Similar species
Treecreeper, which has a slender down-curved bill and can only climb up trees rather than down.
Ecological significance
Helps control forest insect populations by foraging on tree bark, and provides nesting cavities for secondary cavity nesters.
Conservation status
Least Concern, with a stable population trend
Observation tips
Listen for their loud, ringing calls in mature deciduous or mixed woodlands, or watch backyard bird feeders where they readily take sunflower seeds and suet.
Interesting facts
Nuthatches get their name from their habit of wedging nuts into cracks in tree bark and 'hacking' at them with their strong bills to eat the kernel.
