Moults and plumages and testicular regression of post‐breeding male Blue‐winged teal ( Anas discors) and Northern shovelers ( Anas clypeata)
Moults and plumages and testicular regression were compared in post‐breeding male Northern shovelers ( Anus clypeala ) and Blue‐winged teal ( A. discors ). Sequence of moults and plumages was similar between species, except that Northern shovelers became flightless before completion of pre‐basic mou...
