Selfie Sticks and Hummingbird Nests

We found another hummingbird nest in the Nature Gardens! On December 28th Miguel Ordeñana, Museum Citizen Science Coordinator, found an Allen's Hummingbird, Selasphorus sasin, nest in our cork oak tree.

As you can see she's (only female hummingbirds build nests and care for the young) sitting pretty in her nest, but are there any eggs? Over the last few weeks we've observed her sitting in the nest for extended periods of time. This behavior led us all to believe that there were definitely eggs in there. But, we wanted to be sure. As luck would have it, I recieved a late Christmas present last night–a selfie stick.

It was sort of a joke gift, I am a vocal selfie stick hater! I mean, I just can't...

First Lizard Found in Museum's Nature Gardens!

On November 19, 2014 something happened at work that I’ve been waiting three and half years for. Unfortunately, I wasn’t here to witness it, but thanks to citizen science I was able to celebrate the discovery, even though I was 6,187 miles away.

On that day, newly turned citizen scientist Toni Castillo documented the first lizard in the Museum’s Nature Gardens.

The lizard in question was a Western Fence Lizard, Sceleporus occidentalis, and Toni, a Museum staffer, just happened to see it as she was walking through the gardens.

“I was walking next to the Living Wall and saw something in the pathway. At first I thought it was a leaf or a stick, but then I looked closer and realized it was a lizard.”

Toni knew that this was a unique find—she’d heard...

We Found a Western Red Bat in the Nature Gardens: A Small Visitor with Big Implications

Happy bat week everybody—we have bat-tastic news to share with you just in time for Halloween!  Over the month of September we recorded not just one, but TWO new species of bats that had never before been detected in the Museum’s Nature Gardens. Firstly we found the non-migratory and somewhat urban-adapted canyon bat, Parastrellus hesperus. This bat is common throughout the southwest and is strongly associated with rocky crevices found in canyons. Because they roost in these dark places and are able to remain in the same location year-round, this may mean they can adapt to roosting in urban spaces in L.A.—anything from cracks in concrete underpasses to crevices on hillsides that are...

Nature's Tiniest Potters

Did you know there are small wasps here in Los Angeles that are potters? No, I don't mean some sort of weird waspish Harry Potter fan club—although that sounds like something I'd be totally into—I mean wasps that use mud to make miniature pots. Take a look at the craftsmanship, the sharply narrowed neck and that wide fluted rim, exquisite!

Photo taken by NHM Head Gardener Richard Hayden, with my fingertip for some perspective!

This "pot" was constructed by a small wasp (one of those solitary wasps that are not prone to stinging us humans), which entomologists call potter wasps. However, this wasp wasn't just being artistic, she constructed this pot for a purely utilitarian function—it is actually a nest for an egg!

A few weeks ago during a California Naturalist training, I spotted this...

Do you have Museum Malaise?

You better not! However, just in case you do I have a line of curative agents perfect for any and all afflicted with such exhibit ennui. The elixirs I speak of are our new L.A. nature exhibits, Nature Lab and Nature Gardens, and they're about to open on June 9!

I've written loads of posts about both exhibits, so I thought it might be interesting to have a guest writer this week (I swear it's not because I'm too busy)! Dean Pentcheff from our Research and Collections staff is going to answer the question that everyone will be asking when the Nature Gardens open, who's camping in that tent out there?

"Peek between the bushes in the Nature Garden and you’ll see what looks like someone’s overnight camping spot. We do host overnight sleepovers at NHM but we don’t do it in the garden (at least not yet). What’s going on here?
