Wow they're precious & you're awesome to save them! Who dumps precious birds like that? I wonder if you could set up a camera where they're parking, get pics of license plates when they drive up.
Bless you for caring.
I rescued a swan once, fully grown, big girl! I found out that her owner had died, nearby neighbors answered my flyer about her. Not sure who took her to a pond & left her there, but she only recognized pelleted food, she would've starved if someone hadn't called me. I took her to an avian rescue 2 hours north, they fed her & found her a forever home on a farm, where they had a grieving male swan, his mate had died 2 months prior. He & this lovely lady swan took to eachother, snuggling right away.
Birds are wonderful.
I wish everyone realized it & was as kind as you.
