(Photo: SUTD)\n    \n\n\n\n\nPeregrine falcons typically nest on loose gravel substrate, where they can scrape out a hollow to hold the eggs, said Dr Malcolm Soh, principal wildlife researcher at National Parks Board (NParks).\nHence, the absence of a suitable substrate, or surface, in the bare concrete recess likely affected nesting success, he said.\n\n\n\n\n\n      A peregrine falcon sitting on a ledge at OCBC Centre in Singapore's central business district on Nov 22, 2024.

(Photo: CNA/Syamil Sapari)\n    \n\n\n\n\nRETRIEVING THE ABANDONED EGGS\nThe crevice where the falcon laid its eggs is about 9m above the 34th storey of OCBC Centre.\nWhen it became clear that the eggs had been abandoned, Dr Soh approached a team of robotics researchers from Singapore University of Technology and Design (SUTD) for help in reaching the crevice. \nThey designed a device mounted on a telescopic tripod, which they dubbed ERNEST - short for Egg Retrieval and Nesting Enhancement Support Tool.\nOn Oct 29, the team used it to retrieve the two abandoned eggs.\n\n\n\n\n\n      The SUTD team operating the Egg Retrieval and Nesting Enhancement Support Tool (ERNEST) device to retrieve the abandoned peregrine falcon eggs. (Photo: NParks)\n    \n\n\n\n\n\n\n      Among the key design considerations: Holes on the gripper claw that would allow it to hold the abandoned eggs safely. (Photo: NParks)\n    \n\n\n\n\nThe eggs were taken to Lee Kong Chian Natural History Museum, where researchers determined that they were likely to have been abandoned by the parents due to shell damage.\nOne egg was much lighter and had a small crack and a sulphurous smell, suggesting it had decomposed. The other egg, while intact, was likely viable but non-fertile, Dr Soh said.\nTo improve the falcons' chance of success, he and his team recommended setting up a nesting tray with loose gravel in the recess.\nOn Nov 22, workers climbed up a scaffold set up on the 34th floor, to put the nesting tray in the crevice.\n\n\n\n\n\n      The scaffolding on the 34th storey used to reach the crevice where workers set up the nesting tray on Nov 22, 2024.

When they hunt, they soar to great heights and dive steeply - known as stooping - reaching speeds in excess of 300 km/h, making them the fastest animals on the planet.\nThe falcons usually nest on limestone cliffs, but the absence of such a setting in Singapore means that they have to find buildings that resemble that, Dr Soh said. \nHe pointed to how peregrine falcons in the UK too, are often known to nest in urban buildings.\n\"For these peregrine falcons to nest here (in Singapore's CBD), it shows that they're quite adaptable. So as long as the conditions are right for them and they have a ready food source, they can adapt somewhat to changing conditions,\" he said.\n\n\n\n\n\n      A peregrine falcon flying near OCBC Centre in Singapore's central business district Nov 22, 2024.

(Photo: NParks/Max Khoo)\n    \n\n\n\n\n“What we're trying to do here with the nesting tray, is to provide a bit more of a suitable habitat for these peregrine falcons so they have a better chance of breeding success.”\nIn other places where nesting attempts have failed on a few occasions, the breeding success increases if a nesting tray with the right sort of substrate is provided, Dr Soh added.\n\n\n\nNEXT NESTING ATTEMPT EXPECTED IN JAN OR FEB 2025\nPeregrine falcons are among the most widely distributed birds in the world, found on every continent except Antarctica. They thrive in diverse habitats, nesting in tall buildings and bridges in the absence of cliffs.\nHowever, for a species so widespread, very little is known about the tropical subspecies that lives in Singapore. \n\n\n\n\n\n      The peregrine falcons' urban diet often includes pigeons and other city birds. Here, a peregrine is seen with the remains of its prey, believed to be a rock pigeon. (Photo: CNA/Syamil Sapari)\n    \n\n\n\n\n\n\n      A peregrine falcon flies off, leaving the remnants of its prey - likely a pigeon - on a ledge at OCBC Centre on Nov 22, 2024. (Photo: CNA/Syamil Sapari)\n    \n\n\n\n\n\n\n      Peregrine falcons' long, tapered wings reduce drag and allow for incredible precision in flight increasing its speed and maneuverability. (Photo: CNA/Syamil Sapari)\n    \n\n\n\n\n“The whole point is to monitor whether or not these birds would take to the nesting tray and breed there,” Dr Soh said. This would help them learn more about how peregrine falcons breed in tropical climates. \nHe added that the information would help them look into other aspects of the ecology, like their diet and what they’re foraging for.\n\n\n\n\n\n      Peregrine falcons regurgitate the indigestible parts of their prey, such as feathers and bones, in the form of pellets, like this one found at OCBC Centre on Nov 22, 2024. (Photo: CNA/Syamil Sapari)\n    \n\n\n\n\nThe expected nesting period for the falcons is between end January and early February 2025. \nIf nesting is successful, the eggs are expected to hatch in March, with chicks fledging in April.","kind":"highlight","is_publish_news":true,"is_publish_highlight":false,"is_publish_live":false,"is_publish_wemedia":null,"editions":null,"column":"","sentiment":"0","news_tag":"","news_rank":0,"symbols":[],"gpt_button":0},"commentList":[],"isCommentEnd":true,"newsSizeData":{"likeSize":0,"commentSize":0,"repostSize":0,"favoriteSize":0,"likeStatus":false,"favoriteStatus":false},"APP":{"userAgent":"Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; ClaudeBot/1.0; +claudebot@anthropic.com)","isDev":false,"isTTM":true,"deviceId":"web-server-community-laohu8-v3","version":"4.29.3","shortVersion":"4.29.3","platform":"web","vendor":"web","appName":"ttm","isIOS":false,"isAndroid":false,"isTiger":false,"isTHS":false,"isWeiXin":false,"isWeiXinMini":false,"isWeiBo":false,"isQQ":false,"isBaiduSwan":false,"isBaiduBox":false,"isDingTalk":false,"isToutiao":false,"isOnePlus":false,"isHuaWei":false,"isXiaomi":false,"isXiaomiWebView":false,"isOppo":false,"isVivo":false,"isSamsung":false,"isMobile":false},"href":"/m/news/2485735510"}
