'Tis the Season for Baby Lizards

Over the last few weeks, baby lizards have been hatching out of their eggs throughout Southern California. Most of these baby lizards are one of two widespread species, the Western Fence Lizard and the Side-blotched Lizard, but it is also hatching season for many of Southern California’s other lizard species.



Father and son citizen scientists Drew and Jude Ready observed a baby Western Fence Lizard in Claremont on June 30th. Jude carefully picked up the tiny lizard, while Drew took a photo that he then submitted to the Reptiles and Amphibians of Southern California (RASCals) citizen science project....

The Midday Sunflower Long-Horned Bee Huddle

The life of the bee as we often think of it is one of constant motion: buzzing, dancing, collecting, feeding, searching, and digging is all in a days work for the “busy bee.”  What many may not realize is that this perception of the bee is mainly from our frequent encounters with the females of the species which must not only feed themselves but also take care of their young.  Honeybees, which are highly unusual in their behavior compared to most bees, have workers that are specialized in gathering pollen and communicating its location through dance, building and cleaning the waxy hive, and taking care of their larval sisters. The vast majority of bee species, unlike the honeybee, are solitary: One female alone must take care of her young; there is no queen or workers to do all the grunt work.

Walnuts, anyone?


by Carol BornsteinPhoto by Carol Bornstein

Squirrels and humans have something in common – both love nuts. If you skip the added salt and oil, these tasty “fruits” are good for you, too. And if you are interested in foraging – with permission and proper identification, of course - several of California’s native trees and shrubs offer up some mighty flavorful nuts. Just ask the squirrels!

For centuries, Native American tribes throughout California have harvested native hazelnuts, pine nuts, and walnuts. Birds, squirrels, and other wildlife also feast upon these nutritious foods. Here in the Los Angeles Basin, southern California black walnuts (Juglans californica) are still relatively easy to find in the Santa Monica Mountains, growing among coast live oak, toyon, elderberry, sycamore, and other...

Arroyo #Chubwatch 2015

After three long years of planning, 45 arroyo chub were finally released into the Nature Garden's pond last week. 
Arroyo chub (it's alive, don't worry!) held for a quick photo op before release into the pond! Photo by Richard Hayden.

Arroyo chub, Gila orcuttii, are a native freshwater minnow found only in the coastal streams of Southern California, says Chris Thacker, Museum Curator of Ichthyology (fishes). They are classified as threatened in this native range and are noticeably missing from the lower reaches of the Los Angeles river. So, when it came time to think about fish in the Nature Gardens pond, all our scientists and educators wanted Arroyo chub.

 
The chub were transported from the...

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.
