In any case, the 2003 survey indicated that subpopulations are fragmented, with probably no more than about 100 pairs occurring in any one area. It is not known how much the grebes move about until establishing breeding territories, but presumably, the species is fairly sedentary due to its flightlessness.
A 2003 survey revealed that grebe subpopulations are fragmented, with only a few hundred pairs potentially found in any given area. The extent of their movement before establishing breeding grounds remains unknown, but their lack of flight suggests they are likely sedentary.
