Seemingly every town's cathedral has at least one stork nest. Nearly impossible to photograph with dinky ole iPhone, but super awesome to watch. Many (most?) have babies within them. The parents take turns with the babes. When one returns to the nest they make a racket and rub necks. (Is this where the term "necking" comes from?)
