Migration Radar experimental
What weather radar saw aloft overnight on the upstream approaches to Loess Bluffs — regional bird movement, a leading indicator of migration. Not a count of birds at the refuge. Pick a night to see which stations lit up, and how the birds were moving.

Built from weather-radar vertical profiles (~5-min scans). Density, altitude, and direction are observed; nothing here predicts arrivals at Loess. One partial season — relationships are unproven.
