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.

    I have a pin oak and it was planted 6 years ago in my back yard. The leaves are yellowish with brown spots on them. Last year they had me put Bayer liquid fertilizer that you mixrd with water and it was good for a year. This year I got another oppinion and he had me put ironite down because of no green and was in acidic soil. He said this will green it up. It gets plenty of water since I have in ground irrigation system in place. I just layed the ironite down 1 week ago. Thought I would write to get another oppinion.
