Took a trip to Sandbar his morning. For the most part we observed many of 
the same species reported by Bruce MacPherson yesterday, namely Mallards
(many score), Black ducks, Canada geese, Green-winged teal, Wood ducks 
and red-winged blackbirds (a goodly bunch). There was a subadult Bald eagle 
perched in a dead tree to the south of Rte 2, a single muskrat and a single 
robin.
The highlight of our visit though was presence of numerous Great blue herons
checking out and occupying the rookery.  At first we saw just one flying 
beyond the trees of the rookery's east end, then a second, and then a third.
And then we began counting occupied nests. We are sure there were at least 
10 herons (probably a few more). There were both pairs and single birds on 
the respective nests. All of the occupied nests were on the mainland (east) 
side of the rookery.
Actually we've been wondering, what with the way the nest groups are 
dispersed there, if it should be considered a single rookery or three or more.
Does anybody have the answer, or at least a well-educated opinion?
