We were there this afternoon for the first time, and got some photos of all of the grebes that I can upload later. But in the meantime, here's what was going on there today:
Starting with the first nest we saw walking down from the parking lot, which is the platform near the big rocks along the shoreline- there were two chicks, one quite a bit larger than the other. Both were swimming independently and ranged up to about 10 feet away from the adults. The larger of the two was also doing some diving.
Moving clockwise, we passed the swan's nest and then saw a totally empty nest platform, no sticks or anything else on it. It sounds like that was the platform the swans got to? We didn't see any grebes at all in that area, sadly.
Next was a platform with both adults and five chicks, two of which were swimming on their own for a bit but these guys were all smaller than the big one we saw at the first nest. We could also see at least two eggs still in the nest.
The last platform had a grebe on it and another swimming nearby, but no chicks were visible.
There was also a pair of grebes fishing in the middle of that area, but both were diving so I assume no chicks there.
I have to say, it was very very neat to see so many grebes all in one place!
