Sage Thrasher
Oreoscoptes montanus
The sage thrasher is a medium-sized passerine, measuring 20.0-23.0 cm in length and weighing 39.6-50.3g. Its eyes are distinctive ranging from lemon-yellow to amber coloration. Juveniles have paler upperparts and lightly streaked underparts compare to the adults. Adults display brownish-gray upperparts and white underparts marked with dark streaks. Plumage remains relatively similar throughout the year. Sage thrasher can be distinguished from other thrashers by its shorter and less curved bill, shorter tail and smaller size. Voice: Sage thrashers sing to attract mates and establish territories. During migration to their breeding grounds, silent individuals travel ahead of occupied territories by others until they reach an unoccupied one, where they begin to sing they are established. Singing is most frequent during territory establishment and pair formation, and stop when nest building starts.
