Woodpeckers, Woodpeckers and more Woodpeckers. Cranford Park.

Another glorious day today weather-wise, and better than yesterday as there was only the barest of breezes.
Yesterdays outing to the London Wetland Centre was nice, but nothing is more welcoming than being back on the patch. Having coffee and a croissant sitting on a log in the middle of the woods at 8am, with birds singing all around you and greeting the local dog walkers, really is bliss.
It's becoming a routine now to check the nest sites in order. First off was the Great Spotted Woodpecker tree and sure enough the male was checking out his recently excavated hole and then popped in to do some more work. There was no sign of the female this morning, but she did make a grand appearance at lunchtime......more about that later.....
From Mr GSW I went to check on the Stock Doves hollow. Again no sign of either the male nor female, but they could well be inside on eggs.
From there I went to check on the Kestrels tree. The male was sitting high up on the nearby dead tree and took off before I could take a photo. I managed one of him through the treetops, and granted it is a dreadful photo but it shows his distinctive outer tail damage, which is making him so much more recognisable. The female was again, nowhere to be seen. Fingers crossed its because she is now incubating eggs.
From there it was off to see the Wrens. I am really hoping that Tonys sighting of one of the Wrens taking feathers into the nest a couple of days ago, is a good indication. However they are not as easily seen as say our Woodpeckers. Now the nest has been completed, and brambles and ivy are growing around, it's becoming really difficult to spot any of the Wrens. This morning I had a very brief glimpse of one going in the nest hole and leaving after just a minute, but I couldn't get a photo so don't know if there was anything in its beak. But I must remain optimistic, the fact that a Wren is still visiting the nest is encouraging. And if the Wren watch point, another log, was a bit more comfortable I would maybe spend more time there. Note to self: buy a portable cushion.
From the Wrens, is was off to see the Green Woodpeckers nest tree. Two days ago there appeared to be the beginnings of the 'Battle of the Green Birds', as Marmite Parakeets had been seen trying to enlarge the nest hole, but today it took just a few minutes to locate Mr Green a bit further down the  tree trunk, but still keeping an eye on the nest hole itself. There was a lot of calling between the male on the tree and another Woodpecker somewhere behind me. The male also flew over my head a few times, and then flew back to the tree after a few minutes. Is he trying to entice a lovely Mrs Green ?
This part of Cranfood Woods is very busy with Jackdaws, Carrion Crows and Marmites all nesting at the moment. It's certainly not a place to sit if you want peace and quiet. A couple of Marmites were squabbling over a hole in another nearby tree.
With all five nest sites checked (I admit I have given up on the Robin nest that Sue found, its been covered up so quickly by nettles and brambles that its almost impossible to locate), I had a wander around some other areas of the woods looking for insects.

Now that the restoration work at St Dunstans church has finished, the graveyard is again a lovely peaceful place to sit, that's if you can ignore the M4 traffic noises. I used to sit in there a lot last year, and watch the rabbits, and today it didn't take long for a very young one to pop out of the burrow and sunbathe for a while before popping back below again.
As the GSW nest tree is my newest found nest site I decided to pop back there again. I'm still kicking myself that I didn't realise on the 26th February when I was observing the male pulling off bits of bark, that he was going to make a hole there. I had presumed it was too early in the year for excavation work to begin. Now I know better.
The male was on one of the top branches when I arrived and flew to a nearby tree and started probing under the bark for insects. I was happily photographing him when I witnessed something I had never seen before.........
a male Green Woodpecker landed on the same trunk.....
It's highly unlikely this is our own Mr Green, the nest trees are on opposite sides of the woodland.
Mr GSW spotted Mr Green and started edging up the tree.....
Both birds were trying to peer around the trunk at each other.......
Mr GSW edged a bit closer.....
Then Mr Green thought 'sod this' and flew off. Well that's my interpretation anyway. What's more likely to have happened is that Mr GSW was exuding testosterone, and was preparing to do battle for his patch. This happened very very near to his nest tree and the female GSW was very close by. How do I know ? After seeing off Mr Green, Mr GSW then flew high into the branches and mated with Mrs GSW, who I hadn't previously spotted............
Dreadful photos I know, and I had to heavily lighten them. They could have been a bit more obliging and copulated lower down and not behind a branch. But I was thrilled anyway as this is the first time I've seen GSWs mating. It really was a great end to my day.
Elsewhere in the woods I counted seven butterfly species, but only managed to photograph six, the Small Tortoiseshells were deep in the ever growing nettle bed.
I also didn't see any Brimstones today, and nor have I seen any more Red Admirals but I did manage to finally photograph a male Orange-tip in the graveyard.
As I didn't leave the woods and graveyard areas of the park today, there's every chance other butterfly species are emerging around other parts of the site.
