Family PHALAROPODIDJE. 

 Genus Steganopus Vkill. 



206. S. wilsoni Sab. Wilson's Piialauopk. Very common sum- 

 mer resident in this vicinity. Found in abundance about damp prai- 

 ries and on grassy nnirshes. Arrives about the middle of May and 

 remains until into August. I have found its nest from the 2r>th of 

 May to June 25th. The young usually appear about the middle of 

 June and commence to fly the first of July. The breeding plumage 

 of the female of this species is much brigliter and richer than that of 

 the male, as has been recently announced by Rh". A. L. Kundein 

 ("Field and Forest," July, 1876). The male builds the nest and 

 attenils exclusively to the duties of incubation, it alone possessing 

 the naked abdomen during the breeding season. The female always 

 remains near and shows great solicitude upon the nest being ap- 

 proached. The first plumage of the young, described by Dr. Cones 

 on page 4G7, "Birds of the North-west," is retained until Ihcy depart 

 for the south the last of July or early in August. The adults assume 

 the winter plumage during July. Tiiis plumage is much like the 

 breeding plumage of the male except that there is a hoary east over 

 the back and neck caused by grayish tips to the leathers, and the 

 female has a greater amount of dull chestnut on tiie siiles of the neck. 

 The following description of the breeding plumage of the male is from 

 a series of six specimens taken in Northern Illinois the last of May 

 and first of June, 187(3. Bill, legs, and feet i)ure black. Crown of 

 head varying from a light to a dark blackish brown, 'i'he while stripe 

 so evidi'Ut on the nape of the leujale is entirely absent on young males 

 of the preceding year, and but obsoletely indicated in old speci-
