SVLVICULID^E — THE WARBLERS. 247 



not yet heen detected in the West Indies. M. Boucard obtained specimens 

 at riuya. Vicente, in the hot country of t)axaca, Mexico. 



In tlie neighborhood of Calais, Mr. Boardnian informs me that this War- 

 liler is common, and that its habits resemble those of the Blacii-poll Warbler 

 more than tliose of any other of tiie genus. It always nests in buslies or in 

 low trees, and in the vicinity of swamps. 



Among the memoranda furnished to the late Mr. Kennicott by Mr. Eoss 

 is one to the effect that the Chestnut— sided Warl)ler was observed at Lake 

 of tlie Woods, May 29. How connnon it i.s at this point is not stated. 



j\lr. C. S. Paine regards the Chestnut-sided Warbler as one of the sweetest 

 singers that visit A'ermont. He describes it as very confiding and gentle in 

 its habits It is cliielly found inhabiting low buslies, in the neighboriiood 

 of taller trees, and it always liuilds its nest in the fork of a low bush, not more 

 than from tlu'ee to five feet from the ground. He has seen many of their 

 nests, and they have all been in similar situations. They will permit a very 

 near approach without leaving their nests. These are constructed about the 

 last of May. Their song continues until about the last of June. After this 

 they are seldom heard. 



J. Elliot Cabot, E.s(|., had tlie good fortune to be the first of our natural- 

 ists to discovei' in .Tune, 18S9, the nest and eggs of this Warbler. It was 

 fixed on the iKnizontal forked liranch of an oak sapling, in Brookline, Mass. 

 The female remained sitting on her nest until so closely approached as to be 

 distinctly seen. Tiie nest was of strips of red-cedar bark, and well lined 

 witli coarse hair, and was compact, elastic, and shallow. It contained i'our 

 eggs, the ground-C(jlor of which was white, over which were distributed 

 numerous distinct spots of umber-lirown. These wei'e of different sizes, 

 more numerous towards the larger end. 



In regard to their breeding in Penn.sylvania, Mr. Nuttall mentions in the 

 second edition of his work that he met them among the Alleghanies at Far- 

 ranville in full s(jng, and had no doubt that they were nesting there at the 

 time. 



The Chestnut-sided Warl)ler usually constructs its nest in localities a])art 

 from cultivated gi'ound.s, on the edges of low and swampy woods, but in places 

 more or less open. t,)uite a number of their nests liave been met with by Mr. 

 George O. Welch, of Lynn, Mass. Their more common situation lias lieen 

 barberry-bushes. The nests vary from about two and a half to tliree and a 

 half inches in external height, and have a diameter of from three to four 

 inches. The cavity is about two inches deep. They are usually composed 

 externally of loosely intertwined strips of the bark of the smaller vegetables, 

 strengthened by a few stems and bits of dry grasses, and lined with woolly 

 ^•egetable fibres and a few soft hairs of the smaller animals. They are usually 

 \ ery firmly bound to the smaller branches by silky fibres from the cocoons 

 of various insects. These nests were all found in open places, in low, wild 

 uiiivsby localities, but none far from a cultivated neighborhood, and tlie
