Silent migratories

["Colin Driscoll" <>]

Hi

It's easier to know when the migratory birds arrive in spring than to be
sure that they have left for the winter. A few weeks ago the Channel-billed
Cuckoos, Dollarbirds and Koel all fell silent, but were still around. I
think the CBC and Dollarbirds left this week but there was a pair of Koel
around Saturday. Interesting- I guess the hormones have settles down and
they are no longer territorial, so no longer need to advertise.

Cheers
