Summary for migrant species:

Five rarities were recorded in December, including a species new to Singapore. The Amur Falcon Falco amurensis that arrived in November was still around at Lorong Halus / Punggol until 14 Dec 2021. Amazing photos by Lai Yeu Huan show the falcon stealing katydids carried by flying Digger Wasps Sphex diabolicus, with the wasp letting go of the katydid at the last moment. The kleptoparasitic behaviour was repeated many times, allowing other photographers to also capture the theft on camera.

On 9 Dec 2021, a Rufous-bellied Eagle Lophotriorchis kienerii was photographed at Kranji Marshes. A Black Kite Milvus migrans showed up at the Neo Tiew area on 12 Dec 2021 and was recorded sporadically through the month.

On 8 Dec 2021, a single Himalayan Vulture Gyps himalayensis was seen at Dairy Farm Nature Park, and at the Botanic Gardens. Then on 27 Dec 2021, a flock of five vultures were seen flying over Tan Tock Seng Hospital towards Orchard Road area. Those following the vultures over the next few days eventually found them perched in the vicinity of the Botanic Gardens, and they were astonishingly in the company of a Cinereous Vulture Aegypius monachus, a first record!
