February 2009 - One of the most reliable plumage differences between Short-eared Owls in their first year of life (i.e. hatch-year/second-year) and older individuals appears to be the tail - specifically the central rectrices.  On young birds such as this specimen, there is a distinct dark triangle at the tip of the shaft of the central rectrices; the pattern on the feathers is also typically rather similar to that on adjacent feathers, aside from the dark spots in the centre of the pale bars.  (Photo by Marcel Gahbauer)
