In this post, I am going to continue on global warming. Not only is aquatic animals affected by global warming but also birds.
The climate is changing. The earth is warming up, and there is now overwhelming scientific consensus that it is happening, and human-induced. With global warming on the increase and species and their habitats on the decrease, chances for ecosystems to adapt naturally are diminishing. Many are agreed that climate change may be one of the greatest threats facing the planet. Recent years show increasing temperatures in various regions, and/or increasing extremities in weather patterns and because of this, migratory birds are greatly affected.
The results of several studies investigated show that as the temperatures becomes warmer, migrant species in temperate latitudes, such as the Pied Flycatcher (Ficedula hypoleuca) also arrive on their breeding grounds earlier than expected stated CMS in a release. Scientists have also been studying the dates on which red-winged blackbirds arrive in northern Michigan, found that warming temperatures have dramatically altered the birds' migration as they now arrive 21 days earlier than they did in 1960. The timing of migrations is critical to the survival of numerous bird species. Beginning their journey too early or late may mean that birds miss the food sources they need to survive. As a result of this, migratory birds are travelling thousands of miles only to find the insects they depend on had their breeding cycle a few weeks earlier based on the temperature rise.
Early spring might lead to a shift in the prey (insect hatching) or a shift in vegetation bloom. Unfortunately these shifts are not in line and may occur before the young birds hatch. As a result the birds may not provide enough food for their offspring.
Hence, please do your part to help the earth, these animals and most importantly YOURSELF by helping to slow down the process of global warming and cooling the Earth! =)
