18/10/10 Hegura-jima, Japan

18/10/10: Clear skies with a North 1 breeze at dawn slowly increasing to N3 by dusk. We witnessed a pre-dawn arrival of Thrushes (with a male Japanese Grey Thrush seen on a track near the toilets) and an early morning northbound movement of 800 Siskins. A Mealy Redpoll was present near the drinking pool though a male Red-flanked Bluetail proved the highlight on the walk back to breakfast. We then again tried unsuccessfully for the Booted Warbler although we saw a Black-browed Reed Warbler there and flushed a Short-eared Owl from the west coast marsh and found a first-winter Mugimaki Flycatcher near the lighthouse and 2 Middendorff’s Grasshopper Warblers at the Antenna Field. Then to Tsukasa Fields where we struck gold finding 2 Pallas’s Reed Buntings and also saw our only Russet Sparrow of the trip as well as a vocal Eastern Yellow Wagtail and 20 Siberian Buff-bellied Pipits that proved our maximum count of the species. On a check of the south a Waxwing trilled from atop one of the piles of rocks and a Kittiwake appeared offshore. Daurian Redstarts proved at their peak with 75 present on the island. We again tried the Observation Platform at dusk where a male Japanese Robin appeared in the drinking pool at 4.55pm – a brilliant end to the day that had delivered two new species for us.

Male Siskin along the Western track


First-winter Amur (White-faced) Wagtail M.a. leucopsis at the Lighthouse



Of the forms of White Wagtail occurring in Japan the pale sides to the head and neck and the absence of a blackish eye-stripe eliminate the possibility of this individual being a first-winter ocularis or lugens. Both first-winter leucopsis and baicalensis are very similar but pointers to this individual to being leucopsis are the small blackish spots on the lesser coverts (and the hint of such on the mantle) and its virtually unmarked malar patches (generally prominent blackish in baicalensis).
