Fine
Sunny but hazy. Light southerly wind.
Warmest day of season thus far. Bloodroot
in full bloom. Squills at best. Toads trilling
numerously & merrily. 
  First noted: Bobolink at 4 P.M., flying 
due south very high in air with bursts of
prolongued [prolonged] ecstatic song, thrilling me with
joy & gratitude as I stood listing [listening]. About
the same time 2 Black Ducks flew over
eastward so high that they looked no bigger
than Sparrows.
  Of other birds there were only those noted daily
of late in Robins, Chippins [Chipping Sparrows], Purple Finch, Vesper
Sparrow, Field Sparrow, Phoebee [Phoebe], Pewee, Yellow
rump [Yellow-rumped Warbler] & Yellow Red Poll Warblers [Yellow Redpoll Warblers], Flickers, Meadow
Lark [Meadowlark]. All these sang freely save Robins & Phoebe
both of which remained quite silent. I saw 
3 [male] Robins engaged in one of their characteristic
noisy but passionless squabbles. The [female] again
fluttered at our back windows (in early morn)
but ceased when we closed the blinds. 
  Spent entire day setting out trees, mostly canoe
birches & box elders, from Horsford.

Tent caterpillars out
Ther [Thermometer] Tuesday, May 2, 1916 Wea [Weather] Fine
Rush of incoming Migrants
Clear & very warm with light S.W. [southwest] wind.
Very many birds arrived from the South.
First noted: Brown Thrasher [male] [in full song] (near hen house),
Usnea Warbler [male] [in full song], Blackburnian [Blackburnian Warbler] [male] [in full song] ([?] near house)
Black-thr. Green [Black-throated Green Warbler] [male] (Pulpit R.) [Pulpit Rock], Prairie [Prairie Warbler] [male] [in full song] (full
song heard, once near at hand, Cedar Park. Did not see bird.)
Purple Martin 2 [in full song], Bank Swallow (chatter heard)
Yellow-thr. Vireo[Yellow-throated Vireo] [male] [in full song] (near house). All these
seemed represented by only one or two individuals
each but of Yellow-rumped Warblers there
were at least 50 in one scattered flock comprised
mostly, if not wholly of males. They drifted
back & forth all the forenoon in the apple orchard
& the oaks & hickories behind our barn. With
them were 2 or 3 Yellow Palms [Yellow Palm Warblers]. I failed to
find either species elsewhere about the place.
  Of earlier arriving birds there seemed no
increase save of Tree Swallows, 6 in number.
Our Phoebee [Phoebe] remains [?] silent about
the barn cellar. The nest there had 3 eggs today.
  Early this morning the [female] Robin was fluttering
as persistently as ever, but at another lower
back window that of our back entry. When
we hung a canvas over it outside she desisted.
She resumed building yesterday on step ladder in
shed until we hung it up again.
  Spent most of day near house setting out plants.
Walked to Birch Field with Tim at morn [morning] & late P.M.
