ANNOTATED LIST OF THE BIRDS 67 



PARASITIC JAEGER (Stercorarius parasiticus) 

 Much the commonest species, and the one which most 

 often approaches the coast. Adults of this species and the 

 Long-tailed Jaeger are easily separated by the much longer 

 central pair of tail feathers of the latter, but immature birds 

 are exceedingly difficult to distinguish, and it is possible only 

 under the most favorable circumstances of proximity. The 

 Long-tailed is smaller, with the shafts of most of the primaries 

 white, changing gradually to brownish. The axillars of the 

 Long-tailed Jaeger are usually blacker and more narrowly 

 barred with white. 



Long Island. Regular and fairly common fall transient, 

 chiefly off-shore, July 25, 1914 (Roy Latham) to November 15. 

 Very rare in spring, only three definite records, June 1873 (Law- 

 rence); April 30 (Braislin); June 9, 1917, Orient (Roy Latham). 



ORIENT. Rare transient, more regular in September and 

 October; June 9, 1917; July 25, 1914 to October 30, 1914. 



MASTIC. Jaegers uncommon, the species doubtful; one 

 Parasitic collected. 



LONG BEACH. Rare and irregular fall transient. August 

 14, 1921 (R. Friedmann) to November 8, 1921 (Bicknell and 

 Charles Johnston). 



LONG-TAILED JAEGER (Stercorarius longicaudus) 

 Fortunate indeed are the few who have been privileged 

 to see the adult of this species, with its long tail feathers 

 floating in the breeze, as a migrant off the Atlantic Coast; 

 one of the least known and most graceful of our sea birds. 

 It is apparently even more pelagic than the other species, or 

 else it has a different and unknown migration route. It is 

 more than probable, however, that the immature bird has 

 frequently escaped detection by collectors. 



Long Island. Very rare fall migrant. For years an immature 

 specimen in the Lawrence Collection labelled Long Island was the 

 only record for New York State. On August 26, 1913 Thurston 

 shot an immature bird off Fire Island now in the D wight collection. 

 R. C. Murphy saw an adult with both the other Jaegers off 

 Sandy Hook, September 7, 1918, but was unable to collect it.
