Moro Cojo Slough is a shallow, slow-moving slough, south of Elkhorn Slough, that empties into south end of Moss Landing harbor. The Slough is protected by a State Marine Reserve (see map), but it is surrounded primarily by either private agricultural land or Elkhorn Slough Foundation protected property. Either way, except for researchers with permits from landowners, that is very little access to birders.

The primary viewing location is simply a wide shoulder along the south edge of Dolan Road, just about opposite to the entrance road to Moonglow Dairy at 537 Dolan Road, but slightly east.  On the map showing the Hotspot boundaries (in red), that location is at where the word "Dolan Road" appears for the 4th (and final) time, east from its intersection with Highway 1. A scope is very useful to see all the waterfowl in the slough, the waders at the edges, or the geese and blackbirds in the fields.

This Hotspot is primarily known for the presence of scarce geese among the flocks of non-native Canada Geese that forage in the fields south of Dolan Road, stretching down to Moro Cojo Slough itself, and present sometime on the south side of the Slough (a scope definately needed for them). Between October and April, various migrant and wintering geese are often here in small numbers. These are typically Cackling, Greater White-fronted, Snow and/or Ross's Geese.  Sometimes all these species are present but also it is not unusual for find none at all. Black-necked Stilt, American Wigeon, and Green-winged Teal winter in the slough, and the marshes are hunting by American Kestrel, Northern Harrier, White-tailed Kite, Loggerhead Shrike, and (at dawn or dusk) sometimes even Short-eared Owl. Red-tailed Hawk is present year-round, but the occasional Ferruginous, Rough-legged, or Golden Eagle have occurred in fall or winter (and Swainson's Hawk very rarely in migration). White-faced Ibis is becoming more regular in fall and winter, but just a few. The blackbird flocks may include Tricolored Blackbird.

Because access and viewing points to this Hotspot is limited to the edge of Dolan Road —an often busy road with fast drivers —once must exercise caution in pulling off and parking on the verge, off the roadway. There is not much space to set up a scope. Viewing is best in the morning and worst in the afternoon when the sun is against you.
