Saw a #ringbilledgull in Stockholm yesterday, bang in the middle of the city! There are only 14 or so records of this North American vagrant and it attracted quite the paparazzi! It was chilling with the other gulls, searching for food from humans, and harassing nearby pigeons. #gulls #birds

Animals can’t talk like humans do – here’s why the hunt for their languages has left us empty-handed
Many scientists see evidence of language in the sounds animals put together, but they may be kidding themselves.

Excited to share our new preprint! Unlike the North American yellow warblers, females in Galápagos commonly sing and duet with their paired partners. Here, we tested possible functions with a playback experiment: www.biorxiv.org/content/10.1...
 Illustration of female and male yellow warblers and their respective songs. On top, two duets are shown in spectrograms with male parts marked in red and female parts marked in yellow. On the left are three female songs and on the right are three different male songs. Illustrations are courtesy of Lena Gies.
