Food consumption and retention time in captive whooping cranes (Grus americana)
Abstract 10.1002/(SICI)1098-2361(1997)16:63.3.CO;2-J Food consumption, digesta retention time, and food preference were measured for captive whooping cranes fed pelleted diets.

Hand-rearing, growth, and development of common loon (Gavia immer) chicks

Here we report on hatching and rearing methods used to successfully raise chicks to 105 days of age. We experienced a 91.5% hatch rate, and 89.6% of loon […]
