Hi All, Yesterday morning, 13 August, four minutes before civil sunrise at 0551 hours (0852 UTC,) in Carleton, Nova Scotia, I recorded what appears to be a fall-out of American Redstarts (AMRE) and Black-and-White Warblers (BAWW). In the space of 1 minute and 20 seconds, there were 21 American Redstart calls and 39 Black-and-White Warbler calls, plus an Ovenbird (OVEN), and a few unidentified warblers. A screen-capture of my Raven Pro review panel is attached and shows the calls for this 1.33-minute period. Please note that there are a few duplicate clips in the photo for those cases where calls were overlapping.
I should note that an air quality warning was in effect in the areas just northeast of my monitoring station due to a number of wildfires. There was a light shower at the station between 0130 and 0157 hours. Otherwise, there appeared to be no other unusual atmospheric conditions. While it is possible that this was a flock of birds already on the ground and moving with first light, the pattern of calls is similar to what I've seen before for autumn fall-outs of warblers, usually much later in the season, in mid-September.
