spread tail and tremulous wings giving a note 
like tr-r-r-r-r on a descending scale. Heard 
a harsh weak note coming from the mardr. One 
of the killdeer ran through the grass in the 
direction of the sound. I marked the place 
and approached. I could see nothing for a time 
hut suddenly I saw a young one in plain sight 
on the mud. The crown and hack was greyish 
hrown; line around crown hlack; line around neck 
and another on the color line between the hack 
and the belly hlack; tip of wing white; lores 
white; underparts white. It could not stand 
upright; its legs were so weak. Found 3 others. 
The father fed them while the other tried to 
attract my attention. Then I went home. 
May 22, 1899 - Monday . 
T.'ent down in the fields after school. 
Heard a vesper sparrow give an alarmnote like 
tseep. It was sharp and rather mettallic. Saw 
some song sparrows. They were much agitated and 
gave another mettalic note in connection with 
its chimp, like tsit chimp . Noticed that in 
some meadowlarks the song is longer and more 
varied than others. Then I went home. 
May 25, 1899 - Tuesday . 
This afternoon at recess I went down by 
the ditch. Saw a male Maryland yellowthroat. 
Its flight was hobby like a Chicadees. It would 
dive into the weeds and suddenly appear a few 
feet farther on. It would flirt its tail and 
give its alarm-note in the time it remained in 
sight. When it sang its wings and tail tremble 
and the body shakes. 
Saw a female rosebreasted grosbeak gather¬ 
ing material for a nest. It lit on a weedstem 
and then reached out and bit off a small one. 
She did this until she had 4 or 5 in her bill. 
Each time she made a chewing motion with her 
hill to make room for the next one.
