Thousands of Cedar Waxwings Laughing

Thousands of Cedar Waxwings and other warblers flew overhead and through our trees ahead of an approaching cold front from the West early at dawn while I was walking the dogs. We stood along with the geese and listened to their laugh-like calls to each other http://www.allaboutbirds.org/guide/Cedar_waxwing/sounds 
as they flew fast through the pines and oaks down towards the South-East.
It was such a delight in the cold chilly stillness of the early morning.
