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? Denis and Maria Poley Richmond, VT
