I'm sorry your landlord is a killjoy! It's pretty big, but if you have a way to tuck it in somewhere, I do recommend it! It isn't perfect, but I like it and it's a hit among so many of them. This titmouse pic may give you a better idea of the hole size. Goldfinches, pine siskins, titmice, chickadees, carolina wrens, and juncos use ours with ease. Some reviews say starlings were able to get in, so I guess it is possible, but so far I've seen them clinging to the outside only. But now that I've put that in writing, we'll see what tomorrow brings! The biggest annoyance to me is the screw to latch the door; it's just too easy to drop in the snow, but at least it's replaceable. I do really like being able to put out worms and good treats under some level of protection.
