Subspecies: microstictus x pustulatus? Adult male with all black tail. At first glance this bird looks like one from the northern subspecies, microstictus, which moves a bit southward in winter. Local birds of the subspecies pustulatus have broader black streaks on the back and no reddish tones to the plumage. The yellowish basic color of this bird with a touch of reddish in the head could be a sign of an intergrade between the two subspecies, which is known to happen. |

Subspecies: pustulatus The northern subspecies microstictus is more red on body and head, therefore I say this one is a local pustulatus, but is it male or female? I tend toward male because of the strong colors but females should look alike though a bit paler. Most Streak-backed Orioles I have seen during the winter in Colima have been very red, and therefore supposed to be microstictus visiting. But it doesn't sound very logical that most of the birds around here are migrants when there is a local resident population as well. Have to study this further. |

Subspecies: pustulatus group (West Mexican) ? Adult bird. Likely male with the orange on the head, but not sure how much overlap there is between the sexes. However the strong streaking on the back should indicate a male. But does this type of streaking where the black seems to be broader than the yellow indicate that it is a bird from the Streak-backed group? I'm still not sure. |

2019-06-07 Rancho Primavera (El Tuito - jal), Mexico
Subspecies: pustulatus group (West Mexican) ? Young bird with not black tail. Likely male with the well-marked streaks. About subspecies I'm confused, since both West Mexican and Streak-backed groups (ebird) are present in this part of Mexico. Howell seems to be inconsistent with the definitions and ranges used in ebird, and especially the differences regarding the back streaking makes it less obvious which birds belong to which group. I don't think I've ever seen a really dark-backed bird in this part of Mexico, birds where the streaking seems to switch over and becoming orange-yellow on a black background (Streak-backed trait), why I will have to assume, that this bird belong to the West Mexican group. |
