The Suffolk Owl Sanctuary which is based at Stonham Barns, near Stowmarket, was called to rescue the bird.
The kestrel, which is a small falcon, was seen flying back and forth, along the length of the church.
Attempts were made to try and help the bird fly out of the church with the main and side doors left open.
It was the efforts of Dolly Cook, the hospital lead at the Suffolk Owl Sanctuary that ensured the bird of prey was caught.
Kestrels can live for around four years and are classified as Amber in the UK under the Birds of Conservation Concern.
They are found in urban and remote areas and like to eat small mammals like field voles.
She said: “The porch and the lobby clearly made it far more difficult for it to leave, then it took to enter.
“The side door had also recently been opened in hope it might find its way out, but as we arrived the kestrel was still flying back and forth at height, and even with our tallest net we weren’t able to reach it in the air, but it was seeming to rest on the window frames at either end, which we managed to reach.
“The kestrel decided that the net might make a nice perch instead, which wasn’t very helpful!
“After much success in evading capture, it finally found its way out the side door back out to the big wide world.”
