[TN-Bird] Re: Cicada

Since we're off-topic (sort of), here's a great website for cicada
information.  You can report sightings of the 17-year Cicadas to
a National Geographic Society sponsored study to map out the range
of this brood and help detect any changes in the population.  Two
broods of periodic cicadas are known to have gone extinct.  Also,
note that there are actually 4 species of 17-year Cicadas which
can be identified by their call.  The website has audio files
that you can listen to online to help ID the different species.
If you mine into the website a little bit, you will also find
similar pages for the annual cicadas.  I'm up to about 10-12
species for my cicada yardlist, all annual species... none of
the 17-year or the 13-year brood from a few years ago.
