Things to See While You’re Leaf Peeping

During your foray to view the colorful foliage of the autumn landscape, a little effort will reveal much more than meets the eye of the casual observer.

Fallen Foliage in the Forest
Don’t just stand there like a bump on a log, go for a stroll, watch your step, and have a look around.  There’s a lot to see out there!
Witch-hazel
The dense understory of this forest on Blue Mountain consists almost exclusively of Witch-hazel (Hamamelis virginiana).
Witch-hazel in Flower
Witch-hazel is unique among our native flowering shrubs; it blooms in autumn.
Common Buckeye
Until we experience a heavy frost, some of our most beautiful butterflies, including this Common Buckeye, remain active along forest edges.

Yellow-rumped Warbler
The arrival of large numbers of Yellow-rumped Warblers heralds the transition to movements of migrants that will spend the colder months in temperate climates like ours instead of continuing on to the tropics.  In winter, small numbers of “yellow-rumps” sometimes linger in the Lower Susquehanna River Watershed, as long as a supply of wild berries is readily available.
Palm Warbler
The Palm Warbler, a persistent “tail wagger”, is another late-season migrant that occasionally spends the winter.  The migration of these drab “Western Palm Warblers” will be followed in coming weeks by the more yellowish “Eastern Palm Warblers” of the eastern third of the species’ breeding range in Canada.
White-throated Sparrow
White-throated Sparrows are southbound and easily observed right now.  Many will remain along our brushy forest edges for winter.
Dark-eyed Junco
Another native sparrow, the familiar Dark-eyed Junco, is now arriving.
Yellow-bellied Sapsuckers
The Yellow-bellied Sapsucker is a secretive migratory woodpecker that is currently moving through the region on its way to southern pine forests for the winter.  Juveniles like this one in the lower right remain close to their parents during migration and continue to beg for food.
Pileated Woodpecker
The Pileated Woodpecker is a resident species in our mature forests and woodlands.  We were showered by “sawdust” as we watched this one dismantling a rotted dead tree while searching for beetle grubs and other invertebrates.
Eastern Bluebird
You may see Eastern Bluebirds year-round in the lower Susquehanna valley, but many are migratory.  A southbound push is currently transiting our area.
