2007 was the year of the caterpillars!!! About 3 bad years as the invasion
proceeded north. Now that the caterpillar has reached its northern limit
for winter survival is it possible we are now seeing the fallout of the
cuckoo's that were following the bug invasion? Will the Cuckoo return in
numbers next year if they did not find the big caterpillar numbers this year
and spread out looking for the next outbreak of the worms? Only time will
tell. As for my earlier inquiry about the Canada Goose re-nesting after
the early spring flooding, no indication here in Danby. All the young geese
were the same size at the same time so no late hatchlings noted. Nancy
