Dr. Adolf Doering, of the Argentine University of Cordoba, has been a zealous collector and observer of the birds of the Republic (see under [Cabanis] and [Sclater]). The zoological portion of his report upon the Rio Negro expedition of 1879 gives a list of the birds, which contains 110 species, most of them well-known Patagonian forms.
Henry Durnford, a member of the British Ornithologists’ Union, whose early decease was a severe loss to ornithological science, was a constant worker on birds from the time of his arrival in Buenos Ayres in 1875 until his death in 1878. The birds collected by Durnford are now mostly in the British Museum. His published papers on this subject are the following (see also biographical notice in ‘Ibis,’ 1879, p. 121):—
(1) Ornithological Notes from the Neighbourhood of Buenos Ayres. Ibis, 1876, p. 157.
[Notes made during his first five months’ residence at Belgrano, five miles north-west of Buenos Ayres. About 70 species are mentioned.]
(2) Notes on the Birds of the Province of Buenos Ayres. Ibis, 1877, p. 166, and 1878, p. 58.
[Notes made principally at Baradero, 90 miles W.N.W. of Buenos Ayres. In the first paper 144 species are mentioned and Porzana spiloptera is described and figured as new. In the second 47 species, mostly additional, are noticed.]
(3) Notes on some Birds observed in the Chupat Valley, Patagonia, and in the Neighbouring District. Ibis, 1877, p. 27.
[Durnford first visited Chupat, on the river of the same name, in Eastern Patagonia (43° 20′ S. lat.), in October 1876; 62 species of birds are noted and commented upon.]
