BehaveAI can now measure orientation. So now you can work out the behaviour of your animal in each frame as well as its direction - e.g. tells you which way animals are pointing or whether they're turning. Video guide: youtu.be/FgmtHoardWg Install: github.com/troscianko/B...

New bowerbird paper out, we asked whether male great bowerbirds care about the light environment around the bower where they display to females. Short answer: not really. What they do care about is having a display arena with strong visual contrast on the ground. 🐦 tinyurl.com/2v7rycdz
A u shaped structure made out of sticks called a bower, built under a small tree. In front of the bower is a pile of grey, white and green objects that make up the display court. The whole scene is in dappled sunlight and shade created by the tree above.

The DOGE firings have nothing to do with “efficiency” or “cutting waste.” They’re a direct push to weaken federal agencies perceived as liberal. This was evident from the start, and now the data confirms it: targeted agencies overwhelmingly those seen as more left-leaning. 🧵⬇️
Scatterplot titled “Empirical Evidence of Ideological Targeting in Federal Layoffs: Agencies seen as liberal are significantly more likely to face DOGE layoffs.”
	•	The x-axis represents Perceived Ideological Leaning of federal agencies, ranging from -2 (Most Liberal) to +2 (Most Conservative), based on survey responses from over 1,500 federal executives.
	•	The y-axis shows Agency Size (Number of Staff) on a logarithmic scale from 1,000 to 1,000,000.

Each point represents a federal agency:
	•	Red dots indicate agencies that experienced DOGE layoffs.
	•	Gray dots indicate agencies with no layoffs.

Key Observations:
	•	Liberal-leaning agencies (left side of the plot) are disproportionately represented among red dots, indicating higher layoff rates.
	•	Notable targeted agencies include:
	•	HHS (Health & Human Services)
	•	EPA (Environmental Protection Agency)
	•	NIH (National Institutes of Health)
	•	CFPB (Consumer Financial Protection Bureau)
	•	Dept. of Education
	•	USAID (U.S. Agency for International Development)
	•	The National Nuclear Security Administration (DOE), despite its conservative leaning (+1 on the scale), is an exception among targeted agencies.
	•	A notable outlier: the Department of Veterans Affairs (moderately conservative) also faced layoffs despite its size.

Takeaway:

The figure visually demonstrates that DOGE layoffs disproportionately targeted liberal-leaning agencies, supporting claims of ideological bias. The pattern reveals that layoffs were not driven by agency size or budget alone but were strongly associated with perceived ideology.

Firings are happening right now at the National Science Foundation. Essential staff are being cut. This isn’t about the budget. If it was, they’d be going after the military (17%) or state appropriations (38%). NSF is 0.7% of the federal budget. All federal employees make up only 4% of the budget.
