  • Ardea Alba: the white heron

    Ardea Alba: the white heron

    By Sadie Shields When you walk around the Arcata Marsh, you might come across a bird standing ever-so-casually near the water as it spreads its wings, practically begging to have its photo taken. Meet the white heron, commonly known as the great egret (Ardea alba). The white heron’s striking presence in Humboldt’s wetlands makes it instantly recognizable for its elegance and calm demeanor. Its graceful stance and slow, deliberate movements make it a favorite among visitors, photographers and nature enthusiasts exploring the wonders of the marsh. The great egret is one of North America’s most beautiful wading birds. It stands…

  • Branta Canadesis: The Bird that tolerates human presence

    Branta Canadesis: The Bird that tolerates human presence

    By Sadie Shields You have probably heard the honk before you saw them: the unmistakable cry of the Canada goose signaling a seasonal shift across North America. Whether flying overhead in a V formation or grazing in a suburban park, this large bird has become a menace to many lunches and golf putts.  Recognized by its black head and neck, and a bold white patch on its brown body, the Canada goose is a pretty contrast-looking bird. Adults typically measure 30 to 43-inches-long with a wingspan stretching up to six feet. The males and females look alike, though males are…

  • Poecile rufescens: The Small Colorful Songbird

    Poecile rufescens: The Small Colorful Songbird

    By Sadie Shields The chestnut backed chickadee is a small songbird distinguished by its striking coloration and energetic behavior. According to the Audubon field guide, it measures about 12.5 centimeters in length, with a large tail that seems bigger than its body. Unlike other chickadee species, it displays a rich chestnut-brown back and flanks that contrasts with its black head feathers and bib as well as its white feathered cheeks. It is considered one of the most colorful members of the chickadee family and easy to identify. Native to the Pacific Northwest, it can be found in Alaska, British Columbia,…

    Sayornis saya: the bird who likes to speak

    by Sadie Shields The Say’s Phoebe (Sayornis saya) is popular among the North American bird habitats. It belongs to the tyrant flycatcher family, the largest family of birds in the Americas which includes more than 400 species. This bird can be observed at the Arcata marsh, where it favors dry, open and sparsely vegetated habitats.  Despite its preference for desolate landscapes, the Say’s Phoebe is considered one of the more prevalent bird species in the area. It is named in honor of Thomas Say, often recognized as the father of entomology in the United States. Entomology is the scientific study…

  • Fish of the Week: Cow Sharks

    Fish of the Week: Cow Sharks

    Hexanchus Griseus by Ariana Wilson The ‘Cow shark’ consists of two species: the bluntnose sixgill and broadnose sevengill shark. The sixgill shark is a deep-water dweller with the widest distribution of all shark species, ranging from the northern and temperate regions, where water temperatures are about 40-60 degrees Fahrenheit. Adults are found along the continental shelf at depths of at least 8,000 feet, while juveniles have been known to come as far inshore as Humboldt Bay and the San Francisco Bay Area. Male sixgill sharks reach maturity at about 10 feet, while females fully develop at about 14 feet. The…

  • Record breaking king tides at the start of the year

    by Ursula Newman and Barley Lewis-McCabe Low lying communities of Humboldt Bay faced floods as king tides hit record highs on Jan. 2 and 3, which caused significant damages to the King Salmon and Fields Landing areas. The term king tide is used to describe exceptionally large tides that are influenced by the gravitational pull of the moon and sun.  On Saturday, Jan. 3, the National Oceanic and Atmospheric Administration (NOAA) tide gauge, housed in Humboldt Bay at the north spit measured a high of 10.37 feet, the highest ever recorded since its establishment in 1977. In the days following…

  • What are rare earth elements?

    What are rare earth elements?

    by  Ursula Newman Rare earth elements (REEs) are a group of elements, including the 15 elements in the lanthanide series, plus scandium and yttrium. This group of elements is considered critical, and has applications in the medical field, electronic displays, magnets and more. Cal Poly Humboldt Chemistry and Biochemistry Professor Jorge Monteiro’s research focuses on REEs and he explained some of the common applications of these elements.Neodymium, an REE, makes for the strongest magnets on earth. Batteries, wind turbines and hard drives are some of the most critical examples of items that need neodymium to function. Other REEs, such as…

    Politicians and community members protest Humboldt offshore drilling

    by Nick Escalada In view of swaying sailboats moored in the Eureka Harbor, climate activists, tribal members and local fishermen overflowed the seats of a banquet hall on Jan. 18 as U.S. Congressman Jared Huffman discussed the future of their ocean. “Every time there’s some idiot in the White House that thinks, ‘maybe this time they can do it;’ we need to put this to bed once and for all,” Huffman said. “And that means we need to legislate permanent protection for the West Coast.” Humboldt Waterkeeper, EPIC and the Surfrider Foundation held the Offshore Oil Community Forum in the…

  • Campus needs more native plants

    Campus needs more native plants

    by Nick Escalada Following the demolition of the mold-riddled Campus Apartments, Cal Poly Humboldt’s administration has released broad plans for the future of the now vacant slope by the College Creek parking lot. Aside from a new Student Health building planned to start construction in spring 2027, the university intends to introduce a community of hardy native plants to populate the tract of grass, with a large patch of California poppies already creeping in. This development has opened the way for discussion about plant life across the entire campus, with an enduring point of concern being a large presence of…

  • Going once, going twice, rock out!

    by Barley Lewis-McCabe Geologists, rock enthusiasts, big spenders – or a beautiful combination of the three —  saw the 51st annual Cal Poly Humboldt Geology Club Rock Auction on Friday, Dec. 5. Brooke Stafford, senior geology major and geology club president calls it a pretty big deal.  “The Geology Club mainly revolves around the rock auction,” Stafford said. “It’s an annual event that happens every year and many people look forward to it.”  Entering the green and gold room felt like a new world made with every rocker in mind. Every table was lined with a series of flat rocks…

  • Fish of the Week: Heterodontus francisci

    Fish of the Week: Heterodontus francisci

    The Horn Shark, a misunderstood fish by Ariana Wilson Horn Sharks are solitary, slow-moving predators native to the temperate rocky reefs, algal beds and kelp forests of the Pacific Ocean from California all the way down to western Mexico. They are considered one of the smaller shark species and can grow to four feet long. The majority of their diet consists of clams, mollusks, small crustaceans and sea urchins — which are becoming increasingly abundant on California’s coast. Their mouths are on the underside of their body, positioned to sweep the seabed and crush the hard shells of crustaceans that…
