2 Song ID questions, Guangxi, China (1 Viewer)


Well-known member
Both recorded March 2022, Baise Guangxi China. Elevation: 350m.

Recording one (Whistle2): Interested in figuring out the ID of the bird with a short 3-5 note whistle/hoot, singing from higher area of forested mountain area. (song can be heard at 1, 11, 21, 24, 32, and most clearly at 41 seconds)

Recording two (flycatcher 2): Presumed flycatcher? singing from ravine area, perhaps 2-10 ft above the ground in dense area. Song given at intervals of about 8 seconds throughout recording.

Thanks John. Any tips (from anyone) on differentiating Hainan Blue and Hill Blue flycatcher songs? The beginning sequence of fluting notes in my recording sounds really similar to Hill Blue that I listened to on eBird and have heard locally before. At the end of my bird's song almost every time I notice a lower repeated three note "chirp" off sorts, which I didn't really see in the spectrograms of either species. Be curious for any advice.
