Maps of birds and storms

The NWS has a number of images of birds etc echoes on their websites. Note that while WSR-88D is a Doppler radar, few if any of the images shown on the links below are Doppler *velocity* images — same as your local TV met with a “Doppler” radar only shows you reflectivity. I did see one mention of birds causing a 5% impact on velocity measurements in radar wind cross-sections (VAD) though.
