Spring Babies in the Nature Lab

There are only 17 days left until our Nature Gardens and Nature Lab exhibits open! This makes me extremely excited and a little bit nauseous. To cope with the craziness, all I have to do is go and visit  our new Nature Lab babies. Just in case you're feeling stressed out too, here's some baby love for you:

This is our new program opossum, Didelphis virginiana. She is a rescue animal that we were lucky enough to get from a local rehabber. She is blind in one eye (from a dog attack) which makes her unreleasable, and therefore our newest and cutest ambassador for L.A. wildlife.

 
Look she smiles, even though she's blind in one eye!
 
We also have 14 baby Norway rats, Rattus norvigicus! They are currently in training to move into...

Black Rats, Brown Rats, and the Plague

I've been spending a lot of time thinking about rats. Thankfully, it is not because I have a problem in my apartment! Unfortunately, for many people in L.A., rats are a serious pest, and it's not just one type of rat. The most serious rodent offenders in our cities are the brown (aka Norway) rat, Rattus norvegicus, and the black rat, Rattus rattus.
 

What species of rat is this?


Here on the North Campus we have camera trap images and footage of rats hanging out underneath the bridge. But what type of rat is this? Since Jim Dines, our Mammalogy Collections Manager, wasn't available, I decided to try and figure it out myself. Doing a Wikipedia search for brown rats, I came across a nice diagram that helped me to make an identification. What species do you think it is?
