ボルチモアムクドリモドキ Icterus galbula

The common oriole in the eastern U.S., wintering to northern South America. Adult males are stunning: bright orange with a black head and bold white wingbar. Females vary from yellowish to bright orange below, often with blotchy black on the head. Breeds in deciduous trees in open woodlands, forest edges, orchards, riversides, parks, and backyards. Listen for rich whistled song. Visits feeders with nectar and fruits. Females can be very difficult to distinguish from Bullock's Oriole, and hybrids do occur. Baltimore is usually brightest on the breast, not the face.
