Probing Night Heron
Black crowned Night Heron
"A heron can use a Probing
technique by quickly and repeatedly moving its bill into and out of the water or
substrate, in a method more typical of ibises. Probing is a non-visual, tactile foraging
technique. A more common behavior is Pecking. The heron merely picks up an item
from the substrate, often repeating the movement. The substrate may be the ground, a
plant, or surface of the water. A specialized method is Scooping used by the Boat Billed
Heron. By Scooping, the individual walks forward with its bill partially submerged,
thrusting forward and Scooping with each step.
Prey are caught in the bill either by Impale Capture or Grasp Capture. Impaling
means the bill tip goes into or through the prey. This occurs mostly on large and wide
prey, and mostly by herons with bills large enough to withstand the stress of impaling
and landing a larger prey item. Grasping is the more common capture method in which
prey are caught in a tweezers grip."
