Comments:
Galinate is observer for 2006. Unknown observs for other years. These are historical records from 1998 to 2006 except for 2002 included in the Atlas. Only year is given for 2006, no specific dates. Different grebes counted on different survey dates in same year are treated as seperate and I did not combine them for that year.
