ILEMATurUDlD.K — TUE OYSTER CATCHERS — H/EMATOPUS. 115 



■watchful and stately manner, from time to time probing tlie ground with its bill in 

 searuh of food. The hard sand to wliicli it resorts was found thickly perforated with 

 oblong holes two or three inches in depth. Tlie fiddler-crab, as well as mussels, sport- 

 fish, and a variety of other shell-tish and sea-insects, with which tliose shores abound, 

 were its principal food. The inhabitants of I'^gg Harbor and those of otlicr parts of 

 the coast did not credit its alleged feeding upon oysters, stating that it is never seen 

 in tlieir neighborhood, but confines itself solely to the .sands ; and this statement 

 Wilson confirms, stating that he has uniformly found it on the smooth beach border- 

 ing the ocean; and on the higher (h-y and h-vel sands, just beyond the reach of tides, 

 and at points wliere the dry fiats are thii'kly intersjiersed with drifti'd shells, he 

 usually found its nests between the middle and the 2oth of jVIay. The nest is said 

 to be merely a slight hollow in the saud, and usually contains three eggs, which, when 

 fresh, have a bluish cream-colored ground, marked with large roundish spots of black, 

 aiul otliers of a fainter tint. In some eggs this blue tint was wanting, and in these 

 the blotches were larger and of a deep brown. The young were hatched about the 

 25th of May, and sometimes earlier ; Wilson himself found them running about the 

 beach at that period. When I visited the sandy islands off Cape Charles in June, 

 18~>'2, there were no young birds found, and all the eggs of this species were fresh — a 

 condition probably owing to the fact that their eggs had been previously taken, and 

 no opportunity afforded for their hatching at an earlier period. The young birds are 

 described by Wilson as being at first covered witli down of a grayish color, resembling 

 that of the sand, and marked with a streak of blackish brown on tlie neck, back, and 

 rump, the breast being dusky where in the old birds it is black. Their bills are 

 slightly bent at the tip, and have a hard protuberance, which falls ojff in a few days 

 after they are hatclied. They run along the shore with great ease and swiftness. 

 The female sits on her eggs only during the night or during cold and rainy weather, 

 the heat of the sun and of the sand at other times rendering her presence unneces- 

 sary ; but she is said to watch the spot with anxiety and fidelity. The young follow 

 the mother from the shell, squat on the sand — from which they are with difficulty 

 distinguished — whenever there is any danger, while both parents make large circuits 

 around the intruder, uttering repeated cries, and practising the common stratagem of 

 counterfeited lameness. Their note is said to be a loud and shrill whistling, like 

 tvheejJ-wheep-whed sharply uttered. A flock of these birds will often rise, descend, 

 and wheel in air with remarkable regularity, as if drilled to the practice ; at such 

 times the glittering white of their wings is very conspicuous. This peculiarity is 

 also mentioned by Jardine as having been noticed by him in the European ostralegus. 

 The stomachs of the birds opened by Wilson contained fragments of shell-fish, 

 pieces of crabs and of the great king-crab, with some dark brown marine insects. 



Audidjon claims to have met with this si^ecies in Labrador, and states that he 

 there found several breeding in the month of July. He afterward adds that he saw 

 this bird farther inland in Labrador than in auy other part of the country. I am 

 only able to reconcile this statement with the remarkable rarity of this species from 

 Montauk Point to Grand Menan, and witli the singular fact that we have no mention 

 by any other author of its appearance on that coast, by supposing that Mr. Audubon 

 was misinformed, or in some way misled in regard to its occurrence farther north. 



The eggs of this species vary in length from 2.25 to 2.45 inches, and in breadth 

 from 1.65 to 1.70 inches. Their groimd-color is a fawn-colored white, and their 

 markings are of bistre ; these are partly rounded spots, and partly irregular confluent 

 blotches, lines, and oblong dashes. The dark-bistre is occasionallj' washed with the 

 fawn-color of the ground, giving to these markings a diluted, neutral appearance.
