38 Ogden Bay

Description

We surveyed the open water area of the bay between Antelope Island State Park causeway to the south and the railroad causeway to the north. WBS areas bound Ogden Bay to the east (areas 19, 20, 21, and 22); and lines connecting Promontory Point, Fremont Island, and Antelope Island bound this area to the west. The survey was done from an airplane in east-west running transects spaced one mile apart. Observers counted birds on both sides of the plane out to 1/8 mile. To extrapolate to the whole area, transect counts were multiplied by four. This area provides public access.

Detection Rates

It is difficult to count and identify birds while flying at speeds of 80+ mph. It is also very difficult to see small birds. Survey accuracy in this important area is not good. An observer counts out 1/8 mile on either side of the plane.
