I was intrigued to see a good number of House Martins landing on the sandy island in front of the hide. They appeared to be collecting mud. It does seem rather late if they are starting new nests, perhaps they are doing running repairs to old nests. It does seem that some arrived very late this year, I would be interested to know if any new nests are being built so late in the season.
Further out a Dabchick was diving and occasionally coming up with what looked like a small fish. It carried this precious morsel towards the reed bed, and just as he arrive one of the young would dash out to be fed.
A little later one of the still stripy young came in front of the hide. It seem incredibly tiny compared to the large Coot chicks around, but it made its way back to the parent birds safely.
All the time a group of up to seven young Yellow Wagtails were chasing around. Every now and again a few would settle for a while to bathe. I saw one dragging weed out of the lake, but I'm pretty sure they won't eat pond weed, perhaps it was finding invertebrates.
At one point one came over to the near side of the scrape, and called a couple of time before continuing the chase with the others.
