When Birds and Buildings Collide
It is not that birds are unaware of their surroundings; they are simply not primed, via learning or evolution, to detect hazardous man-made structures that extend into their airspace.

Floating plastic debris is ingested either directly, because the birds believe them to be food items, or indirectly by eating prey that has plastic in their stomach. The result of plastic ingestion is entanglement, ulcers, infections and death to many marine animals.
More rodents means more fleas, and genetic screens of these fleas showed that they carry significant numbers of disease-causing bacterial pathogens called Bartonella.
As their calls continue to change, it is vital that the females’ inner ear adapts to the altered chirps of the male – if they do not adjust their hearing, the species could become extinct.
Their presence in such huge numbers has led scientists to try to discover the impact of this invasive species on the natural ecosystem and native species living in the park.
In total six species, including the northern grey-cheeked salamander, had got significantly smaller, while only one species had got fractionally larger.
The one place where this species is found naturally is a freshwater bog where the plants are in standing water, but it was found that the plant actually does better without standing water.
Study recommends that future research should focus on the availability of shade habitat and the energetic consequences of the behavioural changes that climate change may cause in the species.
Large deer populations are forever altering natural forests by disrupting the soil’s seed banks. Deer are not only slowing down forest succession, in some cases they are preventing forests from establishing in the first place.
Michigan State University (MSU) have recently discovered that livestock, horses in particular, are a significant threat to pandas.
