The Yellow-breasted Chat (Icteria virens) is an insectivorous Neotropical migrant that is essentially restricted to the south Okanagan and Similkameen valleys in British Columbia. It prefers dense riparian thickets, primarily of wild rose, for breeding habitat. Almost all known territories are located along the Okanagan and Similkameen rivers rather than in side valleys. The British Columbia breeding population is almost certainly less than 50 pairs. Although very little is known about its local breeding biology, it is likely that habitat availability is the main constraint to the increase of local populations. About 10 chat breeding territories in British Columbia are on land which has some degree of protection.
