Foraging ecology and flocking behavior of insectivorous forest birds inform management of Andean silvopastures for conservation

http://www.americanornithologypubs.org/doi/full/10.1650/CONDOR-18-1.1


Tree species preferences of insectivorous forest birds in forest fragments and silvopastures in the Colombian Andes. Values for adaptable and sensitive avian species represent the percentage of foraging observations that occurred in each tree taxon, and percentage importance values indicate the availability of tree taxa. Sensitive species foraged selectively in forest fragments (P < 0.001) and were not observed in silvopastures, whereas adaptable species were observed in both habitats, but foraged selectively only in forest fragments (P < 0.001). Calculation of Bonferroni confidence intervals resulted in different values for each avian species group, so are not shown here. Instead, significance at α = 0.05 is depicted by asterisks.

African Penguins Get a Little Help from Pretend Friends

https://www.hakaimagazine.com/news/african-penguins-get-a-little-help-from-pretend-friends/?utm_source=Hakai+Magazine+Weekly&utm_campaign=092fa3fc76-EMAIL_CAMPAIGN_2017_09_06_COPY_02&utm_medium=email&utm_term=0_0fc1967411-092fa3fc76-121598265


African penguins are colonial breeders, so they nest where other penguins already live. Researchers from BirdLife South Africa, including Christina Hagen, hope fake penguins made out of cement will fool real penguins into thinking the De Hoop Nature Reserve is a thriving colony.

New bird flu viruses in ducks after vaccines largely prevented H7N9 in chickens

https://www.sciencedaily.com/releases/2018/09/180927145512.htm?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+sciencedaily%2Fplants_animals%2Fbirds+%28Birds+News+--+ScienceDaily%29


The image shows a graphical abstract: H7N9 highly pathogenic avian influenza viruses emerged in China in 2017, prompting vaccination in poultry. Shi et al. examine H7N9 viruses across China before and after vaccination, revealing rapid evolution into subtypes and genotypes. Although vaccination reduced infections, some H7N9 and H7N2 viruses exhibit heightened virulence and expansion to ducks.
