24 BIRDS OF THE NEW YORK CITY REGION 



LIST OF IRREGULAR TRANSIENTS (Continued) 

 Migrant Shrike Orange-crowned Warbler 



Philadelphia Vireo *Mockingbird 



Gnatcatcher 

 * Winters occasionally. 

 fSometimes numerous. 



VIII. Casual Visitants. The species in this group 

 occur only at very long intervals, and are all very rare birds 

 in our territory. In some cases their regular migration route 

 or home is not very far away; in other cases they have 

 occurred here and elsewhere in the north-east too often to be 

 regarded as accidental. 



LIST OF CASUAL VISITANTS 



Long-tailed Jaeger Red Phalarope 



Kumlien's Gull Wilson's Phalarope 



Arctic Tern Marbled Godwit 



Black Skimmer Arkansas Kingbird 



Gadwall Lark Sparrow 



Ring-necked Duck Summer Tanager 



Greater Snow Goose Prothonotary Warbler 



Whistling Swan Cerulean Warbler 



Yellow-crowned Night Heron Labrador Chickadee 



IX. Accidental Visitants. The homes of these birds 

 are so far removed from our territory that their occurrence 

 here is probably due in large part to storms, high winds, or 

 a defective migratory instinct. The great majority have been 

 captured in this vicinity once only.
