Gabriel Willow

Gabriel Willow has been a nature enthusiast and birder since he was a small child in rural Maine, roaming the woods and fields in search of frogs and woodcocks. In his teens he traveled to Arizona, Colorado, Utah and Wyoming to study birds, learning how to use mist nets and band birds. He went on to study ecology in college, his studies taking him to the mountains of Vermont and to southern Mexico, where he traveled, studying and painting the endemic avifauna off and on for five years. In 2003 he moved to New York, hoping to pursue an art school dream, but instead was drawn once again to nature and birds, becoming a teacher-naturalist with the Prospect Park Audubon Center and leading tours for Wave Hill, New York City Audubon, and others.

Gabriel is probably best known for leading NYC Audubon's summer and winter eco-cruise program. He's led the program since its inception in 2004. Working with the Prospect Park Audubon Center, Gabriel developed the eco-cruise program to blend social and natural history with wildlife sightings. He also leads migration walks in Bryant Park, in collaboration with the Bryant Park Corporation. These walks have become a regular fixture in the park, and draw a dependable crowd. Visitors are often surprised by the interesting birds that show up in this tiny park in the middle of Manhattan: Recent sightings have included American woodcock, yellow-breasted chat, ovenbird, and Lincoln’s sparrow. In addition to frequent bird walks throughout the city, Gabriel also leads various canoeing and “biking & birding” tours each year.

Joe Giunta, a native New Yorker, has been birding the New York City region for over 20 years. A former math teacher and Program Chairman at Fort Hamilton High School, Joe is the birding instructor for the Brooklyn Botanic Garden. He has led bird walks for New York City Audubon, the Nature Conservancy, and Brooklyn Bird Club, and regularly gives lectures on birding and leads bird walks for the South Fork Natural History Society (SOFO). Joe is the Bluebird Trail coordinator for SOFO on the South Fork of Long Island, and a captain in the Brooklyn and South Nassau Christmas Counts. He has also participated in breeding bird surveys for New York State.

In addition to his popular spring and fall series of morning migration walks in Central Park, Joe leads many birding trips for NYC Audubon to popular birding destinations in the New York City area and beyond, and also teaches classes on bird song and identification. An enthusiastic traveler, Joe has birded extensively in Central and South America. Joe is the owner of Happy Warblers LLC, a birding and educational travel company.

Nadir Souirgi

Nadir SouirgiNadir SouirgiBorn to a Haitian mother and a Moroccan father in New York City - where else? - Nadir learned at an early age that nature is where you see it. This was due in large part to the influence and generosity of Oscar Ruiz, a close family friend, who was an avid birder and amateur naturalist himself. When Nadir was five years old, Oscar started taking him to the local hotspots: Jones Beach, Jamaica Bay, Van Cortlandt Park - and even a three-day trip to the Florida Everglades. Oscar was also responsible for giving Nadir his first set of binoculars and field guide. According to Nadir, “That’s probably why I became a teacher - because of Oscar - he didn’t just teach me about the natural world, he taught me to love it… that also has to be taught.”

And so he teaches… as an elementary school art teacher in East Harlem, through the birding and nature study program he created at his school - The Harlem County Bird Club - and now with NYC Audubon.  “The natural world needs allies, and childhood education is one of the surest ways to create them. I, along with a growing number of birders, am actively seeking to bring greater diversity to the birding and science communities. Again, early intervention is key.” Nadir continues to observe, teach, draw, and learn about birds and science as much as possible, which he does in the field, and as a volunteer in the Department of Ornithology at the American Museum of Natural History.

Peter Mott

Peter Rhoades Mott, past president of NYC Audubon, has been a volunteer for the organization since he moved to New York City in 1984. In previous years, he served as president of the Florida Audubon Society and also conducted field research for Massachusetts Audubon, focusing on problems created by herring gulls and other birds at Logan Airport. Professionally, Peter worked at Phillips Academy, Middlesex School, Moses Brown School, and Saint Luke’s School as a biology teacher and school head before moving to New York City. From that time till his retirement in 2007, Peter taught at the Ethical Culture Fieldston School, where he initiated the Annual Founders’ Day walk in Central Park for Fieldston students and faculty. He also developed records for spring and fall migration at the school’s Riverdale campus.

Mr. Mott grew up with “bird hikes” in central New Jersey and continued his passion for birding with organized trips to special sites in Florida as well as to spectacular locations in France, Kenya, and Nebraska. He now leads several walks each year to favorite birding spots in New York City, where his many years of teaching are apparent as he engages birders with his deep knowledge of our birds and their environment.
