Pied billed Greebes [Pied-billed Grebes](?)

  While in the canoe this morning watching the Prothotary [Prothonotary Warbler],
I heard what I took at first to be a Green Heron. The
sound seemed then to come from the flooded thicket but
when I paddled around this it came obviously from far
up Great Meadow. Although I paddled towards it until
I could go no further it was still in the distance
apparently near "Three Oak Island". It now sounded
very nearly (yet not quite) like the ordinary, prolonged
outcry of the Pied-billed Greebe [Pied-billed Grebe] (the (cuck-cuck-cuck etc
notes) Evidently two birds were making it, one regularly 
answering the other after an interval. I finally set them
down (still with a slight reserve of doubt) as Greebes [Grebes].
Their voices were so loud that Gilbert heard them a mile
away at the cabin. The terminal notes seemed quite normal. 
Saw two Least Sandpipers & one Winter Yellow legs far
up the meadow.
