Flight calls before dawn

Published by at 8:49 am under Migration

Back home in Pittsburgh the weather feels like Maine but sunrise is much later.

This morning I had more than an hour before dawn to sip coffee on my front porch and listen to the birds fly by in the dark.  Most of the migrants sounded like spring peepers but I heard a few mystery birds mixed in.  What were they?

The spring peeper call is made by Swainson's thrushes.  To figure out the mystery birds I listened to the sounds on this blog by Paul Driver

Did I find out what they were?  Well, no.  My audio memory is not very accurate. 

The birds remained a mystery, as do those in the photograph above.

    Wow, that blog by Paul Driver is quite interesting. Thanks for the pointer.

    I’m thinking “some kind of thrush” for the silhouetted birds above.

    And, they have a bit of corvid to them too. That’s my second guess. (I know we’ll never know, I’m just bored here at work today…)
