124 THE WILSON BULLETIN— September, 1921 



Although the dates of an-ival vary widely, the dates of de- 

 parture vary but little. 



In the fall the dates of both arrival and departure are fairly 

 close year after year. 



The Harris Sparrow frequents groves, thickets, and hedges of 

 willow trees, delighting in brushy places with plenty of cover. It 

 spends much of its time scratching on the ground. In the spring 

 it often perches in the trees from ten to fifteen feet above the 

 ground to utter its peculiar song, usually singing in the evening. 

 White-crowned Sparrow (Zoiiotrichia leiicopJirys Icucophrys) . 



A tolerably common migrant frequenting groves and brushy 

 places. My first seen dates cover the period from April 26 to May 

 10. Mrs. E. B. Hayden reported one seen on July 10, 1913. 



Intermediate or Gambel's Sparrow (Zonoirichia Irucupliri/s (jitm- 

 bcli). 

 Noted only once. May 1, 1912. On this day I was watching a 

 sparrow which I took to be a white-crowned sparrow, through the 

 eight-power binoculars at close range, but I soon saw that it was 

 not, as the white crown was not large enough, there was no black 

 line in front of the eye, and the lores were wholly wnite. Its song 

 was similar to the white-throat's song. The bird stayed about the 

 grove all day. 



White-throated Sparrow (Zonotrichia albicoUis). 



This species is the most abundant of all the native sparrows 

 in both spring and fall migrations. It is abundant in every grove 

 and hedge, and even in the tall weeds along the fences. First seen 

 dates in spring are from April 18 to May 3. It has a habit of fre- 

 quenting pine or spruce trees to roost and the first sign of its 

 arrival is usually its sharp call note, frequently repeated just be- 

 fore it goes to roost at dusk. 



Tree Sparrow (Spizclla montlvida )iioiiticuht) . 



An abundant migrant and winter resident. In very severe win- 

 ters of abundant snowfall it is usually scarce or absent during the 

 months of January and February. I have seen it first in the fall 

 from October 24 to November 6. In the spring, last seen dates 

 vary from March 20 to May 6. 

 Chipping Sparrow (Spizclla passcrina p(tss<ri)i(t) . 



This sparrow is a common migrant and a rare breeder. First 

 seen dates are from April 16 to May 11. At two different times 

 in the town of Wall Lake I have seen the young only recently 

 from the nest and still being fed by the parents. 

 Clay-colored Sparrow (Spizella pallida). 



A common but rather inconspicuous migrant. 1 have not noted 

 it in the fall. In the spring it frequents groves and sh rubbery 

 F'irst seen dates are from May 2 to 13.
