152 Anthony, The Large-billed Sparrow. [April 



I have mentioned were but a stone's throw distant, and from 

 what I now know of the habits of the species, I would expect to 

 find the nest in just that character of cover rather than in the 

 drift wood where the birds were feeding. 



Tule swamps are found bordering the beach, at the mouths of 

 several of the streams north of San Diego but so far as I know no 

 one has reported on the birds nesting there. 



As Mr. Grinnell has said, "it might not be a sin to speculate 

 somewhat in this regard." Can we not by defining the north, 

 east, and south boundaries beyond which we are reasonably sure 

 the species does not pass, mark the probable summer habitat ? It 

 is true the absence of summer records would reduce this more or 

 less to a matter of individual opinion, and my own opinion, based 

 on more than ten years' observation, is that the Large-billed Spar- 

 row is resident along that part of the coast south of San Pedro to 

 San Ramon, Lower California, and that it merely retires to its nest- 

 ing ground a few miles distant to return in August. An overflow 

 migration carries the species to the islands and as far as Cape St. 

 Lucas, but I very much doubt any being found nesting south of 

 San Ramon, or possibly the valley of the Rosario River about fifty 

 miles south of San Quintin. 



If we accept this as the probable summer habitat it remains to 

 find the nesting ground, and I agree with Mr. Grinnell that it is 

 not in the salt marshes. They have been well explored, and from 

 San Quintin north beldingi is the only member of the genus to be 

 found in these localities after the nesting begins.
