To me, watching these Peregrines  is the best free show on earth and today, even though rain was forecast I still went to check  on their  progress and safety.  It's quite striking to see the delicate and good mannered way that Peregrine chicks feed and are fed. I watched one of the youngsters today with a small prey item, a bird of un identified species.  As it fed itself, the other siblings made no attempt to steal it or even take a beak full, just quietly standing aside, preening and investigating their temporary home.  At this age of 28 and  26 days, you can determine the difference,  if not on size then by the noticeable difference in the emerging plumage. The older two have discernibly more "real" feathers, brown and buff, pushing through the down with a speckled appearance on both the breast and back being obvious now. 

The female regurgitates a pellet.

When I first arrived I had heard and then discovered the female sat on the rock face nearby.  She had given herself away by calling now and then. Peregrine calls to my ears are blood curdling screams. I quickly found her in my camera's viewfinder and then watched as she regurgitated a pellet which is something I know they must do but hadn't seen before.  As I sat quietly, the male……that's the tercel……silently came in to the nest ledge with the prey that I mentioned above. I knew that  was going to happen because of the reaction of  the watching female who called almost maniacally, reaching a crescendo as her mate  landed on the ledge.  Hehanded over the kill and  left  just as quickly. 
Later on, after I hadn't seen the female for a while there was a really harsh, almost frightening  scream from somewhere beneath me and close.  The youngsters on the nest immediately reacted, their calls are getting louder and stronger every day and it's now interesting to see that they recognise the calls of their parents and when they hear them they  expect to be fed.
They were right, the female flew  from near me to a spot under the old oak. She was carrying a large prey item and  it seemed as though she could hardly fly  with it.  I suspected that she had gone to pluck it and when she still hadn't delivered it to the ledge I reasoned that she was eating it herself but she wasn't but  It took 15 minutes for the female to deliver it to the very excited youngsters and then  they gorged themselves greedily, fed by the falcon.  It was a magpie yet again, a very popular prey item with the falcon.  She is a Magpie specialist.!  She had removed the tail and wings….and the head of course, this is the usual way of killing the prey.
