National Geographic just released their ‘Best Photos of 2019’ a daunting task given the thousands of photos they receive each year.

Here are a few of our favorites:

An orphaned giraffe nuzzles a caregiver at Sarara Camp in northern Kenya. Samburu cattle herders found the abandoned calf and alerted Sarara—known for raising orphaned mammals and returning them to their habitat. The young giraffe now lives with a wild herd. PHOTOGRAPH BY AMI VITALE.
