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...

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...

North Campus DIY

This week I've been working with Jared Nielsen, one of the Museum's Exhibit Technicians, who also happens to be a DIY (Do it Yourself) enthusiast. With his help we've managed to build and install two nest boxes and launch our first garden surveillance balloon!

The nest boxes we chose are made of PVC and designed to be particularly appealing to certain cavity nesting birds such as Western Bluebirds, Sialia mexicana.  These birds have been spotted in Exposition Park by Kimball Garrett, the Museum's resident ornithologist, and we hope they'll stick around to use our new nesting sites. The boxes...
