32 Brooks, Birds of the Chilliwack District, B. C. ees 
4. Colymbus nigricollis californicus. Earep Gresre.— Only once 
taken. 
5. Podilymbus podiceps. Prep-BinLeED GrEBE.— Rather scarce 
resident. A few remained throughout the severe winter of 1908-09, 
though in one case a bird must have survived underneath the ice of a frozen 
slough for about three weeks. There was probably plenty of air space 
where the water had fallen after the ice had formed. 
6. Gavia immer. Loon.— Fairly common and breeds. 
7. Gavia pacifica. Paciric Loon.— Straggler, only one taken. 
8. Gavia stellata. Rep-rHroatep Loon.— A bird in full summer 
plumage in the shop of Mr. Wm. Hall in 1887, which was killed in the 
vicinity. 
9. Stercorarius longicaudus. LoNnG-TAILED JAEGER.— I shot a fine 
white-breasted adult August 23, 1890, at Sumas Lake, and at other times 
saw several others, nearly always in September. This Jaeger certainly 
migrates overland as I have seen it doing so on several occasions — once 
in the Rocky Mountains. I have not yet seen it on the coast where the 
Parasitic Jaeger iscommon. The contents of the stomach of a young bird 
killed in September consisted mainly of half digested Hmpetrum berries 
indicating a very recent sojourn on the tundras. 
10. Larus glaucescens. GLAUcOUS-WINGED GuLL.— The commcn- 
est gull, ascending the smallest streams at the time of.the salmon run and 
perching freely on tall dead trees. 
11. Larus argentatus. Hrrrinc Guiu.— Much scarcer than the 
last. All the records so far published of Larus occidentalis for British 
Columbia refer to this gull. I had almost come to the conclusion that 
occidentalis had no right to a place on the British Columbian list when I 
came across the skin of a moulting adult in the Geological Survey’s Collec- 
tion at Ottawa, collected by Spreadborough on the south end of Vancouver 
Island. 
12. Larus californicus. Ca.irorniA GuLL. Scarce migrant. 
13. Larus delawarensis. RinGc-BILLED GuLL. Fairly common mi- 
grant. 
14. Larus brachyrhynchus. SuHort-Bintep Gui. — At times 
abundant. 
15. Larus philadelphia. Bonapartr’s Gutt.— Common migrant. 
16. Hydrochelidon nigra surinamensis. Buiack TERN. — Two 
adults seen and one taken June, 1897, and one juvenal seen Sept. 1, 1899, 
all at Sumas Lake. 
17. Pelecanus erythrorhynchos. WuitTe Pexican.— A straggler to 
Sumas Lake, usually seen in June or July at the time of the highest water. 
18. Merganser americanus. AMERICAN MbprGANSER.— Common 
resident. 
19. Merganser serrator. Rrp-BREASTED MERGANSER.— Scarce mi- 
grant in the late autumn and again in May. 
20. Lophodytes cucullatus. Hooprep Mrercanser.— Common resi-
