About GrrlScientist

grrlscientist is the pseudonym of an evolutionary biologist and ornithologist who writes about evolution, ethology, and ecology, especially in birds. After earning a degree in microbiology (thesis focus: virology) and working at the Fred Hutchinson Cancer Research Center in Seattle, she earned her PhD in zoology from the University of Washington in Seattle, where she studied the molecular correlates of testosterone and behaviour in white-crowned sparrows. She then worked a Chapman Postdoctoral Fellow at the American Museum of Natural History in New York City, where she studied the speciation and distribution of lories and other parrots throughout the South Pacific Islands. A discarded scientist, she returned to her roots: writing. Formerly hosted by The Guardian (UK), she now writes about science for Forbes and for the non-profit think tank, the Evolution Institute and she writes podcasts for BirdNote Radio. An avid lifelong birder and aviculturist, she lives with a flock of songbirds and parrots somewhere in Germany.

    There is a wild avocado tree on North Garfield Street in Alhambra, California. (The fruits are very small). When the fruits ripen, the ravens come for a feast. They will defend the tree, trying to drive off unwary pedestrians.
    In neighboring San Marino, I’ve seen ravens at a four-way-stop intersection dropping the acorns from live oaks onto crosswalks, but only on the right side of the road. Here is where cars go the slowest as they come to a stop, and then pull away, breaking the acorn hulls. Cars going over acorns at higher speed shatter them, so apparently ravens like their acorn meat chunky style, not creamy.
