Like all hummers, it is almost fearless in contact with human beings
and yesterday, as I was inserting a bath dish into the cage, flew
up to it and bathed while I was holding it.
A blossoming spray of Kuphea is kept in the cage in order
to encourage it to attempt hovering flight.
Color pictures
of hummer. Colored motion pictures of this hummer were taken Nov.22nd,
but they do not show well the exquisite variation of color
as seen at various angles of illumination, of the gorget and crown.
These metallic hues appear to be so actinically potent that over-
exposure results when the stop is set for correct exposure of the
rest of the bird. The result so far is that the metallic colors
appear washed out. (Jan 20. Now thin prolonged light
from surface is probably cause of this)
Rhody not having appeared either here or at his post on the
west lot by 1 P.M., I went down into the thicket toward his house
No.2 looking for him. He saw me first, for when first seen he was
rapidly threading his way through the underbrush to join me. He
followed to the tool-house without delay.
I am giving him the young mice, about one-third grown, now
in order to preserve adult breeding stock. Usually he has been con-
tent to eat but one of these--so I have thought--but, this time I
placed two in front of him and he promptly gobbled them in quick suc-
cession, still kicking., and kept his place. So I handed him another
and he ate that too. When offered a fourth, he looked at it "calcula-
tingly" but turned away.
He again slept in No.1.
December 5th
Mild weather continued.
Rhody did not come up to the house today and was not seen at
any of his accustomed haunts until about 3 P.M., when Julio gave
him a mouse as he was about to retire for the day in house No.1.
December 6th. (Sunrise 7:10; sunset 4:50). With the approach of the
Winter Solstice the times of sunrise and sunset are changing slowly.
A little thrasher full song during the forenoon. Neo, on
invitation, appeared for worms.
Rhody was not seen during the forenoon. At 1:30 P.M. I went
down into the brush of the west lot without seeing him, but he must
have seen me for, on my way back, a glance to the rear revealed him
using both wings and feet to overtake me. When we got to the tool-
house I offered him two small mice; as he had shown such eagerness it
seemed reasonable to assume that his appetite would be commensurate.
However, he wanted only one, although he watched the second one for
a minute or two as if having designs upon it. But in the end he ran
off suddenly as if resolved to put temptation behind him definitely.
As I drove by his No.1 house at 2:45 he was already in it.
Julio gave him another little mouse there an hour or so later.
The fact that he, at present, is often not coming up to the
house for a mouse until I go down there and invite him, suggests
that his food requirement is now so small that the hunger stimulus
is not sufficiently powerful to cause him to seek food here on his
own initiative; but when he sees me going through my leading-the-way-
to-the tool-house "pattern" he "suddenly remembers" that he has not
had a mouse. (A psychologist could, doubtless, phrase this observa-
ton with much greater precision).
