Alteration (influenced by mous, mouse) of Middle English titmose : tit- (probably from Old Norse tittr, titmouse) + mose, titmouse (from Old English māse, titmouse).(American Heritage® Dictionary of the English Language, Fourth Edition)
From Middle English titmose, compound of tit ("small bird") and Old English māse ("titmouse"), from Proto-Germanic *maisōn (compare Dutch mees, German Meise, Old Norse meisingr), from *maisaz (“tiny, puny”) (compare Norwegian meis ("skinny weakling")). The plural is formed in imitation of the otherwise unrelated mouse. (Wiktionary)
