The short-toed treecreeper (Certhia brachydactyla) is a small passerine bird found in woodlands through much of the warmer regions of Europe and into north Africa. It has a generally more southerly distribution than the other European treecreeper species, the common treecreeper, with which it is easily confused where they both occur. The short-toed treecreeper tends to prefer deciduous trees and lower altitudes than its relative in these overlap areas. Although mainly sedentary, vagrants have occurred outside the breeding range.
The short-toed treecreeper is one of a group of four very similar Holarctic treecreepers, including the closely related North American brown creepers, and has five subspecies differing in appearance and song. Like other treecreepers, the short-toed is inconspicuously plumaged brown above and whitish below, and has a curved bill and stiff tail feathers. It is a resident in woodlands throughout its range, and nests in tree crevices or behind bark flakes, laying about six eggs. This common, unwary, but inconspicuous species feeds mainly on insects which are picked from the tree trunk as the treecreeper ascends with short hops.

Possible
About 20% of wildlife watchers report a Short-toed Treecreeper sighting in Porto on a given day, based on 997 verified sightings from GBIF citizen-science data. It is the 31st most-seen of the 175 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
May and July
In those months about 30% of wildlife watchers report a Short-toed Treecreeper in Porto on a given day, against about 20% in June and August–April, the lowest months. Those are among Porto's driest months, with about 35 mm of rain a month against 140 mm in January.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Short-toed Treecreeper sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
18th of 29
Of the 29 cities where we can rate Short-toed Treecreeper sightings, Porto ranks 18th at about 20%. The best odds are in Turin (Italy, about 50%), Paris (France, about 40%) and Madrid (Spain, about 40%).
Same order: Passeriformes

GBIF citizen-science records
It is estimated from how often the Short-toed Treecreeper is recorded against all the birds logged in Porto (997 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
