Weekend Reading April 4, 2014

One of the most amazing birds I've heard of is the Red throated Caracara. They specialize in eating WASPS.


Want to learn more about the Octopus? Here is a great YouTube video that shows them doing some of the cool stuff they do (including tool use and squeezing through very small spaces). I don't recall any vulgarity in this video but the guy goes curse in some of these so you might want to listen with headphones if little kids are around.


I always love hearing about an animal I've never heard of before. This week it's the Trilobite Beetle


Gentlemen, prepare to feel inadequate. Did you know that snakes have TWO penises? 


On the Bad News Front a Nile Crocodile was captured in the Everglades. These Crocodiles are responsible for hundreds of human deaths in Africa each year. Compare this to the 0 - 2 people killed by Alligators and you can guess how this might be a problem if these Nile Crocodiles become established.


On the Good News Front California has banned the sale of rodenticies to the general population. This is great news for wildlife and pets. These rodent poisons take several days to kill  mice and rats and those dying animals are frequently caught and eaten by predators like bobcats, hawks, foxes and pet dogs and cats. When I was working in the LA area secondary rodenticide poisoning was causing a rash of fatalities in the local bobcat population. These rodenticides work by preventing blood clotting so the mice and rats (or whatever has eaten them) basically bleeds to death internally. Kind of like what Ebola virus does.

Weekend Reading - Spring Break Edition

Elephants are fucking amazing! They can distinguish between human languages, male and female voices and adult and child voices and react accordingly.

A company has made health claims about a new product. It cites publication, patents and patients. Can you trust this company? Turns out, no, you can't. The publications have nothing to do with their product, the patents are not for their product and the patients? Anonymous and they don't mention results in those patients. Advertiser lie.

Can you survive immersion in boiling water? How about liquid oxygen (-317 F)? Want to meet a Superhero that can?

Trilobites used to be one of the most common forms of life on the planet. Ever heard of them?

No that was not a Mountain Lion in Massachusetts

So it's not completely unheard of for Mountain Lions to be spotted in Massachusetts. One was hit by a car and killed in Connecticut just a few years ago (it had been born in South Dakota!). But color me skeptical about the latest sightings. Even the eye witnesses claimed they just saw it for a minute and when biologist looked at the tracks (footprints) they were shaped like a dog track and not like a cat (a trained tracker can tell the difference and it has nothing to do with visible claws).


In my experience lots of people WANT to see a Mountain Lion. For the thrill, the fame, the excitement. But very few people actually have seen these elusive cats. I've heard lots of descriptions by hopeful eyewitnesses that convinced me that nope, that wasn't a Mountain Lion.

Mountain Lions do not regularly occur East of the Rocky Mountains (except in South Florida). They were hunted out of their native ranges in the Eastern US when the Europeans settled North America. With the passage of the Endangered Species Act and improved protections the western populations have been increasing and we have seen some individuals move out of their existing range into new habitats. A great site for information about these cases is the Cougar Network. This site requires hard evidence before adding a claim to their site - evidence in the form of scat, hair, verifiable photographs and dead animals.

It's exciting (and scary) to think that this apex predator could be returning to some of its earlier range. While Mountain Lions can kill people these events are rare. They are a greater risk to farm animals and pets. Fortunately they require large spaces to roam so that even where they occur in their highest densities the likelihood of encountering one is very, very low.

And maybe between them and the coyotes they'll be able to keep the deer from eating my garden!

How long can you go without food. A couple days? A couple weeks? (a couple hours?) Here's the story of one animal that went on a hunger strike for 5 YEARS! Be sure to scroll down for the photo - you'll be shocked at the size of No. 1.

Forget sharks with lasers, I'm happy with sharks with video cameras giving us a sneak peak into their personal lives.

So I had a crazy-busy week and didn't get many links set up this week. To make up for it here is a fun link to a guide to pet dinosaurs.
