Effects of transmitters on reproduction and survival of wild mallards
Article Abstract:
Researchers examined the effects of two different methods of attaching radio transmitters to mallards, as some experts have expressed concern that the use of abdominal implants affects wildfowl behaviour and survival. The researchers compared the use of transmitters attached to the backs of birds against abdominally implanted transmitters. The results indicated that the back-anchored packages may have had a negative impact on reproduction and, at one of the five sites, the females with backpacks had a significantly higher mortality rate than those with abdominal implants.

Survival and philopatry of female dabbling ducks in southcentral Saskatchewan
Article Abstract:
Population dynamics of dabbling ducks in the southcentral Saskatchewan district was studied using mark-resighting method and subsequent evaluations were made on the use of mark-resighting and return rates as survival surrogates. Resighting probabilities were generated for 5 duck species as well as the corresponding survival probabilities. Evaluation of mark-resighting and return rates showed mark-resighting results can be supported by band recovery method in computing survival rates.

Wetland selection by mallard broods in Canada's Prairie-Parklands
Article Abstract:
A study is conducted to quantify the habitat selection by mallard broods in the Canadian Prairie-Parklands to select the best model of habitat selection in relation to wetlands characteristics. Various predictors of wetland selection including wetland permanence, cover type, moisture level, and vegetation are discussed.
