Native plants are better for birds than non-native plants.
That’s the main finding of a study on chickadees and the caterpillars they eat.
Desiree Narango is the lead author. She’s a research fellow at the Smithsonian Migratory Bird Center and a PhD candidate at the University of Delaware.
“From the chickadee’s perspective, it’s as if a non-native plant isn’t even there at all because they almost never forage in them,” she says.
