Certhia brachydactyla
Short-toed Treecreeper
The Short-toed Treecreeper is a small, brown bird with a slender, curved bill and stiff tail feathers. Its upperparts are mottled brown, providing excellent camouflage against tree bark, while the underparts are predominantly white with a buff tinge.
Both sexes look alike, with no significant seasonal plumage changes. Juveniles closely resemble adults but may have slightly more diffuse markings and a shorter bill.

Short-toed Treecreepers are found throughout much of western and southern Europe, including parts of North Africa and the Middle East. They inhabit deciduous and mixed woodlands, parks, and mature gardens with large trees.
In the UK, they are primarily found in southern and eastern England, with some populations in Wales. Their range has been expanding northward in recent decades, possibly due to climate change.

The Short-toed Treecreeper's diet consists primarily of small invertebrates found on tree bark. They feed on insects, spiders, and their eggs and larvae, which they extract from crevices using their specialised curved bill.
In winter, they may occasionally supplement their diet with small seeds.
Short-toed Treecreepers exhibit a distinctive spiralling movement as they climb up tree trunks, using their stiff tail feathers for support. They forage by probing into bark crevices with their specialised curved bills.
These birds are generally solitary or found in pairs, occasionally joining mixed-species flocks outside the breeding season.
The Short-toed Treecreeper's call is a high-pitched, thin 'tsee-tsee-tsee'. Their song is a series of high, tinkling notes, often described as 'tit-tit-tit-e-tit'.
During territorial disputes, they may produce a rapid, trilling 'srrri-srrri-srrri' sound.
Breeding season for Short-toed Treecreepers typically begins in April. Males establish territories and attract females with their songs and display flights.
Nests are built behind loose bark or in tree crevices, constructed from twigs, bark strips, and moss, lined with feathers and hair. Females lay 5-6 white eggs with reddish-brown spots.
Incubation lasts about 14-15 days, primarily by the female. Both parents feed the nestlings, which fledge after 15-17 days. Pairs often raise two broods per season.
The Short-toed Treecreeper typically lives for 2 to 3 years, with a maximum recorded lifespan of 5.9 years.
Like all birds, lifespan can be affected by factors including predation, habitat quality, disease, and access to food sources.
While the Short-toed Treecreeper is currently listed as Least Concern, it faces localised threats from habitat loss and fragmentation.
Conservation efforts focus on preserving mature woodlands and maintaining a diverse age structure in managed forests to ensure suitable foraging and nesting sites.
