Rather heavy flight of n.-bound [north-bound] migrants, of species
noted before this. At least 4, & I think as many as 6,
Tennessee Warblers in full song. Heard 2 before
leaving my bed & from 2 to 4 more in run later in
morning. Dexter reports 2 singing near his house.
Many Bay breasts [bay-breasted warblers], also. Heard one close to house in
early morn [morning], another near head of run later, saw 
4 [3 males] [1 female] together in pines near Pulpit Rock, 8 A.M.
Two of them [males] sang exactly like Redstarts. One 
of these two used also the normal song at
intervals. I saw him utter both.
Also in run were at least 4 D.maculosa [Dendroica maculosa], 
2 [Parulas?], 2 Canadian Warblers, several 
Redstarts, 2 or 3 Nashvilles, 4 or 5
Maryland Yellow-throats.
  At 9.30 A.M. Burbank & I saw a red
Screech Owl fly past barn into oak grove
carrying in its bill a flesh-colored hairless
featherless object that looked like a
young Robin. Passing us within 20 ft. [feet] in
blazing sunlight, the bird headed straight
for an abandoned Flicker's hole in an oak
& entered it like a flash of light. I afterwards
saw her head at the entrance. There must
be young inside. The gray Owl could
not be found in the barn then but at
7 P.M. was looking out at hole in 
western end.

just after breakfast. Gilbert [Robert Alexander Gilbert] took him to
Cambridge a little later.
