Hmmmmm, you sure about the first time for these visitors, or the first time you have noticed your visitors?
Farmers, you live in the country?
Many farms have pigeon flocks, I have met some farmers and asked them if I could release pigeons there.
I found this one farm, a whole huge building full of old tractors, and Pigeons nesting all over the place, the flock was about 60 strong, this farmer was very nice and gave me permission to release birds there, plenty of grain, a stream nearby, the natural preditors keep things in check...
As a Rescuer and knowing how many rescues come my way each year, I knew I would be in trouble soon with only so much loft room, so I had to find a safe haven for my rescues to be released, there are 3 grain elevators here with pigeon flocks, these are my second choice, the farms are my main hope.
I never just release, I ask the farmers first.
Could be there's a feral flock around your home, I thought you lived fairly close if not in a city.
But someone close has a flock of Pigeons.
