To extinct animal To future animal =__ General Information of Goose By Samson Ho __= = = =Goose is a beautiful but annoying animal, they are verycommon in Northern America and Canada, their species name is //Branta canade//nsis.In Latin, Branta means largely black plumage. The specific epithet, canadensis,means Canada. Branta canadensis is also known as the Canadian goose. These goosespends its summers in Northern America and Canada and is commonly recognized byits black or dark grey feathers.= = = =__Predators of Goose__= =[|Dogs], [|Racoons]and [|Foxes]= = = =﻿= =Scientific Classification= =Domain - Eukarya= =Kingdom - Animalia= =Phylum - Chordata= =Subphylum - Vertebrata= =Class - Aves= =Order - Anseriformes= =Family - Anatidae= =Genus - //Branta//= =Species - //Branta//= = = =**__Habitat__**= =Goose can be found it manydifferent location; it mainly depends on the time of the year. Goose preferredbreeding habitat is tundra, which means Canadian goose can be found in the northof United States during breeding season. The CanadaGoose lives in a wide variety of habitats including lakes, bays, rivers, andmarshes. They breed around waters and marshes in the spring months. Manydogs, raccoons, foxes, owls and weasels (predators of goose) are around theseareas.= = = =The geese move to warmer climatesareas in the fall from September to November when water temperature begins tofall and freeze. They will arrive to the coast of Northern Mexico and BritishColumbia at late October to January, which they will need strong wings andlight body weight to fly this amount of long distance.= = = = = =**__Canada Goose distribution__**= =Yellow, Canada goose summer= =Blue, Canada goose winter= =Green, Canada goose all year= = = == = = = = =**__StructuralAdaptation 1 (Skeleton)__**= =Goose have a skeleton which is adjusted for flight, it isweightless and powerful which is a essential component for flight. The musclesare located in the center of the body such as the chest, the bases of the wingsand legs. Most of the bones are fused together to have a strong, light frame.The skeleton of Goose makes up only 5% of his body weight! Due to the lack ofdiaphragm in Goose, they have evolved from air sacs around their lungs. Goose breathingsystem is much more effective than mammals. They can use 25% more oxygen eachbreath compared to a mammal. The selection pressure that caused this was thatit makes escaping from predators more faster, easier and able to fly.= = = = = =**__Structural Adaptation2 (Webbed Feet and Wings)__**= =On the ground, the geese move by toddling, a funny type ofwalk with webbed feet. In the water, their feet become very useful. Thesegooses use its feet to paddle through water by providing more space to push.When they are flying, the geese use the V formation. This formation reduceseffort needed on the individuals and gives the group a streamlined shape. Theirfeathers also have many advantage, these feathers allow flight and are muchbetter heat-proofing than mammal’s hair. Feathers are made of keratin, whenthey are fully grown, they are completely dead tissue but they replacedannually. The selection pressure that caused this was that Webbed Feet andwings help them to escape from predators more easily, which means better chanceto survive.= = = =**__BehaviouralAdaptation 1 (Mating)__**= =Geeseprefer to mate on water. Geese only swim when it is only required in thebreeding season. The condition of geese is improved generally and helps to keepthem clean and also helps to keep eggs clean.= =Geeseare very careful in choosing their mates and, once they succeeded mating, they willremain together for life. Geese are sometimes difficult to mate. Sometimes agander will not mate with one or two of the females, which mean fertility and hatchability,will be lowered. The selection pressure that causes this was it increases thechance of successful reproduction.= = = =**__BehaviouralAdaptation 2 (Danger)__**= =When geese senses danger, they will spread their wings andhonk loudly for warning the enemies, they will stomp toward the direction ofsafety, herding the rest of the group in front of them. This is how humans controlducks, with arms outspread like a set of wing. The smaller birds and the geeseall respect that gesture. The selection pressure that caused this was it scaresoff the predator and much better chance to survive.= = = =**__PhysiologicalAdaptation (Stomach)__**= =Geese use small intestine and a stomach to break down foodto gain energy. The proventriculus and the gizzard are the two part of thestomach. The proventriculus begins breaking down the food. In the gizzard, foodis ground up more so that the gastric juices can break down the food moreeasily. In the small intestine of goose, enzymes and bile breakdown fats,proteins and sugars. The nutrients then are absorbed into the blood stream.Gooses stores their food as glycogen, it is synthesized and stored in theirmuscles and liver for later use when it is needed. Gooses have a very highmetabolic rate. The selection pressure that caused this was because it is necessaryduring flight.=
