Hidden Hawaiian Bird Nests Finally Found

https://www.hakaimagazine.com/news/hidden-hawaiian-bird-nests-finally-found/?utm_source=Hakai+Magazine+Weekly&utm_campaign=5a04351bb3-EMAIL_CAMPAIGN_2017_09_06_COPY_02&utm_medium=email&utm_term=0_0fc1967411-5a04351bb3-121598265


Researcher Nicole Galase scoured the lava fields on the Island of Hawai?i in search of band-rumped storm petrels? nests. Scientists knew the birds frequented the air above the fields, but Galase was the first to locate their nests hidden within lava tubes, with the help of a sniffer dog, Makalani. For paw protection on the rough lava fields, Makalani wore booties. Photo by Nicole Galase

Ancient birds out of the egg running

https://www.sciencedaily.com/releases/2019/03/190321102826.htm?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+sciencedaily%2Fplants_animals%2Fbirds+%28Birds+News+--+ScienceDaily%29


Feathers revealed in a ~125 million-year-old fossil of a bird hatchling shows it came "out of the egg running". Specimen MPCM-LH-26189 from Los Hoyas, Spain is preserved between two slabs of rock: (a) 'counter' slab under normal light (b) Laser-Stimulated Fluorescence (LSF) image combining the results from both rock slabs. This reveals brown patches around the specimen that include clumps of elongate feathers associated with the neck and wings and a single long vaned feather associated with the left wing. (c) Normal light image of the main slab. Scale is 5mm.

Quote from "Respiratory and Heart Rates of Birds at Rest," William Calder, "The Condor," October 1968 (unavailable without $).

"Respiratory rates are increased to compensate for metabolic acidosis during formation of CaCO3 for egg shells (Mongin and Lacassagne, 1965)..."

From Wikipedia: "Metabolic acidosis is a condition that occurs when the body produces excessive quantities of acid or when the kidneys are not removing enough acid from the body. If unchecked, metabolic acidosis leads to acidemia, i.e., blood pH is low (less than 7.35) due to increased production of hydrogen ions by the body or the inability of the body to form bicarbonate (HCO3-) in the kidney. Respiratory compensation (hyperventilation) will cause more carbon dioxide to be removed from the body and thereby increase pH."

I was hoping to find research on a subject that came up in chat, namely, why is Mom panting in relatively cool temperatures? I assumed it was because of excess heat generated by incubation. The amateur sleuthing I did, above, suggests an additional explanation. Mom may still be recovering from laying 3 eggs. ???

In a first, fossil bird found with unlaid egg

https://relay.nationalgeographic.com/proxy/distribution/public/amp/science/2019/03/first-fossil-bird-with-unlaid-egg-found-enantiornithine?__twitter_impression=true


In this illustration, a colony of Avimaia schweitzerae nests on a lakeshore in what would become northwest China. Somehow, one female ended up dead in the water--eventually yielding the first fossil bird ever found with an unlaid egg inside.
