Hi,

At least here in Finland dense Autumn migration has been analyzed from
weather radar images afterwards. Especially large amounts of nighttime
migration could otherwise be difficult to confirm without the information
from the radar recordings. On the other hand, the radar information does
not give any info on the species diversity or actual quantities of the
birds, so it's mostly nice-to-know data. And yes, it helps to have a
birdwatcher work for the Finnish Metheorological Institute.

BTW, regarding the mentioned bats. Although this particular "anomaly" did
not concern birds or bats, my colleague Markku made a sighting of over 500
Fruit Bats, presumably Little Red Flying Fox according to a local expert,
flying over Parkes towards West last week just around sunset. Don't know if
that's of interest to anyone or if it is common there, but at least it's
now here in the open.

Cheers from snowy Finland,
-Harry
