Owl Colour Morphs and Fitness
Hi folks,

a couple of recent articles about owl colouration:

Tawny Owls Change Colour as Climate Warms (BBC News)
Link to original (open source) paper in Nature Communications

Brilliant Feathers of White Snowy Owls Dazzle Rivals (BBC News)
Link to original paper in IBIS journal

Cheers,
Marc.

Re: Owl Colour Morphs and Fitness
Its interesting stuff on the Tawny owls especially. I didn't realise there were even two colour morphs. I vaguely remember reading that the white stoat winter colour form (ermine) is reducing in the more southern end of its range too.
