I get several a year that trap in and they will usually keep trapping in. I think they like having a nice place to stay, food, clean water and companionship.
Before there were a lot of coopers hawks in my neighborhood I had around 20 ferals that would spend most of the day trying to get in my lofts and eating the food some of my birds threw out of some indvidual pens I had. I could walk up and pick some of them up.
Most of the ones that show up are fancier colored young birds. I think they see birds I have that look like their parents and are attracted in. I get a lot of reds and heavilly pied ferals coming in.
Last Thursday a friend of mine gave me a dark check that has been flying with his homers, when I was purchasing some homers. He has let it go on 60 some training tosses and it keeps coming back. It originally came back with his homers from a toss.
Tuesday another friend had me take a blue check and a black feral that had moved into her white homer cross loft.
My Grandfather Malone, back before I was born, only had common pigeons he had caught. He had his loft set up with a drop trap specifically so he could catch commons. He would keep the ones he liked that entered.
