Proof of this phenomenon was posted recently by the Corolla Wild Horse Fund: a photo of a horse named Amadeo Jr. ambling around with a 2-foot-tall cattle egret on its back. More egrets can be seen ...

This striking cattle egret, all decked out in its breeding plumage, was checking out a nesting site at the rookery in the Village of DeLuna. Thanks to Julie Walfield for sharing!
