A study which was published in journal Animal Behaviour, conducted by University of Sussex researchers, raised fears that bees and or flying pollinators may struggle in winds caused by global warming. study revealed how high wind speed significantly reduces efficiency of ir foraging. researchers conducted a trial where y me visits to artificial flowers and filmed and timed bees under different fan speeds. It was found that bees on an aver took nectar from 5.45 flowers during a 90-second trial. During increased wind speeds, it fell to an aver of 3.73 flowers. Scientists found that it will hamper bee's capacity to supply food to its colony. researchers also studied indirect impact of higher winds by moving flowers.

study furr revealed that, while flower movement did t appear to have an effect on bees, movement of air from fans me m much more hesitant to take off from a flower. It took m time ranging from an initial 0.05 seconds to 54 seconds. study claims that bees usually feed on wildflowers after leaving ir hives. y were lured into shed with sugar-water feeders and only bee was allowed at a time.

Bumblebees' population declining
A recent study showed that population of bumblebees is sharply decreasing in rth America and Europe due to verse impacts of climate change. Bumblebees play a crucial role as pollinators for flowers and some agricultural crops. This specific kind of bees of genus Bombus are becoming extinct and are longer found in Cana. As per National Geographic reports, se have become endangered in US. Bombus is only extant group in tribe Bombini. study was published in journal, Science which found that bumblebees have become less abundant in areas due to rising temperatures.
