210 BIRDS OF THE PUBLIC GARDEN 



flew over. The only instance of a pair tarry- 

 ing, as if it might have intended to nest, 

 was in 1902, when a pair remained in one 

 section of the Common, that which lies 

 nearest to Park Square, from April i to 14, 

 and then disappeared. They were seen 

 daily during those fourteen days. The 

 earliest date of the Bluebird's arrival has 

 been March 14, in 1902. 1 Other dates of 

 arrival have been March 15, 16, 19, 21, 

 and April 4 and 5. Some visitants have ap- 

 peared in May, apparently drawn along in 

 the larger migratory movements. Thus in 

 1902 one was present and in song on May 9, 

 and another on May n. In 1903 one came 

 on May 19. In 1904 two male birds were 

 seen on May 5. In 1905 a female bird ap- 

 peared on May 16, and another came on 

 May 20. In 1906 a male bird was present 

 and singing on May 20. In 1908 a male 

 bird was on the Common on May 10.

 male bluebird on the Common, on Monument Hill, on 

 March 14. A blue jay was also present.
