Abstract ∙ The Cliff Swallow (Petrochelidon pyrrhonota) breeds in South AmericaWorldwide, the breeding of birds in overwintering areas is a rare phenomenon. The Cliff Swallow (Petrochelidon pyr‐rhonota) breeds in North America and overwinters in South America, and five presumably unsuccessful breedingattempts have been documented during the Austral spring and summer in east‐central Argentina and central Chile.Here we describe the first case of successful breeding of this species in South America. A colony under a concretebridge over the Río Tercero (Villa María, Córdoba, Argentina) succeeded in raising chicks for the first time on the win‐tering grounds. Nest‐building began 10 November 2015, and the last nests were abandoned on 20 January 2016. Of 33finished nests, at least 8 succeeded in raising fledglings that left their nests between 12 and 28 of December. Up to 15fledglings were observed simultaneously around the colony. A nest found on 27 November 2015 some 20 km NE ofVilla Mirasol (La Pampa, Argentina) constitutes a new breeding attempt in a new locality. Given their unpredictablereturn to colonies, it is uncertain whether Cliff Swallows will establish regular breeding populations in South America.It is important to monitor the colony herein described and to survey concrete bridges looking for possible new colo‐nies in Argentina.<!-- --&<!-- /* Font Definitions */@font-face{font-family:"Cambria Math";panose-1:2 4 5 3 5 4 6 3 2 4;mso-font-charset:0;mso-generic-font-family:auto;mso-font-pitch:variable;mso-font-signature:-536870145 1107305727 0 0 415 0;}@font-face{font-family:Calibri;panose-1:2 15 5 2 2 2 4 3 2 4;mso-font-charset:0;mso-generic-font-family:auto;mso-font-pitch:variable;mso-font-signature:-520092929 1073786111 9 0 415 0;}@font-face{font-family:"MS Mincho";panose-1:0 0 0 0 0 0 0 0 0 0;mso-font-alt:"ＭＳ 明朝";mso-font-charset:128;mso-generic-font-family:roman;mso-font-format:other;mso-font-pitch:fixed;mso-font-signature:1 134676480 16 0 131072 0;} /* Style Definitions */p.MsoNormal, li.MsoNormal, div.MsoNormal{mso-style-unhide:no;mso-style-qformat:yes;mso-style-parent:"";margin-top:0in;margin-right:0in;margin-bottom:8.0pt;margin-left:0in;line-height:200%;mso-pagination:widow-orphan;font-size:11.0pt;font-family:Calibri;mso-fareast-font-family:"MS Mincho";mso-bidi-font-family:"Times New Roman";mso-ansi-language:ES-AR;}p.MsoCommentText, li.MsoCommentText, div.MsoCommentText{mso-style-priority:99;mso-style-link:"Comment Text Char";margin-top:0in;margin-right:0in;margin-bottom:8.0pt;margin-left:0in;mso-pagination:widow-orphan;font-size:12.0pt;font-family:Calibri;mso-fareast-font-family:"MS Mincho";mso-bidi-font-family:"Times New Roman";mso-ansi-language:ES-AR;}span.MsoCommentReference{mso-style-noshow:yes;mso-style-priority:99;mso-style-parent:"";mso-ansi-font-size:9.0pt;mso-bidi-font-size:9.0pt;}span.CommentTextChar{mso-style-name:"Comment Text Char";mso-style-priority:99;mso-style-unhide:no;mso-style-locked:yes;mso-style-link:"Comment Text";mso-ansi-font-size:12.0pt;mso-bidi-font-size:12.0pt;mso-ansi-language:ES-AR;}.MsoChpDefault{mso-style-type:export-only;mso-default-props:yes;font-size:10.0pt;mso-ansi-font-size:10.0pt;mso-bidi-font-size:10.0pt;font-family:Calibri;mso-ascii-font-family:Calibri;mso-fareast-font-family:"MS Mincho";mso-hansi-font-family:Calibri;}@page WordSection1{size:8.5in 11.0in;margin:1.0in 1.25in 1.0in 1.25in;mso-header-margin:.5in;mso-footer-margin:.5in;mso-paper-source:0;}div.WordSection1{page:WordSection1;}-->
