On a trip to Florida years ago, I walked along the beach marveling at the shorebirds and giggling as they ran away from a wave and then just as quickly ran back as it receded to poke in the wet sand for tasty morsels.
They were such a pleasure to watch, so busy in their task, that humans walking by were of no concern to them. If they only knew how much damage those humans are doing to their coastal environment, they might not be so tolerant.
These birds are really long distance travelers with many migrating from the top of the world to the bottom of the world, often with only one break per trip.
As I read the following article from the New York Times, I was amazed at their resilience and the conditions they have to endure.
