觀察時間: 二零一五年三月二十八日上午六時五十五分至十二時半左右。筆者與Matthew Kwan在前一天的黃昏先乘直通巴(HK$70)到南澳過夜，早上再乘車(15 分鐘左右RMB$50)到七娘山 (即大鵬半島地質公園) 觀鳥。今次取道在西邊山坡的小徑，全程步行垂直高度約700米。小徑是”直上直落型”沿山脊通住山頂的小徑，路經稀疏樹林部分，及覆蓋不到西邊山坡的一成面績。開始時天色還可，上到650米高時有些霧: 山頂能見度只有20米左右。本調查共紀錄41 種鳥。過往鳥類調查可見莊馨等人的2013年報告 (tropical geography, vol 33 no 5, p582-587)。跟這篇報告為基礎，本調查增添18個鳥種，合共79種鳥。

七娘山西邊山坡估計為有三四十年歷史的次生林，低地為草地/高灌木林。山谷有些地方樹林較大及茂盛，可惜沒有小徑可達。整體而言，七娘山鳥况尚可，主要集中在山上300-650米高的次生林上。優勢種為兩種山椒鳥、白頭鵯，高雞冠、栗耳短腳鵯，相思及太陽鳥。本調查亦紀錄到金頭縫葉鶯，白喉短翅鶇及小鳞胸鹪鶥等林層底棲鳥，證明七娘山西邊山坡林層下部良好。強腳柳鶯亦十分普遍。另看到小量紅咀相思，初步認為這鳥在這一帶廣東的次生林廣泛分佈。相信若有沿等高線小徑通往西邊山坡中部的茂盛樹林，或會看到更多鳥。

28 Mar 2015

-        Time: 0655 – 1230h

-        Western slope trail, near the museum, the total distance (return the same trail) is about 4 km. Each way is about 2 km.

-        Altitude : The starting pt is about 50 m and the hill top (the great platform only) is about 780 m. The trail is very steep

-        Coverage = the trail probably covers 5-10% of the western slope. Poor visibility due to the trail is along on the uphill ridge. Both Matthew and I believed that the trail does not touch the prime woodland area. The visibility was further down when we reached the hilltop area due to the mist.

-        The lowland part (below 200 m) is tall shrubland and grassland mix, probably around 20 years. The majority of the woodland is young secondary forest, probably 30 to 40 years. Some large trees (trunk diameter 400 mm) were seen above 600 m, but the woodland was progressive replaced by large shrubs around the hilltop areas. Large trees in ravines were seen from distance. Gordonia axillaris appears to be dominant at the secondary forest in the higher altitude. Some individuals of this “shrub” species were about 8 m high. Most trees along the trail were around 6 to 8 m high. The diversity of trees appeared to be diverse, e.g. different trees and not just dominated by Machilus. The understorey in some areas appeared to be dense and diverse.

-        Like similar woodlands in this part of Guangdong, Minviets, Chestnut Bulbuls, Red-whiskered Bulbuls, Chinese Bulbuls, Japanese White-eye and Fork-tailed Sunbird the dominant bird species (i.e. frequently encountered).

-        The presence of Mountain Tailorbird, Pygmy Wren Babbler and Lesser Shortwing indicates that the understorey of the woodland is well established. These three birds are considered to be resident understorey birds in Hong Kong.

-        Brownish-flanked Warblers were surprisingly common here. This may further indicate that the understorey of this woodland is good enough to attract ground dwelling birds.

-        A small number of Pekin Robins was observed in the present survey. Although the abundance is not great and fewer than those at Yinpingshan, it appears that this bird species is widespread in young secondary woodlands around this part of Guangdong.

Logistics
-        Took a direct bus from Kowloon Tong to Nanao: one way HK$70, about 2 hrs. The return one is RMB$70
-        Stayed overnight at Nanao. Hotels can be found along the seaside. A twin room ranged from RMB$160-200.
-        Took arranged car to the geopark entrance. One way RMB$50 (around 15 mins, a bit rip off). The return one cost RMB$40.
-        Go earlier! This geopark trail is a very popular one. When we went uphill in the early morning, only 5 people were seen (including two wardens), but when downhill at about 11:00, the trail was full of people.

The way forward
-        Will try a night survey as Collared Pygmy Owlet has been recorded
-        The eastern trail will be tried later this year.
