BLUEBIRD 211 



the Bluebird. A single bird was recorded 

 on October 20, 1901 ; one on October 26, 

 1904; one on October 26, 1907; and on 

 October 24, 1907, a flock of fourteen birds 

 was seen flying over westward. In 1908 

 the autumn visitants were all November 

 birds; eight passed over on November i, 

 and three were seen perching on the Com- 

 mon on November 12. 



The Garden, therefore, scarcely consti- 

 tutes a way-station for this species, as no 

 Bluebird has been known to spend the 

 night therein, or indeed pass an hour within 

 the grounds. They make only fleeting calls 

 and continue on their way ; or in many in- 

 stances alight not at all, but pass over in 

 their migratory passage ; for the Bluebird is 

 one of the few species of small birds which 

 migrate by day.
