Marina Castellino and her sister Marcela share a love of birds, especially those living in Mar Chiquita, one of South America’s largest wetlands. Marina got inspired from seeing her older sister’s love for shorebirds. The two sisters helped get Mar Chiquita declared a National Park and National Reserve for Argentina. That supports birds like sandpipers that migrate between South and North America. So if you see one near you, efforts from Marina may have helped you see it there!  More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.
