Large Seagull Flight

    On Monday Oct. 22, I saw a  very large number of seagulls flying over Red Deer. They seemed to be flying along Piper Creek which is a ravine on the south side of the city. The ravine angles to the southeast.

    I was out walking and just happened to notice seagulls flying by. Then I noticed that there was a continuous line of gulls. They were in a fairly dense formation about 50 m wide. They flew by for 10 minutes without a break. Other gulls seemed to come from the west and join the flight . I would estimate that there were thousands of birds.
  
    The birds wee probably 200 m high and it looked like most of them were young birds . They were too high to identify and I didn't take any field glasses with me. 

    Now were these birds heading south or were they on some local flight? 

   Has anybody else seen a large  line of gulls fly by ?
