Control predators not on islands for wildfowl
A controlled study on two wetland sites in south Manitoba, Canada, in June 1966 (Lynch 1972) found that a higher proportion of artificial nests survived in an area where nests contained strychnine-treated eggs, than in an area with non-poisoned eggs over a 16 day period (84% survival of 215 nests, with predated nests replaced every four days vs. 66% of 225 nests, predated nests replaced every four days). A total of 33 striped skunks Mephitis mephitis and 15 Franklin’s ground squirrels Poliocitellus franklinii were killed.
