The American Birding Expo will return Sept. 21-23 to the Greater Philadelphia Expo Center, 100 Station Ave., Oaks, Pennsylvania.

This weekend will provide a stepping stone in advancing birding interest and expertise. The expo will provide the opportunity to learn about the latest in outdoor gear, accessories, optics, cameras and other equipment, as well as nature tours to worldwide destinations, special presentations, bird walks and demonstrations.

More than 100 exhibitors worldwide will be on hand to share expertise with birders and other nature enthusiasts ready to move to the next level of experience. New to the expo is the opportunity to field test the many kinds of optics on the market in an indoor optics range. The range realistically simulates outdoor birding conditions, allowing consumers to test optics side-by-side.

Free morning bird walks will be held at 7:30 a.m. daily. These two-hour walks bring new and seasoned birders together. Starting at various locations convenient to the Expo Center, these walks offer an opportunity to see the panoply of native birds while learning from the guides from area bird clubs.

Another opportunity open to birders and nature enthusiasts of all skill levels are the keynote presentations that take place each evening. These presentations by some of the best-known names in the birding community will offer a front-row seat into the diversity of this pastime.

Presenters include self-proclaimed “bird-nerd,” humorist and author Noah Strycker, who became the first human to see more than half the planet’s bird species in a round-the-world birding trip. Film and TV actor Lili Taylor will deliver a special presentation on how her two loves have come together as she reveals how the techniques she uses as an actor are great assets for being a birder.

On “Family Day Sunday,” Sept. 23, Carrie Barron, assistant director of the John James Audubon Center, will be joined by an eastern screech owl and a barred owl for a presentation that offers a window into these predators of the sky and the adaptations that have made them so deadly.

The first two days, Sept. 21-22, offer a schedule of daytime presentations and activities presented by experts covering topics such as photography, international conservation efforts, bird-watching skills, gardening, technology, travel, ecotourism and optics.

A portion of the entrance fee, sponsor contributions and fund-raising programs support the Expo Conservation Fund which provides conservation and environmental education. The fund also supports BirdLife International’s efforts to protect critically endangered bird species, as well as the American Birding Association and their work in protecting the declining rufa red knot.

The $10 entrance fee covers the three days; children 17 and younger are free.
