"Bald eagles will use the same nest for years, even decades, adding new material to it at the beginning and throughout the nesting season," Eppley wrote. "Normally, they are highly skilled at snapping branches off of trees while in flight. Possibly tired from working nonstop all morning on a new nest, this particular bald eagle wasn't showing its best form. Yes, sometimes they miss. Although this looks painful, and it might very well have been, the eagle recovered with just a few sweeping wing strokes, and chose to rest a bit before making another lumber run."

The photo was taken in India's Western Ghats.

"This proboscis monkey could be just scratching its nose on the rough bark, or it could be kissing it," Hodan wrote. "Trees play a big role in the lives of monkeys. Who are we to judge?"

"The little raccoon cubs are telling secrets to each other," Piecha wrote.

"Two western grey kangaroos were fighting and one missed kicking him in the stomach," Scaddan wrote.

"This raccoon spends his time trying to get into houses out of curiosity — and perhaps also to steal food," de Vaulx wrote.

"A young bear descending from a tree looks like it is playing hide and seek," Marchhart wrote.

"I spent my days in my usual 'gopher place' and yet again, these funny little animals haven't belied their true nature," Kranitz wrote.

"An elephant expresses his joy in taking a mud bath against the dead trees on the shores of Lake Kariba in Zimbabwe on a hot afternoon," Jauron wrote.

Elephants bathe in mud to form a protective layer that keeps them from getting too hot.

Jauron took the photos in Matusadona Park in Zimbabwe.

Elephants use tree trunks to scratch itches they can't reach.

"A smooth-coated otter 'bit' its baby otter to bring it to and fro for a swimming lesson," Teo wrote.

"When this bald eagle missed on its attempt to grab this prairie dog, the prairie dog jumped towards the eagle and startled it long enough to escape to a nearby burrow," Trevino wrote. "A real David vs. Goliath story!"

"I was taking pictures of pigeons in flight when this leaf landed on a bird's face," Speirs wrote.

"A golden silk monkey in Yunnan, China," Jensen wrote. "This is actually a show of aggression, however, in the position that the monkey is in it looks quite painful!"
