Adaptations to and consequences of an herbivorous diet in grouse and waterfowl

Article Abstract:

Adaptations to and consequences of an herbivorous diet in grouse and waterfowl were studied using a diet selection in the context of their herbivorous diets. It was discovered that both grouse and waterfowl prefer plant foods with higher concentrations of protein. Grouse and waterfowl have slightly different digestive morphology and structure. Meanwhile, the ceca which is a part of their digestive structure, plays an important role in the nitrogen balance for grouse. This explains the reason why they are able to survive in habitats with poor quality food.

Metabolizability and partitioning of energy and protein in green plants by yearling Lesser Snow Geese

Article Abstract:

Estimates of metabolizability of organic matter, gross energy, nitrogen and cell wall parts of pelleted alfalfa by Lesser Snow Geese suggested correlations between body size of these birds and patterns of energy processing. These species and most other herbivorous birds, despite having good rates of energy-retention, seem to lose energy in the form of heat generated while eating.

Reproductive success and survival in relation to experience during the first two years in Canada Geese

Article Abstract:

Research examining the relationships between mating associations and reproductive rates in Canada Geese during their first two years is presented. The benefits of prolonged parental care are emphasized as providing successful breeding.
