Mangrove Blue Flycatcher – song

on 26th March 2022

Post 1.

I saw 3 Mangrove Blue Flycatchers (Cyornis rufigastra rufigastra) at this site; one a pair and another time a single adult female. Images show the adult female.

These birds are easily missed in the shadows of the mangrove forest unless heard singing.

I heard both male and female birds sing. Songs have much variation. The basic structure is described by Wells (2007) as ‘dee dah fee po’, but many more complex and longer songs also give and were heard. Songs are usually given 2-5 seconds apart and have a duration of 1.25-1.75 seconds. I also noted a clicking-like noise to show displeasure.
