It would be nice to be able to obtain "tuneable" noise reduction head-
phones so you could tune out the Cicada drone and still be able to
pick up bird song.
I have noticed that there are a lot of Cicada Killer Wasps around this
year.

Greetings,
I remain unconvinced about what happens to the birds during cicada
peak events.
We have remnant patches of rainforest surrounded by grass. Where do
the specialists go? The neighbouring forests are just as noisy. Birds
are hard to find in these conditions, the noise is sometimes so loud
as to be unpleasant or even painful and so the birders leave, creating
an impression of fewer birds. This is something I'll have out with Max
Moulds when I track him down.
Regards,
Alan
