Differences between Big Red and Ezra:

  • Big Red is larger than Ezra and has a belly band.
  • The black stripe on Ezra’s tail is much more defined than on Big Red’s tail.
  • Big Red is banded on the right and Ezra is banded on the left.
  • Ezra’s scapular “V” is more pronounced than BR’s. Scapulars are small feathers on a bird’s shoulder. In flight, these feathers are at the base of the wing’s leading edge.

  • From the allaboutbirds Red-tailed Hawk Cam FAQ:

“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.”
