Reddit reviews Aspects ASP155 Window Cafe Window Mount Bird Feeder Holds Variety of Seeds & Blends

We did 2 things - we added UV reflective stickers like this. We also added bird feeders that suction to the window like this. It helped, but hasn't completely resolved it. Plants should also help slow them down. Finally, I went to the Hawk Mountain Sanctuary not too long ago and they have installed these things that they really like and have prevented a lot of deaths. Cheap and easy to DIY - so we may try that next year.

We have 2 of these window mounted bird feeders and we love them!

It takes a while for the birds to notice them but once they start coming it's amazing. You can enjoy the birds from your sofa.

We use safflower seed that doesn't attract squirrels. The bottom part slides out easily to refill without having to remount the suction cups.

Good luck!

I'd recommend:

1. One that has drainage holes on the bottom, and
   
   
2. The part that holds the seeds is removable to make it easier to clean and refill without having to unstick and restick the suction cups every time. i.e. the whole thing should NOT be one solid piece.
   
   Also, the bigger the 'roof', the better for keeping the seed dry.
   
   I've had this one for ~5–6 years; it's still in good shape and I'm still happy with it. But any that meet the above requirements should be good.

You're saying if it's too big they'll poop in the food? So this one would be a bad idea? https://www.amazon.com/Aspects-ASP155-Window-Feeder-Variety/dp/B000CSJ1VE/ref=sr_1_1?s=lawn-garden&ie=UTF8&qid=1510712313&sr=1-1&keywords=Aspects+ASP155&dpID=518BuRKUMML&preST=_SX300_QL70_&dpSrc=srch
