Unbelievable spectacle. Immediately after the rain let up just after dawn, BLTE started to swarm over the north end of the lake in huge numbers. Clicked birds 10x1 in a single west-east scan from my scope point on the NW side of the lake, resulting in 3460, then kept a running clicker count of birds crossing the treeline from the north and dropping into the lake throughout the obs duration (357). Upon leaving, there were still at minimum 600 birds on the north side of the treeline roosting on the sandbar with shorebirds. Not sure if this count is in line with regular numbers from this site, or a product of migration timing, conditions, and local strong SE winds and precip pushing birds to the NE section of the lake. Either way, one of the most incredible things I’ve seen.
