New #AustralEcology paper on bird/ectosymbiont relationships: the presence of ectoparasites relates to worse flight muscle condition. Vane-dwelling feather mites are more likely commensals. @EcolSocAus@wileyecology https://t.co/zu69ahYAWo

Hello fellow bird nerds! ๐ฆ๐ฆ๐ฆ๐ฆ ๐ฆข๐๐ฆฉFor those of you still catching up on all of the wonderful content from #AnimBehav2021, I have assembled a thread of all of the avian research from the past two days (sorry not sorry icthyologists #birdsvsfish)
@BirdSongLab1 @cowbirdlab Thanks! Well, I'm now working on the sexual display of lekking birds, more focused on gestural traits. But bird song will always have a place here! Let's stay in touch!
1. Many birds defend territories by producing costly behaviors, such as vocalizations and aggressive interactions. Such behaviors are associated with the exclusivity of resources use in territories, which may enhance individual survivor and reproduction #AnimBehav2021
@_Marc_Gilles That is a great question! We still know little about this species and I have never seen studies on assortative mating concerning its song.
@ashleyrrobart Thanks for the question. It was only for females. We didn't find any relationships between male vocal properties and territory attributes.
@cowbirdlab Probably yes. Beak movements (which depends on its size/weight) seems to be related to frequency modulation and could affect trill production.
6. Our study provides new information for Parulidae in the Atlantic Forest. We encourage studies on territoriality and on the function of each element of male songs. We also highlight female role in territories defense, which has been historically neglected #AnimBehav2021
5. Females with broader frequency bandwidth in their songs occupy smaller territories, which indicates a possible role in territory defense. Female territoriality seems to be more common than thought, especially in tropical systems, favored by resources abundance #AnimBehav2021
@LilianManica@laschaedler Thanks Lilian! Yes, for smaller species we found that ants tend to be lighter (less melanized) in areas with higher temperatures, as predicted by the TMH.
1 Thermal Melanism (TMH) and Photo-Protection (PPH) are the main traditional hypotheses that explain the geographical variation of color in terrestrial ectotherms, due to the effects of thermoregulation and UV-B radiation, respectively #AnimBehav2021
