Museum Makes Room for Nesting Cliff Swallows

Cliff swallows have moved onto, rather than into the Museum! Last week, Kimball Garrett, Museum bird expert, reported finding a nest under the eaves of the building directly facing the historic LA Memorial Coliseum. As he got close enough to snap this photograph, Kimball observed a pair of young swallows peering out of their finely crafted mud dwelling.

Check out that architecture! The adult breeding pair work together to collect mud pellets from the immediate area and use their bills to transport and mold them into a viable nest.  

Cliff swallows, Petrochelidon pyrrhonota, have historically nested on our building–back in the 80s and 90s Kimball would see them every year–but recently they have been noticeably absent. We are not sure what has caused them to return, but we're definitely tracking their progress and hope they...

Rare Nine-spotted Ladybug Found in L.A.!

During Bug Fair, I found a ladybug in the Museum’s Nature Gardens, that didn’t look familiar. It didn’t have any spots, but it somehow looked different than all the other no-spotted ladybugs I’d seen before. I took its photo, posted it to our Nature Gardens Survey on iNaturalist, and then totally forgot about it.

It wasn’t until a few weeks later, while I was preparing for a behind-the-scenes tour in entomology that something made me come back to that photograph. I was planning to talk about a big discovery made by a citizen scientist back in 2009—the time Harsi Parker discovered a rare nine-...

Lizard Love Bites

Have you recently seen lizards in L.A. that appear to be biting each other, or maybe they are trying to eat each other? 

If you have, you are not alone. Citizen scientist, Diana Beardsley, saw these two in her lizard-filled backyard and sent us this picture. It became the latest data point in our Reptiles and Amphibians of Southern California project (RASCals) which helps us understand the state of urban lizard populations. It also helped us realize a pattern!

Diana was not the only one to send us a picture of one lizard biting another. Many of the people who sent us these pictures were not sure exactly what they were witnessing–were they fighting, trying to eat each other, or doing something else...

The Flight of Monarch Butterfly 64365

Somewhere in L.A. a monarch egg hatched and out popped a tiny girl caterpillar. That caterpillar ate, and ate, and ate. She ate milkweed, the only plant she could, until she molted her skin. All told, she molted four times until she was a big, fat, stripy caterpillar with black tentacles. She made one last molt and formed a bright green chrysalis with shining golden spots. Two weeks later she emerged from that chrysalis as an adult, and then she flew. On November 17, 2014 she was spotted in the Museum’s Nature Gardens. She was caught in a net, and gently removed by skilled hands. A small, circular, paper sticker was affixed to her hind wing with the numbers 64365 printed on it. She was released and flew off into the distance. We knew there was a good chance that we’d never see her again.

Ankle Bracelets for House Sparrows

Last week, husband and wife ornithologist team Kimball Garrett (Museum ornithology collections manager) and Kathy Molina (Museum Research Associate) partnered with citizen science staff to band house sparrows (Passer domesticus). We hope that by banding these birds, we'll be able to understand how they use our urban environment. These little brown birds are literally everywhere, yet not much is known about their local behavior.  What we do know is that they are originally from Europe and were purposefully introduced to North America starting in the 1850s. Because they are very adaptable in both urban and rural areas, their numbers have since exploded. You might recognize them as the bird that once stole your French fries!

Kimball wants to know more, "do they spend all day feeding and socializing in our Nature Gardens or do some have lunch at the...

Purple Pollen Eaters: A Honey bee's Love Affair with Phacelia

Spring is here and everyone is totally digging the wildflower display in our Nature Gardens. Casey Schreiner from Modern Hiker even gave us a shoutout on Instagram

It's a good day for #wildflowers at the @nhmla!

The two flowers vying for your attention in this photo are, according to Carol Bornstein Nature Gardens Director and native plant guru, "the white-tipped yellow blossoms of tidy tips, Layia platyglossa, and tansy leaf phacelia, Phacelia tanacetifolia." Carol goes on to explain, "the nectar-rich, sweetly scented purple flowers of this taller annual are attracting droves of bees."  Boy is this true.

Kid Citizen Scientist Finds First Snail for Project S.L.I.M.E.

A few weekends ago, citizen scientists from all over L.A. came to the Museum to see what they could find hiding in the damp and cool shadows of our Nature Gardens. Twenty people joined Museum experts (Lindsey Groves and Florence Nishida) to search for slugs, snails, and fungi—those often overlooked decomposers that break down dead and decaying material. They were also the first people to test out our latest and greatest citizen science project, S.L.I.M.E. (Snails and Slugs Living in Metropolitan Environments). Within ten minutes, one of our youngest citizen scientists made the first S.L.I.M.E. discovery - a glass snail (Oxychilus draparnaudi) in the Pollinator Garden.



Check out what else we found:

115th Annual Christmas Bird Count @NHMLA!

On December 28, everyday people from all over Los Angeles flocked to the Natural History Museum to help count the bird life of L.A.! Some came as beginners ready for an intro to birding from Kimball Garrett, one of the best and most well-known birders in town, who also happens to be the Museum’s Ornithology Collections Manager. Others came because they were interested in contributing to this important bird census, but didn’t plan to see any surprising or remarkable species in our small urban oasis.  Little did they know they were in for some surprises.


Kimball started off the morning explaining what the Christmas Bird Count (CBC) is all about. He hyped up the activity by reminding everyone that it is the oldest citizen science survey in the world and provides invaluable information on bird population trends.  Another fun fact that Kimball...

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...
