Birds on BoM Doppler wind radar?

[Dominic Funnell <>]

Back in the late 80s when carrying out surveys on migrating raptors in Israel 
large flocks of birds were often seen on airforce radars and then ground 
truthed by surveyors on the ground. I remember seeing large flocks of European 
Honey Buzzard that way.
I also have a recollection that the Rothamstead Institute I think it was looked 
at whether migrating butterflies could be picked up using radar.
