The whole family can celebrate the bird migration season at Central Park Conservancy’s annual “On A Wing Festival.” Meet live bats, butterflies, and birds of prey, some of which call the park their home. This afternoon event takes place from noon-3 p.m. on May 7 at Belvedere Castle, mid-park just above the 79th Street Transverse. At noon, the Long Island Aquarium presents “Secret World of Insects and Butterflies” at Shakespeare Garden. At 1 p.m., the Organization for Bat Conservation presents “Live Bat Encounter.” At 2 p.m., Master Falconer Lorrie Schumacher presents “Talons! Live Bird of Prey Experience.” Each hour also offers opportunities to take “A “Birding Basics for Families Walk” to scout out migrating warblers and other songbirds or a workshop “Flight Patterns: Drawing the Shakespeare Garden” led by artist Jessica Daryl Winer at Shakespeare Garden. The afternoon’s events are free and tickets are not required, but to let the Conservancy plan accordingly, RSVP here. For complete information, visit centralparknyc.org.
