A scope is pretty much essential at this location, as the vantage points are usually some distance from the waterfowl.

It is inadvisable to attempt to bird from the causeway or bridge, as there are no sidewalks, the roadbed is narrow, and the traffic is typically heavy and moves quickly. Instead, either scan from Anchor Bay Rd at CR 16/37 on the north side of the causeway or from beneath the bridge on the south side. To access this latter location, follow the car track which parallels the north side of CR 16 and leads down to the shore. Be very careful during winter visits to this vantage not to get too close to the shore, as it can be icy and very slippery and the current here is quite swift.

This site is known primarily for late-lingering waterfowl, like scoters, Long-tailed Duck, and Red-breasted Merganser, as well as loons and grebes. For a short period in spring large rafts of diving ducks congregate in the expanding ice-free channel both to the north and south of the causeway.

Gannon Narrows is notable as one of the few bodies of water remaining largely open during the winter months attracting variable numbers of waterfowl. The location is best in winter and during both fall freeze-up and spring breakup, as the swift current in Gannon Narrows maintains an ice-free channel when all surrounding waters are ice-covered. 

This hotspot covers the waters of Gannon Narrows within sight of the bridge/causeway. There is some overlap in coverage with the Fothergill Isle Causeway hotspot to the west, the Gannon Narrows CA hotspot to the south, and the John Earle Chase Memorial Park (south) hotspot to the north. If specifically birding in either of these latter two hotspots, please use them and not the Gannon Narrows (bridge/causeway) hotspot to record your observations.
