About 8-9 soaring in circles, distinctive lighter trailing edge of wings (not visible in picture)
Would like to know what this is, I hear it often. In mid successional mixed conifer/deciduous stand.
This bird was singing at night. Both calls are from exact same direction in a tree.
At least 20, mostly males
Very far offshore so I could be wrong, but overall colour seems to match. Half of group black/white and the other half a warm brown. Large group
