Fact #1: At least 30 species of birds the Audubon Society says are potentially threatened by the BP oil spill. These include marsh birds, ocean-dwelling birds and migratory songbirds. All reside in 'Important Bird Areas,' according to Audubon, designated because of their "essential habitat value." Among the most vulnerable species is the brown pelican -- the state bird of Louisiana -- which was only recently removed from the endangered species list. The spill is especially devastating for bird populations because it coincides with the beginning of breeding season.

After our class discussion on the first day, I decided something that really interested me was the recent BP oil spill. Though I have heard much about this catastrophe on the news, I did not have a full understanding of the impact an oil spill of this magnitude has on the world. On the Australian Maritime Safety Authority website, there is a list of many of the effects of oil on wildlife. I learned that though all oil spills are detrimental to wildlife and our ecosystem, there are many different types of oil spills and many varying factors. These factors include but are not limited to:
- the type of oil spilled,
- the location of the spill,
- the species of wildlife in the area,
- the timing of breeding cycles and seasonal migrations,
- and even the weather at sea during the oil spill.
- marine mammals lose body weight when they can not feed due to contamination of their environment by oil
- birds become dehydrated and can starve as they give up or reduce drinking, diving and swimming to look for food
- inflammation or infection in dugongs and difficulty eating due to oil sticking to the sensory hairs around their mouths
- disguise of scent that seal pups and mothers rely on to identify each other, leading to rejection, abandonment and starvation of seal pups
- damage to the insides of animals and birds bodies, for example by causing ulcers or bleeding in their stomachs if they ingest the oil by accident.
I found two interesting pictures:
