Port Crescent State Park is Huron County's best known birding location. It is well known for observing raptors during their migration with a dedicated raptor observation deck. The park is also excellent for water birds and passerines. Its unique location at the tip of the Thumb means that good numbers of birds collect here in spring and fall. Snowy Egret, Prairie Warbler, Henslow's Sparrow, and Red Crossbill have been detected. More regular species of interest include Forster's Tern, Great Black-backed Gull (which may be seen year-round) and Glaucous Gulls (often lingering into late April and early May).
