PINE-GROSBEAK. 43 
expressed on paper. The song is very melodious, not very loud or long, 
but flute-like. When I first heard it I took it for the song of some rare 
Siberian Thrush, and was quite disappointed when I shot the bird to find 
it only a Pine-Grosbeak. The flight is undulating and powerful. We 
found several nests which could only have belonged to birds of this species ; 
but our search for eggs was unsuccessful. The breeding-season is said to 
be the end of May or beginning of June. The nests are generally placed 
in a spruce-fir tree ten or twelve feet from the ground on a thick branch 
close to the main stem. The nest is made on the same model as that of 
the Hawfinch and Bullfinch, but of coarser materials. The outside is a 
framework of slender fir-twigs ; and the inside, which projects above the 
outside, is composed of roots, fine grass, and a lichen which grows on the 
branches of the trees, and might easily be mistaken for hair. The first 
clearly identified eggs of the Pine-Grosbeak which came to this country 
were those obtained by John Wolley near Muonioniska in 1855, and seven 
years later Wheelwright found five nests near Quickiock. The number of 
eggs varies from three to four; they measure from 1:07 to °97 inch in 
length and from ‘74 to °7 in breadth. They may be described as large 
handsome Bullfinch’s eggs. The ground-colour is pale greenish blue, 
boldly spotted, principally at the larger end, with surface-spots varying 
from rich brown to almost black, and with underlying spots of greyer 
brown. Some eggs are also profusely speckled with very small spots, and 
occasionally a Chaffinch-like streak is seen on the large end. On some 
eggs the spots are so large and numerous as to be more or less confluent. 
In winter the Pine-Grosbeak is much easier of approach than it is in 
summer, and it is said that it may even be caught by a snare fastened 
to the end of arod. It feeds upon the buds of various forest trees, the 
seeds of pine and fir cones, and the berries of various shrubs, especially 
those of the southernwood. 
The adult male Pine-Grosbeak is a very handsome bird; the general 
colour of the plumage is dull slate-grey, darker and browner on the wings 
and tail, and paler on the under tail-coverts. The wing-coverts, innermost 
secondaries, and upper tail-coverts have broad white margins, and every 
feather, except those of the belly and under tail-coverts, is fringed with 
rose-red. Bill dark brown; legs, feet, and claws nearly black; irides 
hazel. The rose-red is very brilliant after the autumn moult, but fades 
during winter to some extent. In spring the colour appears to intensify, 
although there is no change of feather. 
The changes of plumage of this species have been the subject of much 
needless controversy. A series of skins of these birds shot during the 
breeding-season is easily divided into three groups. Most of the feathers 
are grey, those of the adult males fringed with rose-red, and those of the 
adult females with golden yellow. Immature females scarcely differ from
