As Raquel García-Álvarez guides hikers on a trail surrounding the Sand Ridge Nature Center, her remarks on flora and fauna are interrupted by geese honking. She explains, as curious onlookers admire the birds skirting the water, that there's more to them than meets the eye.
Geese are known to display"homosocial behavior," she said. For example, there's been documented instances of two male geese pair-bonding with each other.
"This is a bad idea, because nature is much more fluid. It's much more flexible, and there's a lot more going on than just these binary categories," she said., from insects to mammals, engage in same-sex behavior. These relations weren't historically recognized largely due to homophobia, she said. Some theories suggest scientists mistakenly misgendered animals engaging in same-sex relations, while others believe scientists overlooked the behavior to avoid censure from colleagues, Schrefer wrote. Emerging research also acknowledges that some animals have sex for reasons other than procreation, and it doesn't necessarily affect their species' ability to survive.
Later on, a bright red northern cardinal, the state bird of Illinois, perched on a fence in front of hikers. Though rare, García-Álvarez said"bilateral gynandromorphism" is possible among the birds, essentially meaning that they're half-female, half-male. These birds appear almost perfectly split along the middle, with bright red feathers characteristic of a male on one side and pale brown feathers common to females on the other.
throughout the state, got an email explaining the event, the 22-year-old knew it was worth driving an hour from her home in Skokie. She thought the discussion on the cardinals was particularly informative.
