teenth the weight shpped 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 1 5 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. 



Ictenis bullocki (Swains.) Bonap. 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 (bullocki) 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 galhula. " This may have been 

 one of the birds that I saw and took to be galhula. 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 galhula reaches its western limit 

 and hullocki 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 ChilUwack, 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 few 

 more seen. (Streator.) East of Coast range only; a rare summer 

 resident; breeds at Cache creek. {Fannin.) Rare at Ashcroft and
