Heron 
Near the north end of D a vis's Hill we came suddenly 
on a Green HeronI He was perched on the branch of an 
oak over the river and we looked at him for several minutes 
through our glasses at a distance of not over 30 yards, 
making absolutely sure of the identification. If I am 
not mistaken, I have never before seen a Green Heron in 
Massachusetts before May. 
We continued our walk across the Mason field to 
Lawrence's woods, where a Red-shouldered Hawk was screaming, 
and down to the edge of the meadow where our appearance 
started up a pair of Black Ducks and the solitary Goose 
which has lingered hereabouts so long. It is remarkable 
that he did not join the flock that passed over early this 
morning for he must have both seen and heard them. He 
honked vociferously as he rose and flew off down river. 
Returning, we heard a Solitary Vireo in full song 
in some dense young white pines near the Mason field. 
During this walk we noted three drumming Partridges, one 
on the Blakeman ridge, one at the northern end of Davis's 
Swamp, the third in Lawrence's woods. 
Faxon left for home by the 4.15 train. I took 
supper alone in the cabin and started for Concord some 
time after sunset. The Bittern was pumping and a few 
Robins, Red-wings, Song Sparrows, Swamp Sparrows, and Grass 
Finches singing, but none of them with much vigor or 
steadine ss.
