I have been seeing my blues all fall & into the 1st week of December at the suet bowl, but have not seen them for about 4 or 5 days now. Believe the NUMEROUS winter birds here in Missouri (Juncos & white-crowned sparrows) are keeping them away. And of course, the HOSP are around, too, eating the suet. I use two cage feeders to exclude the larger birds (they have their own sunflower feeder) but those small birds are just thick. Oh, well, can’t control wild birds, but I sure miss my blues and hope they return soon and that they are okay.
