Calls of a single bird overhead then pointed mic across the roosting flock.
Observasjonsdetaljer
*high | roost. Counted perched birds by tens in a single binocular view to approx 300, then counted around 25 of those views in the tree tops. Many birds streamed in after this count and at least 1.5x the initial visible group was seen when the birds started taking off from their pre-roost site. I have video of them streaming overhead after leaving the pre-roost and will compare estimates from that to this 12k count.
