Heterochromic Corvids

Springwatch‘s corvid mashup inspired me to share this interesting little video I captured in the early summer of 2012. It is footage of a jackdaw, Corvus monedula, eating at the bird feeder in my garden. The unusual thing about this jackdaw is its heterochromia, or eyes of different colours. I am still none the wiser as to the prevalence of this particular genetic trait within the corvids, but I’ve been lead to believe it is a rarity.

I may see if this individual is still hanging about this year, but it’s hard to get a good look when there’s a whole bunch of them going bonkers trying to break my fat ball holder. I don’t know why I said trying… when they’ve already succeeded more than once.

If you have any specific knowledge of heterochromia in the crow family I would love to hear.
