1879, a pair of Swifts was seen at Concepciou ha\ing the general 

 appearance and motions of Chcetura pelagica. No specimen 

 was secured, and no otiiers were afterward seen. 



106. Campephilus boiaei ( WagL). — A part of the hist week 

 in April, 1880, was spent in a considerable tract of forest Ijorder- 

 ing a stream known as the "Arroyo Gualeguaychu" at a point 

 about twenty miles west of Concejjcion. The wood borders the 

 stream to a depth of a mile or more on each side and stretches up 

 and down stream indefinitely. It had snftered comparatively 

 little from the axe of the charcoal burner, and many birds, not else- 

 where seen, were met with here. Among these was the present 



.beautiful Woodpecker, of which, howe\'er, only a single pair 

 was observed, and the male alone taken. It is said to occur 

 sparingly in all the large forests. 



107. Picus mixtus Bodd. — Resident; not common; seen 

 only about a dozen times, usually in low and swampy growths, 

 where its tapping was the only sound heard from it. It was 

 always solitary. 



108. Picus cactorum Lafr. et d'Orb. Carpinterito 

 (Little Carpenter). — Resident. More commonly met with 

 than the preceding, but abundant only on the Gualeguaychu at 

 the place mentioned aboye. 



109. Chrysoptilus cristatus ( I7£?///. ). — Resident. Abun- 

 dant in ^voods everywhere, and conspicious for its activity, bright 

 colors and large size. It is strictly arboreal, but hops about among 

 twigs and small branches more freely than most Woodpeckers of 

 my acquaintance. September 29, two pairs of these birds were 

 seen near holes in inaccessible dead stubs overhanging a stream. 

 The specific name implies a crest, \vhich the bird has not. 



no. Leuconerpes candidus (O/Zc). Carpintero blanco 

 (White Carpenter). — Sparingly resident and doubtless breeds. 

 Its snow-^yhite body, black wings, and noisy habits, prevent its 

 being often overlooked, but it is nevertheless seldom seen about 

 Concepciou, and then only in the heavy timber. 



III. Colaptes agricola Malh. Carpintero (Carpenter). 

 — Abundant and breeding at all points visited. At Concepciou. 

 where it is resident, it is by far the commonest Woodpecker. 

 The ordinary note very much resembles the reiterated alarm note 

 of the Greater Yellow-legs {Tota?ms melanoleucus) , but so loud 

 as to be almost painful when close at hand, and easily heard a
