Fascinating Facts
The Gravity-Defying Climber: Unlike woodpeckers, nuthatches can move in every direction on tree bark, including upside down. This helps them find insects hidden under loose bark.
The Tree Detective: Their sharp bills uncover beetles, caterpillars, spiders, and insect eggs from cracks in bark.
The Tiny Tree Pantry: Nuthatches store extra seeds and nuts in bark crevices and cover them with bits of bark or plant material.
