As you're getting ready to watch the Buckeyes play the Iowa Hawkeyes today--we thought we'd reflect on some other hawks you might see in Ohio. We found some in our Museum of Biological Diversity's research collections! You can join us in the spring for our Open House event on Saturday, April 3, 2027!
The Red-Tailed Hawk is a common permanent resident hawk of Ohio. It is known for its rusty-colored tail and its broad wings used for soaring.
Did you know the Bald Eagles are also considered hawks? This eagle is a juvenile and has not developed the classic white head you might be familiar with!
The Cooper’s Hawk and Sharp-Shinned Hawk are often confused for one another due to their similar plumage. The most striking difference between the two is their sizes. Cooper’s Hawks are much larger than Sharp-Shinned Hawks. You might also notice the difference in their tail feathers: Cooper’s Hawks have a much more rounded tail compared to the Sharp-Shinned Hawk which has a more squared-off tail.
What birds have you seen around Ohio or on campus?

Please take a look at a new publication by EEOB's own Santos' Lab in the journal Evolution about "Integration promotes morphological innovation in deep-sea anglerfishes (Eupercaria: Lophiiformes." They say: "We used micro-CT scans of 100 species of anglerfish in this study."
Congratulations. Dr. Liz Santos and colleagues!

How well did you do? Let us know in the comments below.

Although the skulls look similar, the differences between the bears are very clear. Size, of course, is the most notable difference between them all. The brown bear skull, although not the biggest bear on average, has generally larger skulls than those of polar and black bear skulls. Their teeth give clues about their mostly carnivorous diets, especially in polar bears, but some teeth hint at the omnivorous diet of black and brown bears. The molars of black and brown bears are flat while the molars of polar bears are more sharp and serrated like a knife!

Thank you .tetrapods and @osu for your help and sharing these specimens!
