The relatively large number of Tiger Shrikes was a surprise. I was delighted to actually see the first of them after hearing it in dense cover in the middle of the island. Later I heard a second towards the north end but only got a glimpse as it dived into cover. About 100 metres on I came across two more together but I couldn't tell if one of them had been the bird I'd just seen. These two birds offered better views and I was finally able to get a shot of one of them.

Manchurian Bush Warbler isn't a rare bird in Japan (it winters in the extreme south of the country) but it's a scarce enough migrant to be noteworthy. I first heard one while walking along the coastal path but it was too far off to have any hope of seeing. Then later, again at the south end of the island, a more obliging bird was singing beside the centre path, another a little further into the thickets was responding to it's song.

It's interesting to compare those images with another borealis (same song) I saw on Yonaguni a few years ago on April 8th. The Yonaguni bird looks far warmer in colouration, perhaps two months could account for that difference, but also looks much heftier with a more powerful bill. Though there's significant difference in size between male and female both of these birds were in full song and so ought to be of comparable size I'd have thought. Incidentally I've only ever once heard cantaurians song, a bird on Mishima a few years ago that was impossible to see in dense secondary growth.
