BIRDS OF ARGENTINA, PARAGUAY, URUGUAY, AND CHILE 211 



series from Formosa and Paraguay the barring on the foreneck is 

 restricted or absent, a distinction seen without difficulty in comparing 

 specimens. In describing pilcomayensis, Hargitt chose a specimen 

 without a label, and assumed that it came from the " Rio Pilcomayo." 

 He mentions a second male secured near Empedrado (a short distance 

 below Corrientes), and therefore not far from Resistencia and Las 

 Palmas, both this bird and the type being of the form with barred 

 neck as nearly as may be determined from his description. He also 

 had a third specimen, a female from Fortin Page on the Pilcomayo. 

 Kerr ^^ lists only two specimens. No. 6, which by reference to Hargitt 

 we learn comes from an island opposite Empedrado, and No. 125,. 

 a female shot at Fortin Page on the north fork of the Pilcomayo. 

 Kerr mentions that he found this bird on the Pilcomayo, at Puerto 

 Bermejo, and on an island in the Parana opposite Empedrado. Ob- 

 viously Hargitt's unlabeled type may have come from any of these 

 regions. Since on geographical grounds the bird from Fortin Page 

 should resemble the light-breasted form from the interior of Formosa 

 and from Puerto Pinasco, by inference it is possible that the type of 

 pilcomayensis^ if of the barred-throated form, may have come from 

 near either Empedrado or Puerto Bermejo. Until this specimen 

 is examined with the female from Fortin Page, the two forms, one of 

 them undescribed, here included can not be successfully differ- 

 entiated.

This piculct was found in tangles of low brush and vines at the 

 borders of tracts of forest, often in company with the little bands 

 of flycatchei's, tanagers, wood hewers, and formicariids that trav- 

 eled in congenial companies in search for food. The piculets 

 were found frequently in pairs, though the season was winter. They 

 ranged in such tangled cover, and clambered, climbed, and hopped 

 about so actively, that one seldom caught more than a glimpse of 

 them, as their tin}' size made it difficult to follow their course. At- 

 tention was usually drawn by their high-pitched calls tse-re tse-rCy 

 or by their pecking at some bit of bark. In general appearance and
