Hwy. 58, Simmler to McKittrick, Kern Co, Calif : 39, undoubtedly the same flock seen earlier in the day, flying NE. Feb. 18 San Luis NWR, Merced Co, Calif : 400 . Some dancing. Two birds apparently engaged in a courting flight-- One bird gave a more rapid, louder series of flight calls than normal in flight as it joined another lone flying bird. It then flew with its wings arched upwards and stiffened for 30 seconds very close to the other bird. They continued in normal flight, but still very close together, out of sight.
