Asian Brown Flycatcher – conflict behaviour

posted in: birds, Intraspecific, Vocalisation | 0

I saw three of these migrant Asian Brown Flycatchers (Muscicapa dauurica dauurica) in conflict in the early morning. I first heard the birds making loud calls; sonogram and waveform (above) and a recording of the calls is located here:

They were located 3-5 meters apart on high trees. Intermittently one would chase the other off the perch. They exhibited aggressive physical conflict with beaking (above, below). Images were difficult as the flight conflict was erratic. The conflict I observed lasted from 7.30-7.50am and continued even after I moved on. Wells (2007) notes that “freshly arrived stagers and winterers interact aggressively, with much chasing and vocalising until they settle into exclusive spaces ..”.
