Mr. H. Durnford on the Birds of 
—71. Coccyzus melanocoryphus (Vieill.) ; Scl. et Salv. 
P. Z. S. 1869, p. 633. 
A spring and summer visitor. Most common about the 
riverain wood. I have not observed Coccyzus cinereus in 
this neighbourhood. 
72. Conurus "patagonus (Vieill.); Scl. et Salv. NomencL 
p. 111. 
Resident, and not uncommon wherever there is a tosca- 
cliff of sufficient height for nesting-purposes. In the clefts 
of this it breeds. It feeds chiefly on buds and the seed of the 
sena-sena, a species of Acacia , very common here. 
73. Bolborhynchus monachus (Bodd.); Finsch, Papag. 
ii. p. 115. 
Last winter I observed two of these birds about ninety miles 
to the south of Buenos Ayres, where they are well known and 
often seen. Specimens are sometimes seen near the city; but 
are probably escaped birds, as it is very commonly kept there in 
confinement. Unlike all other Parrots here, this bird builds 
in trees a large structure of sticks, instead of nesting in holes 
in steep cliffs. 
-(-74. Otus brachyotus (Forst.); Scl. et Salv. P. Z. S. 1868, 
p. 143. 
Resident and generally distributed. Usually seen about 
dusk, when it sallies out from amongst the thistles or coarse 
grass where it has been concealed during the day. 
75. Pholeoptynx cunicularia (Mol.); Scl. et Salv. l.s.c. 
Resident and very common in the spring, retiring to the 
campo to breed, and, as the winter approaches, coming close to 
the towns and villages. When necessary it burrows a hole for 
itself, but makes use of Viscacha holes when possible. They 
are seen during the day and about dusk, and have a curious 
and pretty habit of rising almost perpendicularly from the 
stone or clod of earth on which they have been perching, 
and toying or playing with each other in the air. Their prin¬ 
cipal food is mice. Common at Baradero in April.
