You’ll ask: And where are the lilies?
And the metaphysics covered with poppies?
And the rain that frequently hit your words
filling them with holes and birds

I’ll tell you all that happens to me.

I lived in a neighborhood of Madrid,
with bells, with watches, with trees.

I’m on a Twitter strike. I am so sick of the way men on Twitter treat women. And my male friends always DM me or text me or email me or talk to me about how they hate it too but they never speak up.

Let me be perfectly clear - this has nothing to do with the “women aren’t funny” argument. I am…

A team of Yale evolutionary ornithologists has drawn the first complete family tree for all known modern bird species, demonstrating an important and controversial new idea about biodiversity. Joe Hanson explains:

It was thought that any given species would expand and diversify quickly into subspecies (like the many different kinds of honeybees), soon maxing out its environment and filling all the ecological “niches”. Then, competition over limited resources would thin that down to the few most adaptable species. This tree says the opposite, that birds are continuing to diversify even today, and fast.
The center of this tree, anchoring branches built using fossil and DNA sequence data, reaches back nearly 50 million years, to the earliest days of birds branching off of dinosaurs.

In 1886, Los Angeles’ first high school moved across the street from Poundcake Hill to clear space for a new county courthouse.

L.A. as Subject explains in “The Lost Hills of Downtown Los Angeles” at KCET.org:

Civic leaders had initially planned to move the original Los Angeles High School several blocks from Poundcake Hill to Fort Moore Hill. A contractor who claimed he could accomplish the task hoisted the building onto scaffolding and, using rollers, horses, and human labor, slowly moved the schoolhouse toward its new location. After work was underway, the contractor decided that the task was impossible after all. The building remained where his crew left it, repurposed as a schoolhouse for younger students while a new, grander high school was built atop Fort Moore Hill.
