264 LONG-WINGED SWIMMERS — LONGIPENNES. 



on spruce-trees. One nest which he examined contained three young birds of a dirty- 

 yellowish color, thickly spotted with dark brown. He saw between twenty-five and 

 fifty Gulls about that breeding-place, but he found only a few of their nests. These 

 birds were said by the Indians always to breed in similar situations. 



In regard to twenty -two other nests described by JVIr. MacFarlane, we gather that 

 the usual maximum luimber of eggs in a nest is three — very rarely four; that all are 

 placed in elevated situations, on high stumps, or bushes, or trees ; that the nests are 

 made of sticks, and lined with hay and other soft substances ; and that the parents 

 are fearless when they have young, flying about in close proximity, and screaming 

 vehemently. The nests were found with eggs from June 10 to the 10th of July ; 

 and in some cases mosses and lichens from tlie pines and spruces had been largely 

 used in their construction. They were usually placed flat on horizontal branches at 

 some distance from the trunk. The eggs jirocured by Mr. MacFarlane vary in length 

 from 1.90 to 2.05 inches, and in breadth from 1.35 to 1.45. Their ground-color is a 

 grayish olive, passing into a greenish tint ; while the markings consist of small spots 

 of clove-brown, and are chiefly gathered around the larger end of the egg. 



Specimens of this Gull and of its eggs were also procured at Fort Resolution, on 

 the Yukon; at Fort Simpson, at Big Island, at Fort Eae, and at Peel's River Fort; 

 at Fort Good Hope, Fort Anderson, on the Lower Anderson ; and at various other 

 points.
