Dying Emerald Dove, Common Fauns

To Fa Peng area - which I've found the most productive for woodland birds on Cheung Chau - and a sad find: a dying Emerald Dove, which someone had placed in a broken polystyrene box by the path.
A beautiful bird, but had damaged wing, and when it rolled over, I could see that a chunk of its left side had been ripped out - maybe by a cat, maybe by a predator like a Crested Goshawk (a guess: maybe a goshawk had caught it, and was starting to eat but was disturbed by people passing by).

Might be one of the two Emerald Doves I saw very close by on 3 March.
I carried it a short way, heading for the SPCA, but then noticed the chunk missing from its side: no hope. Put it down, and was glad to see it die (otherwise a lingering death; I hadn't been up to snuffing out its life).

More happily, I heard what was  almost certainly a Pale-legged Leaf-Warbler: a migrant, that lurks low in woods, and which I chiefly find by the call - rather like a squeaky bicycle wheel. Rather early for this species.

Down Fa Peng Vally, a party of four or five Blue Magpies close to the path. I lived on Cheung Chau a few years before first finding this species here; now find them regularly, and they maybe breed (or come over from nearby Lantau?).

I believe that - like Koel and Great Tit - Blue Magpies have colonised as woodland cover has increased, with transition from scrub/grassland to secondary woodland in several parts of Cheung Chau. They're among the most exotic looking birds in Hong Kong: dull blue above, with black on heads, bright red bills, and very long tails with white bands on undertail. Can call loudly, especially whistles and rattling, tho a variety of calls. Fond of hanging around in small parties, as I saw today.

Also low in Fa Peng valley, heard a Grey-headed Flycatcher - seen/heard one in this area several times this winter, so think this is an over-wiintering individual; it should migrate north v soon. A boring name, but a handsome bird - body yellow, head indeed grey, upperparts greenish, very active.

Common Faun butterflies were much in evidence, along paths in a few places in woods. Maybe only just emerged (from chrysalises?). This is one of Hong Kong's commonest butterfly species. More attractive in flight, when mostly dark brown, offset by paler faun at wingtips.
