A four-panel comic titled "how to get into nature". In panel 1, a person kneels in the woods, looking down at a red-backed salamander, and the text says "notice a living thing." In panel 2, the text says "notice some other things that live near it," and there's a starflower, springtail, ant, little wood satyr butterfly, and salamander on the leaf litter. In panel 3, covered in creatures, plants, and a colorful starburst, the text says "Notice the connections between them, discover the wider ecosystem, learn about its histories, and find yourself following links from bedrock to stratosphere, between biotic and abiotic, at scales both microbial and massive, until you’re hopelessly overwhelmed by the wonder of it all." In panel 4, the text says "Fall into a daze and let moss engulf you." The person from the first panel is still kneeling in the woods, looking happy as moss slowly engulfs them, and they're saying "This is for the best."

How to get into nature.

A flock of 19 little pied cormorants (Microcarbo melanoleucos) flying in a flock towards their evening roost on a quite windy and overcast day.

Little pied cormorants coming in to roost at the end of the day. I’ve watched them fly this path so many times, but I don’t often get this many on skytrap all in frame at once!

A green wildlife camera pointing at the sky adjacent to a solar panel that is powering it.

First light on a solar/battery powered skytrap! No shortage of sunlight in FNQ for testing.

A day photo from my sky camera, mounted on the house roof, showing the flight path trail a raven took as it flew over the house. The raven is seen in black as it makes a loop. The sky is a pale blue color and there are some tree tops in the bottom left corner and just a hint of a tree top nearing the center bottom of the frame.

I was hoping to get images like this from Sky cam, a raven was flying over the house and this is the flight path it took.

That’s fantastic! What sort of camera and exposure is getting such clear night shots?

And while I've got cockatiels on my mind, here's another photo, taken in my friend's backyard.

‘Sex reversal’ is surprisingly common in birds, new study suggests Survey of five Australian avians finds numerous discordant individuals, including a genetically male bird that had laid an egg

Sex-reversal in birds (genetically male/female but appear female/male) is surprisingly common. Best detail: A genetically male bird called a laughing kookaburra had recently laid an egg. (1/2)

A sequence of silhouettes of a Little Corella flying extracted from a video. Video taken from beneath the bird by a skytrap bird camera trap.

Silhouettes of a Little Corella motion tracked past a skytrap. In this moment, this individual is flying with a wingbeat frequency of 4.5Hz - pretty close to expected scaling for a bird of that mass!

Linking individual animal behavior to species range shifts under climate change Climate change has led animal species to shift their ranges to greater elevations, latitudes, and depths, tracking their preferred abiotic niche. Howe…

The first paper from my postdoc is finally out! In collaboration with @kaitlyngaynor.bsky.social and Amy Angert, we outline how behavioral plasticity influences animal species’ distributions and can improve our understanding of range shifts under climate change! www.sciencedirect.com/science/arti...

I've been on attenuation models for some time, and it is always nice (and hard) to write papers between physics and ecology. I have actually developed a new attenuation model for this one! Have been working with physicists on a second paper using birds from Amazonia.❤️ To be continued!

Red Wattlebird landing next to skytrap 5. If Silver Gulls are my most trapped species, this is one of my most trapped individuals. Slowed to about 20%.

Birds are dinosaurs who shrugged off a couple apocalypses. Some eat bone marrow. Some drink nectar. They outswim fish in the sea. They smile politely at gravity’s demands. ‬

‪I am grateful to see them. I am grateful to feed them. I am grateful to know them.‬

Book cover for a book called "Bear to the Rescue" by Romane Cristescu and Nic Gill, Illustrated by Sylvia Morris. Book cover shows watercolour image of a smiling, blue-eyed, grey and white dog wearing a blue jacket and black and red protective boots, standing in front of a burnt out etree with a koala and her joey sheltering in the uppermost branches. The background air is a pinkish colour, and there are dead yellow leaves scattered on the ground, but the overall impression is one of hope.

🚨Arooga arooga! 🚨

Excited to share the cover of my very first picture book: "Bear to the Rescue"! 🐨🐶📘🔥

Co-written with Romane Cristescu, and illustrated bySylvia Morris, our book tells the true story of Bear as he goes from being a bit "too much" to saving koalas after the 2020 mega fires 🔥

Research findings:
💩 #Shearwater guano is rich in phosphorous & potassium
🌴There is evidence the #birds "fertilized" the soil
🐧 Many seabirds are in decline, including LHI's shearwaters
💩 Islands experience a reduction in nutrients from “lost” guano
🌴Likely results in vegetation changes over time

1. Here's a fish swimming upstream. Nothing unusual about that.

What's unusual is that this particular fish is *dead*. Vortices in the water as it flows past the fish cause the fish's body to flex, maintaining orientation and actually propelling it forward.

No, it's not a sulphur-crested cockatoo, but it is a clever cockie!

Masters student Miro van den Berg is using light-weight BLE-tags to study the urban lives of the gorgeous gang-gang cockatoo. You can read more here: sites.google.com/site/lucymap...
