314 MEMOIRS OF THE NUTTALL ORNITHOLOGICAL CLUB. 



A partially albino Robin was seen in Ipswich on August 9th, 1901. In the 

 collection of the Peabody Academy there are three partially albino specimens 

 and one complete albino. 



318 [763] Ixoreus naevius (Gmel.). 

 Varied Thrush. 



Accidental visitor from the west. 



A specimen, now in the collection of the Boston Society of Natural History, 

 is recorded by Mr. C. J. Maynard as having been taken in Ipswich in December, 

 1864. 1 This is the only record for New England. 



319 [766] Sialia sialis (Linn.). 

 Bluebird. 



Common summer resident ; March 1 to October 23 ; average date of 

 arrival for eight years, March 7. 



Eggs : April 23 to June 5. 



Just outside the County line, in Reading, a pair of Bluebirds built their 

 nest in 1864 in one of the signal balls at the railroad station, and raised two 

 broods of young. The ball was lowered fifty times a day for passing trains, and 

 the birds flew out each time and waited till the ball was raised before returning 

 to their nest. 2
