Trespassing of the Rose-breasted Grosbeak (Zame- 

 lodia ludoviciana) in the Carolinian Fauna 



BY WILLIAM B. EVANS 



This handsome bird, well known ns a breeder in the moun- 

 tainous or more northern part of the Eastern States, is rightly 

 regarded as usuallj' transient in the lower Delaware Valley and 

 in adjacent parts of Pennsylvania and New Jersey. In other 

 words, its journey north in spring is generally continued until 

 the Alleghanian or still higher Canadian zone is reached before 

 it settles to nest. Thus in the " Birds of Eastern Pennsylvania 

 and New Jersey," which embodied the observations and records 

 collected up to the time of its publication in 1894, the Rose- 

 breasted Grosbeak in company with the Chestnut-sided War- 

 bler, Least Flycatcher, Wilson's Thrush, and Savanna Sparrow, 

 is spoken of as never occuring except as a migrant in (he Caro- 

 linian belt (page 6). 



However, within the last few years several instances have 

 come under our notice of the nesting of Rose-breasts south of 

 their accustomed range, in localities well within the character- 

 istic Carolinian Fauna. In addition to those already recorded 

 on page 120 of the above work, the following is a summary of 

 well authenticated cases which are offered without an attempt 

 at explanation. 



In the Auk for 1897, page 323, J. Harris Reed records a 

 nest found at Beverly, Burlington county, N. J., which at 

 that time was the most southern record for New Jersey. 



Early in the 7th mo. of the same year, a nest was discovered 

 by G. H. Moore, at Haddonfield, Camden county, N. J. This 

 was reported to the D. V. O. C. at its meeting held 2d mo. 2, 

 1899, and the nest and eggs became a part of the Club col- 

 lection.
