Arrivals 
The warm, still, moonlight night evidently tempted 
Flickers 
many birds to press their journey northward, for I added 
no less than seven species to my April list to-day. These 
were the Bobolink, already mentioned, a Least Flycatcher 
chebec -ing in our orchard this morning- and again at evening, 
a single Bank Swallow flying over our meadow, a Thrasher 
in full song on Fairhaven Hill, and at the base of this 
hill or in the pine opposite a Mniotilta 
also singing, two Brown Creepers, and four male Towhees. 
Ruby-crowned Kinglets continue numerous but Yellow-rumped 
and Yellow Palm Warblers are nearly all gone. I saw two 
flocks of Rusty Grackles, one of 14 birds. There was a 
Golden-crested Kinglet in the pines at Conantum and 
another in Miles's swamp. In the big nines opposite 
LW 
Fairhaven Hill I saw a pair of CarolinaSJov/es, a Flicker, 
a Downy Woodpecker, a Robin, and several Yellow-rumps. 
Owl pellets under one of the trees. 
Flickers appeared to be fully up to their normal 
numbers in the country visited to-day. I made the 
following notes relating to the "shout". Ca-ca-ca-, etc., 
a cackle rather than a shout, consisting of from 25 to 
40 repetitions and lasting from 3-g- to 7 seconds. Bird 
sitting on stub just above hole where there was a nest 
last year. Afterwards it drummed on another stub about a 
foot above a new hole from which a female Flicker flew 
as I passed at evening. The drum was a simple roll
