🐦Brown-headed Cowbird
שחרורית חומת-ראש (שם מדעי: Molothrus ater) היא ציפור שיר קטנה ממשפחת הפזאיים, טפילת תטולה הנפוצה באמריקה הצפונית, הממוזגת והסובטרופית. זהו מין יציב בחלקים הדרומיים של אזור תפוצתו; אך האוכלוסיות הצפוניות נודדות לדרום ארצות הברית ולמקסיקו בחורף, וחוזרות לאתרי הקינון שלהן בקיץ בסביבות מרץ או אפריל.
