I'm Tiffany Kersten, a professional bird guide based in the Rio Grande Valley of Texas. I spent 2021 traveling, birding, and gifting personal safety alarms to women birders I met on the trails along the way during my Lower 48 States Big Year. In 2022, I founded Nature Ninja Birding Tours, offering customized private tours in the Rio Grande Valley and beyond.


Hi! I'm Tiffany Kersten, a Wisconsin native, turned Texan by way of New Jersey, Massachusetts, and Hawaii. I hold a B.S. in Wildlife Ecology from Northland College, have been a Certified Interpretive Guide through the National Association for Interpretation, and spent over a decade as an environmental educator. I've taught about raptor identification and migration with the Cape May Bird Observatory, monitored shorebirds on Cape Cod, banded Honeycreepers in Hawaii, and finally landed in South Texas where I first worked at Santa Ana National Wildlife Refuge, then Quinta Mazatlan World Birding Center, and managed the McAllen Nature Center, before completing a Lower 48 States Big Year in 2021, and founding Nature Ninja Birding Tours in January of 2022. I have been connecting people to nature through the joy of birding since 2006.
