228 The Ottawa Naturalist. [Mar. 



13th to June 7th (1907), when they are plentiful on the water- 

 front, Hull; in fall from October 1st to 12th. 



244. Hylocichla guttata pallasi, Hermit Thrush. A common 

 summer resident. One is sure to find it at Blueberry Point, Mer 

 Bleue, Chelsea, and similar localities. Extreme dates of stay are: 

 April 10th to October 19th. 



245. Planesticus migratorius, Robin. This old friend under 

 a new scientific name is an abundant summer resident and is 

 increasing in the city. Almost its only enemy there is the 

 domestic cat, which yearly kills untold thousands of this and 

 other species. Something should be done to limit their numbers 

 in and near the city. The Robin may almost be called a per- 

 manent resident, since dates in every month of the year are not 

 rare. A small flock of about four birds stayed in the city from 

 December 21st to March 4th (see The Ottawa Naturalist, 

 vol. XXII., p. 265). The usual date for their appearance in 

 spring is March 23rd, sometimes a week or more before, some- 

 tirnes one or several days later, according to the season. In fall 

 many linger around throughout October, as if loath to go, but 

 all have usually gone by the end of the month, excepting a few 

 stragglers in November. 



246. Sialia sialis, Bluebird. A common migrant and moder- 

 ately common breeder. Late in summer it often becomes 

 strangely rare, where it was common earlier in summer, and 

 later on becomes common once more. It arrives as early as the 

 Robin, about March 23rd (earliest 12th), and is as loath to go 

 as that species. I have seen some as late as November 19th at 

 High Falls, Quebec, where it had to associate with Snow Buntings 

 (Plectrophenax nivalis) at that time. North and South in close 

 proximity!
