This is a great feeder--I have the windows that tilt in and it's very easy to fill. I like that the top of the feeder is on a string so it doesn't fall out the window. I generally use safflower seed. The finches love it and it's very cool to be able to look at them close-up without scaring them away.

This feeder arrived during a cold snap. I placed it on a window the birds were familiar with and within hours we had chickadees, finches, cardinal (male only; female comes near but will not land on it) and nuthatches. It's a little hard to see through the reflective film and since the birds seem used to movement inside the house, I might take the film off the next time I take it down for cleaning. Also, I wish both parts of the funnel and cap were attached by cord to the feeder since dropping the funnel part means a trek through the snowbank to retrieve it. It's not uncommon for 4 or more birds to be at the feeder at once. All in all, it's a great feeder!

This feeder arrived in February, with record low temps and heavy snow cover. I mounted it on an established bird-feeder window and within hours we had birds visiting. We regularly see chickadees, finches, cardinals, and nuthatches at the feeder and it's not uncommon to see four or more birds in the feeder at once. It's easy to refill and I like the lid that turns into a funnel, but I wish both parts of the lid were attached to a cord as dropping the unattached part means a trek out into the snowbank. The reflective film does limit your view of the birds and I will probably try to remove it the next time I take it down for cleaning as the birds do not seem bothered by activity inside the house at other window feeders.

Love this feeder. Put it up on my window at work and I now have birds feeding at my window all day long. Very easy to fill. It gets enough bird action that I need to fill it every few days. Love the funnel option. It makes it very easy. Others in my office come by my office just to watch the birds. Have not seen any issue with birds fighting. They do get pushed off as other birds fly up to use the feeder.

Absolutely love this feeder. Attaches easy to the window and stays put. Easy to keep filled. I had Mr. and Mrs. Cardinal within an hour of putting it up and they feed daily. I know when they arrive as they peck on the perch and sing while eating. Best of all, the squirrels can't get to it. I placed this on my window along with another Duncraft window birdfeeder and between the two I have my daily visitors of cardinals and chickadees!
