A lifer of a blue flycatcher

Eumyias indigo
Zone F

 What makes my day today is the capture of the blue flycatcher.  It's a lifer for me and for the Kambatik park.  Today is the first time I stumbled upon a blue flycatcher.  I first met it at Zone F and then followed its movement to Zone D about 100 meters away before it disappeared into the surrounding forest.  Is it a  female of the species?  Is it the Indigo Flycatcher ( Eumyias indigo) that is a native to the island of Borneo and therefore Bintulu?  The literature mentions that the Indigo Flycatcher is a resident of the highlands and less frequently seen below 3000 ft above sea level, that is in the lowland dipterocarp hill forest where the park is situated.  At first sight I saw it jumping and hopping on the leaves-covered ground for insects and was not particularly scared of my presence.  Whats striking about the upperside of the bird was the deep blue colour of its crown right down to its back.  In most descriptions the throat and breast is blue but in this specimen it is white.  Does this mean that it is a female of the species?  I have yet to determine this and it is my fervent hope that it will drop by again at the park soon with a mate. to confirm my observation.  Hopefully that day is near.
