啄木鳥與五色鳥都會挖樹幹,不過五色鳥只是鑿洞為巢,並不會在樹幹中找尋食物,但小啄木則以挖鑿樹幹中的螬蠐為主要食物(通常是朽木但也不以朽木為限,育雛也是鑿樹洞進行的),所以又有「樹醫生」的外號,雖然這樣的習性對樹木健康幫助不大,但意思到了……(樹木腐朽的原因主要是真菌感染),小啄木是台灣較常見的啄木鳥,不過通常牠們都高高在上而且忙著啄木忙個不停,很難拍攝。

翅黑有白斑,腹乳白帶髒汅有縱紋,拍攝上對焦一直有些不準焦,不曉得是牠的花紋容易迷惑相機的對焦系統還是其他原因?腳趾特化成前2趾後2趾(與一般鳥類是前3趾後1趾不同),適合在樹幹上攀爬.學名:Dendrocopos canicapillus
