WHITE-FACED HERONS FEEDING

“In January 2013, I had opportunities to witness the feeding behaviour of White-faced Herons (Ardea novaehollandiae, Maori name: Matuku) while exploring South Island, New Zealand. On 9th January, a heron was foraging among a dense mat of aquatic vegetation along a tidal inlet at Picton (above). It would make occasional but accurate strikes at small crustaceans (shrimp and crabs) that would be appropriate for an appetizer.

“On 10th January, a hungry heron was intently investigating the isolated tide pools just off Marahau. It would employ the foot-stirring technique to flush out any fish or shrimp that may be hiding on/in the sand (above). This heron was particularly successful and was able to capture a number of Sand Flounders (Rhombosolea plebeia, Maori name: Patiki) within a short time.

“Brief video clips of its fishing skills may be previewed above and below.

“On 20th January, I was admiring the sunset over the horizon from the coast of Greymouth (above). As darkness descended, I walked across an open grassy field and was surprised to find a few herons still foraging under such low light conditions. They appeared to be picking out small insects, such as crickets and grasshoppers from amongst the short grass (below).”
