_Eggs._--The Wilson phalarope almost invariably lays four eggs, rarely only three. The shapes vary from ovate pyriform to ovate and there is a slight gloss. The ground colors vary from "cartridge buff" to "cream buff," rarely "chamois." The ground color is generally well concealed by numerous markings, more or less evenly distributed. Some eggs are uniformly covered with small spots and dots, but more often these are mixed with a few larger, irregular blotches. An occasional handsome set is boldly and very heavily blotched, sometimes almost concealing the ground color. The markings are usually in very dark, brownish black or blackish brown. In some handsome sets these dark markings are mixed with "bay" and "auburn" markings. The measurements of 57 eggs average 33 by 23.4 millimeters; the eggs showing the four extremes measure =36.2= by 23.7, 33 by =25.1=, =30= by 22.5 and 30.5 by =22= millimeters. _Young._--The period of incubation does not seem to be known. I can find no evidence that the female ever takes any part in it, but that she does not lose interest in her family is plainly shown by her demonstrations of anxiety when the nest is approached; probably she feels responsible for the faithful performance of his duties by her demure spouse. The male broods over the newly hatched young, protecting them from rain, or excessive heat or cold. But they are soon able to run about in a lively manner and care for themselves. Doctor Nelson (1877) writes that "the young have a fine, wiry peep, inaudible beyond a few feet." I believe that the young remain in the grassy meadows, where they can hide in safety, and do not take to the water until they are fully fledged. _Plumages._--In its natal down the young Wilson phalarope is entirely unlike the other phalaropes and quite different from any other young wader. The slender bill and long slender legs and feet are characteristic. It is prettily and distinctively colored also. The prevailing color of the upper parts and of a band across the chest is "ochraceous buff," deepening on the crown, wings, and mantle almost to "ochraceous orange," and paling to buffy or grayish white on the belly and to pure white on the chin and throat. There is a narrow, median, black line on the crown extending nearly or quite to the bill; this is continued in a broad, more or less broken, black stripe down the center of the back to a large black patch on the rump; a black spot on each side of the crown, one on the occiput and several more on wings, thighs, and sides of the back, sometimes run together to form stripes.
