Feeding junior.



This yellow warbler was feeding a cowbird chick. 

The yellow had been a victim of “brood parasite” by a brown headed cowbird.

The Brown-headed Cowbird is North America’s most common “brood parasite.” A female cowbird makes no nest of her own, but instead lays her eggs in the nests of other bird species, who then raise the young cowbirds.

This large clutch size may allow Cape May Warbler populations to expand rapidly during outbreaks of their preferred prey, spruce budworms.

Folded rocks.

This formation is also called the Faults & Folds of West Bay Beach. "The folds of rock are related to the churning tectonic activity that gave rise to the earth's mantle hundreds of millions of year ago." For scale I am about 6 feet tall.
