沼泽山雀，学名Poecile palustris，又名小仔伯、仔仔红、红子、小豆雀、唧唧鬼子、泥泽山雀。

沼泽山雀虽然名字中有沼泽二字但实际上并不栖息在沼泽中，他们常在针叶林阔叶领或针阔混交林中高大乔木的树冠活动，偶尔也到低矮的灌丛中觅食，在近水源的林区更易见到，这也许就是沼泽二字的来历。

The marsh tit (Poecile palustris) is a passerine bird in the tit family Paridae and genus Poecile, closely related to the willow, Père David's and Songar tits. It is small (around 12 cm long and weighing 12 g) with a black crown and nape, pale cheeks, brown back and greyish-brown wings and tail. Between 8 and 11 subspecies are recognised. This bird's close resemblance to the willow tit can cause identification problems, especially in the United Kingdom where the local subspecies of the two are very similar (there, they were not recognised as separate species until 1897).
