Red-winged Blackbird juvenile/female?
Juvenile plumage : in both males and females, juvenile plumage is similar in color and pattern to that of the adult female, except for the yellow coloration of the lower body and the sides of the head . The shoulder spots appear mottled and are brown and yellow or brown and beige.

The female is described as more brown above with less beige below and a closely veined chin.

Females are dark above with feathers bordered with beige or rust. The lower part shows black and white streaks, but with more beige on the chest and sometimes on the flanks than in the reproductive plumage. The medium and secondary major cover feathers are noticeably bordered with beige. They generally lack the pink coloration on the chin and throat - which may be beige, yellow, or light salmon - and the crimson wing patch - which may be rust, orange, or gray - typical of second winter plumage.
