Ph.D. Student in #Urban #Evolutionary #Ecology in Paris. Changing feather coloration of both great and blue tits in urban contexts. 🐦‍⬛

[Nicolas Bekka @Nicolas_Bekka]

New paper out in @AnimalEcology! 🔥🕺💃🔥

Across 6 European cities, great tits breeding in more impervious territories had paler carotenoid-based yellow plumage! 🐦‍⬛🏙️

Huge thanks to everyone involved in long-term monitoring who made this possible!

[Journal of Animal Ecology @AnimalEcology]

This study provides the first continent-scale evidence that carotenoid-based colouration declines along a continuous urbanisation gradient 🏢 🐦‍⬛ 🌍

Happy to share a #NEWPAPER unveiling how the Blue tit species interprets dominance cues (like tie size) from the Great tit, ultimately benefiting itself. A groundbreaking discovery of interspecies signalling I'm proud to have contributed to! @museuciencies

Great tit songs are transmitted from generation to generation through learning, often with remarkable accuracy! But what if their learning abilities could be disrupted by pollution? a 🧵 1/6

Delving into the impact of urban bird feeding in Europe, I explore its influence on bird evolution, focusing on great tits and blue tits in Innsbruck, Austria.

1/6 #BOU24 #SESH5: There is impetus to build more houses, but recognition this can’t come at a loss to biodiversity. That’s why governments globally are implementing laws stating that “new builds” should not result in a loss in wildlife. But there’s still the question of how?

[Dan Chamberlain @DanC_eco]

1/13 #BOU2024 #SESH5
As the global human population increases, so does the proportion that lives in urban areas. This will inevitably lead to larger and/or denser cities, and likely increased environmental impacts of urbanization.

Today I’m presenting part of my PhD research at the #BOU2024! 🐦Join me in the following thread as I’m looking into infectious hotspots and prevalence rates in the urban landscape.

Amazing talk on the most fascinating subject in urban ecology => coloration variations of birds in cities! 🐦‍⬛

#BOU2024 #SESH3 1/6 Urbanisation and climate both create novel environments and shape phenotypes. With the urban heat island, urban areas can provide insights into future climate changes. However, the interaction between urbanisation and climate has not been investigated yet.

[Juan Carlos Senar @SenarJC]

1/6 #BOU2024 #SESH3. In recent years, it has been found that birds from urban environments have shorter wings than those from forest. However, the key is to determine whether these changes result from plastic responses or adaptive evolution. #ornithology #museuciencies

#BOU2024 #Sesh3 6/6: European Project: Across Europe, urban tits wear paler plumage. But study sites differ. Disparities in intensity of urbanisation between cities may explain these differences, and I launched a European collaboration to explore this. 🌍🔬

#BOU2024 #Sesh3 1/6: Urban Challenges: Urbanization profoundly alters the biotic and abiotic conditions shaping city bird lives. New urban challenges impact their phenotypes. 🏙️🦜
