In Blyth's Reed it should at least be equal since this species almost always has a more heavy bill than Marsh.The shape of the head is not sloping in this bird as it is in most Acro, giving even more a snouty impression. Not always, but we have more than one photo here which shows only this 'peaky' headshape which is common to Booted,The body is not lengthy either and the headpattern is very good for Booted.Which I think it is.Here the measurements for some speciesThe  number is for the bill in mm : tip to skull.Blyths Reed: 17.2-18Marsh       : 14.7-17.1Padyfield   : 14.8-15.2Booted      : 13.9-14.1Sykes       : 13.9-14.1Eastern Olivacious: 18.0-19.0</blockquote>
