Equipped with computing power and advanced radar technology, we can begin to provide detailed data on avian activity in the atmosphere
The BirdCast team, along with other radar ornithologists, uses a broad array of tools to make sense of a treasure trove of information collected by radars about birds, such as migration density, flight speed, and direction. Our data are not complete, though. Many advances in radar technology have aided in our abilities to differentiate birds from r...
Dec 23, 2018 · It doesn't scare them per se, just alerts them a little sooner. In human terms, the effect is probably most comparable to tinnitus. However, the range of this effect is <200 ft, so a weather radar can't be relied on to prevent bird strikes. It's also not well-studied and not verified across a wide range of species.
