90 The Ottawa Naturalist [September 



The fox sparrows, white-throats and song sparrows kept 

 up a regular chorus. I had never heard fox sparrows in full song 

 before. Their song is a clear, rich, very sweet warble, usually 

 delivered from a branch some 20 or more feet from the ground. 

 For the first three days of May fox sparrows were abundant, 

 and T saw the last on May 7th. From the large numbers seen 

 it is evident that the Bruce Peninsula is a migration highway 

 for this species. 



The weather remained cold up until May 13th, and the 

 birds dropped in very slowly as follows: 



May .2nd: Barn swallow, kingfisher and winter wren. 

 May 3rd: Towhee and myrtle warbler. May 7th: Brown 

 thrasher, yellow-bellied sapsucker, chipping sparrow and Sa- 

 vanna sparrow. May 9th: Tree swallow, pine warbler and palm 

 warbler. May 10th: Black-throated green warbler. May 11th: 

 Black- and- white warbler and ruby-crowned kinglet. None of 

 the warblers were seen in any numbers and the myrtles were 

 observed only in small flocks of three or four or as single birds 

 and were usually flying over. 



On Ma}^ 13th it w^as evident that an immense bird-wave 

 had come in during the night. Birds were everywhere and the 

 bush below the village was full of them. They appeared to 

 pitch into this bush during the night, travel up the bush and 

 a fringe of cedars as far as the village and then back again until, 

 about noon, they reached a stream about the middle of the 

 bush. Here they drank and caught the insects which were 

 apparently more abundant here than elsewhere. The new 

 species which came in with this wave were the Nashville 

 warbler, yellow warbler. Magnolia warbler, Blackburnian 

 warbler, chestnut-sided warbler, ovenbird, Baltimore oriole 

 and red-breasted nuthatch. With these were a host of myrtle, 

 black-throated green and black-and-white warblers. 



That night another large wave came in and next day I 

 saw the woodcock, greater yellow-legs, lesser yellow-legs, white- 

 crowned sparrow, kingbird, least flycatcher, bobolink, house 

 wren, red-headed woodpecker, water-thrush, Wilson's thrush, 

 catbird, crested flycatcher American pipit, blue-headed vireo, 

 and ruby-throated humming bird. All these species which came 

 in on these two waves were from one to three weeks late. 



;,f-'On May 15th, I saw the wood thrush, redstart, chimney 

 swift and solitary sandpiper and on the 16th the Parula warbler, 

 ,XCape May warbler, black-throated blue warbler and the Can- 

 adian warbler. 



On May 17th the scarlet tanager, and bay-breasted warbler 

 came in, on the 18th, the grey-cheeked thrush, on the 23rd, the
