After the lull in migratory bird movement that is June and July – a period that I just about get through with gritted teeth – August brings more hope. The species that I target are Yellow Wagtail, Spotted Flycatcher and Tree Pipit. None are guaranteed in urban Oxford, but most years see one or two records of some of these species. Passerine migration kicked in early in the Lye Valley this year, with small numbers of juvenile Willow Warblers and the first Lesser Whitethroat of the year all being recorded in the first week of August. The first of the scarce August trio fell on 9th August, when a Yellow Wagtail flew over Warneford Meadow, calling loudly. There was then another quiet period, although large roving flocks of Tits, Chiffchaffs, Blackcaps and Willow Warblers kept up interest. Almost as soon as we entered the second half of August, I struck patch gold. A chunky-looking brown finch was flushed by a dog walker on Warneford Meadow. The movement and the call instantly attracted attention: a hard “tic, tic, tic“, a call like nothing else I had heard on the meadow in over 500 visits. Fortunately the bird perched for a few seconds on a distant oak:
A Corn Bunting! Almost as soon as I said the words, it took off and flew strongly south, over the golf course and away:
Although Corn Bunting now breed quite close to the city, records from within the ring road are exceptionally rare. There are no Oxford city records of Corn Bunting on the OOS database or on eBird. Asking around within the local birding community revealed that the last confirmed record of Corn Bunting in Oxford city was a breeding record in 1980, some 43 years ago! (Bayliss (1982) per Ben Sheldon). Ian Lewington commented that this looks like a juvenile bird, perhaps engaging post-breeding dispersal. Many thanks to Ian and Ben for their input.
My adrenaline levels had only just recovered, when two days later, on Saturday 19th August, I heard a loud clear flight call, the classic high-pitched, buzzy “tzeep“, from a migrating Tree Pipit. Looking up revealed two pipits flying south-west, not that high above trees of Warneford Meadow. I used to try to photograph flyover migrants, but in many ways a recording of the flight call is more definitive evidence of the identification. The challenge of recording Tree Pipits is that they go over quickly and don’t call constantly. As soon as I heard the first flight call, I hit record on my phone, but by the time the birds called again they were too distant for my phone to pick up the call clearly.
Nevertheless, I was stoked, the second of the August trio had fallen and this was the earliest Tree Pipit I have recorded here by two days, plus the first record of more than one bird. Overall, this is the seventh Tree Pipit record at this site over the last four years, some details of the other records are here. Now for Spotted Flycatcher to complete the set!
