Second- 
heavy 
migration 
this 
month 
Ardea 
herodias 
spent the day together most pleasantly, taking a long walk 
"before dinner through Davis' s Swamp and "beyond nearly to 
Lawrence’s woods. Spelman left for home about 4.40 and I 
sailed slowly back across the meadows and up river to the 
Buttricks* an hour later. 
The shore of Ball’s Hill and the woods, swamps and 
thickets everywhere we went during our walk this forenoon 
were simply swarming with birds. Evidently a rush of migrant 
arrived early this morning although last night was cloudy 
with a chill north-east wind. The majority of these birds 
were Cat Birds, Bla.ck-throated Green and Chestnut-sided 
Warblers, Rose-breasted Grosbeaks, Water Thrushes and Oven 
Birds. The only additiors to my list were_ two Parula W a rblers 
and “Save Gwallows (heard). A few female Yellow-rumps still 
linger and we saw. one White-throated Sparrow.] 
As I was crossing the meadows at about 5 P. H,, I 
stood in towards the south shore in hopes of seeing the 
Bittern which I heard pumping there,when I suddenly spied 
three Great Blue Herons standing erect near the water’s 
edge. They permitted me to sail past within 50 or 60 yards, 
looking at me suspiciously by turns and then fixing their 
attention on the water at their feet. Through my glass I 
could see the color of their eyes and every marking. Two 
were old birds in perfect plumage with long occipital plumes. 
The third was a gray bird with a blackish crown. They were 
wonderfully graceful, dignified creatures.
