passed it by had I not noticed thie webbed feet. Upon close ex- 

 amination I found it to be a Jaeger, from the hooked bill with 

 separate nail; and called it Parasitic mainly from size of bird, 

 and relative size of the bill compared to that of a Pomarine in my 

 possession. It was doubtless an immature for I could detect no 

 lengthening of the central tail feathers. The plumage was so greased 

 from the decayed flesh, — ^for nothing was left but bones and 

 feathers — that little could be said of original coloration. All 

 looked an oily brownish black. As the bird could not have reachea 

 its condition in much less than ten days' time, its death must have 

 occurred as early as September 10. 



Henslows Sparrow. — At last a record for Lake County! 

 After waiting for many years with open ears, whenever in a likely 

 place to hear it, I was awarded on May 10 (1919), when, in a pour- 

 ing rain I was passing a field often frequented by Grasshopper 

 Sparrows, by hearing a most vehement " sc-licJc se-Uck,'' and sure 

 enough, there on top of some bent-over grass the little fellow sat. 

 I approached as close as I dared, shielding my glass with an um- 

 brella, and took notice of the streaked sides, the characteristic 

 black marks on the head, and particularly of the bill. This last 

 should serve as a good field mark in conjunction with the streaked 

 sides, for it is larger than that of the Grasshopper Sparrow, — - 

 seemingly out of proportion to the size of the bird. Had hopes it 

 would rejnain to breed, but hav-e neither seen nor heard it since. 



Orange-crowned Warbler. — The spring migration, deficient in 

 the numbers of many species, and especially so in regard to the 

 Black- throated Blue (only four individuals having been seen), con- 

 tained, however, a generous sprinkling of this scarce and easily 

 overlooked nondescript Warbler. I had opportunity to study it 

 closely and took advantage of it. Although the first suspects were 

 high in the trees and the identity arrived at mainly by a chance 

 song, a few days later I found a few at two different locations 

 marooned in low growth by stress of chilly and cloudy weather. 

 A particularly pleasant hour was spent with one on May 17 among 

 a mixed company of Warblers in a thorn bush thicket. Chilly and 

 with a fine drizzle of rain, all the other species were diligently 

 and dejectedly feeding without a sound, but the little Orange- 

 crowned kept up a continuous movement, flitting its wings like 

 a Kinglet, and passing from one thorn bush to another, the busiest 

 bird in the lot; and I would have lost him, a number of times had 

 he not kept up a loud and oft repeated " chip, chip, chip," which 

 enabled me to locate him again at once. 



Pine Warbler as a Summer Resident. — On July 16, and also 

 again on the 21st, 1919, I watched for some time a female of this 

 species. The bird was in an old gravel pit grown up to a thicket
