You're probably seeing many young European Starlings in your yard this time of year.

This little fluffball is a juvenile Green Heron. It hatched from an egg only a few weeks ago, in a stick nest built on a tree branch overhanging a shallow wetland.

Fall migration is underway, and some of the earliest migrants are shorebirds like these Least Sandpipers I found last week. 

I've been enjoying seeing a fledgling Red-bellied Woodpecker visiting my feeders during the last two weeks.

The slurred whistles of the Louisiana Waterthrush are quite loud so that other waterthrushes can hear them over the constant noise of water rushing over rocks.

Red Crossbills are one of Pennsylvania's least studied breeding birds.  To find nesting crossbills, you usually need to head north.
