Like many species considered to be cliaracteristically eastern, the Cat- 

 bird is likewise one of the most abundant summer residents of the Wahsatch 

 region. Indeed, we found it not uncommon on the large islands in the Great 

 Salt Lake, specimens being shot in an orchard on Antelope Island in the 

 month of June, while another was obtained, during- the same month, on 

 Stansbury Island, where few other birds were found. Among the mountains 

 it was more abundant, its favorite haunts being the shady thickets along 

 the streams which descend the canons or course across the meadow-like 

 "parks." It was thus an associate of the Olive-backed Thrash and the 

 Redstart (SetopJiaga riiticiUa), but while it did not ascend to as higli an alti- 

 tude as the former, we found the latter with it only in the lower portions of 

 its range. No differences from the eastern birds of the same species were 

 detected, in either manners or notes.
