It’s believed the bird first discovered this unusual method by accident. A high-tide had inundated a freshwater pond. The warbler didn’t realise this and drank the water. When it tasted the salt, the bird spat it out and hit a mosquito, which fell on the ground. The warbler picked up the mosquito in its beak, but still tasted some salt. If flew to another pond and dipped its beak in the water before consuming the insect.

The Archer Warbler can fire water for a distance of about ten feet. Depending on the age of the bird, these warblers can normally fire 50 or 60 jets of water per day.
