Are you
sure he can't see himself? Other people who know more about bird vision
will be able to comment on that - I don't know the answer but I would
suspect the glass is still reflective. Have you tried covering the inside of the
window with butcher's paper or something similar? Not very aesthetic for you but
might work?
cheers
storm,
Hi
Trevor,
I just read this email on
the Birding-Aus website. We too have this exact problem with a raven at the
moment - did you find out how to stop the bird doing this? He spends the
majority of the day (from when the sun rises to sun set) flying against and
scratching his claws against the window. He "grabs" at the window with his
feet while flapping his wings against it. He will pick at the rubber seals
with his beak too... Not only is the noise extremely frustrating, but our
window sills are now splattered white. The other strange thing is that it
doesn't matter whether he can see his reflection or not - he does it even when
he can see right through the window. He will fly away if someone comes into
the room.
We have tried sneaking
up and scaring him away... but he only moves to nearby tree or another
window.
Any advice?

Dear
Birders,
Over the last two weeks my wife and I have witnessed some unusual
behaviour in a Little Raven. By far the most common raven in our
district is the Little Raven and it can be seen individually and in
small groups through to loose flocks of 50 or more. A few occasionally
visit our 5 acre block on the outskirts of Murray Bridge (80 km SE of
Adelaide).
One individual has commenced regular visits to our front
verandah. We think he may have been attracted initially to a box of
apples (since moved inside) but he now visits daily, sits on a cupboard
under the window, calls loudly and then repeatedly flies against the
glass as if attacking it. He may do this 15 to 20 times a day, more
frequently on overcast days. It has now taken to banging against other
windows, even some on the other side of the house. The main window
attacked has a westerly aspect while the others have a southerly aspect
and easterly aspect recpectively.
I've never seen this kind of behaviour in a
raven before.
It is becoming a little annoying after all this time and I'd
hate to see it hurt itself.
Any comments?
Happy birding,
Trevor Hampel
