Identification: For female and first-winter/sub-adult birds, bright rufous-chestnut upperparts and tail, head, throat and breast slaty-grey, crown black and crested. Between the two subspecies, grey hind-collar prominent in indochinensis versus usually incomplete in affinis. The tail of adult males can extend up to 27 cm or more but is rarely seen in Singapore. Adult males of three paradise flycatcher species found in Singapore (Amur, Blyth's and Indian) occur as a white as well as a brown morph. However, white birds (rare in Singapore) with nearly all white plumage and glossy black head cannot be conclusively identified as either Amur or Blyth's Paradise Flycatcher.
