Can you imagine figuring out which nests are in which tree - and then accurately counting them?
That is why groups of 3 or 4 sets of eyes!
To the right is a nest that has fallen, or blown, down. Those are noted.
A lot of looking up, but good to look down some too. Here is a pretty mushroom and a "blowdown" partially made with a long strand of wire!
And on the way back down too - very slippery, steep footing!
THANKS Everybody - hundreds of nests counted.
