Short-toed Treecreeper

Certhia brachydactyla

The short-toed treecreeper 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.

Movement and weather

Each season it is first heard regularly where daytime highs are around 9°C (typically 5 to 10°C, from 6 areas). That holds across 20° of latitude, which suggests its timing follows temperature more than the calendar.

Arrival dates

The week it was first heard regularly in each region, after at least six weeks away. Dates differ from south to north, so a region has a range.
