Dipped YBW but Parakeet seen

On Monday 21st September, I went to Gunton ORT to follow up a report of 2 YBW's yesterday, saw Rob Wil but we both missed the YBW (by minutes typical!) both James's had along the northern hedge of Dip Farm, as we were looking a female Sparrowhawk flushed an unfortunate Greenfinch out of the bushes both (the Greenfinch and the pursuing Hawk) flew south over the playing field with the Finch jinking to elude the Hawk 5X, but the superior aerial ability of the hawk proved decisive and she snatched the poor Finch in its talons and then flew back north. Andrew E joined us, despite checking several Tit flocks (mostly LT Tits) still no sign of the YBW. As I walked back, I heard the screech of a Parakeet, and a female Ring- necked Parakeet flew in at 6.20pm and perched in the sycamore, eating the sycamore seeds just along the NW edge of the Dip Farm playing field in the hedge bordering Gunton ORT, it then flew over the other side of the track to an Oak for a few minutes before flying off after 10 minutes later, I later heard it at 6.37pm by the Gunton ORT (slightly further north) but failed to relocate it.
