       Order Passeriformes    Family Certhidae       Species Certhia brachydactyla
        Short-toed Treecreeper



                                       long, slender, slightly
                       looks slim and  downcurved bill
                       weak in flight



                                                             clean white

                    IN FLIGHT







        FLIGHT: quite direct but weak, undulating, with
        bursts of quick wingbeats.                            saw-tooth pattern
                                                              across wings
          ew species pairs are as difficult as the two
        Ftreecreepers: the Short-toed is best told
        by its calls and song. Even held in the hand,
        the two can be near impossible to separate on
        plumage and measurements alone.The Short-
        toed has more obvious white tips to the wingtip
        feathers and a slightly different pattern across the
        closed wing. In general, the Short-toed is a touch
        duller, a little browner underneath, with a more  plain tail
        contrasted white throat; sometimes it may look a
        little rounder, with its tail angled in more steeply to
        the bark, but such impressions are of little real value.
        It is equally dependent on trees, but does clamber
        on rocks at times.
        VOICE Call quite strong, short, clear tsoit, sometimes longer sreet; song stereotyped,
        with discrete notes (not flowing like Treecreeper’s), stit-stit-steet, stit-it-steroi-tit.  BARK SPECIALIST

        FEEDING Like               below                  Breeds locally in Spain, Italy,
        Treecreeper, creeps about                         France, Low Countries, Italy, and
        branches and tree trunks,                         Balkans. Typically in lowland, often
        probing and picking (but                          deciduous woods, but also in pine
        not chipping away bark)                           forest in hills. Present all year, rare
        for insects and eggs;  TREECREEPER                vagrant outside its breeding range.
