Vöötselg-väikerähn on "ehitatud" puutüvedel ronimiseks - sabasuled on tugevad ning jalgadel on 2 varvast eespool ja 2 tagapool.
Cardinal Woodpecker is "built" for climbing on the trees - it has stiff tail to provide support against tree trunks and two toes facing forward and two toes facing back.
Sahara aluses Aafrikas on ta levinud, kuid üsna peiduline. Pesaaugu toksib puuõõnsusse ja toiduks kasutab putukaid nagu rähnid ikka. Hlane Kuninglik Rahvuspark, Svaasimaa.
In sub-Saharan Africa this bird is quite common but rather shy. It nests in a tree hole and feed on insects as the woodpeckers usually do. Hlane Royal National Park, Swaziland.
