A watercolor painting of a Turkey vulture. The painting has no background and is focused on the animal. It is perched with wings held out as if sun bathing. Its body is facing away with its head turned to face the viewer.

I've been hired by @birdsoftheworld.bsky.social as an illustrator through the Bartels program and I couldn't be more excited to start! This has been a dream of mine for years.

My Turkey vulture has been finished for a while so I am finally sharing that too! 🐡🪶🎨 #BirdArt

I am making a Starter Pack for people who are looking for PHD STUDENT POSITIONS in the biological sciences! If you wish to be added, please respond directly to this post saying you want to be added. I need at least 5 people to create the pack. Please share widely!

Photograph of an Eastern Whip-poor-will that is roosting during the day on a horizontal branch near the ground. The bird is an oddball-looking fellow, with a big flat head and a tiny bill that you can barely see. Its feathers are a mix of brindled brown and gray, which creates excellent camouflage with tree bark and leaf litter. In the photo, the bird is in profile, facing to the left, with a couple of bright green plants in the foreground and a small tree trunk and various green blurs in the background.

Since the start of 2024, I have managed to photograph 8 of the 9 nightjar species that regularly occur in the USA. 🪶

Here is my 1st ever photo of an Eastern Whip-poor-will that was found day-roosting at Magee Marsh Wildlife Area this past May.

I've been looking for a Least Bittern for months, and last weekend I was treated to see one flying around. Last year I saw one for the first time that year on July 5th. This year, it was again July 5th for my first Least Bittern of the year. It's a lucky Least Bittern day 🍀

Re-upping this: If you are an ornithologist (ideally U.S.-based) who uses bird banding or BBS data in your work, I'd love to hear from you! You could comment as something like "a scientist from a state university" (for example) if you don't want to use your name.

You mean I’m supposed to work when there are birds out there who aren’t being watched?

Very cool! Good luck with your field season

That's exciting, congrats! What frog species are you recording for / what will the recordings be used for? (Big question, I know! 😅)

A gnatcatcher nest hidden in the y-branch of a tree. It is a small cup nest made of moss and a gnatcatcher peaks out from where it sits on the nest

I ran into a pair of blue-gray gnatcatchers that seemed even angrier than usual. Made sense when I spotted their nest well hidden above me! 🪶

Amazing 😂 I love them so much

Woman Reminds Self Not To Catastrophize After Spotting 4 Skeletal Horsemen On Horizon LOWELL, MA—Doing her best to follow her therapist’s advice for dealing with stressful situations, area woman Holly Debling reportedly reminded herself Tuesday not to catastrophize after she spotted four skeletal horsemen on the horizon. “Okay, Holly, remember: Just because a great trumpet has sounded at the arrival of four unearthly riders, that doesn’t necessarily mean […]

The front of a Cap'n Crunch's Oops! All Berries box, but it is edited to instead say "Oops! All Juncos" and instead of the captain's face there is a hastily edited picture of a Dark-eyed Junco, with a dark gray head, black eye, and pink beak. There is also a hastily edited photo of a junco in flight, showing off their white belly and white tail-edges.
