The Swallow-tailed Hummingbird is a beautiful tiny bird with a green and blue body and a long tail. It usually lives in urban and suburban areas and feeds on nectar which is why it has a long beak as well. Sometimes it may catch some insects in flight for additional protein. These little creatures can be pretty aggressive with each other and sometimes even larger birds that are too close to their feeding or nesting area. They are also very peculiar to watch during their mating season that occurs between October and March mostly because of their rapid zigzag dances and their singing (usually right before sunrise).
