The reasons behind all this window striking is mainly due to the refection birds see when it is brighter outside than inside your house. This makes it very easy for them to see everything that is outside reflected in the glass like a mirror. There are even many instances where the birds see its own reflection and will feel the need to chase that other bird they see (this happens a lot during breading season).
Therefore, this is a topic discussed numerous times every year about the best solutions to get birds to stop doing this.
So, at this point I’m sure some readers have already done some of their own research about different answers to get this stopped. Some for example are:
Sticking decals on the glass
Move bird feeders farther away from the house
Hanging things down in front of their windows
Even replacing windows with a ones that reflect down or bird safe glass
As a result, these techniques can help, but do not always get the job done and can get expensive after trying one thing and then another. Also, I prefer my bird feeders to be somewhat close to my house, so I don’t have to use binoculars every time I want a better look at a bird I see at our feeders. So the easiest, and in my opinion the best solution to this problem is a feeder that mounts directly on the window. And the reason this works so well is because the birds can very clearly see the feeder on the window, and will fly to the feeder to eat then away from the house when finished eating (which the flying away from feeders is the most common window hitting). This is also a cheap way to fixing the problem with window bird feeders only costing $12 to $25 on average, and are great for getting a close view of birds while eating.
I hope this was helpful and that you are able to save more birds from hitting your windows. And for your convenience there is a great new bird supply store online that has amazing organized selections of everything bird watching related with some great deals on window bird feeders as well (please see my resources for more information).
