Red-tailed Hawks are the most common and widespread hawk in North America. Red-tail numbers have increased significantly as a result of forest fragmentation that creates the mosaic of interspersed wooded and open areas they prefer.
Because sunlight and solar wind always flow outward from our Sun's surface, the tails always point away from our Sun no matter what direction the comet is moving in its orbit. This means that the tails can be in front of the comet as the comet moves away from our Sun on its return to the outer part of its orbit. Two distinct tails develop â the plasma tail and the dust tail. The different shapes and angles of the tails are caused by the way different particles are affected by our Sun. The thinner, longer plasma tail forms a straight line extending from the comet.
