Photo showing a bird perched on an apple tree branch. The apple tree is in bloom and has white flowers. The bird is a light brown, with a black mask above its beak, angling upwards at the eye and ending behind a short crest. Watermark identifying photographer as Geneviève Laurin.

"Sunny wings"
I came across a mob of Cedar Waxwings who seemed to be eating flower petals from this apple tree. Anyone know if this is a known behavior?

Turtles map seagrass better than satellites can Tracing tagged turtles reveals more than 30 new seagrass sites in the Red Sea

“… like underwater blood hounds, sea turtles that feed on seagrass can lead researchers to the meadows far more reliably than satellite images, a team of marine ecologists has found.”

Sequential appetite suppression by oral and visceral feedback to the brainstem - Nature Genetically distinct neural circuits in the caudal brainstem receive feedback from the mouth and gut to regulate feeding behaviour on short and long timescales.

🧠🍽️ ”Sequential negative feedback signals from the mouth and gut engage distinct circuits in the caudal brainstem, which in turn control elements of feeding behaviour operating on short and long timescales”

From the stomach to locus coeruleus: new neural substrate for ghrelin’s effects on ingestive, moti... Ghrelin, a stomach-derived orexigenic hormone, has a well-established role in energy homeostasis, food reward, and emotionality. Noradrenergic neurons of the locus coeruleus (LC) are known to play an ...

Ghrelin action in the PVH of male mice: accessibility, neuronal targets and CRH neurons activation Abstract. The hormone ghrelin displays several well-characterized functions, including some with pharmaceutical interest. The receptor for ghrelin, the growth h

"Plasma ghrelin can directly target a subset of nitric oxide -producing neurons of the paraventricular hypothalamus that is involved in ghrelin-induced activation of the hypothalamic-pituitary-adrenal neuroendocrine axis."
