SHE DID IT AGAIN! Wisdom, the world’s oldest known wild bird, is back with a new partner and just laid yet another egg. At an approximate age of 74, the queen of seabirds returned to Midway Atoll National Wildlife Refuge last week and began interacting with a male.

I've enjoyed an inspiring visit to @michiganstateu these last two days, talking about vocal learning in sparrows, and sharing ideas about biology and ornithology. Thank you @mcgrawlabmsu and your great department!

New project on wren feather colour 🪶🎨🐦🇨🇷🇨🇦 with Dan Mennill @DMennill and a collaboration with Stephanie Doucet. More updates soon!

Happy to be back @UWindsor to analyze colours in wrens. A new collaborative project with Dr. Doucet @steph_doucet in our lab @DMennill Friends and colleagues in the lab make this time even nicer. 🎨🐦‍⬛🇨🇷🇨🇦

“Every window makes a difference, if it’s a window that kills a bird.” A reporter from @TheWindsorStar found a window-killed migratory bird. He reached out to chat about window kills. Check it out: https://t.co/qZu5MTX6i1

This study was led by me in collaboration with wonderful coauthors @IsabelVargasCR, María José Espejo-Uribe @Jose_lafina13, and with my postdoc supervisor @DMennill Financial support @NSERC_CRSNG @AnimBehSociety @gdfcf_org Read our paper here: https://t.co/Wmp6fkFxfs (5/5)

Song-type switching was not affected by the local density, contrary to what we originally expected. Local density modify the vocal behavior or birds (4/5)

Males sang at higher rates when the local density increased. Females showed a similar pattern in singing rate. However, the effect was marginal. Duet rate did no change. Local density modify the vocal behavior of birds (3/5)

We used an innovative experimental design to increase the apparent local density of conspecific territorial neighbors using programable speakers in the field. Wren illustrations by Caleb Sequeira-Ulate (2/5)

The Birdsong Lab at the University of Lethbridge is seeking 1-2 motivated graduate students to join us starting in Fall 2025. Funding is available. (a🧵1 /6)

Thank you @ICOMVIS for the invitation to share my postdoc research in the 40th Anniversary Celebration! Happy to meet with old and new friends and colleagues 🇨🇷🇨🇦🎶🦜🐦‍⬛🦉

Hot off the press: "Hormones and Reproduction of Vertebrates: Amphibians" edited by David Morris and Kristin Lopez. 🔥📙🐸 I'm excited that they selected my photo of Neotropical Yellow Toads for the cover! I took this photo in the biodiverse dry forests of Guanacaste Costa Rica.

Solo cortaron 24 palos dijo aquel mentiroso.

Previous studies estimating bird deaths from building typically only involved carcass counts. But new research taking into account subsequent deaths in rehabilitation centers reveals that more birds may be dying in the days following a strike.
