0930 - plum. (Grousecrow) Bird in top of 2 foot
high lupinus. Bush has many flowering stalks
with closed buds + 5 stalks on NE side that are
in bloom. Bird is pecking at closed buds then
apparently eating some tissue inside + the outside
bracts dropped off the side of the bird. Once thought
it took some small leaves from near top of bush.
Feeding in this way for 3+ minutes then flew up well
