The last photo shows a first-winter male Red Turtle Dove, showing a mixture of juvenile and adult male plumage.
I was also on Lamma (southern Lamma) earlier this week - although there weren't many migrants, I did see:
Forest Wagtail x1
Arctic Warbler x10
Black-winged Cuckoo-shrike x1
Dusky Warbler x1
Bright-capped Cisticola x1
