The free app is by the Cornell Lab of Ornithology in Ithaca, NY. It uses eBird to figure out which bird you saw. eBird has a database of bird distributions and abundances in Canada and the United States. It’s a citizen-science project that started in 2002.
…which is why grey treefrogs are sometimes brown, grey, green, or something between.
There are two species of grey treefrogs in Manitoba: Cope’s grey treefrog (Hylachrysoscelis) and the grey treefrog (Hyla versicolor). The similarity in common names gives a clue that there isn’t much difference between the two species. They look the same, but can be distinguished by their call. Cope’s has a faster, higher pitched call than the grey treefrog.
The Worthy Beginner will feature posts each week that help you and me understand the wonderful world of science. Plants, animals, fungi, and everything in between will be discussed, as well as anything else with a science twist to it — economics, politics, music, and more.
What’s in a name anyway?
I took a critical thinking course at the University of Manitoba. One rule we learned was Ockham’s Razor by William of Ockham, which says when presented with multiple theories, accept the simplest one.
William of Ockham (c. 1287-1347) went to the University of Oxford in England but didn’t finish his degree, earning him the nickname “The Worthy Beginner”.
I can relate to William of Ockham. Though I finished my BSc, I don’t consider myself an expert in anything, nor do I think I ever will be. I’m interested in a lot — science, economics, politics, music, culture — and on a good day, I consider myself to be a worthy beginner.
