129. Junco hyemalis hyemalis. Junco. A common winter 

 resident from September 22 to May 7. The periods of greatest 

 abundance were October and early November during the fall mi- 

 gration and March and April in the spring. The great majority 

 passed farther south to spend the winter but large flocks remained 

 about the weed patches along the river. Next to the tree sparrow 

 it was probably the most abundant winter bird. 



130. Melospisa melodia melodia. Song Sparrow. An abun- 

 dant summer resident from March 15 to November 12. No nests 

 of this species were found in the county, and I neglected to record 

 dates on which young birds were seen. 



131. Melospiza lincolni lincolni. Lincoln's Sparrow. A toler- 

 ably common spring migrant from April 7 to 25 and a more abun- 

 dant fall migrant, September 12 to October 18. This species 

 was probably common at times but owing to the difficulty of picking 

 it out among the great flocks of sparrows it often passed undetected. 



132. Melospisa georgiana. Swamp Sparrow. A common mi- 

 grant from April 4 to May 22 and September 12 to October 25. 

 Sometimes appeared in large flocks, but usually it was inferior in 

 numbers to song, field, fox, chipping and white-throated sparrows 

 in the great migration flocks. 



133. Passer ella iliaca iliaca. Fox Sparrow. A common migrant 

 from March 14 to April 15 and September 23 to October ZO. In 

 the spring the fox sparrow was usually abundant for only a few 

 days. In 1913 and 1915 it did not arrive until April 1 and 2 

 respectively, and the last one seen was on April 13 in both seasons. 

 In 1914 a few came on March 14 and small numbers were seen on 

 every trip up to April 7, when they became common. The last 

 one was noted on April 15. 



134. Pipilo erythrophthalmus erythrophthalmus. Chewink. A 

 common summer resident from April 4 to October 14. The chewink 

 was never found in great numbers, but a pair or two were seen 

 on nearly every trip. No nests were found but on the camping 

 trip at Mormons Lake, adults were frequently seen followed by 

 young birds. 



135. Cardinalis cdrdinalis cardinalis. Cardinal. The cardinal 

 was an increasingly common permanent resident. One nest was 

 found May 24, 1913. This nest was built in a hawthorne tree in 

 a dense thicket and contained one cardinal egg and two of the 

 cowbird. Several pairs remained along the river and it was no 

 uncommon thing to see from three to five birds in a day's tramp. 

 A brood of fledglings begging for food was found August 22, 1914.
