GULLS AND TERNS: Family Laridae [ 2.79 ] 



River, in September 1909, is the only definite specimen recorded for the 

 State. This bird was badly decomposed when found and it was impossible 

 to tell the sex. We saw one or two birds off Newport, August 30, 1930. 

 In comparison with the larger Pomarine Jaeger, the Parasitic Jaeger is a 

 rapid and graceful flier and more falconlike in appearance. We have not 

 met with it frequently in our offshore trips, but it should be looked for, 

 particularly during April, May, August, and September. 



This jaeger is included by Woodcock (1902.), on A. W. Anthony's 

 statement concerning Parasitic and Long-tailed Jaegers: "I have seen 

 both species off the Oregon coast in winter." As there are no recent 

 records of the Long-tailed Jaeger and we are unable to find any actual 

 specimens from Oregon, we are placing that species in the hypothetical 

 list until such time as we are able to gather more definite information 

 regarding its status.

 Bay, California, and Long Island. In Oregon: Rare winter visitor to coast and 

 Columbia River. 



ON THE BASIS of present records, the Glaucous Gull, or burgomaster, 

 must be listed as an unusual visitor to Oregon. There are three known 

 specimens one (University of Oregon Coll. No. 12.77) taken April 2.8, 

 1915, by Shelton, a second (Jewett Coll. No. 3515) taken on Sauvies 

 Island, December 12., 1914 (Jewett and Gabrielson 192.9), and the third 

 taken by Gabrielson at Tillamook Bay, January 2.8, 1933. In addition, 

 the authors have occasionally seen large pale gulls on the Willamette 

 River in Portland harbor that were probablv this species. One individual
