Myiarchus flycatchers ordered by size and intensity of yellow underparts. When it comes to flycatchers, differences between species tend to be very subtle. Impressions of size and color in the field can be quite subjective, but the differences are real.

*Sigh*. Caught a grad student using AI to generate fake citations today. Need to figure out the best strategy to make this a teachable moment. Maybe "gentle teasing"? "Strict warning"? Unclear which will work best in this case.

Further, it allows a political appointee (usually not a scientist) to take disciplinary action against those seen as sharing misinformationâ based on their political determination. Basically, this is threat to scientists to draw conclusions consistent with the Administrationâs position.

Science and research should be objective. This Exec Order is a rant on science the Administration does not like. Following that it seems to promote good research practices (Sec.3, part a)- but alas⊠The EO gives a political appointee the power to decide when findings need to be âcorrected.â
