Comparing seabirds, shorebirds, and wading birds

Here is a general overview of 10 characteristics of seabirds (birds that spend most of their life out at sea), shorebirds (migratory birds that scurry along the shore looking for food), and wading birds (taller birds that wade in wetlands for their food).

10 characteristics of seabirds (Examples include albatross, auk, booby, frigatebird, fulmar, gannet, murre, penguin, petrel, puffin, shearwater, and tropicbirds)

1. Seabirds are pelagic, spending most of their lives far out at sea.
2. Seabirds move toward to coastal areas to breed or raise young for a minimal amount of time.
3. Seabirds are light on their undersides and dark on top (an adaptation known as countershading).
4. Seabirds have more feathers than other types of birds for more insulation and waterproofing.
5. Seabirds have flexible webbed feet to help gain traction as they take off for flight from the sea.
6. Some seabirds have unusually sharp claws used to help grasp fish under the water.
7. Some larger seabirds (e.g., albatross) have long, slim wings allowing them to soar for long distances without getting tired.
8. Some smaller seabirds have short wings for maneuvering at the surface of the water.
9. Seabirds have specialized glands to be able to drink the saltwater and excrete salts.
10. Some seabirds (e.g., gannets) have head shape is usually tapered more efficiency in plunge diving.

10 characteristics of shorebirds (Examples include avocets, black skimmer, oystercatchers, plover, sandpiper, and stilt)

1. Shorebirds have long legs, pointed beaks, and long pointed wings.
2. Most shorebirds are migratory (Impressively some shorebirds fly non-stop for 3-4 days, equivalent to a human running continuous 4-minute miles for 60 hours).
3. Shorebirds wade close to the shore and poke their bills into the ground in search of food.
4. Shorebirds are small to medium size wading birds.
5. Shorebirds tend to frequent wetlands and marshes and are biological indicators of these environmentally sensitive lands.
6. Shore birds are of the order Charadriiformes.
7. Shorebirds are very well camouflaged for their environment and their appearance may vary from place to place as plumage (feather colors) are gained or lost during breeding.
8. Shorebirds typically range in size from 0.06 to 4.4 pounds.
9. Oystercatchers have a unique triangular bill that is a cross between a knife and a chisel.
10. The black skimmer is the only native bird in North America with its lower mandible larger than the upper mandible, which helps the bird gather fish as it skims the ocean surface.

10 characteristics of wading birds (Examples include crane, egret, flamingo, herons, ibis, rail, spoonbill, and stork)

1. Wading birds are found in freshwater or saltwater on every continent except Antarctica.
2. Wading birds have long, skinny legs and toes which help them keep their balance in wet areas where water currents may be present or muddy ground is unstable. Also, longer legs make it easier for them to search for food (forage) in deeper waters.
3. Wading birds have long bills with pointed or rounded tips (depending on what is more efficient for the types of food the bird consumes).
4. Wading birds have long, flexible necks that can change shape drastically in seconds, an adaptation for proficient hunting.
5. Herons have sophisticated and beautiful plumes during the breeding season, while smaller waders such as rails are much more camouflaged.
6. Wading birds may stand motionless for long periods of time waiting for prey to come within reach.
7. When moving, their steps may be slow and deliberate to not scare prey, and freeze postures are common when these birds feel threatened.
8. Adult wading birds are quiet as an essential tool for hunting. Wading birds may be vocal while nestling or while in flocks together.
9. Many wading birds form communal roosts and breeding rookeries, even mixing flocks of different species of wading birds or waterfowl.
10. Wading birds fully extend their legs to the rear when flying. The neck may be extended or not while in flight, depending on the species.

How deep is the ocean?

A picture is always worth a thousand words. So, to illustrate this question I’m using a nifty infographic from Our Amazing Planet relating the world’s tallest mountain to the ocean’s deepest trench. This poster will show you where Denver is in to relation to your average plane flying overhead and how deep sperm whales dive in relation to where the Titanic wreck was discovered!

It’s as easy as A, B, Sea: J for JOIDES

JOIDES stands for the Joint Oceanographic Institutions for Deep Sea Sampling. This project began in the 1970’s as a collaboration between many prominent universities and oceanographic institutes (including Woods Hole and Scripps) to take core samples and study the bottom of the ocean. The vessel used for the project was known as the Glomar Challenge. Since the initial project a JOIDES resolution unfolded in 1985 maintaining the mission of the project. Currently, Mission 330 is underway where they are studying the Louisville Seamount Trail. Learn more here. To date the deepest hole drilled into the earth has been approximately 1.3 miles deep.

Irish moss is also known as carageen. Carageen is a deep red alga that grows around rocky substrates along both coasts of of the north Atlantic Ocean. Carrageenan is a gelatinous material extracted from Irish Moss and can be used as a vegetarian alternative to gelatin. It is found in ice cream, soy milk, diet soda and even used in fake saliva for movie effects.

Epipelagic is the area of the water column extending from the surface of the water down to 700 feet. Since is the only zone that the sunlight can penetrate this is the only zone where plants reside. Consequently, this is where 90% of ocean life hangs out.

The epipelagic zone is also known as the sunlight or euphotic zone.

I love the game Scattegories so I am going to be drawn to learning new words that will help me gain more points.

The Baffin Bay separates Greenland from Canada and is connected to the Atlantic Ocean by the Davis Strait. You won’t be finding any vacation homes along the shores of the Baffin Bay as the surrounding islands are cold and mountainous and the Bay is covered in ice for most of the year.

The Baffin Bay is approximately 700 miles long, varies from 70 to 400 miles in width and ranges from 1,200 to 9,000 feet deep.

How long do seastars live?

Seastars can live up to 35 years in the wild! It really depends on the species. Their wild habitat includes coral reefs, rocky coasts, sandy bottom, or even the deep sea of all the world’s oceans. There are approximately 1,800 different types of sea stars.

They have been known to live up to 10 years in aquariums.

10 brief facts on bioluminescence

We all get excited thinking about bioluminescence in nature. Ironically, that excitement is only one of the reasons animals glow like an elf in Middle Earth. Here are some ‘basics on bioluminescence’ you can share with your friends and family the next time you all ogle a firefly and wonder ‘why?’.

What Marine Conservationists Are Into …

This is a series I featured in the summer of 2012 to get a special sneak peek at the many different personalities behind the scientists, activists, and educators (including bloggers) who play an integral role in the marine science conservation field. It’s essentially an extension of the overwhelmingly popular and well done Tumblr blog, This Is What A Scientist Looks Like, (BCS was featured in April of 2012!) which sets out to illustrate that scientists are not just crazy haired nerds in lab coats. I sent a list of 15 random questions and asked that each person share at least their answers to 5 of them.

30 reasons to be grateful for the ocean

It’s the end of another National Oceans Month. And, on this most lovely of lovely days I’d like to Speak Up For Blue and name 30 reasons to be grateful for the ocean! (OK, and it just so happens to be this Beach Chair Scientist’s birthday)

In no particular order, here are some reasons to appreciate the ocean (and all its glorious ecosystems):

Estuaries (Although the course may change sometimes, rivers always reach the sea. – Led Zeppelin)

  • Nursery grounds for many of the commercially important fish that live in the sea.
  • Make up the public infrastructure that are the harbors and ports used for shipping, transportation, and industry.
  • Serve as a filter for sediments, nutrients, and other pollutants that come from upstream.
  • Coastal areas are home to over half the U.S. population.
  • Mangroves and other estuarine ecosystems are amazing playgrounds and feeding grounds for many wading birds.
  • The smell of low tide!

Intertidal Zone (including littoral zone)

  • Home to the tides going in and out. Where else can we appreciate the ebb and flow of life?
  • This is home to many bivalve species that love to burrow under the muck.
  • We can investigate the wrack line and find many treasures that have washed ashore.
  • Place where my favorite animal, the Atlantic horseshoe crab, likes to come to mate during the full and new moons in May and June.
  • A perfect spot to jump waves with little ones!
  • Home to the lovely and rhythmic sound of waves lapping.

Coral Reefs (Pollution, overfishing, and overuse have put many of our unique reefs at risk. Their disappearance would destroy the habitat of countless species. It would unravel the web of marine life that holds the potential for new chemicals, new medicines, unlocking new mysteries. It would have a devastating effect on the coastal communities from Cairns to Key West, Florida — communities whose livelihood depends upon the reefs. – Former President Bill Clinton.)

  • Support a great diversity of species.
  • Yield compounds that are very important in the medical field (have been used in the treatment of cancer, HIV, cardiovascular diseases, ulcers, and other ailments).
  • Protect shorelines erosion.
  • Center of many country’s tourism income.
  • Home to a myriad of colors and patterns!

Pelagic Zone, Euphotic Zone (Open ocean)

  • The only place large enough for the big blue whale to swim and play.
  • The only place large enough for a blue fin tuna to pick up enough speed.
  • Home to a lot of phytoplankton that helps support oxygen production.
  • Home to the Sargasso Sea the only place special enough for the American eel to breed.
  • Home to peace and solitude.
  • A perfect spot to become humble.

Mesopelagic Zone, Twilight Zone (Open ocean bathyal zone)

  • Home to the many creature with the beautiful twinklings of bioluminescence.
  • Only place deep enough for sperm whales to dive down and grab some food.
  • Home to many elusive squid species.

Deep Sea (Abyssal)

Polar Regions

  • Home to the polar bear (did you know their fur isn’t white? It is actually clear but appears white since it is reflected in the sunlight).
  • Important breeding and mating areas for many migratory species (including the red knot).

And, without it we’d be nothing. Oceans cover about 70% of the earth’s surface, and we rely on it economically, environmentally, and scientifically.

Obviously this is a very personal list and it could go on and on forever. I am looking forward to hearing your reasons to be grateful to the ocean and hope we can get to 100 by the end of the year!
