I work with satellite water vapor loop, and close in radar as well as NOAA. The direction of the echo returns, where they appear and the direction they take, appearing and disappearing all lead to details for interpretation. No water vapor return and no close in rain radar rule out water returns. I ignore the typical blue ground clutter return around Miami and Ft. Lauderdale. But large "returns" what ever color that move south to north with 15 minute intervals has always proven to me to be birds. At Barbirdz2 you can (when the owner is home) actually watch the birds rise and descend. It is a "tool"..no infallible but worthy of watching once in a while.
Bad Birdz2 is a good location for technical details:

This high wind today will be tough for the birds that aren't flying. The dove at my feeders can hardly hold on.
