Do Crows hold funerals? Nah, not really, but they're up to something when one among the murder is murdered, and scientists are fascinated by their behavior around fallen comrades.
Calling to each other, gathering around, and paying special attention to a fallen comrade is common among the highly intelligent corvids, a group of birds that includes crows, jays, magpies, and ravens, says Kaeli Swift, a Ph.D student in environmental science at the University of Washington. (See "Are Crows Smarter Than Children?")
But it doesn't necessarily mean the birds are mourning for their lost buddy. Rather, they're likely trying to find out if there's a threat where the death occurred, so they can avoid it in the future.
One study involved using masks to see if crows would avoid humans who handled dead crows (and thereby implicated themselves in the investigation.) They did. On the other hand, if crows are smart enough to investigate murders, maybe they're smart enough to take one look at that mask and think: "OK, that is definitely a murderer."
Peregrine falcons are the dive bombers of the natural world, flying at speeds over 200 mph to snag their prey.

If there’s one thing that stayed consistent through the last decade or so of tech industry turmoil, it’s the love affair between techies and Linux. There’s just a ton you can do with the OS, and its open-source format means you can customize your rig from the ground up. Apparently not content with that level […]
Accidents happen. And when they do, you’re going to want a dash cam for a second pair of eyes. At the minimum, a decent dash cam can save you vast sums of time and money in case of an accident. But a really good dash cam can do a whole lot more. Here are six […]
The field of data analytics is growing as fast as the internet itself. Self-driving cars, airline pricing, and huge marketing campaigns are all driven by the insights that data scientists can distill out of vast sums of information. Even with the help of powerful software like Python, it’s a highly skilled position. But those skills […]
