HK Wetland Park 4 Sep 2018 - first birding day in Sep

Today was my first birding day this month, started with a Thick-billed Warbler trapped and ringed near reedbed (I’m still hoping to get some good hand-free photos of this species).

The adult Amur Paradise Flycatcher arrived yesterday should be gone already, a normal case here, but two new flycatchers, an Asian Brown Flycatcher and a Dark-sided (Siberian) Flycatcher, the latter was an adult which we seldom see in early fall.

Siberian Flycatcher

The two Pale-legged Leaf Warbler were still showing well and calling actively, good for sound recording but not good for a clean shot. And an Arctic Warbler newly arrived at noon, which was even more unphotoable.

Pale-legged Leaf Warbler, confirmed by call

Pale-legged Leaf Warbler - same bird as above, showing a typical shorter primary projection (5 tips beyond tertials) than Sakhalin Leaf Warbler 

recording of the Pale-legged Leaf Warbler above, also very typical higher frequency (reaching 6kHz), as here:

again a comparison from our two recordings

Pale-legged Leaf Warbler - another individual, also confirmed by call

Sooty-headed Bulbul - molting bird

Long-tailed Shrike - nice background but bad perch
