Surely this is the bird that was on Po Toi in the spring?
 
But where has it been for the summer? Not on Po Toi, I think. Taiwan?
 
And will it come back next spring?

I think it must be the same bird.
 
I think it's safe to assume it moved off to an area where there are other Ob Pigeons (Hainan perhaps, rather than Taiwan, but that's just based on published range data).
 
 
Species like this seem to simply wander in search of food, rather than having a more fixed "area A to area B and back again to area A" migration route for the whole population. I suspect that individual birds "learn" their own individual patterns of movement, and if they survive, will repeat their movements from one year to the  next.
 
I understood it has found a relatively accessible, visible fruiting tree this time, so hopefully it will be a bit easier to  see this time.
 
I wouldn't be surprised if it wintered on Po Toi now, unless or until the food supply dries up.

Report for first week of October
 
Land Birds
 
I expect surprises on Po Toi but I did not expect to wake up this morning (Thursday) and find almost all the migrants had left overnight. I put it down to very light winds, a clear sky from about 8pm and the fact that most of the birds had been on the island since the weekend and must have been well fed.
 
Fortunately for Graham Talbot’s blood pressure, one of the few birds to remain was the Chestnut-cheeked Starling, so he was able add this to his impressive list today.
 
Even with a poor day today, it has still been the best week of the autumn so far, with nearly 50% more species of migrants than two weeks ago from my records alone, not counting those extra species seen by others. Some highlights were Ashy Minivet, Japanese Paradise and Blue & White Flycatcher, Lanceolated Warbler, Purple-backed (10) and Chestnut-cheeked Starlings, a very early record of Little Bunting (5) and Ashy Drongo. Unfortunately although the birds were good, the photos were not so good – here are a juv Ashy Minivet, juv male Blue & White Flycatcher, Little Bunting and Ashy Drongo.
 

 
The Orange-breasted Green pigeon was not seen again after Monday (to my knowledge). A funeral procession complete with fireworks and gongs which passed directly underneath its tree early on Tuesday morning could not have helped its stability, although it may still be somewhere on the island.  
 
Also seen were 8 migrant species of raptor, Osprey, Black Kite (some migrants), Grey-faced Buzzard (2), Crested Goshawk, Chinese Goshawk (2), Common Buzzard, Kestrel, Hobby (2). Photos are in that order except Black Kite, Crested Goshawk and Kestrel are missing. (The Common Buzzard photo seems to look more like a Harrier but it was definitely a Buzzard).
 

 
It appears that raptor migration is now in progress.
 
Also today, a flock of 7 Large-billed Crows spent some of the morning on the island before migrating SW, which combined with similar records in spring shows that these birds are at least partial migrants.
 

 
Sea Birds
 
No sea birds have been seen since the last tern on 19 September which is a great disappointment. Fortunately, visible migration from the S point has more than made up for this. As well as most of the raptors above, other birds photographed from there passing across the sea into or out of Po Toi were Black-capped Kingfisher and Red Turtle Dove as well as a Stonechat which first appeared at the S point early this morning and probably the same bird later at the top of the tallest tree on the island near the school!
 

 
Waste of Taxpayers Money?
 
It appears that a new jetty is being built on the SE peninsular, presumably for the tourist trade. But I wonder who is paying for it?

Could HK_Twitcher possibly pass the magical 350 mark the punters are wondering?

Second week of October. The same number of migrant species as last week, but not as many birds.  
 
Autumn migration seems to have affected the number of some resident species – I have seen far fewer Bulbuls and Magpie Robins than usual this month, and no White-eyes at all since September. Are they being forced out of their usual territories by the migrants?
 
Visible Migration
 
Early Friday morning I saw 5 flocks of Great Egrets, totally around 150 birds, about 3 miles east of Po Toi heading in a S/SE direction over the sea and directly away from the land. Are they making a direct crossing of the South China Sea, to somewhere in the Philippines? The flight distance of 600 miles would surely be no problem for a fit and well-fed bird, and the wind was light and just behind them. The Grey-faced Buzzards seen migrating last week were on exactly the same course.  
 
Excluding Egrets, I have seen 13 species of migrants either coming into or leaving Po Toi this week, including Black Kite, Kestrel, Japanese Sparrowhawk, Pacific Swift, 3 species each of Pipits and Wagtails, Tree Sparrow and a Yellow-breasted Bunting. Here are some photos of Japanese Sparrowhawk and Pacific Swift leaving Po Toi, and Kestrel and Rock Dove (a regular migrant on Po Toi) arriving on Po Toi.
 


 
Migration may be a successful strategy for a species but it’s fraught with danger for an individual bird. Here, a Hair-crested Drongo attempting an early morning flight from Dangan Island to Po Toi, intercepted in the last 100 yards by a pair of Peregrines.
 

 
Land Birds
 
11 new autumn migrants this week, including Japanese Sparrowhawk, Woodcock, Siberian Rubythroat, Scaly Thrush, Mugimaki Flycatcher, Yellow-breasted Bunting and the highlight, Amur Falcon on Friday. Some photos from the week, Amur Falcon, Besra, Hoopoe and imm male Mugimaki Flycatcher.
 


 
The observant will have noticed the last photo, a freely ranging and handsome chicken which has taken up residence on the gravesites to the south of the football field. This is the only live chicken I have ever seen on Po Toi and, as I guess it arrived by human hand, I will include it in my Po Toi list as Cat E. It is one of the few birds on Po Toi I can safely say is not a migrant.  
 
I got it wrong
 
The new construction on the SE Peninsular I thought was a new jetty has now turned out to be three metal tanks, each of different size. Does anyone know what this could be?
