Ther [Thermometer] Monday, Mar. 19, 1917 [March 19, 1917] Wea [Weather]
15 [degrees] min [minimum] 21 [degrees] max. [maximum] Shrike. Fine
  Wintry weather back again; brilliantly
clear with high N.W. [northwest] wind. Ground 
hard-frozen, snow melting only a little
where fully exposed to sun's rays.
  Garden birds: Jay & Crows heard.
A Northern Shrike alighted in seckle pear [seckel pear]
tree about 5 P.M., remained there perhaps
three minutes, flew thence to cherry tree, left
that a few seconds later to be seen no more.
Batchelder [Charles Foster Batchelder] & I watched him from my study
window. He looked exactly like the
remarkably handsome one that visited the
Garden on January 22 last & probably
was that self-same bird. On that occasion
he sang freely. Today he uttered no sound
that we heard.
  Devoted forenoon to picking out surplus
skins of Heath hens, Pinnated [Pinnated Grouse] &
Sharp-tail Grouse [Sharp-tailed Grouse] which Gilbert [Robert A. Gilbert] took to
Mus. Comp. Zool. [Museum of Comparative Zoology]. Batchelder called
at 4 P.M. staying until 5.30.
  Nuttall Club meeting this evening.
Dr. Phillips gave us a most interesting 
talk on Mendelian laws illustrating it
with numerous skins of hybrid Ducks & Pheasants.

Shrike singing.
Ther [Thermometer] Tuesday, Mar. 20, 1917 [March 20, 1917] Wea [Weather]
40 [degrees] max. [maximum] Robin & Grackle arrive. Fair
Mostly sunny; calm; mild but chilly.
  Garden birds. A Shrike singing in
catalapa [catalpa] tree by Museum; a Robin calling
just before sunset; a Crow Blackbird's husky
voice heard in mid P.M.; half a dozen or
more scattered House Sparrows.
  The Shrike here yesterday was doubtless the
self-same bird observed today. On both
occasions he looked smaller & darker colored
above than a Northern Shrike & seemed to have
a broader, blacker head stripe. Nevertheless it
did not occur to me that he could be anything
but a Butcher bird until I heard him singing
this afternoon when he uttered only a clu-e
note given thrice in slow succession & thus
repeated many times at short intervals.
This song, together with the bird's small size
& peculiar coloring, leads me to think that the
bird must have been a Migrant Shrike. So
also, may have been the one noted on
Jan'y 22 [January 22, 1917] but that seems less likely.
  Spent day in Museum picking out 
duplicate birds to send Mus. C.Z. [Museum of Comparative Zoology]
A.M. Frazer spent a long evening (7.30-11.30)
with me. We talked over old times &
present ones, also. I enjoyed it hugely.
