Their are several bird detection radar systems either in production or under development. Some outstanding work has been done with the hardware and software to provide bird species identification, flock number estimates and future flight path predictions.
What has not been developed yet is how the aviation industry will use this information. How will airports use it for strategic and tactical wildlife management? How will ATS providers use the information? How will pilots use the information?
Much like GPWS/EGPWS and windshear detection the challenge is figuring out how to practically and effectively integrate the available tools into the system.
In essence we are at the "proof of concept" and field trial stage in development. Our industry will need to devote resources to developing the processes to use the product output.
