flight reaches the central part of the state in January ; thus Mr. 

 C. F. Goodhue ('85) notes a flock of 20 or more at Webster in 

 January, 1878. By February or March, the birds appear irreg- 

 ularly in the lower portions of the state, though often observers 

 in the central counties do not see them till late May, i. e., dur- 

 ing the second wave. The limits and dates of these peculiar 

 movements will bear a much more thorough working out. 

 The fall migrants have usually left by October. 



197. Lauius borealis Vieill. Northern Shrike. 



A rather common late fall migrant and winter resident 

 throughout the state, occurring as high at least as 2,000 feet 

 in the White Mountains during winter. 



Dates : November 12 to April. 



198. Laiiius liidovicianus I^inn. IvOGGerhead Shrike. 

 A rather rare and local summer resident in the Transition 



valle5^s at least as far north as the White Mountains, and the 

 upper Connecticut valley ; accidental in winter. In view of the 

 general lack of definite published breeding data for this species, 

 it may be well to detail the records for New Hanpshire as far as 

 possible. The bird has been observed at the following locali- 

 ties in the state : Ckarlestown, Mr. W. M. Buswell has observed 

 a pair for at least two seasons in the same yard, and on April 

 26, 1898, took their nest and six eggs. This nest was nearly 

 completed by April 8, and contained two eggs on the 21st. 

 The earliest date at which he has observed the bird in spring 

 is March 20. Concord, near this town a specimen was obtained 

 by Mr. C. F. Goodhue, on January 20, 1879, and identified and 

 recorded by Mr. Ruthven Deane ('79). Hampton Falls, one 

 was observed by Mr. W. E. Cram on August 20, 1899. Hanover, 

 a pair is recorded by Mr. E. B. Frost ('85) to have nested in a 

 fir tree in a person's yard during the season of 1885. The birds 

 were first seen on April 16, and by May 4th, the nest had been 

 built and six eggs laid. Both birds were shot for identification. 

 Mr. Frost, in a letter to the writer, adds that a nest with six 

 young was found at Hanover on May 30, 1884, and that he
