Observation details
Estimate by tens, counted in flight, early in the survey in reach 4. I had several opportunities to count the flock this way, corroborating my estimate (consistently getting around 300). There may have been more, as the whole flock was not necessarily in the air/visible at the same time interval. I counted a sample of 50 birds perched along the creek, of which 44 were grayish juveniles and the other 6 were adult-aspect birds. I saw the large flock only in the eastern part of the transect early; I saw groups of 10-30 in flight along the creek corridor numerous times later in the morning.
