kestel question

I live in Valencia, Spain and where I walk my dog there is what appears a young kestrel. I've seen s/he hover but mainly perch and glide hunting. This sounds daft but I think this kestrel recognises me. I usually make a repeat whistle when I see them and speak to them softly. Some days of course, they are nowhere to be found. 

The first time I started to think this bird is habituating to me was when it glidedpast me iinto a tree (the one in photos) I was standing close to...but perhaps coindence...

Anyway, I have been in the UK for a few days and today when I walked the dog...no kestrel...not unusual. Bit disappointed I headed home. I am then in a completely different piece of wild land  (campo - 5 minutes walk away) much closer to home/town and out of nowhere the kestrel appears. Flies right towards me and perches on a pylon beside me. I get to get my field glasses out to check, whistle and speak to her/him. They were clearly checking me out, before flying onto another pylon heading back in the direction of their normal fields on edge of village.

So questions:

1. am I delusional or can wild falcons build a 'relationship' with humans? I would swear this bird is acting socially towards me - at a distance of course - but that's twice it's flown directly into my space.

2. when do young kestrels show the change in plummage brown or grey head? This one is brown but is very confident and I'm not sure if there is a gender bias for 'boldness' or if this trait tends to be familial.

3. what is the average hunting range for a kestrel? Do they tend to stay in one area or move?

4. Do kestrels share hunting ground? There is another bird but I think it may be a buzzard in the same area...is this possible? This other bird, seems much more 'grumpy' and less interested in me. 

5. I know with birds of prey in captivity they are put in seclusion for a big moult, how does this work for wild birds? Does it happen over time? I found a lot of primary and secondary feathers. At first I thought it was a predator had caught a falcon/hawk - now I wonder if it was a moult? Can you pass on some links about this?

6. I've attached some photos of the feathers, some of the bird sitting on a tree anda couple of them in flight. Is this a kestrel? Sorry the photos aren't great - only on camera phone at a distance. 

Many thanks for any info for a total novice

  • Further to my above post, today it appears that they are two kestrels. As I walked out I was greeted by the more social of the two as it eyed me from a tree on the path. I then spotted the other on the top of a pylon - appears to be preferred look-out. As I watched the second, she took off and glided on the thermals doing massive loops. Then she was joined by the other and then 'danced' for awhile - with one going into a hover to hunt and the other plummeting like a stone - was truly awe inspiring. Walking past the tree, the social bird had once again taken up position and quite happily preened herself as I watched her, having a bit of a tail wag and fluffing feathers. Great start to day Slight smile
