Birds flying into windows, stickers effective? Blackbirds

I have about a million apples on the ground that I haven’t picked up. Luckily I have a garden full of birds eating them, mainly blackbirds and fieldfares.
A blackbird flew into the window a couple of days ago and died, and another one just now. They aren’t a bit stunned, they are bloody and dead.
It was a different window.
I have ordered some window stickers, but Mr Google thinks they are ineffective.
I would not be happy with curtains, nets or shutters, but everything else I would consider. Something hanging down on the outside? I do hope there is an answer, I love my blackbirds.

 

I read that you have to place the stickers quite close together, maybe two feet apart, both up and down and side to side. So many, in fact, that you would be distracted by them.

How about moving the food source to a safer location?

 

Oh.
Hmmm the apples are widely distributed about the garden, not particularly near the house. It’s when they are spooked and flying away in a panic that it happens, though I’m not sure what causes this.

 

Well then, worth a try. I was disappointed in the opinions on the internet, but I’ll give it a go.

 

They are quite expensive, as I recall. Choose a design you can live with!

 

Not everyone's choice but if it is only to cover a few weeks whilst the apples are attracting the birds, I have often used the "sticky" Yellow and Black ( = Danger ) tape on certain windows and on my GH - particularly during the fledging season. It has proved successful in my case.

 

We have put up the stickers of predator birds on some of our windows, and that seems to work fairly well. Apart from wood pigeons, nothing seems to deter them, we regularly get them leaving ‘angel wing’ dust imprints on the glass. They don’t seem to be injured though, and fly off. The biggest problem we have is that the birds can see into one window and out through the opposite one, and think they can fly through. We do close a blind or curtain to try and reduce the effect in the spring. It possibly helps that I don’t clean the windows as often as I should.

I tried the black predator bird ones but didn't like the effect in our large main front window. Bought some pale butterfly ones last year and they seem to work most of the time. Have still had one or two finches killed though, sadly.

Like another poster says, the birds seem to think they can fly right through, it's a problem for us as we have large window on three sides of the living/dining room. The bird feeders are near the front window, where I can watch them from my chair.

 

I've just seen this thread and I wonder if this stuff is worth trying. I have the stripey one on the bottom half of the large single pane on my lounge window, just as an alternative to a blind. It allows light in, but gives some privacy, and it just 'sticks' to the glass by applying some water.

There are lots of patterns available. Easy to remove later. It would just block the glass a bit, without affecting the light too much, and you can arrange it so that there are gaps etc.
I had the same problem on my bedroom windows because, although they're the smallest of all the back ones, they're nearest the feeders and the flight paths. I got a blind for that, and it's only ever half down at most, and that's done the trick, so maybe the plastic stuff would work even if you just did a central stripe or similar.
