teenth the weight slipped to one side, and being thrown upon but 
one of the fastenings, broke it. I then procured another nest, an 
old one of the same material, and tried it successively with 15, 20, 
25, 27 pounds, and still it held together; 29 and 30 were reached 
without breakage, but at 31 it began to give, and after a few seconds 
the weight tore through the fabric, without, however, injuring the 
fastenings at the top. On October 19th found an old nest of an 
oriole down by the slough. It was woven of strips of Asclepias 
bark and suspended from four or five twigs. I made a careful test 
of its strength and found that it bore 15 pounds weight without the 
least sign of breaking, but an additional two pounds, thrown care- 
lessly on, tore it from its fastenings. (E. T. Seton.) 
508. Bullock Oriole. 
Icterus bullockt (SWAINS.) BONaApP. 1838. 
The only oriole taken was reported by Dr. Bishop as follows: ‘‘I 
shot a male along the timber near Maple creek, on July 2. This bird 
is typical (bullock?) except that it has the malar region, auriculars 
and sides of head black and many feathers of sides of neck tipped 
with black. Probably a hybrid with galbula.’’ This may have been 
one of the birds that I saw and took to be galbula. Prof. Macoun says: 
‘Breeding in considerable numbers in trees in the valley of the Sas- 
katchewan at Police point, Medicine Hat, Sask., May, 1894; not 
noticed further east.’’ Probably galbula reaches its western limit 
and bullocki its eastern limit somewhere in this vicinity. (A. C. 
Bent.) 
Breeding in considerable numbers in trees in the valley of the 
Saskatchewan at Police point, Medicine Hat, Sask., May, 1894; not 
noticed further east ; common in the trees at Osoyoos lake, B.C., and 
breeding, June, 1905, a large colony was found breeding in the valley 
of the Thompson at Kamloops, B.C., in June, 1889; rather rare at 
Spence Bridge, B.C., in 1889; one specimen seen at Chilliwack, B.C., 
May 23rd, 1901, and several, May 27th, 1906. (Spreadborough.) 
Abundant in some parts of British Columbia. (Lord.) I met with 
this bird only at Ashcroft, where one specimen was taken and a lew 
more seen. (Streator.) East of Coast range only; a rare summer 
resident; breeds at Cache creek. (Fannin.) Rare at Ashcroft and
