Water from 10 saline wetlands in Saskatchewan was provided as drinking water for 1-day-old mallards (Anas platyrhynchos). Ducklings given water with conductivity from 3,750 to 7,490 microns hos/cm grew as well as birds on fresh water during a 14-day trial, but birds given water with conductivity of 4,000 microns hos/cm grew poorly during the last 2 wk of a 28-day trial. Ducklings given water with conductivity of 7,720 micron hos/cm grew poorly during a 14-day trial. Six of 10 ducklings given water with conductivity of 20,000 microns hos/cm died, and only two of nine ducklings given water with conductivity of 21,500 microns hos/cm survived 14 days. Survivors were much smaller than controls and had many abnormalities. All ducklings given water with conductivity of 35,000 and 67,000 microns hos/cm died within 60 and 30 hr, respectively. The results indicate that ducklings hatched on many saline wetlands will suffer toxic effects unless they are able to find a source of fresh water shortly after hatching.

Modulatory effects of inorganic mercury (Hg (II)) and lead (Pb (II)) on immune responses of Pekin ducklings (Anas platyrhynchos domesticus) upon a viral-like immune challenge.

Article Synopsis
- Trace metal contamination, especially from mercury (Hg) and lead (Pb), can harm wildlife health, particularly affecting young birds' immune systems.
- This study focused on how these metals influence immune responses in Pekin ducklings following a viral challenge, revealing that Hg (II) increased pro-inflammatory gene expression while Pb (II) resulted in lower natural antibodies and reduced white blood cells.
- Overall, both metals negatively impacted immune competence in ducklings, leading to inflammation and impaired immune function.
Swimmer's itch control: Timely waterfowl brood relocation significantly reduces an avian schistosome population and human cases on recreational lakes.

Swimmer's itch (SI) is a dermatitis in humans caused by cercariae of avian and mammalian schistosomes which emerge from infected snails on a daily basis. Mitigation methods for SI have long been sought with little success. Copper sulfate application to the water to kill the snail hosts is the historically employed method, but is localized, temporary, and harmful to many aquatic species.

Neonatal Anseriformes require specialized care for successful development including access to clean swimming water and food presentation that stimulates natural feeding behavior. Knowledge of natural history is essential for successful rearing. Lightweight and waterproof materials can be used for corrective splinting of many developmental disorders that allow birds to ambulate normally and swim.

A significant health issue, reproductive toxicity is mostly linked to exposure to various environmental heavy metals. A pervasive toxin that occurs naturally in the environment is arsenic (As). This research was done to determine the effects of various doses of inorganic As supplements on the reproductive organs of adult male white Pekin ducks.
