OMG. I was an early arival party for a winter weekend in Cercedilla (our little house is not winter proof and we have determined best to only go when sunny) and I was sitting on the front porch enjoying the sun going down (and its warmth because inside the house is low 50s) and suddenly I saw three iberian magpies in a leafless tree enjoying the sun as well. I pulled out my binoculars and was admiring them and suddenly there was one on every branch, then I realized there was a low hum of bird calls and there were like a 50 of them flying towards the setting sun!!!! Crazy cool!
