Birds of Uruguay. 199 



*Ardetta involucris. Variegated Heron. 

 A specimen in the Museum of Montevideo. 



94. Nycticorax obscurus. Dark Night Heron. 



I shot an immature specimen as it sat in a willow on the 

 Monzon on 22nd February. As it sat its body was held in 

 a nearly horizontal position. 



95. EuxENURA MAGUARi. Maguari Stork. 



The locusts visited our part of the country in November^ 

 arriving on the 23rd. A day or two after some Storks 

 arrived^ but only three or four. I saw one at Sta. Ana on 

 the 29tli. Riding from Porongos on the 22nd December^ I 

 saw two and another on the wing. About the middle of 

 March I again saw one at Sta. Elena^ and on various occa- 

 sions in that month, April, and May 1 met with them. When 

 the bird is on the wing the neck is outstretched and deflected. 

 On rising, this Stork puts its head down very low and takes 

 two or three long bounding hops before it gets on the wing. 

 Legs and feet blood-red ; bill lead-grey. 



-f- 96. Tantalus loculator. Wood Ibis. 



Mr, Burgess found this bird breeding on the coast of the 

 other Arroyo Grande, which flows into the Rio Negro from 

 the north, some years ago. The birds were in a small colony, 

 and the nests were on big tumps of grass in a marshy place. 



97. Phimosus infuscatus. Whispering Ibis. 



I met with this species only twice, viz. on the 11th February 

 and 1st April; on both occasions the bird escaped wounded; 

 the first, indeed (at which my companion and I only got flying 

 shots with our revolvers), was found dead a few miles away 

 some days after. It once uttered a low croak when flying. 



~ 98. Ajaja rosea. Roseate Spoonbill. 



I saw the skin of one which had been killed on the Rio 

 Negro shortly before. 



■^Phcenicopterus ignipalliatus. Argentine Flamingo. 

 A specimen in the Museo de Historia Natural, from 

 Maldonado.
