Happy Birthday, Margaret! Climbing to new heights is your specialty—both literally and academically. You've spent years swinging from treetops and exploring leafy canopies with fearless curiosity, making the rest of us reconsider our fear of ladders. Your incredible work through books like "Life in the Treetops" has not only entertained readers everywhere but inspired countless others to explore nature's vertical frontier.Congrats on continuing a remarkable journey full of scientific adventures (and managed mosquito bites). On this birthday, we wish you humor thicker than tree bark, wisdom taller than redwoods—and may gravity always be gentle upon descent!
