@pnwkate @DiscoverSurrey Looks pretty good for Goshawk to me - powerfully built, white supercilium, uneven tail banding, pointy wings. Cooper's Hawks are crow sized; Goshawks are closer to Red-tailed Hawk.

@IBchemmilam I guess if you had a well-calibrated bathroom scale (used for measuring humans) that reads to the nearest kg, and you repeatedly measured a 2.0000 kg mass on it, it would be high accuracy but low precision. It doesn't translate to the bullseye picture, though...?

[H de G @chiral_guy]

@IBchemmilam Also, the "low precision, high accuracy" condition feels really contrived, especially using the same number of data points as the other examples.

@loosemum @TheIneptBirder Blue feathers (such as on Indigo Buntings or Blue Jays) get their color from light bending (refraction) and interference (diffraction), not from blue pigments. There are blue pigments found in some plants, like indigo and cyanidin. https://t.co/9PxAxyLdVj

This was the best 90 seconds of my day so far!

@4letterbird Last summer in South Africa I saw an African Scops-Owl and then later THREE Verreaux's Eagle-Owls in the same day. My kids almost lost their minds, and honestly it was one of the best days of my life.

@UrsulaV Ordered! Thanks for writing it!

@chschemcrazy "95% of students having an A or B in all classes" feels like a proxy for 95% of students are engaged & working hard - not a bad thing, right? Maybe it's way to quantify other things that are harder to measure (e.g. engagement). My school isn't typical, but we meet this threshold.
