Do you have any of those blood relatives who look so different from everyone, you wonder how they’re even related?
In the 1870s, ornithologists described Brewster’s Warbler and Lawrence’s Warblers as two distinct and separate species.
However, scientists eventually discovered both actually had the same parents, and instead were hybrid crosses between Golden-winged and Blue-winged Warblers!
The differences come down to how plumage traits are inherited across generations. It’s a fascinating example of how hybridization can complicate bird identification and our understanding of what even makes a species!
Explore the surprising science of hybrid birds during our November 18–19 online seminar. Two days of live presentations and discussion for just $25!
All proceeds go toward our youth scholarships.
