Strontium isotopes in bedrock and water show a general east–west gradient in North America [15,35], a pattern that has also been shown to occur in knownorigin bird feathers [17]. In this sense, strontium isotopes are complementary to light isotopes (especially O, H) which tend to vary in north–south gradients in North America.
