September. June seems to be 

 almost exclusively its nesting 

 season. Davie reports it as nest- 

 ing in May and June, but it must 

 nest in May farther south, since 

 none of the notes report it ear- 

 lier than June I2th. The com- 

 piler finds its commonest date of 

 nidification to be about June 



20th. 



The nesting site is higher than 

 that of the Red-eye, or any other 

 reported. "Frequently nests in 

 tops of maples in door yards as 

 high as forty feet;" "usually 

 thirty or forty feet;" "generally 

 higher than that of the Red-eyed 

 Vireo;" "usually placed at a con- 

 siderable height;" "high among 

 trees;" "usually in horizontal 

 crotch at greatest possible dis- 

 tance from crotch of tree." 



All that can be gleaned from 

 the reports about the nest itself, 

 is that it is pensile, cup-shaped 

 and lined with fine grass. The 

 nest in the prairie groves of Buena 

 Vista county is generally com- 

 posed of coarse grass and bark 

 strips, very neat though rather 

 rough on outside, and is lined 

 with down from the seed of the 

 Cottonwood tree. 



Mr. Brown finds that the spe- 

 cies seems to prefer the vicinity 

 of towns in migrations, but of 

 groves and open woods for 



breeding. Mr. Peck notes that 

 it "nests about houses and along 

 the edges of woods." With Mr. 

 Smith it "inhabits the shade trees 

 along the street." Mr. D. L. 

 Savage finds it nesting "near the 

 abode of man." 



Those who are acquainted 

 with the Bronzed Crackle will 

 call to mind how, when one of 

 these is aroused, it will utter its 

 loud and excited cries, soon call- 

 ing around it others who join in 

 throwing imprecations upon the 

 intruder, and follow him from 

 tree to tree. The compiler has 

 often found the nest of gilous by 

 thus disturbing the Crackles, who 

 in turn are scolded by the Vireos, 

 if the domain of the latter is in- 

 truded upon. The note of the 

 Vireo in such cases when it fears 

 the safety of its nest, some- 

 what resembles the cry of a cat. 



Mr. R. M. Anderson found a 

 nest in much the same way, by 

 climbing to a Robin's nest which 

 chanced to be near that of the 

 Creenlet. 



Reports upon the habits of the 

 species are somewhat meager. 

 Mr. Bartsch refers us to the beau- 

 tiful lines appended to the des- 

 cription of the species by Coues. 

 but I fear that these same beau- 

 tiful lines are not accessible un- 

 less one is near a college library,
