Kestrel breeding every year on a railway bridge

Kestrels started nesting close to my house on the JR Joban Line near the oblique chord of the iron railway bridge spanning the Tone River in late April.

And by late June the young birds start to leave the nest. This year, three pairs of birds have nested, one has already left the nest, and it looks like the second pair is about to leave the nest. I waited under the bridge for a few days hoping that the birds would leave the nest, but I was not lucky.

The prey is a baby chick of starling.
