November six to ten eggs, in the grain-fields and other places 

 covered with grasses and a few shrubs. It does not make a 

 nest, but makes a slight hollow in the earth with its feet. 



39. Vanellus Gayennensis, vulg. Gueltregue, lays from July to 

 November two to four eggs, in marshy places. It makes no 

 nest, but hollows out a kind of cup in the clods of earth which 

 are just above the water, and puts in it a few straws ; this con- 

 stitutes its nest. 



40. Ardea egretta, vulg. Garza grande, unites in communities 

 to lay, sometimes upon rocks at the sea-shore, sometimes on the 

 trees in woody ravines, where it builds large nests with branches 

 and grasses. It lays from four to eight eggs from October to 

 November. 



41. Nycticorax Gardenii, vulg. Guayraho, unites in companies 

 to nest. They build near together on the reeds, or on the bushes 

 which surround the marshes. Their nests consist of a heap of 

 bent rushes and little sticks of wood. They lay from three to 

 five eggs in October or November. 



42. Himantopus nigricolUs, vulg. Perrito, lays in November 

 three or four eggs in the marshes. For this purpose it chooses 

 slight elevations, where it lays together a few dry grasses in the 

 form of a nest. It manifests much courage when one approaches 

 its nest. 



43. Ihis melanopis, vulg. Bandurria, in the month of October 

 builds a rude nest in steep and rugged rocks, in which it deposits 

 from three to five eggs. In the provinces of the south, it chooses 

 for its nest the summits of dead, high, and inaccessible trees ; in 

 the north, it retires often for this purpose to the Cordilleras, to 

 the height of seven or eight thousand feet. 



44. Falcinellus guarauna, vulg. Cuervo. These assemble in 

 numerous flocks for nesting, and lay from November to Decem- 

 ber four to six eggs in a nest of rushes, placed in the midst of 



reeds. 



45. GalUnago paraguia, vulg. Porotera, from July to Septem- 

 ber lays two eggs, which it deposits in a rude nest composed of 

 straw and dried grass, in swampy meadows. 



46. Rhynchoea semicollaris, vulg. Abecassina, does not build a 

 nest, but lays in September and October two or three eggs in 

 marshes and inundated fields, depositing them on the mud or wet 

 grass.
