Another block we have been culling forever. We have not been there in a few years as the owners let people in to hunt it. Since we were just down the road, we got permission to have a look. We went for a decent walk to the old roosts and there was nothing to be found. Then we came back down to the road and spotted lots of birds in a giant redwood. It was a very difficult spot and recovery was a challenge. They were flighty once we started culling so most flew away.
When the birds are under hunting pressure, that's what you get.
