European Starling or Sturnus Vulgaris

The current ostrich series is in North America. Ostrich generally gets up late in summer and moves to the south in winter. There are many ostrich in the northeastern city. Ostrich is omnivorous bird, edible seed, fruit and small insect. They are harmful to the environment because they concentrate on large groups. It is well known that these birds feed in the same area all the year round. This can cause serious damage to plants and agricultural production.

Everywhere in the northern hemisphere, the dark and cold moon from November to February is the day the European ostrich (Sturnus vulgaris) gathers in a big group called "tweets" every night. Prior to arriving at the sleeping places of the public they chose at night, the birds performed a series of complicated aerial exercises in which the flock repeatedly rotated and the shape and density changed at the time of the upper half of the habitat at dusk. These birds, also known as common ostriches, are native to the UK and Europe, are introduced to humans in most parts of the world, and birds are gradually established. Ostrich is a slash-sized songbird with short tail, pink leg and long yellow note. Their rainbow-colored black feathers have creamy spots at the tip of each feather during the winter (hence their name, "ostrich" and Sturnus, meaning "small stars" both)

After completing their annual moulting, the introduced European ostrich (Sturnus vulgaris) actually experienced an increased circulating testosterone level in the blood. Enhanced plasma testosterone levels are associated with the behavior of many bird songs and territories. In addition, the increase in plasma concentrations of testosterone is associated with many physiological and behavioral changes necessary for reproductive. Sure enough, Ostrich sang in the autumn months and insisted on their hideout! In high latitude areas like Seattle where I live, cold winter weather prevents ostrich breeding, but they breed in the southern part of the United States and are warm in winter. In the introduction of English sparrows (also called sparrows), autumn breeding, that is, passersby has also been found

European ostriches: This bird was brought to North America in the late 1800s when 50 pairs of breeding pairs were released at Central Park in New York. European ostriches have become one of the most prevalent birds in North America and breed throughout the tundra area. It inhabits habitats all year round and successfully beat down many native birds as a nesting place. This led to farmers' problems due to the declining bird diversity of urban residents and excessive damage to crops. (Gaulthier and Aubry, 1996)
