A wildlife-lover was left stunned
after discovering a rare blackbird near his home with both black and white
markings.
Twitcher Kim Oliver, 62, pictured
the unusual bird rummaging for food in autumn leaves on a footpath near a busy
road in Coventry.
The retired photographer said he
has never seen a bird like it in over 50 years of bird watching.
Rather than being albino, the
blackbird's striking colourings are believed to be the result of a rare plumage
condition called leucism.
The defect has been spotted in
many British birds, but almost half of all reported cases have been blackbirds.
A wildlife-lover was left stunned
after discovering a rare blackbird near his home - with both black and white
markings
Mr Oliver first spotted the
bird last week while walking near his home in Binley, Coventry, and said it
took three visits before the bird started to recognise him and not fly off.
The curious creature became so
tame on his final visit that it hopped over to him so he could capture these
amazing images.
Mr Oliver said the stunning bird
reminded him of a Dalmatian dog and was one of the most unusual he had come
across in his five decades of bird watching.
He added: 'I have never seen, yet
alone heard of, this type of blackbird. Albino yes, but not like this.
'It looks more white than black
depending on the angle and it took me three visits to confirm exactly what it
was.
'It is incredibly striking. It's
like a Dalmatian version of a blackbird. I've heard of albino birds but these
markings were different.'
It is not known why the leucism
affects blackbirds in this way- but some experts believe it could down to
stress, ageing or a genetic disorder.
Ornothologist Paul Stancliffe,
from the The British Trust for Ornithology (BTO), said: 'To see a blackbird
with the odd white feather is not that unheard of but the more white you see
the more rare it becomes.
'There are only two or three
reports a year of white blackbirds, such as this so it is rather uncommon.
'There are several theories as to
why leucism occurs but nobody knows for sure.
