:גבתון אדום-מקור | דומה לגבתון גנים, נבדל ממנו בראשו ווחזהו הצבועים בכחול-אפור . ולא בירוק-אפור, הגרון ערמוני ולא צהוב ותחתית הכנף לבנה . הנקבה דהה יותר בית גידולו משתרע במזרח אגן ים התיכון, ממערב הבלקן . לטורקיה ומשם דרומה עד ישראל בית חיותו מדרונות סלעיים דלילי צמחיה. מצוי בד"כ על האדמה . ולא על גבי שיחים, בתקופת הנדידה מצוי גם בקרבת מגורי אדם . בארץ עובר אורח שכיח בסתיו ומצוי באביב ברוב חלקי הארץ . דוגר קיץ שכיח למדי בצפון ובמרכז ... תימה מהו אמר לא ידע האי גברא דעוף טהור חייב לשולחי ...חולין קמא, ע"ב
