Walked around the Ministry of Public Relations early morning and was rewarded with a reasonable number of migrants including a 1cy Asian Paradise Flycatcher of the migrant race incei, which is rather surprisingly the first one I have seen this autumn. Others migrants included at least three Yellow-browed Warblers, one Arctic Warbler, one Taiga Flycatcher, a Brown Shrike (heard only), and a Black-naped Oriole.
I also saw a couple of Asian Brown Flycatchers, one of which confused me because it was giving a high-pitched, drawn out single note contact call that I had not heard before. I checked the call against a MP3 of what Xeno-Canto has down as a Dark-sided Flycatcher. The call my bird was giving and the MP3 were almost inseparable, so this contact call would not be very useful for separating these two species in the field (a quick check of X-C shows that it has a couple of examples of ABF giving this contact call).
