Duet Song of Indigo Flycatchers
On January 28th- February 04th 2017 about one week I had birding in Raden Soeryo GP Forestry. There are a few birding site of area that I have visited as hot spring "Cangar", Watu Ondo Bridge, Gajah Mungkur, and Sendi.
Many birds is interesting and beautiful that I can see on these premises, especially in the hot spring “Cangar” and Watu Ondo Bridge. If compared to other places I have ever visited before, the birds in Raden Soeryo GP Forestry much more easily are found and approachable.
While I was drinking and eating fried foods, the birds will come by it selves around the stall near the hot spring. Javan Flameback Chrysocolaptes strictus, Grey-headed Canary Flycatcher Culicicapa ceylonensis, White-crowned Forktail Enicurus leschenaulti, Little Pied Flycatcher Ficedula westermanni, Indigo Flycatcher Eumyas indigo and other birds, often small insect foraging on trees near stall.
However, from all of the birds, Indigo Flycatcher (Eumyas indigo indigo) is one bird that caught my attention. When I was eating “Sempol” (typical food of this place) in the edge of the road bridge Watu Ondo, four individuals of Indigo Flycatcher approached me.
Two birds were perched close together on Casuarina junghuhniana. The distance of approximately two meters away from where I was standing, it was very obvious and very beautiful. And the shiny metallic blue when exposed to sunlight.
The two birds were chirping softly, a very beautiful done repeatedly. When one individual chirp, other individuals will replay with a chirp while slightly bowed head. This behavior have observed about five minutes, before the birds fly away.
The two birds possibility male and female which will perform the courtship display of it preliminary breeding cycle. It is based on breeding information of Indigo Flycatcher that known on February-August and December.
Indigo Flycatcher found only in Montane and submontane primary and moss forests, from 900 m to 3000 m; generally less frequent above 2600 m. of Java island, Indonesia.Beautiful moment I have rarely encountered before. A perfect birding and delicious food!
