Delaware River, opposite Tinicum; April 7th, 1902. L. I. Smith.^ 



Wildwood; April 1st, 1904. Wm. L. Baily. 



In addition to the inland record at Pemberton, there was one bird 

 obtained at Marlton, April 4th, 1904, J. D. Carter.^ Mr. Scott took 

 one at Princeton in 1879,* and the species is reported to have occurred 

 rarely in Morris county by Mr. R. C. Casky. 



At Englewood, N. J., Mr. Geo. E. Hix,"^ has recorded the occurrence 

 of a single bird on a pond on June 10th, where it was seen twice after- 

 ward, disappearing between the 24th and 27th. Mr. H. H. Hann 

 records a few shot on the Passaic river, near Summit.^ 



3 Colymbus auritus Linnaeus. 

 Horned Grebe, Hell-Diver. 



I'LATE 1. 



Adults in spring. — Length, 12.50-15. Wing, 5.75. Above, blackish ; below, 

 silky white, lower neck, breast and sides rufous ; a dense tuft of ochraceous 

 feathers on each side of the head, throat and sides of upper neck, black ; sec- 

 ondary wing feathers, white. 



Adults and young in winter. — Similar, but duller, and lacking the rufous 

 breast and ochraceous plumes. 



A tolerably common winter resident on the coast and bay, rather 

 plentiful in migrations, which seem to occur in late October and early 

 November, and during March and April. We have numerous records 

 in the vicinity of Philadelphia, April 7th to 29th. The latest New 

 Jersey record that I have seen was May 3d. It occurs also regularly 

 on the Delaware and other streams, and on ponds in the interior. 



This and the following are the birds popularly known among gun- 

 ners as "Hell-divers," and are to be seen swimming about, generally 

 singly, with the body low in the water and the neck erect. They are 

 good swimmers and still better divers, disappearing instantly at the 

 discharge of a gun or other cause of alarm.
