The collared owlet (Glaucidium brodiei)
Collared owlets transition through various age-dependent colour morphs. A capture-recapture study of collared owlets in Taiwan provided evidence of this. On the first capture, the individual was 56 days old and showed fledgling colour morph stage; having less spots and barring on the back and top of the head and not having a completely formed occipital. On the second recapture, the individual was captured 165 days after hatching and demonstrated a rufous morph; having an overall orange-red colour, barred back, spots on the head and a formed occipital. On the third recapture, the individual was 394 days old and was in its final grey morph
