*39. Geothlypis trichas, (Linn.). — Maryland Yellow-throat. 



Two or more of these birds were seen at Marysville January 2, 1878, 

 and occasionally thereafter until about the middle of the month, when 

 their favorite cover was flooded by the Yuba River. It was not seen at 

 Stockton during the following March, nor until April 12, soon after 

 which it became abundant in the thickets near water and in the edges 

 of tule swamps near sloughs. It was also found there in December, 

 1878, but was rare. I have not seen it in the mountains. 



It became rare at Stockton after about November 1, 1878.

*40. Geothlypis mac gillivrayi, (And.). — Macgillir ray's Warbler. 



I have not seen this bird below an altitude of about 3,800 feet. It is 

 rather common at Big Trees in the summer months, but was rare at 

 Soda Springs in September. It is seldom, if ever, found out of low 

 shrubbery in the Sierras.

*41. Icteria virens, ,3. longicauda, Lawr. — Western Yellow-breasted Chat. 



This is a very common summer resident at Stockton, especially in the 

 thickets along the rivers, which it follows into the mountains as high 

 as Murphy's. I first noticed it at Stockton on May 9. It left previ- 

 ous to September 7.

42. Myiodioctes pusillus, t 3. pileolata, (Pall.). — California* Black-capped Green 

 Warbler. 



Arrived at Murphy's xVpril 18, 1877. It was first seen at Stockton 

 May 0, 1878. The last seen during the spring migration was on May 

 27. Between the dates given it had been abundant in the willows along 

 the San Joaquin River. 



At Big Trees it was common from about the middle of May to June 8. 

 1878, while at Soda Springs it was abundant in fall. I did not find it at 

 Big Trees from July 4 to August 1, though after this it was common. 



It is usually found among low bushes in the pine forests, but, like 

 many other birds, frequents deciduous oaks when The leaves are young.
