观察细节
- First found and reported as an Am. Black Duck 18 April. - Apparent 3rd spring record for Missouri according to Robbins (2018). - Observed the bird on two separate occasions today, once in ditch just outside of refuge with BWTE, and later in morning swimming in slough along HQ/maintenance buildings by itself. Very skittish, both times quickly took flight almost as soon as I noticed it. - Warm brown bird overall, not as dark as Am. Black Duck; buffy chevrons on body, with obvious pale head and neck. - Bill drab olive/yellow - Not the bright yellow as depicted in field guides for males so assume this bird is a female. Very thin black to gape. - Bright orange legs - White trailing edge to speculum very narrow as indicated in flight photo. - Crown and back of neck slightly darker. - Throat clean buff. - Dark line through eye.
