A Four-Storied Nest. 



At a meeting of tlie London Ornithological 

 Section of the Entomological Society of Ontario, 

 Mr. J. Osborn exhibited a four-storied nest of 

 tlie Yellow Warbler (Dendroica «sUva), which 

 he had recently taken near London. In the 

 lower story a Cowbird's egg had been laid, 

 then the second story was put on and another 

 Cowbird's egg laid, a third story added and a 

 third Cowbird's egg laid in it, and in the 

 fourth story were two eggs of the Warbler 

 herself. 



Mr. II. Stevenson reported a nest of the 

 same species, seven inches deep outside, which 

 had the appearance of having been built in 

 different seasons, but the nest was unfortun- 

 ately lost on the drive in from the country. 



Other members of the section reported 

 having found nests of the Yellow Warbler 

 with a single Cowbird's egg partly buried in 

 the floor of the nest so that it would not hatch. 

 In one instance the young were hatched and 

 the Cowbird's egg rotten when found.

after laj'ing two eggs another egg of the 

 Cowbird wa.s left in her care. Still being 

 determined not to be the foster mother to 

 these strangers, she added another story 

 to her already large nest. After laying 

 three eggs her nest was again visited by 

 the Cowbird and two eggs left there. Her 

 little heart failed her this time and she 

 submitted to what seemed to her to be in- 

 evitable and commenced incubation. I 

 had not the heart to take her nest at this 

 time. In due course the young were 

 hatched and to my surprise the Cowbirds 

 were the first to see light, and they formed 

 quite a nest full of themselves. But wlien 

 the young warblers were hatched, I un- 

 ceremoniously tumbled the Cowbirds out. 

 The old birds did not seem much pleased 

 with my actions. Still as" I from a child 

 always took the part of the weak side I 

 felt as if I had done my duty. When the 

 young had flown I seciired the nest to- 

 gether with the eggs in the two lower 

 stories of this cj^ueer house, and it is now 

 in my possession. These eggs were still as 

 fresh as if just laid. A friend of mine took 

 a nest of the same bird in Worcester, 

 Mass., in 1872, of two stories. — Chas. T.

Large Set of Eggs of the Yellow 

 Warbler. 



BY T. W. GLOVEK, WHrfMAN, MASS. 



Thinking that the nesting of a Yellow War- 

 bler {Dendroeca cvstiva) the set of which con- 

 tained six eg'gs of that bird and one of the Cow 

 Bunting may be of some interest to the readoi'S 

 of the O. & O. I submit the following : 



On May 16th, 1888, while searching for birds 

 in a small bit of swamp on the shore of a pond, 

 I found the uest of a Yellow Warbler about 

 one half done, the bird being busy at work. 

 On the 19th I visited the nest again, and found 

 it completed and it contained an egg of the 

 Cow Bunting. Thinking that the Warbler, 

 mio-ht build a new bottom to the nest, leaving 

 the" Cowbird's egg below, I went again on the 

 20th and found an egg of the Warbler with the |, 

 Buntin-'s egg. On the 21st the nest contained 

 fw e?gs of the warbler. I next visited the 

 nest on the 25th and found it contained five 

 . i o the warbler, and on the 26th I found 

 Ihe^iest to contain six eggs of the Warbler and 

 I the old bird sitting. 



I then took them. The coloring is substantial- 

 I lythe same in the six eggs, and as six days 

 vvere consumed in depositing the six eggs I 

 think there can be no doubt about their belong- 

 ing to the same bird. 



The lower part of the nest was composed of 

 cotton waste, probably from some ot 0,^ Uc- 

 lories nea.' by- The remainder was of glasses 

 121 pll nt down. It was about six feet from 

 the ground. XIH. Sept. 1888 p.l^^ 



Brief Notes. 



One day in early June, 1891, while I was 

 searching a small swamp near here, I dis- 

 covered a uest of the Summer Warbler. Ihc 

 nest was situated in a fork formed by four 

 upri"-ht twigs. After watching a few moments 

 I noticed the constructors of this little gem 

 busily engaged in putting on the hnishing 

 touches. -, . , e r. A 



Three days later I returned in hopes of Imd- 

 ing the eggs but I saw neither the egg's nor 

 the birds: I went away disappointed but 

 returned a week later, hoping that tlie eggs 

 had been laid. Judge of my surprise then to 

 see a Rod- winged Blackbird's nest bnilt in the 

 same fork. The nest which contained three 

 eo-gs was built directly over the Warbler's little 

 house ; the side of one being interwoven with 

 that of the other. 



Undoubtedly the IMackbird, with .superior 

 size and strength, h.i-d driven the occupants ot 

 this little summer home aWay, selhshly appro- 

 priating this favored site to thomscl vos. _
