Middendorff’s Grasshopper-warbler Locustella ochotensis ochotensis

on 15th September 2019

“A tough Locustella Warbler (Locustella ochotensis ochotensis), commonly known as Middendorff’s Grasshopper-warbler, it is hard to see and uncommon even in Hokkaidō.

“Can look quite variable in different posture and lighting – all images are of the same bird.

The image below shows the warmer uppertail-coverts and rump, as well as the sub-terminal black spots and white tips of the tail. Kennerley et al 2010 suggest that L. o. ochotensis are warmer and have diffuse mantel streaking than the northern subspecies.
