Habitat:
|
First seen feeding about 20 feet high in live
oaks, later in ragweed below 6 feet. |
Behavior
of bird: |
James first spotted a Bell’s Vireo feeding in a
live oak and alerted me. The bird was foraging on the tips of branches. It
flew a tree or two over, which is where I got my first look. As I was
watching, it moved down a branch and got to within a foot of a second Bell’s.
The birds were on a linear route to the west, and dropped down into a ragweed
field near the edge of a small grove of short live oaks. We approached and
found them foraging together in the ragweed, moving deliberately within the
thick leaves. The birds then entered the trees and moved west. We got a few
more looks, then lost them and abandoned the search, as rain had gotten
heavy. The birds displayed typical Bell’s behavior, with
nervous flicking and fluttering as they fed, somewhat gnatcatcher-like. They
also froze at times and simply looked slowly around. |
Description: |
Typical eastern-looking Bell’s Vireos, both very
similar to one another. The following description applies to both
individuals: Small greenish and yellowish passerine, warbler-sized,
but told as a vireo by the thick bill. A soft olive-greenish on mantle, with a grayer
cast on the crown. Whitish ground
color below, with yellowish wash slightly tinged greenish on flanks. Slight diffuse
pale area, basically diffuse pale eye crescents around eyes, pale loral
spots, but without a defined spectacle. Only one pronounced whitish wingbar,
that of greater coverts. Bill pale horn with dusky culmen. Eyes dark. Legs
bluish gray. |
Voice: |
Not heard. |
Similar species: |
Among vireos with wingbars, White-eyed most
similar. Written descriptions cn be inadequate to separate the two, but
perusal of the photos should eliminate White-eyed. |

Previous experience with
this species: |
Seen pretty regularly. These birds were my 4th
and 5th of the year. I’ve seen many in LA and more out of state. |
