White obtained a single example of this species in the forests of Misiones, near Concepcion, in June 1881.

Fam. XXVI. BUCCONIDae, or PUFF-BIRDS.

The Bucconidae, or Puff-birds, are entirely restricted to the Neotropical Region, and are most numerous in the great forests of Amazonia and Colombia, where most of the 43 known species have been met with. These birds seem to pa.s.s their lives sitting upon the topmost or outermost branches of the larger trees, looking out for insects, which are captured flying and const.i.tute their only food. Southwards of the great forest-districts of South America, Puff-birds become very scarce. One species only is as yet known to occur in Paraguay, and some uncertainty prevails as to the single member of this family stated to be found near Tuc.u.man.

266. BUCCO MACULATUS (Gm.).

(SPOTTED PUFF-BIRD.)

+Bucco maculatus+, _Scl. Jamacars and Puff-birds_, p. 99, pl. x.x.xii.; _Scl. et Salv. Nomencl._ p. 106. +Capito maculatus+, _Burm.

La-Plata Reise_, ii. p. 446.

_Description._--Above blackish, spotted with brown; lores, superciliaries, and neck-collar pale cinnamomeous white: beneath white, fore neck clear reddish cinnamon; breast and belly covered with round black spots; chin and middle of belly whitish; tail black, with transverse bars of pale brown; under wing-coverts and under surface of wings white; bill red, with the culmen and base blackish; feet plumbeous: whole length 80 inches, wing 32, tail 28. _Female_ similar.

_Hab._ S.E. Brazil.

Dr. Burmeister records the occurrence of this species of Puff-bird near Tuc.u.man, and it must therefore be placed in our list on his authority.

But it is possible that the species which he met with may have been the nearly allied _B. striatipectus_ of the Bolivian frontier of Brazil, which is more likely to extend into Northern Argentina than the true _B. maculatus_. _B. striatipectus_ (figured and described in Sclater's 'Monograph of the Jacamars and Puff-birds,' pl. x.x.xiii. p. 101) is very similar to _B. maculatus_, but has the spots on the belly elongated into long striations.

It is again possible that the _Bucco_ of Tuc.u.man may be the Paraguayan _B. chacuru_ of Vieillot, founded upon the ”_Chacuru_” of Azara, which is another species not remotely allied to _B. maculatus_.

Fam. XXVII. CUCULIDae, or CUCKOOS.

The Cuckoos form an extensive and rather varied family of zyG.o.dactyle birds with a somewhat wide distribution, being found in all parts of the world except in the extreme north, where their insect-food would not be abundantly met with. The true _Cuculi_, so remarkable for their parasitic habits, are not found in the New World, but several genera of arboreal Cuckoos (_Coccyzus_, _Piaya_, &c.), and others of terrestrial habits (_Crotophaga_, _Geococcyx_, and _Saurothera_), are met with, chiefly in the Neotropical Region, and number altogether some thirty species. Of these, eight are known to occur within the confines of the Argentine Republic.

267. CROTOPHAGA ANI, Linn.

(BLACK ANI.)

+Crotophaga ani+, _Scl. et Salv. Nomencl._ p. 107; _White, P. Z. S._ 1882, p. 619 (Salta).

_Description._--Black, glossed with bronzy and purplish; bill and feet black; bill with the culmen much elevated, compressed and cultrate: whole length 130 inches, wing 55, tail 70. _Female_ similar.

_Hab._ Veragua and South America down to Northern Argentina.

This strange Cuckoo, with the plumage and some of the habits of a Crow, is of a nearly uniform black, glossed with bronze, dark green, and purple. Its most peculiar feature is the beak, which is greater in depth than in length, and resembles an immense Roman nose, occupying the whole face, and with the bridge bulging up above the top of the head. The Ani is found only in the northern portion of the Argentine territory.

According to Azara it is very common in Paraguay, and goes in flocks, a.s.sociating with the Guira Cuckoo, which it resembles in its manner of flight, in being gregarious, in feeding on the ground, and in coming a great deal about houses; in all which things these two species differ widely from most Cuckoos. He also says that it has a loud disagreeable voice, follows the cattle about in the pastures like the Cow-bird, and builds a large nest of sticks lined with leaves, in which as many as twenty or thirty eggs are frequently deposited, several females laying together in one nest. His account of these strange and disorderly breeding-habits has been confirmed by independent observers in other parts of the continent. The eggs are oval and outwardly white, being covered with a soft white cretaceous deposit; but this can be easily sc.r.a.ped off, and under it is found a smooth hard sh.e.l.l of a clear beautiful blue colour.
