Classic cachinnans jizz: elongated bird with long legs, parallel bill and sloped head. Bird in active complete moult: most MC and LLC missing, the feathers in these tracts that are still present here probably are 2nd gen feathers replaced in the post-juvenile moult, now skipt and will be replaced later in the process.
