 NESTING OF SOME CANADIAN WARBLERS. 



By Wm. L. Kells, Listowell. 



The Chestnut-sided Warbler. 



On the northern end of Wildwood Farm, which lies on the 

 northwest of the town site of Listowell, there exists a tract of hard- 

 wood timbered forest of about seven acres in extent; but which, 

 with that on the adjoining- farm to the north, covers an area of 

 over twenty acres. Most of this tract has a good natural drainage; 

 but some parts towards the centre are lew, and contain pools of 

 stagnant water until after mid-summmer. The greater part of 

 this wooded tract is still in its primitive wildness; for though the 

 larger timber of the forest of tMrty years ago has been mostly 

 removed, yet the subsequent growth is yearly increasing in size, 

 though none ot the trees are ever likely to attain the proportions 

 of their ancestors of the "backwoods." In most parts of this 

 woodland there is a thick growth of low, young underwood; 

 which, when in full leaf, as it is at the end of May, is very 

 dense, being also intermingled in most places with wild raspberry 

 vines. Amid such scenery the chestnut-sided vi'arbler evidently 

 loves to make its summer haunts and home; for here, from the 

 early days of May till summer time is over, its rather plaintive 

 song-notes are daily heard, and here, for several years past, I have 

 noted the nests of several of the species. On May 22nd of the 

 past year (igoo), not far distant from each other, I noted two 

 newly formed nests of this bird. The first seen was deep in the 

 underwood, and placed in the fork of a small bushy maple about 

 twenty inches off the ground. This was so bulky and compactly 

 built that at first I took it to be a nest of an Indigo Bird. It was 

 formed of a kind of woody fiber gleaned from decayed timber, 

 vines and grasses, and lined with long, black, horse-hair, which it 

 must have taken the builder a good deal of time, with much 

 trouble, to collect and place in position. On the above date this 

 nest contained an egg of the cow-bird, which I removed and — five 

 days after — it contained three eggs of the chestnut-sided warbler, and
