Marston lesserthroat

Still havn’t been able to get any decent photos of this bird but these video stills in better light give a good indication of the colours. The upperparts have no grey tones at-all, looking sandy or warm brown in the sunshine. Brown extends up on the nape. Looks different shades in differing light but always brown toned. Underparts evenly dull, pinkish buff. Bill slender, very slightly hooked at end. Smallish head and long tail adding to the slim appearance. Broken eyering. Have heard the bird tac-ing on a couple of occasions. It moves around very fluidly, no hopping or jumping. Would be great if it dropped a feather.
