Migratory Birds in April

On the 13th of April when I did a survey in Ecology Park, I heard him singing in the thick trees and managed to spot him. A moment later, a Japanese Sparrowhawk flashed by everyone and silence fell...

An Asian Brown Flycatcher (Kosamebitakiコサメビタキ)

On the 28th April I heard him going 'zic zic zzzzzzeeeee....!'

An Eastern Crowned Warbler (Sendai-mushikuiセンダイムシクイ) - only his song

I was lucky to hear them both as they only stop over in and around Chiba-shi for a few hours - few days.
