The attraction of insectivorous birds to herbivore-damaged trees

Plants damaged by arthropods can call for help from predators by emitting volatile organic compounds (VOCs). Leaves of herbivore-damaged plants also reflect less light than leaves of undamaged plants. Using these olfactorial and visual cues, predators and parasitoids are able to detect damaged plants from a distance, before they see or smell the actual arthropods. The role of arthropod
predators and parasitoids is well studied in this trophic level interaction but recently there has been several studies showing that also birds can use the same olfactorial and visual cues during foraging. And plants benefit of birds removing the herbivorous arthropods.

#ORNITHOLODAY Live from the Kenyan Rift Valley!
0700 – 1800 UTC

We’re launching #ORNITHOLODAY live from the Kenyan Great Rift Valley where Stu Bearhop’s Masters students will be on their annual field course, with a focus on Hell’s Gate National Park and Lake Naivasha.

Hell’s Gate was famed for its vast vulture populations, but as has been seen right across Africa, these populations have suffered severe declines, with poisoning a serious threat to remaining populations. Stu’s team will discuss the issues around vulture declines and the impacts this is having within the wider ecosystem.

Lake Naivasha’s fish community has been massively impacted on by changes in climate, fishing effort and the introduction of invasive species such as the common carp (a freshwater fish). Stu’s team will discuss these issues and the wider impacts they have on the biodiversity of the lake and surrounding area.
