September 6th is the last date for them. 



BOMBYCILLID^ WAX WINGS. 



190. Bomby cilia garrula, Bohemian Waxwing. A rare, 

 irregular winter visitor from the north. The last stay of this beauti- 

 ful bird at Ottawa took place in the winter of 1908-09, when 

 a flock of 22 took up quarters in the rowan-trees on a much used 

 corner in the city. They remained from December 15th to 

 March 6th. (See The Ottawa Naturalist, vol. XXII, p. 266.) 

 Now and then a solitary one is seen, as in December, 1906, when 

 one came to a small mountain-ash tree on Russell Avenue and 

 sta3^ed there for a week. 



191. Bombycilla cedrorum, Cedar Waxwing. A somewhat 

 irregular, but usually abundant summer resident. Some years 

 they turn up in March, in others in April or May, and in 1907 

 they only were seen in June, but then in great numbers. Un- 

 usual dates are: December 1st, 1906; February 22nd, 1908. 

 As a rule, the last ones disappear about September 12th. 



LANIID^ SHRIKES. 



192. Lanins borealis, Northern Shrike. A moderately com- 

 mon winter resident. They arrive from the north about October 

 30th, frequently taking up residence in the city, where they 

 feast on English Sparrows; the latest date for leaving is -Vpril 

 18th (1884). 



193. Laniiis hidovicianus migrans, Migrant Shrike. This, 

 the local breeding form, is a moderately common summer resi- 

 dent, some years rarer than others. The earliest date on which 

 it has been recorded so far is March 25th (1907), and the latest, 

 October 10th (1905). 



VIREONID^ VIREOS. 



194. Vireosylva olivacea. Red-eyed Vireo. An abundant 

 summer resident, although more often heard than seen. In 

 summer, in almost any deciduous woods, one is hardly ever 

 outside of the reach of its somewhat monotonous, prattling 

 song. Time of stay: May 6th to September 26th. How it is 

 often victimized bv the Cowbird, was noted under that species, 

 which see. 



195. Vireosylva philadelphica, Philadelphia Vireo. A rare 

 migrant and probable breeder. As it is small and elusive it may 

 be commoner than supposed. It seems to be one of our latest 

 migrants. On May 17th, 1905, I saw one at Britannia, and May 

 30th, 1906, in a large warbler wave, four to five near C5'-rville. 

 September 4th, 1884, is the only fall date available. 



196. Vireosylva gilva, Warbling Vireo. A common summer 

 resident, found oftener in the shade trees of the cities than in the 

 woods outside. Like the Red-eyed Vireo, it is a persistent singer, 

 even after all other bird notes have stopped in the heat of
