192 NOTES ON CALJFOKXIA ANIMALS. 



vidiial at the mouth of the McCloud Kivor on May H'k and si ta.unU'rs 

 were observed on the Sacramento Kivernear iJed lUnd at va."ii»ns times 

 in winter. 



Larus delawareusis Onl. ItiiKj-hUUd Gull. 



A solitary specimen of this Gull waLS taken at Summit Lake, near 

 Mount Lassen on June 5. 



Larus brachyriiynchus Kicli. >s]iorl-bilk'il Gull. 



Kather common at Humboldt Bay, where specimens were shot in 

 December. 



Larus Philadelphia (Ord). Bonaporlcs Gull. 



This bird was seen in the collection of Mr. Fiebij;', who rei)orts it 

 common on Humboldt Bay in winter. 



Sterna forsteii Nutfc. Fornter's Tern. 



Found in comparative abundance at Eaj^le Lake, where it was prob- 

 ably breeding' on Pelican Island. I saw straj' companies of Terns ocea- 

 sionall}' along the river at the northern end of the Sacramento Valley 

 in the spring-, and they were plentiful at Humboldt Bay in the fall. 



Hydrochelidon nigra suriuaniensis (Ginol.;. Black Tern. 



Very common at Eagle Lake, and doubtless breeds regularly there 

 among the tangle and debris of the tule marshes with the grebes, whose 

 deserted nests it has been known to utilize. It was not observed else- 

 where. 



Family PHALACROCORACID.E. Cormoraxts. 



Phalacrocorax dilophus albociliatiis Ridjxw. Farullone Cormorant. 



This Cormorant appears to be present during the greater part of the 

 year on the larger streams of this region, but was wanting on McCloud 

 River in summer, having doubtless repaired to the coast or to suitable 

 lakes to breed. On June 28, I found a large colony breeding upon a 

 small rocky islet in Eagle Lake, their nests being made of reeds and 

 rushes, which they must have carried from the shore a mile away. On 

 March 3 I visited a roostiug-place of this species near the mouth of 

 Pitt Eivcr, to which a hundred or more birds resorted nightly. The 

 trees there were conspicuously marked with their excrement. The 

 largest roost, however, was found on Lower Mad Kiver, near Hum- 

 boldt Bay, every tree along the bank for several hundred yards being 

 crowded with Cormorants towards nightfall. They occupied even the 

 tops of the tallest pines, and the place was a Babel from their commo- 

 tion, although a railroad upon the opjiosite bank of the river was less 

 than a hundred yards from their roost. 



Family PELECANID,^. Pehcaxs. ' 



Pelecauus erythrorhynchos, (Jmel. American While I'eUcan. 



This Pelican was found only at Eagle Lake, where it rcsoits to breed! 

 in great numbers in sunimer. Tliere are two islands lying in this btuiuJ
