THE FIRST published Oregon record of the Long-tailed Jay was by Hen- 

 shaw (1880), who recorded a specimen from The Dalles, October 4, 1879, 

 and stated that the species was tolerably common near Portland. Bendire 

 (i895a) noted it in the Fort Klamath and Klamath Falls districts in 1883, 

 and numerous writers have included it in their lists since. Walker (1916) 

 recorded a bird seen at Tillamook, November 19, 1914, the only record 

 for the northern coast counties. This jay has one of the most peculiar 

 distributions of any Oregon bird. It reaches the northernmost limits of 

 its range along the Columbia bottoms near Portland. There is a thriving 

 colony on Sauvies Island from which occasional individuals straggle across 

 to the Washington shore. In the vicinity of Portland and in the northern
