Late occurrence of Ruby crown Kinglet [Ruby-crowned Kinglet]

written and about sunset I heard the sharp chirp of the
Orange-crowned Warbler repeated several times and looking out through
my study window saw the bird within ten feet of it in a Japanese
barberry bush. Here he remained for several minutes in company
with a female Ruby-crowned Kinglet. The two birds appeared
curiously alike in general coloring and also in behaviour but the
Orange-crown lacked, of course, the light eye ring and wing bars of the
Kinglet and was fully one-third larger while unlike the Kinglet
it did not incessantly quiver its wings.
  The Garden literally swarmed with birds to-day, especially in
the afternoon. Besides the Warbler and the Ruby-crown I
noted a Golden Crested Kinglet, a Brown Creeper, a White bellied
Nuthatch (male), 2 Chickadees, 2 Blue Jays, a Goldfinch, 6 Fox
Sparrows, 4 or 5 Juncos, a dozen or more House Sparrows,
and several Crows (on wing) - in all twelve species.
