Artificially incubate and hand-rear wildfowl in captivity
A replicated study in 1964-1965 in two sites in British Columbia, Canada (Crouch & Crouch 1966) found that bufflehead Bucephala albeola eggs can safely be transported and hatched within a portable incubator. In 1964, 11 of 12 eggs transported in the incubator hatched. In 1965, nine of 14 eggs hatched. Egg collections each year were treated similarly (all eggs partially incubated on the nests) and were in transit for 10 hours (across 300 miles) before they were set under bantam hens for final incubation. The temperature varied only 0.3oc and was constant most of the time. The custom-designed incubator consisted of three main elements: the plywood housing, the electrical heating element, and the thermo-switch. A small glass window was installed in the centre of the upper door to observe the eggs and temperature without opening the door.
