This week, we walked across the Engbertsdijkvenen. We spotted an uncommon bird, the Bluethroat (Luscinia svecica). Helped by the app Merlin Bird ID, an app that lets you listen to birds like you’ve never heard them.

We also spotted Homo copiarius avium, a species of Homo sapiens equipped with a still camera with an 800mm lens. I can estimate this species quite well since I am of the affiliated subspecies Homo copiarius platea, also outfitted with a camera, but with a 28 or 35mm lens. Whereas the Homo copiarius platea like me is more often found in inhabited areas, where it generally operates in isolation, the Homo copiarius avium is found in nature reserves, where they operate in groups of 3 to 7 of their conspecifics, and often congregate in observation huts to share their collections of copied birds.

Ben van den Broek made this picture of the Bluethroat.
