I started working with Alaska Dept Fish & Game to surgically place trackers in emperor geese in 2019. Since then, we've implanted 189 over 8 different trips, mostly to remote areas with no electricity. It's been a fun challenge with a lot of hard work by many people. Our survival rates have been phenomenal. The data collected has already taught biologists a lot about this remote species, helping to make informed decisions for conservation and for management of an important food resource for Alaska natives. Slowly, the transmitters that were designed to last 18-24 months are starting to blink off after almost 4 years of faithful service. Seeing those dots on a map, moving around, living their lives has been really cool. It's a little sad to lose touch but they've more than "earned" the chance to live the rest of their lives in privacy and peace, swallowed up in a vast wilderness where they rarely see humans. Good luck to them!

it occurs to me that the birds' experience of me may be drastically different from my experience. at least one of them has dived at my head twice

Humans have been eating clams for a long, long time. Stone tools dating to 125,000 years ago have been found among oyster and giant clam shells bordering the Red Sea, remnants of early migrations from Africa. And before that, Homo erectus is thought to have often hit up the raw bar, based on middens of shells they left behind! 🦪 #clamFacts

short and sweet episode. I've heard the word "perovskite", but the difference in cost is a real leap

This morning, a bit less than two hours in the Ramble yielded 33 species. Nothing new--I missed the reported Spotted Sandpiper--but I did see my first Ovenbird and Common Yellowthroat of the year (I had only heard them singing before).

A late-afternoon stroll in Carl Schurz Park had my first Barn Swallows of the year, around their usual nest site at the ferry dock. Only two so far, but that will pick up.

At least 20 Double-crested Cormorants nests on Mill Rock, with 44 birds.

I was today years old when I learned that there may be a relationship between pollen counts and viral respiratory infections. Pollen impairs the immune response to viruses, and viruses may also be able to hitchhike deep into the airways on pollen grains. High pollen concentrations in March 2020 may have facilitated the spread of COVID during the first pandemic wave 🤧 :virus:

Our #JWST rocky exoplanet team is back with a new result:

Water Vapor in the data of warm rocky planet! 💦

But is it from the planet's atmosphere or cool star spots on the star?? 🌎 🤔 🔴

Happy birthday to #neurologist Santiago Ramón y Cajal (1852 - 1934), here in front of Purkinje and granule cells from a pigeon, based on one of his own drawings! Cajal &Golgi won the Nobel in 1906, "in recognition of their work on the structure of the nervous system". He was as much of an artist as he was a scientist & his 100s of drawings are still used for teaching purposes.⁠

why does everyone seem to have such a defeatist additude about their data being harvested by apps and websites? i always hear people say how "it's probably all out there anyway" or "there's no way to completely prevent it, so i'm not going to bother partially preventing it", the more companies and organizations that spy on you, the more likely you'll be part of a data breach in which some personal information could be released about you. it's good to minimize your online footprint as much as possible.

I can confirm that they're roosting above my door. I stepped out to put my trash in the bin last night and peeked one of them there. before I'd see one in the nest and one nestled in these little plastic needles (which I think are supposed to deter birds🤔), but I only definitely saw one last night
