Did you know that the iconic cacti of SaguaroNationalPark have a hidden talent? When the wind blows through their spines, they actually whistle (well… more like a hiss)! 🌵🎶 Saguaro cacti, which can grow over 40 feet tall, have a distinctive shape that lets the wind pass through their ribs, creating a cool whistling sound. #Saguaro #Arizona #Cactus #Wildlife #WildlifeWednesday #SaguaroNationalPark #CactiWhistle #DesertFacts #DidYouKnow 📸: NationalParkTrust Video: Cacti whistling in Saguaro National Park
