Mountains, in the vicinity of Pasadena. To the eastward, in the 

 eaiions above Claremont and Pomona, it is far outnumbered by 

 sinuosa, and this appears to be the case in the San Bernardino Moun- 

 tains also. There are only a few specimens at hand from that range, 

 and there are no examples of insularis among them. 



September 23, at Echo, Eldorado County, and September 25, at 

 Hume, Fresno County, form early dates of arrival in the Sierra 

 Nevada. There is one specimen at hand from Lakeport, Lake County, 

 taken as early as September 7. In southern California dates of capture 

 lie between October 19 and February 25, though it can hardly be 

 doubted that the birds arrive there earlier and depart later than is 

 indicated by these dates. Farther north there are specimens secured 

 at Stony Ford, Colusa County, March 5, at Oakland, Alameda County, 

 March 14, and at Stockton, San Joaquin County, April 8. 



Following are dates and places of capture between California and 

 Alaska : Fort Klamath, Oregon, April 13 ; Westminster Junction, 

 British Columbia, April 27 ; New Westminster, British Columbia, 

 March 22 ; Parksville, Vancouver Island, April 26 ; Howkan, Alaska, 

 April 25 ; Kuiu Island, Alaska, April 30. These data indicate about 

 the time of the northward migration, but the specimens of insularis 

 thus represented form so small a percentage of the fox sparrows taken 

 in the region that to my mind they should be considered as little more 

 than strays from the regular line of travel. They will serve, perhaps, 

 to indicate dates of passage, but to all appearances the mode of travel 

 is mostly a long, direct flight, rather than a more leisurely series of 

 short flights with frequent stops. 



One specimen from Clackamas County, Oregon, February 16, 

 possibly indicates the occasional wintering of insularis as far north 

 as this. 



It is rather singular that among the non-typical winter birds, 

 referred perforce to insularis, the form they most nearly resemble, 

 there should be so many apparently leaning toward iliacxt. It is a 

 question whether there can be actual intergradation between the two 

 subspecies, with the ranges of unalaschcensis or sinuosa interposed 

 between them, and with insularis restricted to an island habitat. The 

 variants referred to usually resemble insularis in size of bill and 

 bright, ruddy coloration, but show more or less obscure mottling or 

 streaking upon the back, more or less distinct wing bars, and rather 

 sharply defined breast markings. They may really be intergrades 

 between unalaschcensis and iliaca, owing their bright coloring, and
