I still remember the day that sparked my love for birds. I was just a kid, sitting in my backyard, when a tiny bird landed near me. It moved so fast, its feathers flashing in the sunlight, and then it sang—soft, clear, and almost magical. In that moment, birds became more than just creatures in the sky. They became a mystery I wanted to solve.
That curiosity never faded. It led me to study Biology at the University of Scranton, where I dove deep into the science of birds—their behavior, their calls, and the incredible ways they survive. Today, that same passion drives me, and through Earth of Birds, I get to share it with you.
