Alan Wormington posted persuasive interpretations of the red-necked grebe explosion on 7 March as "Red-necked Grebes at Hillman Marsh.' The Marsh is just across the pond from us in Ohio, and Alan adds some observations to the conditions we noticed here in 2003 and 1994. It is interesting to see which species are unaffected by the conditions which affect these grebes. His post can be found at http://birding.aba.org/message.php?mesid=639785&MLID=ON&MLNM=Ontario .
