:גבתון צווארון
. קטן למדי אבל חסון למראה, בעל מקור חד וזנב קצר
הזכר בולט בראשו הכהה, ובגחונו הצהוב המופרד מהצוואר
. בפס ערמוני, בכנפיו שני פסים לבנים
. לנקבה ראש מקווקו בכבדות, חסרה את הצווארון ומפוספסת בגבה וצידי גופה
. בית גידולו משתרע מפינלד בצפון דרך רוסיה לרוחבה של אסיה ועד לקמצ'טקה ומשם ליפן
. בית חיותו אזורים חמים ולחים, בחורשים בעיקר של ערבי נחל וצפצפה, לצידי נהרות
. בארץ עובר אורח אקראי או נדיר ביותר לרוב באזור אילת
... תימה מהו אמר לא ידע האי גברא דעוף טהור חייב לשולחי ...חולין קמא, ע"ב
