Flight started at 6:50 and quickly built to the point that there were nearly constant flocks going by until 7:15 when it slowed dramatically. (Count at 1480 at this time). Several flocks of over 100 birds (max was 230!). Pretty major lull with almost no movement at 7:15 but flight picked back up in earnest at 7:35 (1568 prior to flight picking back up). Slowed again around 7:55 (Count at 2680) but had a few very small flocks afterwards until 8:05. Nothing after that.
