BULLOCK’S TEOOPIAL, ORIOLE, OR HAKG-NEST. 
43 
inches in diameter. The leaves are ovate at the base, truncato-bilobate at 
the end, with one or two lobes on each side, all the lobes acuminate. It is 
generally distributed, but prefers rich soils. Its bark is smooth on the 
branches, cracked and fissured on the stems. The wood is yellow, hard, but 
easily wrought, and is employed for numerous purposes, particularly in the 
construction of houses, and for charcoal. The Indians often form their 
canoes of it, for which purpose it is well adapted, the trunk being of great 
length and diameter, and the wood light. In different parts of the United 
States, it receives the names of poplar , white ivood, and cane ivood. 
BULLOCK’S TROOPIAL, ORIOLE, OB HANG-NEST. 
Icterus Bullockii, Swains. 
PLATE CCSyiH. — Male, Female, and Young Male. 
According to Mr. Nuttall, who has favoured me with so many observa- 
tions relative to the birds described in this and the preceding volumes, 
“ Bullock’s Oriole occurs in nearly the same localities as the Yellow-headed 
Troopial. About fifty or sixty miles to the north-west of the usual crossing- 
place of that branch of the La Platte called Larimie’s Fork, we observed it 
making a nest quite similar to that of the Baltimore-bird. This species, 
which I have since seen in upper California, where it arrives (around Santa 
Barbara) in the beginning of May, has the same plaintive fifing warble, but 
more brief and less varied. The males also, as usual, arrive in flocks consi- 
derably before the females. They have likewise the same habit of concealing 
themselves for a length of time, carefully gleaning for small larvae, or sipping 
the nectareous juices of the opening blossoms of the trees they delight to 
frequent. On the Platte, the only trees they can resort to are the balsam 
poplars , which border the stream. In all respects this species resembles the 
Common Baltimore-bird, which it supersedes from the first great bifurcation 
of the Platte, to the shores of the Columbia, extending at least as far as the 
borders of Old California. Mr. Bullock, its discoverer, also met witli it 
throughout the table-land of Mexico.” 
Since the above notice was transmitted to me, I have received another
