December 1-9
It was generally warm and humid with easterly winds until 6th, with temperatures up to 27⁰C. A cold front associated with the northeast monsoon cause temperatures to fall from 7th, down to a low of 13 ⁰C in the New Territories on 9th.
Good numbers of Asian Stubtails, Rufous-tailed Robins and Pallas’s Leaf Warblers were reported from the last week of November into December.
The Smew remained at San Tin at least until 8th. Two Falcated Ducks were there on 1st.
Mount Davis turned up a Bull-headed Shrike and Radde’s Warbler on 1st but the best find there was a Yellow-streaked Warbler on 8th & 9th. A Radde’s Warbler was also present in the same area as the Yellow-streaked Warbler on both days.
At Po Toi on the 1st, a Chestnut-winged Cuckoo and a Black-naped Oriole were seen (both present from at least 29 Nov); other birds noted on 1st included Ashy Minivet, Radde’s Warbler, Manchurian Bush Warbler, and Rustic, Tristram’s and Black-faced Buntings. The cuckoo and oriole were still present on the island on 6th, along with Red-breasted Flycatcher, Brown-headed Thrush, and Eastern Crowned Warbler, but the best sighting was a Thick-billed Green Pigeon. There are only five previous records of this pigeon in Hong Kong, the last being in 2006. (Note that the ferry on Tuesday and Thursday now returns from Po Toi at 3.30 p.m. instead of 2.00 p.m. – the pigeon was found not long before the ferry departed!)
A Japanese Leaf Warbler was heard calling at Pak Sha O on 2nd; also present were two Radde’s Warblers. (Another possible Japanese Leaf Warbler was seen at Sha Lo Tung on 4th, although this bird did not call.)

December 24-31
The Christmas period proved to be the warmest in thirty years, with the temperature on Boxing Day climbing to a balmy 25 ⁰C. However, the easterly winds were displaced by a replenishment of the northeast monsoon from 28th, and the mercury in the New Territories plunged to 8⁰C in the early morning of 30th (0.9⁰C on Tai Mo Shan!), the coldest day of the winter so far.
Mai Po boardwalk was productive. The two Mallards were seen again on 24th and 29th, and the male Falcated Duck was also present on 29th. An obvious hybrid American x Eurasian Wigeon was present on 29th. Waders included the Nordmann’s Greenshank (at least to 28th), a Long-billed Dowitcher (24th & 29th), and a Far Eastern Curlew among the wintering Eurasian Curlews (28th & 29th). Two adult-winter Pallas’s Gulls were noted on 24th & 26th.
The main reserve was quieter, although the Rook was present at the southern end on 24th, and an interesting hybrid Mallard x Northern Pintail was on the scrape on 25th & 29th ( see http://www.hkbws.org.hk/BBS/viewthread.php?tid=27842 ).
The other main birding site during the period was the forest at Tai Po Kau. A number of scarcer warblers were present, although it took a certain amount of luck and persistence to come across the bird waves they were in. Birds present were a Sulphur-breasted Warbler, two White Spectacled Warblers (a grey-morph and a green-morph), and a Chestnut-crowned Warbler – all of which had been noted earlier in the winter. New on 30th was a Rufous-faced Warbler (c. 10th Hong Kong record if accepted). The supporting cast of Phylloscs included Eastern Crowned Warbler, Goodson’s Leaf Warbler and a fair number of Pallas’s Leaf Warblers.
Other sites that produced interesting birds included Tai Lam CP where a Eurasian Woodcock, a Sulphur-breasted Warbler, five Black Bulbuls and four Tristram’s Buntings were seen on 26th. The Sulphur-breasted Warbler and six Black Bulbuls were present on the following day.
