patch Tree Pipit and a few oddments

came across this Tree Pipit yesterday oddly in light south-westerlies; I only get Tree Pipit on my patch about once in four or five years so this was a notable bird -- first noted when it flew out of the back of a bush and gave the very quiet psee call that I associate more with Olive-backed! it then dropped into some rank grass and failed to show for 15 minutes -- when I flushed it agin it gave a slightly more TP like call but still not loud -- views though confirmed it was not a patch mega just a real goody;
