Summary

We might assume it's because the grass is greener on the other side. But this month's study suggests that some migrant Sanderlings headed to the tropics are getting less than they bargained for. Tune in to our chat about the costs and benefits of migration, the importance of falsifying hypotheses, the logistics of studying a species over 13,000 kilometers, and how wintering habitat can make or break success on the breeding grounds. Find the article here: "Low fitness at low latitudes: Wintering in the tropics increases migratory delays and mortality rates in an Arctic breeding shorebird" (Reneerkens et al 2019).

Miller (1868 - 1961) LibriVox In 1903, Panama became a brand new state in Central America by seceding from Colombia in order to facilitate the construction of the Panama Canal, which was finished in 1914. This fledgling nation was home to the oldest inhabited European settlement on the American continent, a rich indigenous culture, and a splendid natural beauty from coast to jungle. Such was the scene as found by George A. Miller as he was "Prowling about Panama" in 1919, an activity that is more a "getting lost in the right way" than systematic exploration. Follow the author on his prowls through an amazing country that at the time of writing was an exciting mixture of tradition and modernity. (Summary by Ava).
