Introduction The purpose of this study is to observe the particular animals territorial behavior by examining through various experiments performed on the field. The animal that I chose for the ethology paper is the song sparrows (Melospiza melodia). Song sparrows are found throughout most of North America and in the Midwestern United States. They live in areas of open habitats, edges of wetlands, fields, shrubs, trees, near ponds and they are also found near human habitations. The song sparrows that are found near the human habitats do not sense danger as they are used to humans but if humans go near them, some of them would change their songs/sounds. Human disturbance can have morphological or physiological effects on wildlife
