There are a couple of small ponds in Sarue Koen, where some ducks come to winter every winter.
Spotbilled Ducks (Karugamoカルガモ) and Pintails (Onagagamoオナガガモ) didn't seem to mind me getting close to them.
A male Kingfisher (Kawasemiカワセミ) came and started fishing.
He was diving in the water and perched in different places but we didn't see him catch anything...
During our stay there for 15 minutes or so, we saw Great Tits (Shijuukaraシジュウカラ), Japanese White-eyes (Mejiroメジロ), Brown-eared Bulbuls (Hiyodoriヒヨドリ), Azure-winged Magpies (Onagaオナガ), White Wagtails (Hakusekireiハクセキレイ) and Thick-billed Crows (Hashibutogarasuハシブトガラス).
