Azara says it is called _Chochi_ in Paraguay, and has a clear sorrowful note of two syllables, which it repeats at short intervals during the day, and also at night during the love-season. It is solitary, scarce, and excessively shy, escaping on the opposite side of the tree when approached, and when seen having the head and crest raised in an attitude of alarm. In the northern part of the Argentine country it is called _Crispin_, from its note which clearly pronounces that name. Mr. Barrows found it common at Concepcion on the Uruguay river, and has written the following notes about it:-- "Several were taken in open bushy places, and many others were heard. It is a plain but attractive Cuckoo with a few-feathered crest, and long soft flowing upper tail-coverts. The note is very clear and penetrating, sounding much like the word 'crispin' slowly uttered, and with the accent on the last syllable. The birds are very shy, and I followed one for nearly an hour before I saw it at all, and nearly twice that time before any chance of a shot was offered. There is some peculiarity in the note which makes it impossible to tell whether the bird is in front of or behind you--even when the note itself is distinctly heard. I know nothing of nest or eggs." From personal observation I can say nothing about this species, as I never visited the district where it is found; but with the fame of the Crispin I have always been familiar, for concerning this Cuckoo the Argentine peasants have a very pretty legend. It is told that two children of a woodcutter, who lived in a lonely spot on the Uruguay, lost themselves in the woods--a little boy named Crispin and his sister. They subsisted on wild fruit, wandering from place to place, and slept at night on a bed of dry grass and leaves. One morning the little girl awoke to discover that her brother had disappeared from her side. She sprung up and ran through the woods to seek for him, but never found him; but day after day continued wandering in the thickets calling "_Crispin, Crispin_," until at length she was changed into a little bird, which still flies through the woods on its never-ending quest, following every stranger that enters them, calling after him "_Crispin, Crispin_," if by chance it should be her lost brother. 270.
