I visited on Sunday 27th, not quite the sunny weather I was hoping for, but it didn't rain so can't complain.
Arriving at my usual spot, it was a little while before they showed, both arriving from the west.
Good to see that both were actively hunting, the male often disappearing for long periods hunting elsewhere, but the female hunted and stayed faithful to Parliament.
As I have mentioned before, the Elizabeth Tower is only occasionally used by the Peregrines to hunt from, however on Sunday morning it was used extensively by the female.
I would suspect with the removal of the nearby Luffer Crane at Norman Shaw, which gave them the height for hunts, they have now switched to the next tall structure, the Elizabeth Tower.
During the course of the morning, she launched 7 hunts from the Tower, all ended with failure and all targeting and intercepting Feral Pigeons. There was a fairly large flock just beyond St. Thomas's and 3 times she went for these, once the male joined her as they pair hunted the flock.
I record all birds going over Parliament, there were no other migrants going over to hunt so it seems their attention was set solely on the Feral Pigeons.
A number of Ring-Necked Parakeets also flew past, but these were ignored, they are usually the smaller male's speciality being more agile. Additionally passing Wood Pigeons were ignored, she could take one no doubt, but the heavier pigeon would be a bit of a struggle for her to carry.
I was present for nearly 4 hours, when I left for a look round the Park, she was still hunting from the Elizabeth Tower.
She could also have likely taken a Black Headed Gull given their numbers and density, fairly light and easier to carry. They do take them, but I would suspect as a last resort when hunger really starts to kick in, probably after a good number of failed hunts on Feral Pigeons.
In regard to other birds, 20 species recorded in, or over Victoria Park and the River, Jay and Great Spotted Woodpecker being the stand outs.
