- buildsjets 2y agoUh, no. That would be WAY too expensive and difficult to automate. They run off of propane. Search your favorite engine for “bird scare cannon”. Or buy this one off amazon. https://www.amazon.com/SlavicBeauty-Wildlife-Propane-Scarecrow-Mechanical/dp/B07HQ2BRH3 https://www.amazon.com/SlavicBeauty-Wildlife-Propane-Scarecr...
- kijin 2y agoNot sure what they use in Delhi, but here in Korea we actually have rangers who shoot blank rounds at birds to chase them away at airports. See first photo in https://www.yna.co.kr/view/AKR20230307131700056 https://www.yna.co.kr/view/AKR20230307131700056 (article in Korean) The machine in the second photo looks like a cannon but actually sprays insecticide. The goal is to remove insects that the birds feed on, giving them less reason to approach the area in the first place. Due to the proximity of most Korean airports to residential areas and important military targets, an automated cannon that makes explosive sounds at random would be a big no-no. People would think the airport was being bombarded, or more likely, the President had declared martial law again :(
- seoulbigchris 2y agoI live less than a km from a small airport in South Korea, and hear that "cannon" going off all the time. Now I'm curious, is it propane or a person? I'm going to be on the lookout now.
