was there this morning, hearing and seeing the SINGLE singing bird as our group headed downriver around 745, and again just the one bird coming back around 1030. The other bird singing at bridges 288 and 289 is a Louisiana Waterthrush, not a second Swainson's. (I note a few of these lists don't even list Louisiana Waterthrush; today, there were about 4-5 singing LA Waterthrushes along the greenway for about 2 miles downriver of the parking lot; but just one Swainson's Warbler.) > > Swainson's Warbler are very strongly territorial and charge a song of another bird, as witnessed by the many times over the years I and others have played tapes. So, if there ever were a second singing bird within hearing range of another, one would have driven off the other immediately. One Swainson's is seldom if ever going to be within hearing range of another, at least certainly not within about 75-100 yards, as in the case here. > > So -- eBird editors, there is/was only ONE singing Swainson's Warbler along this trail today (May 2). Of course, there could be a female nearby, but there are not TWO singing birds within earshot of each other. That probably also applies to yesterday's report of 2 singing birds as well. > > But -- yes, there IS indeed a Swainson's Warbler there, singing very close to the greenway trail, and you might well be able to see him without the use of a tape. He is clearly on territory.
