Happy International Owl Awareness Day! To celebrate, here's an owl fact from The Wilson Journal of Ornithology.

Did You Know?

Eastern Screech-Owls’ diets differ depending on their color morph. Gray screech-owls eat fewer birds and more amphibians than red screech-owls.

We dug into the WJO archives to find an interesting Bald Eagle fact in honor of Independence Day. Have a great holiday weekend if you're in the U.S.!

Did You Know?

Bald Eagles will eat loons and loon eggs, and high eagle densities in some areas may even contribute to loon nest failures.

Cooley, J. H., Jr., Harris, D. R., Johnson, V. S., & Martin, C. J. (2019). Influence of nesting Bald Eagles (Haliaeetus leucocephalus) on Common Loon (Gavia immer) occupancy and productivity in
New Hampshire. The Wilson Journal of Ornithology, 131(2), 329–338.
