When tides are unusually high, there is no beach on which to roost (although the imported boulders are available). Thus the shorebirds seek out ploughed fields or other situations with good views, or even are known to go in under crops and out of the prying eyes of enemies like merlins and peregrines, until their tidal clocks tell them it is time to head back to the Minas Basin or Chignecto Bay shores where the tide is ebbing to allow access to the mud and mud shrimps etc. again. Also, flocks are constantly arriving from the north and other flocks departing toward the south, so that the numbers we see from day to day can fluctuate widely. Check out the Blomidon Nat. Soc. Calendar and peruse the tide heights for August to see the range from nearly 16 m. to about 10 m. during the month. Next month, I think on Sept. 11, I will be leading a BNS field trip on an extremely low, low tide -- check out blomidonnaturalists.ca for the event listings for the club, and you don't have to be a member to participate -- I will be showing worms and mud shrimps and shells and crabs and whatever we can find on the Kingsport mudflat.
