A number of people have asked what's happened to my weekly reports (thanks for that) so I thought I had better explain.

My father-in-law has been in hospital for three weeks and I can't stay or even go to Po Toi while he's there. Nothing serious but he's taking a long time to recover.

I hope to go back to Po Toi first week in November.

In the meantime, I'm pleased to read all the Po Toi postings here.

Good record Allen

And the Drongo Cuckoo is by far the longest and latest stayer of all (nine) HK records of this species.


Since Buttonquails are a targets of mine. I spent most of today walking the grass of the south peninsula. In the morning, I flushed a warbler three times in grass on the south peninsula. Each time I flushed it would fly low above the grass for about 8 meters and then drop down into the grass.  I was unable to get photos. The bird seemed slightly larger than a Pallas's Grasshopper Warbler but smaller than an Oriental Reed Warbler. The bird had a dark charcoal-brown head, back, rump and tail. The tail was thick and wedge shaped like a Pallas's Grasshopper Warbler. The underparts appeared sooty buff colored and there did not appear to be any streaking on either the underparts or upperparts.  

I believe the bird was Styan's, Middendorf's or Gray's Grasshopper Warbler. It was not a Pallas's Grasshopper warbler due to the dark rump and upperparts and it was not a Lanceolated Warbler based on the size and lack of streaking on the upperparts and underparts. I suspect it is a Styan's Grasshopper warbler because some photos of Middendorf's show it looking rather warm colored especially on the rump. This bird appeared much darker and cold colored. The bird did not respond to spishing and I didn't hear any calls. I tried for about 20 more minutes to relocate after flushing it a third time and I returned in the afternoon to look but could not relocate it.

In the afternoon I flushed a quail, but unfortunately from my prospective, it was a Japanese Quail and a Pallas's Grasshopper Warbler.

There were two Mugimaki Flycatcher's by the pier and someone mentioned an Black-naped Monarch and Yellow-breasted Bunting were seen.


In the last two outings to Po Toi, I realised that there were few HK residents at Po Toi.  For example, Japanese White-eye seems to be totally absent, and the no. of Bulbuls are very low.  Black-necked Starling, Masked Laughingthrush, Greater Coucal, Great Tit, Great Tit were not recorded and Crested Myna was seen briefly on last Sunday.  The bird density is also very low.  Then I realised that Peregrine Falcon were at the cliff of the South Peninsula, and a Crested Goshawk were around the main area.  I wonder whether these two Raptors were responsible for the departure of the common residents.

I doubted. Peregrine Falcon is good at capturing open country birds but not very good at well vegetated areas. The usual prey items of Crested Goshawk are likely to be lizards, insects and even bats. The "absence" of small birds like JWE is unlikely driven by the raptors.

But their activities should be affected by nearby raptors. The "absence" of birds in a small island should be affected by various factors, e.g. food availability and human activities etc.

I guess they are not really absence, they may just move to another part of the island or hide inside the bush due to the two raptors.  

Just like the birds at TPK. Sometimes they are very easily to be seen but sometimes TPK is dead and silent.

How about moulting? I was told during the moulting period, they are relatively silent.


Although I haven't been seriously birdwatching on Po Toi for several weeks, I doubt there has been any change in the numbers of resident species.

The following species are resident on Po Toi - Pacific Reef Egret, Black Kite, Spotted Dove, Greater and Lesser Coucal, Red-whiskered and Chinese Bulbul, Long-tailed Shrike, Magpie Robin, Blue Whistling Thrush, Masked Laughingthrush, Common Tailorbird, Crested Myna and Large-billed Crow. Peregrine and Sea Eagle are occasional visitors.

Autumn is usually a quiet time for most of these residents, perhaps because of moulting as Captain says.
Japanese White-eye are not resident and are usually absent in September/October. They will come back in November and mostly depart before next summer. Black-necked Starling and Great Tit are also not resident and rare or totally absent. Greater Coucal are quiet at this time of the year.
