Summary

Not all brood parasites are on the hunt for an unsuspecting bird of another species to take advantage of. In fact, there are many bird species who lay the occasional egg in the nest of a same-species neighbor. But is this behavior actually parasitic? For many waterfowl species, it may be that both host and egg-layer benefit from the arrangement. Join us for part II of our brood parasite mini-series, as we discuss "Brood parasitism, relatedness, and sociality: a kinship role in female reproductive tactics" (Andersson, Ahlund & Waldeck, 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).
