 I could hear no news of any having been seen during my 

 visit to Maspaloraas in February 1912. 



Ardea cinerea. Heron.

Herons are often to be found in the neighbourhood of 

 the Tsleta, and I have several times noticed them fishing on 

 the reef, which is exposed at low tide in Confital Bay. In 

 January 1911^ two were seen there, together with a Curlew 

 and several flocks of small Waders; on being disturbed they 

 flew to the mainland. 



Westwards of Confital Bay a small rock lies exposed some 

 five hundred yards from the Point, and this is a very favourite 

 place for Herons to spend the day. One day in February 

 1912 I counted as many as six at once ; they roost in 

 the high cliffs towards Guanarteme. In the south of the 

 island Herons were noticed daily on the INIaspalomas coast. 

 One bird which frequented the " Charco" was always to be 

 seen in the same place. Herons doubtless breed in the 

 neighbourhood, and Herr von Thanner mentions a young- 

 bird unable to fly which was caught the year previous to his 

 arrival. During a visit which I paid to the island in June of 

 this year, I was informed that a pair of Herons had built a 

 nest on a rock off the Isleta ; unfortunately I had not time 

 to visit the spot myself. 



Anas marmorata. Marbled Duck.

«. ? "Charco," Maspalomas. 24th Feb. '\2. 



Iris dark; bill black, greenish at base ; feet greyish-green, 

 webs black. 



Total length in the flesh 16*2 inches. 



Ducks are generally to be found after a heavy gale 

 frequenting the tanks beyond the golf-links, but hitherto I 

 have failed to procure any. They are occasionally shot at 

 Maspalomas, where Herr von Thanner procured specimens. 

 I have had no means of ascertaining whether the large flock 

 of ducks which visited Las Palmas in March 1911 were of
