Black Swans were numerous on Lake Muir in 191G and 

 1019, wbile a good many were seen at Augusta (near the 

 mouth of the Blackwood River) and also on the Swan 

 River. The aboriginal name for this species about Lake 

 Muir is " Mar-lee." 



Casarca tadornoides australis. 



Mountain Ducks were very scarce at Lake Muir in March 

 1919, where they usually occur in thousands, the reason

 ever previously known, and the water was almost fresh. 

 This fulness of the lake was remarkable, as the 1918-19 

 season was most exceptionally dry and hot. These ducks 

 were plentiful there in January 19 IG, when the water was 

 very low and salt, so low that it was almost impossible to 

 shoot any, owing to absence of cover from which to approach 

 the edo-e. A'^erv large flocks of these birds were seen on 

 24 May, 1919, at a salt lake one hundred and forty miles 

 east of Perth. 



Anas superciliosa rogersi. 



Black Ducks were plentiful in the large freshwater lakes 

 near Lake Muir in January 191G. I saw a brood of nine 

 young in down only a few days old on 29 January, and 

 Mr. Muir told me that he saw two similar broods on other 

 swamps about the same date. In the south-west area this 

 species usually breeds from July to September. From the 

 middle of April until the end of May in 1919 tnere M-ere
