Ohio is bordered by Michigan, Pennsylvania, West Virginia, Kentucky, and Indiana. There are a number of Ohio eBird hotspots located near a state line. It is helpful to know where the state line is located so that the birds will be assigned to the proper state.
This is a list of locations in Ohio where the state line passes near an eBird hotspot.
eBird has a help article on eBirding along County, State, and Country borders with suggestions of how to handle your checklists when you are watching birds near a border.
Michigan State Line
Toledo Memorial Park
All of the developed section of Toledo Memorial Park, located north of Toledo, is in Ohio. The northern, undeveloped section of this cemetery is in Michigan. A hotspot has not been established for this northern section of the cemetery.
149th Street, Point Place
This hotspot is the northernmost location in Ohio on the Point Place peninsula. The northern tip of the peninsula is in Michigan. While there is an eBird hotspot in Michigan at the tip of the peninsula, Lost Peninsula, the road is a private, gated drive with access limited to residents and their guests.
Pennsylvania State Line
Pymatuning State Park
The Pymatuning Reservoir is on the Ohio-Pennsylvania border and is served by a state park in each state. For the convenience of birders, the hotspots in both states are referenced on the page link above.
The Ohio River forms the Ohio border with two states, West Virginia and Kentucky.
Since the late 1700s, various states have claimed ownership of various stretches of the Ohio River. The principal reason was to garner wealth from the trade that occurred on the river. In 1792, the federal government determined that Kentucky owned the Ohio River along its border with Ohio, Indiana, and Illinois. In essence, the boundary between Kentucky and these three future states would be the low point of the Ohio River’s northernmost bank.
Both Indiana and Ohio have sought to claim the Ohio River, despite the federal government’s declaration in 1792. In 1966, Ohio claimed that the Ohio River’s course had fluctuated since 1792, so that the low point of the Ohio River’s northernmost bank in 1792 actually would be near the south bank of the river today. Ohio asked the United States Supreme Court to give ownership of the river to Ohio or, at the bare minimum, to set the boundary between Kentucky and Ohio in the midpoint of the Ohio River. The Supreme Court ruled that Kentucky had legal ownership to the Ohio River.
From Ohio History Central
The area of the Ohio River that borders West Virginia, and the islands that located within it, are wholly owned by West Virginia, the deed of cession of the Northwest Territory fixing the low water mark on the Ohio side as the western boundary of (what was then) Virginia. More than 30 West Virginia communities extend along the river.
From The West Virginia Cyclopedia
Because of these ownership concerns, in most places the state line is very near the Ohio side of the river and birds seen out in the river are not physically in Ohio. eBird allows birders to decide which birds “count” for their state list and, as indicated in the help article above, it is permissible in eBird to record all the birds you can observe from a location. Bird record committees, on the other hand, usually want the bird to be physically located in the state. Birders who report rare bird sightings may want to keep this in mind as they prepare eBird checklists.
West Virginia State Line
While there are many hotspots on the Ohio side of the river along the West Virginia border, there are just a few where there are hotspots established on both sides of the river.
Pike Island Lock and Dam
The Ohio-West Virginia border is near the Ohio side of the Ohio River at this location. There are separate hotspots in West Virginia for reporting birds seen in the river pool or at the Pike Island Dam.
The locks at the Hannibal Dam are on the Ohio side of the river and the state line runs along the middle of the locks area. There is a hotspot on the West Virginia side of the river.
The state line is 20-40 yards out in the river from the Ohio shoreline. If you take the ferry to Sisterville you cross the state line at the beginning of the crossing. There is currently no hotspot in West Virginia.
Belleville Locks and Dam
There are hotspots on each side of the river for the Belleville Locks and Dam.
Gallipolis Locks and Dam
There are hotspots on each side of the river for the Gallipolis Locks and Dam.
Kentucky State Line
There are hotspots on each side of the river for the Meldahl Locks and Dam.
Indiana State Line
At this time, there are no hotspots established along the Ohio-Indiana border.
