Gravel-camouflaged nests give threatened shorebirds a boost

When it comes to reproduction, not every individual equally pulls his or her weight. Researchers spent 13 years tracking the reproductive success of individual Snowy Plovers, and more than anything else they considered, the one factor that stood out was whether plovers nested on sandy beaches or gravel bars: gravel provided better camouflage, leading to more successful fledglings, in turn leading to higher lifetime reproductive success for birds that nested at gravel sites.
