When you get to Northwest Hill Road, turn right. Then turn left after a few hundred feet, onto the dirt road that leads into Hopkins Forest. The entrance road takes you right into the forest, and right into a fine birding area. The ravine to your right harbors breeding Louisiana Waterthrushes and Winter Wrens , two of the finest songsters among all the birds in North America. At any point, be on the lookout for Northern Goshawk and Pileated Woodpecker , which breed in the forest and wander widely throughout.
Migrant warblers are especially easy to see here, where the vegetation is lower than in the forest.
Chestnut-sided Warblers are especially common breeders here. After a while, the habitat opens up a bit, and you'll come across a fairly substantial farm on your right. Bobolinks sing like crazy here, and you cannot miss them. It takes a little more patience to discern the thin, hissing songs of the Grasshopper and Savannah Sparrows that dwell here. I even saw Vesper Sparrows in migration, but I don't believe that they stick around to breed.
