Oh brother! April 10 is National Siblings Day, a time to celebrate the special bonds shared by brothers and sisters. From friendly rivalries to shared memories, there's nothing quite like the relationship between siblings. Siblings Day was created by Claudia Evart in memory of her siblings Alan and Lisette. Today, it is recognized by 49 states and 14 countries. Celebrations of this day can range from something simple, like phoning your siblings to let them know you're thinking of them, to giving gifts or sharing a meal.

In today's image, we see four burrowing owls in Wyoming, standing near their burrow, looking like a band of mischievous siblings. Known for their distinctive white eyebrows and yellow eyes, these owls are active during the day, hunting insects and small mammals. Just like siblings, they often look out for each other, warning one another of predators by listening out for prairie dogs' alarm calls. So, how are you going to celebrate this Siblings Day?
