# Nuthatch or treecreeper? Check the bill and the climb

Both birds look for food on bark. Watch how the bird moves, then check the bill and the markings around its eye before you mark it as seen.

If a small bird walks head first down a trunk, look for a dark stripe through its eye and a straight, pointed bill\. Together those clues point to a Eurasian Nuthatch\. If the bird is going up, keep looking: both nuthatches and treecreepers climb\.

## Read the movement, then look at the head

The [RSPB’s Nuthatch account](<https://www.rspb.org.uk/birds-and-wildlife/nuthatch>) describes a compact blue\-grey bird with a bold dark eye stripe\. You may see it change direction on the bark and walk down head first\. Watch for actual steps\. A bird looking down in a still photo might not have been moving down\.

The dark stripe through the eye and the pointed bill are visible even in shade\.

A [Eurasian Treecreeper](<https://www.rspb.org.uk/birds-and-wildlife/treecreeper>) has a finer bill that curves down and a mottled brown back\. The RSPB describes how it often spirals up a trunk and flies down to start another climb\. If the bird disappears behind the trunk, wait for the next side view\. It can show the shape of the bill and the markings around the eye together\.

## What the birds do on the bark

[Adamík and Kornan](<https://ornisfennica.journal.fi/article/view/133608>) watched both species feed in an old\-growth forest in Slovakia over four breeding seasons\. Both used trunks and branches\. Both often picked prey off the surface\. The nuthatches more often probed, which meant pushing the bill into a crevice or through the surface\.

Across the four years, the share of recorded feeding actions that involved probing ranged from about 6% to 25% for nuthatches\. For treecreepers it ranged from 0% to 4%\. Those figures describe one forest in the breeding season\. They explain why a quick glimpse of a bird picking at bark gives you little to go on\.

## When a view is enough to mark it as seen

The dark eye stripe, pointed bill and head\-first descent can help you decide whether to [mark Eurasian Nuthatch as seen](<https://animalchecklist.com/animal/eurasian-nuthatch>)\. A fine curved bill and mottled back may only narrow the choice to a treecreeper\. A [2024 study in an Austrian floodplain forest](<https://link.springer.com/article/10.1007/s10531-024-02852-7>) grouped Eurasian and Short\-toed Treecreepers because the two look so similar\. Leave the species unchecked if you could not see enough to tell them apart\.

BirdLife lists these as separate species: [Sitta europaea](<https://datazone.birdlife.org/species/factsheet/eurasian-nuthatch-sitta-europaea>), [Certhia familiaris](<https://datazone.birdlife.org/species/factsheet/eurasian-treecreeper-certhia-familiaris>) and [Certhia brachydactyla](<https://datazone.birdlife.org/species/factsheet/short-toed-treecreeper-certhia-brachydactyla>)\.
