Can't you get any more in your mouth?

We saw these Swallows today, making the most of a fresh patch of mud, from yesterdays downpour. Could he not manage to get any more in!! Not sure if this means they are still nest building, making extra nests, or repairing those made earlier! They were so cute doing a couple of fly-overs 1st to see if it was safe to swoop down, they didn't stop long. Look Larger for more detail
Quiet day today, I was a bit poorly and had to go to out of hours Dr, but should be on the mend in a couple of days, I missed my swim today though ;0(
