Observation details
Rough estimate. Very numerous. Number based on having observed this migratory event on various evenings in the past during official counts, having those counts yield 18,000-22,000 birds depending on the evening. The number of birds tonight seemed roughly half of those larger numbered counts, hence the estimate of ~10,000 birds.
