The Canada Goose has long been a recognizable member of the waterfowl flotilla bobbing up and down on Maryland’s many lakes, rivers and ponds. From early childhood we are taught about the winter migration of waterfowl “flying South for the winter” and back North to lay and hatch their young.
As the years past and the occasional nesting pair became nesting flocks, one couldn’t help but wonder if the popular saying failed to make its way to the geese. Year round populations of geese have become a common occurrence in Maryland, going from neat to nuisance for many citizens.
The Resident Goose:
This new emergence of non-migrating geese have created a new term in the wildlife management community, the now infamous “Resident Goose”. These resident geese do just that, reside year round on area water bodies, lawns, golf courses and crop fields. If unharrased, they often roost in the same place night after night and utilize food sources in the immediate area day after day. With a mature goose defecating nearly a pound a day, the damage begins to mount in those areas. Problems including high nitrogen levels in water bodies, damage to crops, landscapes and ball fields from overgrazing, as well as the health hazards attributed to human interaction with their waste.
These geese begin nesting in late February and March with eggs hatching sometime in late April. Average clutch sizes range from 3-6 eggs with females reproducing after 2-3 years of age and sometimes getting very aggressive in defense of their nests during this time period. Sometime in late June to mid July these geese go through a 4-6 week molting period in which they lose their flight feathers and are stuck to the ground with the rest of us. This process goes on year after year with potential ages of resident geese reaching sometimes over 20 years.
These older resident geese have become very wise to the tricks of the hunting community, taking up residence often in uphuntable areas within the urban fringe. Golf course ponds, homeowners association stormwater management areas, local government water features and even tops of buildings often become preferred habitat; see attached video below.
Management Options:
There are a multitude of available management options that may be able to address your individual goose issues, not all of them work as advertised, but non-the-less some do work. Your basic goose control methods are broken down into the following:
- Harassment (dogs, people, sound cannons, etc.)
- Exclusion (Habitat modification, fence construction)
- Repellents
- Lethal (hunting, flightless round-up, egg addling)
Resident goose management can be a very complex and delicate issue, an issue which is just now beginning to make its way to the level currently experienced by suburban deer managers. An entire article can be written on each of the above methods, and we will most likely get into them more in the near future.
