This female house sparrow arrived in the garden today. What can have caused the white markings?
Do you think it is just genetic or could shock have turned her feathers white like what can happen with people when their hair turns white after a traumatic experience? On Thursday a sparrow hawk attack left them quivering in the ivy too scared to come out for ages.
I have one sparrow with a totally white tail which has been around for more than a year now but I have never seen one like this before.
