Birds such as cardinals (red birds) and robins will dash repeatedly at their reflections in windows. Such actions occur because the individual bird, usually a male, mistakenly perceives another bird in the reflection of the window. It is territorial behavior for the bird to fight off the ‘intruder”. This behavior, if continued over a period of weeks or even an entire season, can be annoying to people, but is usually not fatal to the bird. On the other hand, when a bird strikes a window in free-flight, it does so with such velocity that the results are significantly more serious.
Robins are quite aggressive birds and will defend there territory against another male. It sounds like your one caught site of his reflection and assumed it was an intruder. He obviously was quite determined to repel the other bird and attacked it all day. No doubt it was looking quite aggressive! He gave up at dusk either due to a headache, or more likely he was unable to see his reflection, and assumed he has sucessfully banished his foe. To stop him doing this in future, make sure you keep that room well lit, so he will be unable to see his reflection in the glass.
Why does the same bird keep flying into my window?"
Is it mirrored glass ? It is probably flying into it's reflection
Because they can't preceive the surface of a window when it is not sufficently reflective. Also the window can reflect sky, which can mislead the bird.
A bird's eye sight does not allow it to see a pane of glass. Or, more accurately, its brain cannot identify the window as a solid object. All it sees is the outdoors, and freedom.
cardinals are territorial,he's fighting his reflection.
keep the window closed! if that doesn't work you got a weird cat
Why would you want to keep them away???
Its a Goshawk!! Am 100% sure!!
Put spikes on the window sill. Just kidding. Try putting food somewhere far away from the window sill. Maybe it will draw the birds away from the sill and towards the food. That might not work. If you are already feeding them, then try stopping. The spikes are a real solution. There are strips of plastic spikes that, when properly installed, the birds will see and will avoid. How the strips will look on the sills is another problem.
It could mean that the bird that is plucking the other one wants to be in charge. depending on the bird you have. a fischer's lovebird is very territorial and can kill another bird if it doesn't keep it's distance. the first bird wants to assert his dominance and instill fear in the other bird.
by flying to a warm place
If you hold on tight.
He or she is sees his reflection in the window. I would put a picture of something uncomfortable for the bird (owl, hawk, etc) in the window. A best way to keep a cardinal from continuing to fly into your window is to put a different colored curtain up. They are attracted to certain colors.
Because you must have something in your house it wants.maybe just try open the window and see what it does.Or it could be a young bird and it probably doesn't know what its doing.
A good place for beginners is out in the open, but not for too long once the birds start coming. Move it slowly towards the trees so that they will not be looking for it. Another place that is good is near a bird garden. When they come for the flowers, they will see the seeds. If you put one on your window/windowsill, put up sun-catchers to try and keep the birds from hurting themselves by flying into the window pane.
Sometimes birds will see their reflection in the glass and attack it, thinking it is another bird. This is especially true for male birds during the breeding season, who are defending their territory against rival males. Imagine the frustration when he attacks his mirror image and his "rival" refuses to be driven off!
to keep him from flying away? do you mean one of those identification bands?that is so if the bird get's lost it can be found
Simply because the weight of the bird, coupled with the down-stroke of its wings - is enough to keep it in the air.
People clip the feathers on one wing of a bird to keep it from flying away - it prevents them from getting enough lift and flying straight, so they stay in one place. If you figuratively clip someone's wings, you keep them from being free to leave.
The birds are establishing their territorial rights for mating season. They are reacting to the bird reflected in the window.
This would depend upon the zoo, but I think for the most part the answer is no. Most zoos that I have seen either keep their bird displays indoors or they have a large overhead net to keep the birds from flying out. Clipping a bird's feathers prevents him from flying, which is not healthful to the bird. For pet birds, this can be tolerated if needed because they don't need to fly much anyway, but even then it's still better to let them have their feathers and be able to fly.
