The most likely explanation – as judged by the authors – is something called the farming hypothesis, which states that brood parasites such as the koel may deliberately destroy nests as it gives them a good chance to deposit an egg in the replacement clutch. Why do nesting attempts of the Red-billed Blue Magpie sometimes fail?

Isla Rasa was declared a sanctuary in 1964, and egg-collecting and disturbance during the breeding season are discouraged. You know what one of my favorite things is about bird blogging? It’s all of the things I learn about different birds from researching to write posts.

I’ve organized them by date (month/day) of the approximate reporting or blogging time of the item of interest, which does not necessarily reflect the actual date of occurrence. Birds are raised from the egg to follow a certain migration timing, but that timing shifts when the egg hatches later or earlier due to changes in conditions.

They emerged from their bloody rampage leaving fifteen adults dead, and fifteen destroyed nests with either smashed or missing eggs. There are eggs that are not viable, nestlings who fail to thrive, natural predators who snatch a chick for a meal, freak storms that blow through and destroy part of a population.

To be honest, both the robin and the flycatchers shown above remind me of the easter eggs I hunted for as a child – the same strong colors in front of a green background, same time of the year (feel free to insert your own Proust Madeleine reference here) … Bluethroats apparently are good at imitating other birds.

But seriously, Science has a more interesting set of answers, and some recently published research on European Robins helps to examine this question in some detail. How the quality is demonstrated is the subject of one or more future blog posts, I’m sure. Why are any of the parts of any birds colorful?

But then again, it could be due to the fact that we are constantly bombarded with billion-dollar advertising campaigns from the meat industries, the dairy industry, and the egg industry, as well as from myriad restaurant chains that promote and sell these very animal products.
