About Me

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.


For every $10 raised, one personal safety alarm (retail $30) will be purchased from She's Birdie and gifted to a woman I meet during my guiding or on my birding adventures. If you are inspired to donate, you may do so here: http://gf.me/u/zk4n6t

Guiding Rates & Information

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 guide primarily in the Rio Grande Valley of Texas, offering half day, full day and multi-day customized itineraries for individuals and small groups. 

Below is my information for customized, private day tours in the Rio Grande Valley. For information on set departure tours in the Rio Grande Valley and to Panama, visit here

I am currently booking for all 2022 and 2023 dates. A non-refundable deposit of $100 per day is due to reserve the dates, payable by Venmo (+5% to cover fees), PayPal (+5% to cover fees), or a mailed check. The remaining balance is due upon completion of the tour, payable by the above methods, or by cash.

COVID Policy & Driving options:

Due to the Covid-19 Omicron Variant: Until further notice, I will be meeting all clients onsite and we will caravan from site to site. 

Please note: I do not carry commercial vehicle insurance and therefore cannot take clients in my personal car. Be sure to plan your trip accordingly. You will not need four wheel drive or high clearance for any of the sites in the Rio Grande Valley. 

Guiding Fee: Guiding fee only; it does not cover your party's site entrance fees, snacks, or meals. 

Food: We can either stop somewhere for a quick lunch, or you can bring snacks or a sack lunch to be eaten onsite at one of the birding sites. Fully up to you! If you would like to stop for lunch, please let me know in advance so we can work it into the itinerary in a way that makes sense. 

Rio Grande Valley Lodging Suggestions (listed alphabetically by city):

Alamo: Alamo Inn B&B. Nice, budget-friendly rooms with various layout options.
