Window Bird Feeders with Strong Suction Cups, Clear Window Bird Feeder for Outside - Transparent Bird House, Balcony Glass Mount, Acrylic Cat, Kids & Elderly Viewing Clear Bird Feeder for Window Perch

The feeder is robust and well-designed and the suction is excellent. It took a few weeks for the small birds to notice it and pluck up the courage to use it, but they are regular visitors now. It helps to have a tree or hedge nearby so they can approach gradually. Luckily the jackdaws and pigeons don't come that close to the house and added bonus, mice and rats can't get to it!

Very good quality and value for money. Small birds ate from it within 2 days but it was only 3 days till the big birds sussed it too.I give it 5* because of the quality but disaointed that the large birds can use it too

The quality and value of this item is tremendous and a delight to watch from my window with a variety of birds using it

It’s a good idea but u need to be patient because it seems to take a while for birds to use it.

Brilliant. Birds love it

Be patient, it takes the birds a week or two to get accustomed to it, but once they've realised it's got yummy food in then there's no stopping them. We love watching them hop on and fill their beaks.

This quickly arrived well packed in an attractive box. It is made of thick and crystal clear 'perspex'. Much better than a cheap previous one I had, and the birds took to it very quickly. Very easy to clean and refill, and the 4 suction cups are very robust and effective. But sadly, because the seed tray just rests on the shelf, instead of running into a slot, or having a projection to retain it, my tray blew upwards and out down onto the patio below, even though it had a full load of sunflower hearts to weigh it down. It landed face down and no damage was done. But when the wind got up in the night not long after, it happened again and broke the side of the tray. Very disappointing.

The suction cups really do work well and the larger size is excellent as there is more than one bird at a time feeding. Well worth buying

Arrived extremely quickly. I'm very happy with this. It's is solidly constructed, it was easy to affix to the window, and the suction cups are very strong. I can't get it to budge. It's not going anywhere. It's only been up for an hour, so no birds yet, but I know there will be tons of birds there soon.I've attached a picture of what it looks like on my window. Excuse the dirty window -- I couldn't clean the inside window because another pane of glass is in the way because of the air conditioner. I will post more pictures once birds find it.

The media could not be loaded.  First of all, I want to dispel the myth that window bird-feeders are dangerous for birds. There are two reasons that birds collide with windows: Either they are trying to escape predators or are unfamiliar with the area. Placing a feeder in the middle of your window will break up the reflection the birds see of your yard, and they will be less likely to try to "escape through your window". I have noticed that birds who are using this feeder for the first time may have a hard time landing right on the perch, and may flutter against the glass for a second. But once they have landed and gotten their bearings, subsequent landings go smoothly. Birds that have visited the feeder a few times may occasionally land on top of it accidentally before flying down to the perch, but don't flutter at the window.Installing this feeder in an area where there has not previously been a feeder may result in a long delay until birds find it. On one of mine it took three weeks for the first bird to arrive. Once there is one bird on it, however, others will quickly notice the food source and will arrive more often. If you are having a hard time getting birds to locate your feeder, leaving scattered piles of the same bird-feed on the ground in the area can attract birds who are used to looking for seed on the ground, and when the original pile is exhausted, they will look for similar seed in the vicinity and find the feeder.From a design stand-point, this feeder is top-notch. The construction is great, and the plastic is very thick (1/8" plexiglass) and sturdy. Overall it weighs about a pound. It will withstand Oregon rain (the all year round kind) and the seed is able to drain well since the removable try and feeder box both have drain holes that work well. The suction cups are large and adequate, though mine were a little misshapen from being squished in a bag during shipping. You can just let them sit in warm/hot water for a few minutes to revert to their natural shape. Dry them well, and then (I know this sounds weird) rub the suction cup on your nose. The oils from your nose will help plug any minuscule cracks and prevent air loss that would make the suction cup fail. Stick the cup onto a clean window, and it'll stay up for years. (Though you are taking your feeder down for regular cleanings, aren't you?)With no rain, you can safely leave the feeder out without cleanings for a month or two. With rain, depending on your type of seed, mold can form in the feeder. You'll see when this happens, and you can remove the feeding tray, and throw it in the dishwasher. (I think the bleaching instructions are overkill. Your dishwasher will kill anything growing on the feeder.) Depending on your window, you may even be able to remove the feeder from inside, as long as you don't have a window screen in place. (If you try this, attach the feeder to the window that DOESN'T slide.) I can slide up my window, lean out a bit, and reach up to the feeder and grasp the center feeding tray divider, and lift it out. While mine is only on the first floor it keeps me from having the push through my hydrangeas to get to the feeder. It would be no problem for someone on a second or higher story from servicing the feeder from inside the house.I appreciate the fact that the included feeding tray is removable. (Apparently, earlier versions of this product didn't have the removable feeding tray.) Because the feeding tray is also divided, you can also have two different types of foods, to see which your birds prefer. (I've had the best luck with sunflower hearts, but your local birds may have different tastes. Or you may choose smaller seed to bring in little birds and not the jays) While there are drainage holes, there is no issue with small seed like milo, sorghum or thistle. It won't fall through. (Some of it may fall between the feeding tray and the outer housing, so you'll have to blow or wipe it out when replacing the feeding tray.The "roof" of the feeder hangs down enough to keep out most of the elements, and I haven't had any issues with the black landing strip coming off. I've seen some feeders without this strip and i think it'd be much harder for the birds to land as easily as they do on this one. (not being able to gauge where the edge of the plastic was, if there wasn't a strip.)The birds will often poop as they finish feeding and fly away. If you have decking or some other "pretty" surface under the feeder, it's likely to need regular cleanup. Depending on the type of seed you use, you'll also have piles of shells all over the ground. Some birds will also root through the seed and knock some of it to the ground. I have mine over flowers, and don't have to deal with the poop issue, or a pileup of seed husks. The birds will happily eat the extra seed that falls to the ground.The feeder is a resonant box, and so there is a noticeable sound when the birds land. I can clearly hear tiny finches landing, when I'm in the room, though the sound is subtle. I can easily miss it if I'm typing on my laptop when they land. Larger sparrows landing result in a loud click, that I can hear over the neighbors mowing the lawn if I'm in the same room. (Take a single sunflower seed and toss it against a window as softly as you can, and that'll give you a rough idea of what it sounds like to have a sparrow land.) Larger birds like Jays are unmistakable, but the sound isn't intrusive. (I mean, but really, if you put up this kind of feeder, you do it so you can see the birds. Why wouldn't you want to hear them arrive?)The feeder is completely clear, so it can be challenging to approach the window with the feeder when birds arrive without them noticing you and flying away. One approach is to walk slowly. Also turning off any interior lights will make you harder to see. You can also lower blinds if you have them, and rotate them so they are slightly open. This makes it easy to walk right up to the window and peek between the slats to easily observe the birds really closely. Though over time, regulars will grow accustomed to general movement in your home, and won't fly away unless there is sudden movement. It's not uncommon to be able to slowly walk to the window with birds that have been feeding at the feeder for weeks, and stand nose to nose with the window watching them from up close.The only drawback to this feeder (and it's a small nit-picky one) is that bird are often back-lit. In other words, they are in the shadow of the house, while everything in the background is sunny. So trying to take pictures of birds in this feeder can be challenging, except at times of the day when the sun is mostly overhead. At other times of the day pictures usually come out underexposed, while the surroundings look lush and well-lit. I've had some better luck with the room lights on. Flash photos have been complete failures, with the pre-flash lights scaring the birds right off. But, I'd rather have mediocre close-up pictures, that well-lit pictures of birds across the yard. Or, I just have to wait until the light is just right.Overall, I'm very pleased with this feeder. It is my favorite feeder that I own, and I'm sad it took me so long to find it. I highly recommend it.(You can see in my video how protective the Pine Siskins get over the feeder sometimes! )

Giving this thing 5 stars today because we just had the craziest weather and it has. not. budged. This thing is still stuck to the window as good as the day I placed it. We had incredible wind, downpours, lightning, floods, rock sized hail, all in one day and it is still in place! In between the precipitation little birds were coming out to get more feed. My cat also loves this. She will stalk the birdies and watch them from her perch. 5 stars all around!

Let's get the deficiencies out of the way. My feeder did not come with the extra suction cups.The feeder is easy to install, easy to clean and sturdy. The birds love it to the point where they fight over who can sit in the wells. Yes, the birds sort of nest in the wells whilst eating--especially the finches. The birds also perch on the rubber/vinyl enclosed outer lip and the chickadees often will sit on that whilst they crack the sunflower seeds. The feeder provides a lot of enjoyment for us as well as our cat. We will see how it goes through the winter, but so far no complaints. I gave the feeder a 4-star rating because the extra suction cups did not come with the unit.

First, you should know that there is a yard squirrel named Bugs who likes to provoke my indoor cats. I call him Bugs cause he bugs them. He climbs trees and fences outside their favorite viewing window and wags his tail at them and eats loquats as if they were corn on the cobs, as if his life depended on it, as if he was getting paid $3 per loquat. I’ll come back to this point in a minute.This is a sturdy, well-made bird feeder that did not disappoint in terms of its finely crafted polycarbonate surfaces. I also appreciate how the seed tray is removable for easy cleaning, and fits precisely within the parameters of the outer shelter structure. The weep holes for moisture drainage are also precisely laser cut in both the outer structure and the tray itself to line up with eachother. Words cannot describe the satisfaction I got by traipsing out to the narrow edge of my yard with this pristinely made feeder, wiping the residue off my living room window from a rainy Los Angeles winter, and pressing the very powerful suction cups in place. All that was left to do was gently place the feeder on the hooky parts of the suctioners and the feeder was open for business for my avian menagerie. I have had this feeder suctioned to my window for over 3 weeks now and have only seen Bugs the yard squirrel enjoying the fresh and delicious seed mix I filled it with. I think the reasons for this are several-fold:1. Maybe the birds are coming, but it is during the time when I’m away from the house longest so I’m just not seeing them.2. I placed the feeder such that the bottom of it is just about 5-6” above the outer window sill below. So yeah, my bad, I didn’t realize yard squirrel could simply then hop over from my rickety property line fence, roughly across 18-22” of weedy nether regions and onto the outer window sill, mosey up on his hind legs and feed at the seed trough like it was his own personal Regal Beagle at happy hour.3. Remember back to #1 again, how I said maybe I just missed out on seeing birds experience the feeder since I was away for hours at a time. Because I’m lucky enough to be saddled with the responsibilities of having a job and having pets that I love, I often feel guilty about leaving my pets (cats) home alone for what can sometimes be a long work day. So I seek ways to make sure my cats stay busy, don’t get lonely, and can keep themselves entertained. This is what led me to make the other greatest amazon purchase of my life, a double decker suction cup cat window bed. I use the generic title, but you can easily find the product, I’m sure they’re still making it. It’s like bunk beds for cats. And my indoor girls looooooove it. I haven’t had a cat that didn’t love it. But after years of use, it just wasn’t enough. I felt the cats were showing signs of ennui that no feather toy or crinkle ball could cure.4. So yes, I bought this window-mounted bird seed feeder for the primary purpose of suctioning it to the opposite side of the glass as their cat bunk beds, so that they could presumably lay in their little bunk beds and watch birds flitter up to the window all day to snack on seeds.5. But nature is not that idyllic, and cats’ instincts are to kill birds, and birds are too evolved to let nothing but a piece of plate glass stand between them and their greatest predator, even if it means getting to peck at few scant sunflower seeds before the cat swats at them from the other side of the glass loudly enough to get their little pea-sized bird heart palpitating so wildly that propel themselves up towards the sun like little phoenixes blinded by the light.So in conclusion, although this bird seed feeder might do best to serve birds outside a cat-less household, it’s a finely engineered polycarbonate beauty, and I’d highly recommend it to anyone still reading this.
