I HATE STARLINGS but I love most other kinds of birds Starlings are an unfortunate import from England and they are the selfish brutish pigs of the bird world. They bully other birds and also beat up on other birds, keeping them from feeding and raiding or taking over other birds' nests. They were also the disgusting nasty birds in Hitchcock's Movie, "The Birds." I feel that movie displays their true nature, just as "Killer Clowns from Outer Space" displays clowns' true nature. (I am not afraid of clowns but I hate them because their makeup hides their true nature, as in John Wayne Gacy.) I am an avid bird feeder. Not only do I feed them, I provide them housing and nesting materials too. I even buy feather boas and cut them up so the birds can weave them into their nests, and I buy alpaca wool for their nests and even cut up 100 % wool yarn for them to use in their nests. I have several different types of bird feeders, including suet plug feeders, seed log feeders, antimicrobial feeders and feeders made specifically for dried meal worms and of course hummingbird feeders. My neighbors say I have the most spoiled birds in the neighborhood because I make my own plugs for my wooden plug feeders, and I make Seed logs for the other feeders. I even buy dried meal worms in bulk as well as buying dried fruit in bulk to add to my seed mixes. Porch pirates would be really disappointed if they stole from my porch.After i started using feeders specifically made for dried meal worms, I noticed some western blue birds appearing. I was born in the pacific northwest and have lived here most of my life. I had never before seen a western blue bird, but they started coming to my feeders about a year ago. I researched what type of food would keep them close and one was meal worms. I was thrilled to see the western blue birds enjoying the meal worms.THEN THE UGLY STARLINGS SHOWED UP.. Soon, every time I would put out the meal worms, the starlings would show up in flocks, bullying the other birds away, and they would pig down the entire contents of the feeders with a couple hours. I was wondering if there was a starling proof feeder that would keep starlings out while letting blue birds in. I went to a local shop specializing in wild bird supplies and they told me that there was not. I even consulted a wildlife biologist, who told me that bluebirds are a bit smaller than starlings so it might be possible to include bluebirds while excluding starlings.So, I searched for and found this feeder advertised as a starling proof feeder and a squirrel proof feeder. Yes, the price is a bit high, however, it includes two enameled blue disks, one as a lid and the other as a floor, plus a wire grid spaced to exclude starlings, plus a hanging wire and a beautiful blue glass dish to hold the meal worms and a wire framework that you sit the dish in. If you calculate the cost of the two metal disks, the feeder framework the dish and framework, the hanging wire and clamp and the metal cage, you couldn't put one together for the price these are going for.I got this very quickly and put it up immediately. It was evening, so the birds had finished feeding for the day. So, I waited for the next morning for the starlings to show up.Early the next morning, I saw a large number of starlings showing up at the feeders. I hadn't put out any other meal worm feeders, so was watching to see what the starlings did. To my amazement, the starlings swarmed the new starling proof feeder. No matter how much they tried, they could only poke their heads in through the wire grid. They tried repeatedly to cram their bodies into the feeder. None made it in. You could see them grabbing the bars with their feet and pushing as hard as they could to breech the metal grids. Eventually, they would give up and go to one of the seed feeders, leaving the meal worms for other smaller birds.I haven't seen any bluebirds making it into the feeder yet, but will keep watching. Meanwhile it is quite amusing watching the starlings failing at getting into the feeder. If I see bluebirds making it into the feeder i will do an update to this review. However, right now, this is absolutely a starling proof feeder.addendum: just like in the videos I watched prior to purchasing this, the starlings just can't get in. BTW, I switched the worm cup for some Valchoose brand stainless steel 304 approximately 1/4 mesh wire mesh made into a tube that fits into the framework that holds the blue mealworm cup. This is the same size mesh used in the pacific bird wire mesh worm feeder. This is available on amazon and comes in sheets of 12x 24 and I cut it in half at the fold making a 12 inch square. I formed it into a tube , using stainless steel wire ties , I cut the tube into 2 six inch halves, and placed one in the framework, filled it with meal worms and set it back on the bird feeder poles. This should drive the starlings even more nuts. I will enjoy watching that and waiting for blue birds to figure it out.Addendum: I saw another review where the buyer mentioned it would be helpful if there were perches since the bluebirds aren't clingers. Since I hadn't seen any bluebirds in the feeders, I took a 36 inch quarter inch dowel and cut it in half, and shoved the dowels under the metal framework but on top of the floor spanning the feeder, so that they were on each side of the blue meal worm bowl, and each stuck out about 2 inches on each side. The perches seemed to be helpful because this morning, the bluebirds were in the feeder scarfing meal worms. The starlings were still desperately trying to get in unsuccessfully, but the bluebirds were inside and happily eating. THESE FEEDERS REALLY WORK and exclude starlings. I am very pleased.
