It isnominally protected and the gathering of plovers eggsregulated, but nothing is done to enforce the law. The stockof summer birds is large, but it should be larger. In flightthe broad round wings flap slowly ; the bird moves fast, butwithout the dash of the sharp-v/inged plovers ; Lapwings flyinghigh flicker black and white. They can fly high when migrat-ing ; one airman ran into a flock at 6500 feet. Such flights,at a height above range of vision, detract from the value oftheories founded on visible migration, when the birds are oftenforced to low altitudes by adverse winds or other untowardconditions.
