So, fun fact: birds and insects show up on radar. Often. As in, pretty much every day. Can we visually delineate between migrating birds and insects on radar? Usually. Here is a bumbling threaded attempt to show some telltale signs of each using the last 24 hours of radar data. First off, some caveats. We’ll focus on daytime and nighttime signals. At dawn and dusk the airspace basically turns into a veritable thunderdome. All kinds of things are taking flight and landing. Taxa are mixing together. It is chaos. We’ll mostly ignore dawn and dusk.
