Maryland contains a diversity of forested habitat including hemlock forests, loblolly pine woodlands, moist upland forests, dry upland forests and riparian forests. Hemlock forests support species such as barred owl, pileated woodpecker, veery, and Louisiana waterthrush. Western hemlock forests such as at Swallow Falls may also contain hermit thrush and black-throated green warbler. Loblolly pine woodlands lie on the Coastal Plain and can support species such as brown-headed nuthatch and pine warbler. Contiguous, moist upland forests throughout the state can support red-eyed vireo, wood thrush, and ovenbird. Larger dry upland forests may contain black-and-white warbler, scarlet tanager, and worm-eating warbler.
