Call of the Magpie

The magpies are in the yard! One does not have to see them to know they have arrived. At about 6:37 in the video, one of the magpies makes a winding sound, a bit like the Predator. Very cool (in my humble opinion). Also, early on a blue jay can be heard, I think, in order to scare the magpies away from the seed, cat food, and peanuts. However, the bigger black-billed magpies rule the pillars.
