Pond. The nest was not in thick woods but in open pasture near the 

 Canada Road. It was woven of twigs and moss, lined with rabbit's 

 hair and contained four pale-green eggs, flecked with piu^ple and 

 hardly to be distinguished from the moss itself. This nest was in a 

 fir tree about four feet from the ground. It was neatly woven but 

 much less substantial than most nests of that size. Probably the 

 fact that the region is three thousand feet above sea level accounts 

 for a nest in that latitude." 



Henry Nehrling (1896) Myites: "I am in the happy situation to 

 report of the Pine Grosbeak's breeding in northern Wisconsin. Mr. 

 A. J. Schoenebeck found a nest of this bird May 5, 1890, near Boyd's 

 Creek, six miles west of Chaguamegon Bay, Bayfield County, Wis. 

 It was built in a hemlock about nine feet above the ground and seven 

 feet from the trunk. The ground was dry and the forest consisted 

 of deciduous and coniferous trees. The structure was composed of 

 hemlock and other twigs, and the interior of grasses and rootlets, 

 lined with finer grasses and a little moss." 



Eggs. — The pine grosbeak lays from two to five eggs with four 

 being the most frequent number. They are ovate to elongated 

 ovate, and have a slight luster. The ground is "deep bluish glau- 

 cous," "bluish glaucous," "court gray," or "Etain blue"; speckled, 

 spotted, and blotched with shades of "dark grayish olive," "dark 

 olive," "bone brown," "mummy brown," and black, with under- 

 markings which may be in the form either of small spots or blotches 

 of "light mouse gray" or "light neutral gray." Some eggs are uni- 

 formly marked over the entu-e siu-face; others have a decided concen- 

 tration toward the large end where often a wreath is formed. 



The measurements of 40 eggs average 26.0 by 18.3 millimeters; 

 the eggs showing the four extremes measure 28.8 by 18.2, 25.9 by 

 19.S, and 22.4 by 17.0 millimeters. 



Young. — Miss Maddox wrote fm-ther to Knight (1908): "I find 

 that the incubation was completed on May 27, being the thirteenth 

 day after the fourth and last egg of the clutch appeared in the nest. 

 The female bird as far as I could learn did all the sitting. Several 

 times I sm-prised the male bringing her food and saw her leave the 

 nest and receive it from him, near but never on the nest. Both 

 parent birds fed the fledglings after they left the nest, which occurred 

 the twentieth day after they were hatched." 



Plumages. — Dwight (1900) describes the juvenal plumage of the 

 pine grosbeak as follows: "Above, bistre, tinged on crown and rump 

 with dull ochre-yeUow. Wings and tail clove-brown with pale buff 

 edgings sometimes whitish especially on tertiaries and tail. Wing 

 bands indistinct, pale buft\ Below, hair-brown or drab, washed,
