Observation details
The dispersal from the roost began at 7:09 (sunrise - 7:49) and lasted for about 20 minutes. It occurred largely in seven waves (47-135 birds per wave). The first few waves were concentrated and headed off in fairly well defined directions. The later waves were less concentrated and less directional. The count is based on a review of 23 minutes of video. The posted video has been edited to three minutes and shows waves two through seven. A report on this roost site can be found in the fall 2022 issue of Blue Jay, published by Nature Saskatchewan (Patterson J., Jensen R, Blenkin C. Magpies roost at Saskatoon in record numbers, Blue Jay (2022), 80(3):12-13).
