280 Agersborg on Birds of Southeastern Dakota. [July 



57. Centrophanes lapponicus. Lapland Longspur. — A not very 

 common winter visitor; always to be found on the bare fields or, towards 

 spring, near creeks, in company with Horned Larks. 



5S. Centrophanes pictus. Smith's Longspur. — Shot one a few years 

 ago; it was alone in a flock of the following species. 



59. Centrophanes ornatus. Chestnut-collared Longspur. — Passes 

 though here every spring in large numbers, a few remaining to breed. 

 About one hundred and fifty miles north of here they are common all 

 summer. The males arrive in large flocks the last week in April, to be 

 followed tenor twelve days later by the females, going in smaller and more 

 straggling flocks. 



60. Passerculus sandwichensis savanna. Savanna Sparrow. — 

 Common summer resident; breeds mostly on the high table lands. 



61. Pooecetes gramineus. Grass Finch. — Summer resident ; breeds. 



62. Coturniculus passerinus. Yellow-winged Sparrow. — Summer 

 resident; breeds. 



63. Coturniculus lecontei. LeConte's Sparrow. — Abundant for a 

 few days the last of May. Found a nest on the Vermilion prairie, June 

 19, 1883, with five eggs ready to hatch. In coloration and shape they 

 looked like miniature eggs of the Horned Lark. Some of the eggs were on 

 the point of being opened by the chicks when found, and not being hard- 

 hearted enough to rob the bird I left them alone. I am almost sorry now 

 that I did not put them in alcohol. 



64. Melospiza lincolni. Lincoln's Sparrow. — Reported from this 

 locality by Lieut. Warren's expedition. I have never found it. 



65. Melospiza palustris. Swamp Sparrow. — Not very common sum- 

 mer resident; breeds. 



66. Melospiza fasciata. Song Sparrow. — Like the foregoing, this 

 species is not a common summer resident. 



67. Junco hyemalis. Black Snowbird. — Very abundant in spring 

 and fall; none remain here during winter. This bird is said to be a resi- 

 dent of Northeastern Nebraska by Professor Aughey, and it has also been 

 noted from Fort Patten, Dakota, four hundred miles north of here. Why 

 it shuns this locality, which abounds in food the year around, I am unable 

 to guess, unless it is not elevated enough. 



68. Spizella monticola. Tree Sparrow. — Our most abundant winter 

 visitant. Large flocks seen everywhere in willow thickets and sunflower 

 patches. Arrive early in October, and they do not all leave us before May 1. 



69. Spizella domestica. Chipping Sparrow. — Not common ; breeds. 



70. Spizella pallida. Clay-colored Sparrow. — This little bird is 

 abundant in spring and fall, lingering here for nearly three weeks in the 

 spring. Every thicket, copse, and weed-patch is full of them; not only 

 the underbrush along the rivers, but young cottonwood groves and 

 weedy fields far out on the prairie. Expect some day to find this bird 

 breeding here, as it does, according to Professor Aughey's Report, just 

 across the Missouri River, only a short distance away. 



71. Spizella pusilla. Field Sparrow. — Not uncommon in summer; 

 never found it nesting.
