The Last Lot of Autumn Migrants
Starting around six-thirty afforded me to witness two Black kites flapping its wings lazily just to keep afloat upon a weak morning wind, towards the same direction - the north.
Warming up to twenty-eight degree Celsius towards midday had a disruptive effect upon birds' activities, resulting in forming merely small-sized birdwaves not in great number of individual species.
Ordinary species continued to appear until I began the beginning part of Lead Mine Pass, with the widest part of a stream about a score of metres down on my right. Bird calls stopped me to check. A bird was seen perching sideways with a near-upright stance, brown head and mantle with a blue fold-wing, slender and shape of a flycatcher. A first-winter male Blue-and-White flycatcher was my quick response to its identity. Never too quick for observation; it's gone in just a look's time, never found again although I lingered on for quite a moment.
An interesting bird was seen preceding to the flycatcher. It was at the same patch of place that I found a Rufous-faced warbler last winter, but this time it was near the ground.
It was flushed from being hidden on my approach. A bunting that was my first reaction. But when it was located nearby again, it was strictly a warbler - creamy eyebrow stopped far short of bill base or rather vague or dull before eye, quite staight before eye but its aft-part was long and twisted up pointedly at the end, lower earcoverts slightly mottled, bill looking short for being a bit thick, quite dark of upper part but definitely not pale on the lower; no bar on a folded wing, upperbody tending towards brownish tinge rather than green. The length of tail a bit short and not round enough for a bush warbler. Underbody light brown tinge palest in its belly centre. Faint but broad pale streaks were discerned on breast and undertail coverts was rusty-buff (colour description quoting Robson's). To help identification the tarsus were found to be pale, thick and longish for a Phylloscopus). A consultation with Robson's later on ruled out Yellow-streaked, for size and call, the latter rather to be a 'chu, chu, chu, with a very short u-vowel sound, low-pitched. So identification on the spot agreed with later-on reference, a Radde's warbler formerly seen several late-autumn times before.

The call of the Radde's is corrected to weak but clear 'chuk, chuk, chuk' after a visit to Canto-Xeno. (2nd Nov, 2013, Sat)
