I shall call this type of WS the "SWS", as it is relatively soft. The "Whirrrrrr" is much softer than the "Wheeeoooo" of the ordinary LWS, to which it is probably closely related; and even the preliminary, "duh"s are probably softer than those of the LWS.  The SWS may well be very low intensity and/or greatly inhibited version of the LWS. In this connection, I should mention that what appear to by very low intensity ordinary LWS's the initial LWS's long before sunrise, also include only 2 preliminary notes, comme ca:  [[two short lines followed by one longer line]]

[[underlined]] Saltator [[/underlined]] I. December 24,1958 Iquitos

The [[male symbol♂]] gray Saltator that I have been watching for a few days seems to have another type of LWS in addition to the one I have described before "Duh Wheeeeoooo Wheeeeoooo duh duh wheeoo" comme ca: [[dash,two long upslanting curves, two dashes, wavering line]]
Given by [[male symbol♂]] separated from [[female symbol♀]], in usual sitting posture, bill OCB with notes, frequently associated with "ordinary" LWS. The [[male symbol♂]] also gave a few brief phrases intermediate between this "special" LWS and the ordinary type; and the most common variation of this special type itself was the omission of the last note.  I think that the unmated [[male symbol♂]] I watched last week also gave "special" LWS's of this type.  This [[male symbol♂]]'s "singing posture" is [[underlined]] quite [[underlined]] long-necked. Neck feathers quite ruffled during the notes. Lower body feathers somewhat fluffed
