Blooming Agaves

More plant news from the North Campus. Recently some of our blue lotus agaves, Agave ceslii 'Nova', have begun to bloom. This is an impressive sight as these plants send forth long spikes, (between four and six feet long), that look a lot like giant asparagus stalks. This type of agave is monocarpic, meaning that it only flowers once, and this particular selection happens to flower at a relatively young age compared to other species. Incidentally, the genus is commonly called century plant because it can take decades for them to flower. The entire stand of this agave (approximately eight plants) is flowering at the same time, because they were all propagated from the same tissue culture, which is a common nursery practice for certain landscape plants. Although flowering signals the end of the plant's lifespan, we can expect to enjoy the flowers and fruits for the next several months!

Hummingbirds: Born to be Sword Swallowers!

We've got more bird babies at the Page Museum (you know the one at the La Brea Tar Pits)! We were informed about an Allen's Hummingbird, Selasphorus sasin, nest in the atrium about two weeks ago, and jammed over to scope out the scene. When we arrived we found two tiny eggs in a beautifully crafted nest, suspended about ten feet up in one of the plants.

This past weekend Sam Easterson captured the footage below. I really like the way you can see the nest stretch as the nestlings move around. This is because the nest is partially constructed from spider webs! When constructing the nest, the female hummingbird collects materials such as plant fibers, moss, lichen, and small bits of bark or leaves. She also collects the spider silk for its elasticity. As the nestlings hatch and grow the nest can stretch with them! Check out the video to see it and then be wowed with feeding time. The first time I watched this footage, I couldn't help thinking about a sword...
