Seabird Entanglement in Monofilament Fishing Line

Environmental Problems, Pelicans

Unfortunately, I have another image of wildlife entanglement to share, this time a California brown pelican (Pelecanus occidentalis) entangled in monofilament fishing line. This seabird appeared to me to have ingested a hook or lure, so that one end of the monofilament fishing line was down its throat while the remainder of the line was wrapped in and around the pelican’s beak and neck. I have other photos of monofilament fishing line injury to marine wildlife. I also had a blog post some time ago about Seabird and Sea Lion Entanglement Photos.

International Conservation Photography Awards 2012

Environmental Problems, Sea Lion, Sea of Cortez, Underwater Life, Underwater Photography

Art Wolfe hosts the biennial International Conservation Photography Awards (“ICP Awards”). One of my images was honored in the 2010 edition of the competition, so I decided to try again this year. My photograph of a young California sea lion entangled in monofilament fishing line, taken in the Espiritu Santo Biosphere Reserve in Baja California, was selected in the “Natural Environment At Risk” category, which seems quite fitting given the competition is meant to highlight conservation and issues relating to the natural world. Thank you Art and ICP Awards! To see all the recognized images — and you should since there are some spectacular photos in this year’s competition — check out: http://icpawards.com/2012winners.php

Photos of Wildlife Entanglement in Plastic

Unfortunately, I have had a number of opportunities to photograph wildlife entangled in plastic debris. Plastic Debris. We make it, we use it and then we leave it behind. This stuff is killing animals and causing problems everywhere. I find it dismaying every time I come across abandoned netting (ghost nets) or monofilament fishing line in the ocean. Often the monofilament is wrapped around a sea lion’s neck as in these photos, or tangled on a reef where it can snag passing fish or invertebrates. I’ve also come across some animals entangled in plastic shopping bags, such as the brown pelican pictured below. At least plastic shopping bags degrade somewhat when exposed to sunlight, so those animals stand a chance of recovery provided they do not eat the bag in an effort to remove it. Alas, in all three cases shown below I considered how to assist the animal pictured but no opportunity presented itself.

Seabird Entanglement in Plastic

Environmental Problems, Pelicans

This week I licensed a photo of this unfortunate brown pelican (Pelecanus occidentalis) entangled in what appears to be a grocery bag to an environmental education initiative, to illustrate the tangible effects of trash and debris on the marine environment. I originally posted about this bird in 2009. I believe the pelican speared a plastic grocery bag floating on the water, mistaking the plastic bag for prey. I would have loved to see the bird captured by wildlife rehab experts so that the bag could be removed, but the pelican was in a position that would have been difficult to approach successfully. Those parts of the bag that the pelican could grasp with its bill appear to have already been pulled away and I believe the remainder would have disintegrated in sunlight, weaked and fallen off soon. Hopefully the bird ingested no pieces of the bag, since plastic is often found clogging the digestive tracts of many species of seabirds.

Sea Lion Entangled in Monofiliment Line

Environmental Problems, Monterey, Sea Lion

This California sea lion (Zalophus californianus) has a severe neck laceration caused by what is likely monofiliment fishing line wrapped around its neck and digging into its skin. Monofiliment fishing line is an exceptionally thin and strong type of synthetic line used for sportfishing. Given that it is designed to be nearly invisible in the water (so the fish do not see it), it is easy to imagine how a passing sea lion, turtle or diving seabird might become tangled in it were the animal unfortunate enough to encounter abandoned monofiliment line in the water. Abandoned fishing line? Absolutely! Fisherman often simply cut their lines if they are unable to clear a snagged line. The abandoned line will last hundreds of years in the water, waiting there to entangle whatever that it comes in contact with. Such line is quite thin and consequently cuts easily into even the tough hides of sea lions. And it is strong, meant to withstand the pull of strong gamefish, so it will not easily give way even if the sea lion were to somehow gain purchase on it and try to break it. Instead, the monofiliment line will slowly, steadily cut into the sea lion’s flesh, eventually causing the animal to suffer from suffocation, starvation or infection.

Appearances nothwithstanding, this sea lion was simply dozing and had been awake and alert minutes before this photo. However, the injury it is experiencing clearly has the potential for infection. I did not see this sea lion again so do not know if it was rescued and rehabilitated or ?

Seabird Entangled in Plastic

Environmental Problems, Pelicans

To add to my description from yesterday about the pelican entangled in a plastic bag, here is another view of the brown pelican (Pelecanus occidentalis californicus) entangled in a plastic grocery bag. I did consider making a grab for the bird (gently of course), hoping I could restrain it long enough to pluck the bag off its neck, but the pelican’s location on the bluffs made it nearly impossible to reach.

Pelican Entangled in Plastic Bag

Environmental Problems, La Jolla, Pelicans

Discarded plastics and styrofoam are destroying our environment. They wreak havoc especially hard on marine wildlife. I recently came across a textbook example of how such trash can injure and kill in the form of this unfortunate brown pelican (Pelecanus occidentalis californicus) which is entangled in what appears to be a plastic bag. I am reasonably certain it is the lightweight sort normally used at grocery stores. I have a good idea of how this predicament came to pass. Plastic bags blow in the wind until they reach the ocean, at which point they float. As these translucent bags drift along on ocean currents, they look like food to many marine animals. Pelicans typically dive from high in the air onto the prey, piercing the water like a spear. I think this pelican saw the plastic bag as it was foraging over the ocean, thought that the bag was some form of food, made a dive into the water and speared the bag with its beak. The pressure of the pelican driving into the water pushed the bag over the head and down the neck of the pelican, were it now sits like a deadly necklace. It appears that the pelican has, during its preening, bitten away quite a bit of the bag, and hopefully will make enough further progress on the bag that it eventually breaks free and the pelican is liberated. (I have a few other photos of marine animal entanglement, including a sea lion with monofiliment fishing line wrapped around its neck.)

Photos of Boat Strikes of Marine Animals

Environmental Problems, Humpback Whale, Marine Life, Ocean Sunfish

Boat strikes of marine animals are increasingly common, for obvious reasons. It is disappointing to observe a marine animal severely or mortally wounded by a collision with a boat. We have encountered several marine animals bearing unmistakable boat propeller scars:
