BIRDS OF THE CHILLIWACK DISTRICT, B. C. 
BY MAJOR ALLAN BROOKS. 
Tuts list should have been published many years ago. In 
presenting it at this late date the writer is influenced largely by 
the discrepancies of ranges given in the A. O. U. Check-List of 
1910. 
The compilers of this list were evidently under the delusion that 
Chilliwack was in southeastern British Columbia instead of extreme 
southwestern, west of all the mountain ranges, with nothing but 
fifty miles of level country between its western boundary (Sumas 
Lake) and the sea. 
The area covered by the present list includes the Chilliwack and 
Sumas valleys, a wide alluvial flat, originally mostly forest country, 
on the south bank of the Fraser River, a district about thirty miles 
by eight at its widest part. 
The Fraser River here bursts through the wall of the Cascade 
Range, forming a precipitous cafion about one hundred miles in 
length, running nearly north and south. However improbable 
it may appear this cafon must represent the route to the valley of 
many of its summer residents, which must return towards the 
south through its gloomy length after passing up the east side of 
the Cascade Range on their northward migration. 
Also included in the list are the birds of the Cascade summits 
to the east of the valley, including the valley of the Chilliwack (or 
Chilliweyuk) River and Chilltweyuk Lake, the former a mountain 
torrent rising in the latter and flowing through a deep cleft in the 
Cascades for the greater portion of its course. 
The town of Chilliwack is some seventy feet above sea level, 
the Fraser River being influenced by high tides as far up as Sumas, 
some eight miles down stream. 
The valley is extremely flat and at one time mostly heavy forest 
of Douglas fir, cedar, and hemlock with a sprinkling of large leaf 
maple and heavy underbrush. The banks of the rivers sustain a 
heavy growth of cottonwood, alder and willow. Much of the 
primeval forest has suffered by fire and only the blackened shells
