This is a fb post from one of my cousins. It seems there are illegal aliens even in the animal world.

"I got two ferns hanging on my porch that I got for Mother’s Day ! I have seen a bird flying in and out since the first day I hung it. I took this pic while ago and holy moly I didn’t expect that many eggs. I sent the pic to Chat GPT since the one egg is much larger and speckled. Chat GPT said 5 are finch eggs and the large egg belongs to a brown headed cowbird because they are notorious for laying their eggs in an occupied nest so the other bird will raise their chicks. OMG leave it to me to have a crazy bird!"
