18. Haematopus ostralegus picatus . Northern Pied Oyster- 

 catcher. 



Haematopus picatus King, Survey Intertrop. Coast Austr. 

 1826, p. 420: Point Torment, North-west Australia. 



Fairly common, but very wary ; one flock of twenty was 

 seen.

A pair came near Apsley Straits on the 1st of December 

 and again on the 3rd of February. Another pair was

 Plover. 



Charadrius hypomelus Pallas, Reise Russ. Reichs, vol. iii. 

 1776, p. 699: Siberia. 



This species is rare on the Island, only a few being seen 

 in November and December ; after the 13th of the latter 

 month no more were observed till April, when they were in 

 twos and threes with other Waders, but never in flocks by 

 themselves.

 Charadrius fulvus Gmelin, Syst. Nat. 1789, p. 687 :

A few were seen at difi'erent times ; they were not nearly 

 so wild as Mr. Rogers found them at Point Torment in 

 north-west Australia. None were seen on the north side 

 of the Island or anywhere else after the 3rd of February, 

 1912, until April, when small flocks appeared.
