Differences between Big Red and Ezra:
“The female, nicknamed ‘Big Red’ in honor of Cornell University, is noticeably larger, with a darker head, nape, and throat. She has a numbered band on her right leg. ‘Ezra’, named after Ezra Cornell, the founder of Cornell University, is banded on his left leg. He’s smaller and has golden-tawny feathers on his face and head, and a paler neck than Big Red.”
