The Canadian Field-Naturalist 



i: 



district and I have never, but once, found them 

 elsewhere, and then in Toronto, on April 17th, 

 1916, a male was observed. The bird generally 

 chooses a dead branch on a fairly tall pine 

 tree from which to deliver his song, and I found 

 them generally to sing while feeding. They have 

 two songs; the first and most common consists of 

 six or seven Zee's on an ascending scale, it being 

 often very difficult to locate the singer. The other 

 song, which I have only heard a few times and 

 then always in the evening, is shorter, similar, 

 but not so loud 



On June 19th, 1922, Mr. F. A. E. Starr, who 

 was spending a few days with me, and myself 

 started to find a nest and before our search ended, 

 succeeded in finding four. All were placed in 

 ground juniper, about one foot off the ground, 

 half way up the stem, on the outer branch of the 

 juniper, never in the middle. The nests were 

 neat, cup-shaped structures composed of plant 

 fibre, grasses, pine needles and white bark off 

 birch trees, lined with down a and few hairs. One 

 nest contained two young ready to leave the nest 

 and one young Cowbird, which were destroyed by 

 a red squirrel before I could obtain a photograph. 

 Evidently this bird commences breeding around 

 May 24th. As I have never found a complete 

 nest of eggs I hope to do so in the coming season 



An adult male was taken in breeding plumage 

 and is now in the Collection of Mr. J. H. Fleming

Bees Collecting Hemp Pollen. During the 

 past summer, hive bees were frequently observed 

 gathering pollen from plants of Hemp {Cannabis 

 sativa) growing at the Central Experimental Farm, 

 Ottawa. That this pollen must have a great 

 attraction for them is evidenced by the fact that 

 on one large plant as many as twelve bees were 

 seen at the same time busily employed. 



In Hemp the staminate and pistillate flowers are 

 on separate plants, the pollen is powdery, and the 

 plants are normally pollinated by wind. As the 

 bees did not visit the pistillate plants they pre- 

 formed no useful service in return for the pollen 

 provided by the staminate plants. They were 

 there simply in the capacity of robbers. ^.J.

Birds That Are Little Known in Manitoba. 

 Might I add a few little notes on my friend, Mr. 

 Norman Criddle's, observations under the above 

 caption. At the extreme south end of Range 12, 

 west of the prinicpal meridian, I saw one Burrow- 

 ing Owl on May 6, 1913. The Arkansas Kingbird 

 was first seen by me between Crystal City and 

 Pilot Mound on May 21, 1909. Hamilton M. 



Laing, formerly of Oak Lake, Manitoba, reports 

 in the Winnipeg Free Press in a recent article this 

 year that he observed the bird first in 1907 at 

 Oak Lake. Manitoba. In my 15 years' residence 

 in Pilot Mound, commencing in 1901, I saw the 

 Lark Bunting on June 27, 1910, and June 15, 

 1911, as first appearances for those years when 

 the bird was seen in fair numbers. I saw no nests.

New Mammal Records for Alberta. During 

 June, 1922, I collected a specimen of the Richard- 

 son's shrew (Sorex richardsoni) on the Battle 

 River, Alberta, a short distance south of Camrose. 

 So far as known, this is the most southern record 

 for this species in Alberta. 



In late August. 1922, while on a trip with Mr. 

 J. A. Munro and Mr. F. L. Farley to Battle Lake, 

 Alta., I trapped a single specimen of the northern 

 lemming vole, Synaptomys borealis, in a sphag- 

 num swamp near the north-west end of the lake. 

 This also, so far as known at present, constitutes 

 the most southern record in the province. I 

 submitted this specimen to Washington to have 

 it compared with typical borealis collected by 

 Preble in the far north. I thought perhaps speci- 

 mens from a locality as far west as Battle Lake 

 would begin to show characters of the sub-species 

 dalli, but it is pronounced typical borealis. ^J.

Pine Warbler Taken in Nova Scotia. 

 During some twenty-five years of bird study in 

 the field in Nova Scotia I have not found the 

 Pine Warbler until this year, although I am 

 familiar enough with the species during the breed- 

 ing season in New England. On November 4th. 

 1922, I saw a small Warbler in a birch covert at 

 Gaspereau, near Wolfville, N.S., and noticed that 

 it was neither a Myrtle nor a Yellow Palm. At 

 so late a date this was worthy of note and I 

 decided to take the specimen. It proved to be a 

 Pine Warbler (Dindroica vigorsi). The bird was 

 subsequently mounted and presented to the 

 Provincial Museum at Halifax and constitutes a 

 species new to the splendid collection of Nova 

 Scotia birds there. R. W. Tufts. 



Freshwater Amphipods From Canada and 

 Newfoundland.^ Since my note about this 

 subject, in "The Canadian Field-Naturalist" for 

 May, 1921, p. 99, I have been able to get a num- 

 ber of additional records for three of the half 

 dozen species of freshwater amphipods occurring 

 in Canada. 



In addition to the records for Gammarus 

 limnaeus given on pp. 130-132 of "The Canadian
