Pigeon Smidgen does the pigeon mating dance when it sees a live pigeon but only using a model of the male pigeon's reproductive system (testicles, vas deferens, and cloaca). For birds the testicles are internal and thus, unlike for primates like us, not a part of the visible sexuality of the animal. Therefore the robot's sexual advances involve the right gestures with the wrong parts.
In "Are you My Lover?", its computer vision system tuned to a wide variety of bird species to avoid missing a pigeon (machine learning isn't perfect), the robot has also selected the wrong mate.
In the children's book, "Are You My Mother," a baby bird that looks not unlike a scrub jay searches the world for its mother, naively asking a variety of animals and objects whether they might be she. The baby bird's thinking a backhoe might be the mother it seeks reminds me a little of Pidgen Smidgen's guilelessness in its interaction with this jay.
