Comparison of foraging of canada goose and brant goose at different locations
The levels of forage quality and macronutrients vary among the turf grass and are classified as one of the major factors influencing the foraging activities of the geese. The rate of feeding in Canada goose is majorly accelerated depending on the nitrogen content, calcium content and the level of crude protein. This feeding is also lowered by the presence of acidic detergents and fiber contents among different turf grasses. INTRODUCTION The Canada goose is the most common species of geese widely distributed in northern America and the only species characterized by Nearctic avifauna. Canada is large parts of the low -arctic regions and the temperate regions, which include the flat, boreal forests, featureless tundra, parkland and prairies: the meadows of high mountains and several varieties managed refuge conditions including habitats of human beings.
Stop watch 2. Tide meter. Several Canada geese species 4. Several Brant geese species The Canada geese and the Brant geese are released in the different locations under investigations and their behavior observed and time is taken in which they remain standing, they sit and feed, fly, time sitting and not feeding, time sleeping, time preening, time they peck while standing, rate of sit pecking and their peak rate which is determined by the number of pecks they make in a minute. The two species of geese are transferred from one location to another and the same procedure repeated in all the locations under investigation. Moreover, the tall grasses had a lower nitrogen concentration compared to the short grass forages in the areas like gateway where the Canada goose species of goose preferred the longer grass, which was approved that no sign of decreased preference on the longest grass in different locations.
Breaking of the lamellae of the grass at different stages of growth can be directly associated with the proportion of the tissues strengthening the grass and this determines their ease of digestion. The presence of apical strains of the grass, which are easy to break and have a higher digestibility in the system, facilitated the elevated foraging at locations of a higher level of the grass. The foraging of geese is directly influenced by the nutritional content of the forage; increased growth of the forage increases its fiber content and decreases the concentration of nitrogen present in the forage. This implies that the tall forages have increased nutritional content but low digestibility and hence only less energy can be obtained from them and this explains the reduced activities like the rate of pecking in geese at the conference hall.
The graph represents the time and rates of the behaviours of the geese when exposed to the various locations with the time they fed while standing being the most common followed by the time they were standing and not feeding ,followed by the time they fed while seated then then the rates of pecking while standing and when sited. The graph above show the foraging of geese at different location with the highest being at miller field followed by mt. Loreto ,great kills ,conference hall and then gateway. The graph above demonstrates various variables based on the geese pecking rate as shown by the data collected at different locations. WORKS CITED 1. R. E. Sinclair.
