American Crows are approximately 16-21 inches long, showcasing an iridescent, uniform black color. These daring birds in North America adapt comfortably to open habitats, flourishing in farmlands, forests, and cities.
Their diets are notably diverse, scavenging on grains, fruits, insects, small animals, carrion, and human food waste. Scientists have also observed them modifying wood and using it to probe a small hole where a spider lives.
Regarding parenting, the Corvidae family is practicing cooperative breeding. In the 1980s, Lawrence Kilham first observed adult and yearling American Crows take turns in parenting. Young crows can stay with their parents for five years or longer1.
Moreover, the West Nile Virus has impacted their numbers by 45% since 1999. Fortunately, thanks to their resilience, they are still a species of least concern.

The Slender-billed Crow, native to Indonesia and Papua New Guinea, is identifiable by its long, thin beak and jet-black plumage. Measuring about 16 inches from beak to tail, they are pretty similar in size to other common crows. You’d find them in the subtropical and tropical forests in Southeast Asia.
The Banggai Crow, unique to Indonesia, sports a length of around 15 inches, a mid-size in the crow world. Its glossy plumage is predominantly black, while its dark eyes have pale irises. This species is adapted to dense forest habitats in the Banggai Islands.
Previously thought to be extinct, searches in the early 2000s rediscovered them. Since then, local communities and governments have taken measures like awareness campaigns and promotion of forest protection. Today, they are critically endangered, with less than 250 mature Banggai Crows in the wild3.
The Mariana crow (Corvus kubaryi) (Chamorro name: åga) is a species of the crow family from the tropical Western Pacific. It is a glossy black bird about 15 inches (38 cm) long and known only from the islands of Guam and Rota.
It is a rare bird which has steadily declined in numbers since the 1960s.[2] On Guam there are no remaining native Mariana Crows, the population having been decimated by the introduction of the brown tree snake.[3] On Rota the population has declined to fewer than 200 individuals,[4] the main threats here being the reduction of suitable habitat because of development and predation. Despite translocations from Rota to the Guam National Wildlife Refuge in the late 1990s and early 2000s, by 2011 the Mariana Crow was extirpated from Guam.[5] Current conservation efforts on Rota include habitat protection,[6] and a captive rear-and-release program.[7] The International Union for Conservation of Nature has rated the bird as being "critically endangered".
The Hawaiian Crow, or Alala, is a medium-sized bird at 19–20 inches long. Notably, it flaunts stark black feathers with brown-tinged wings and tail and a thick, strong beak.
Our last type of crow is the rarest of all corvids and became extinct in the wild in 2002, mainly due to habitat destruction and diseases. However, through conservation efforts, captive birds rose from 20 in the 90s to 115 individuals in 2014. They have been reintroduced into native Hawaiian forests since 2016.
The American Kestrel is a small but energetic falcon commonly found in North America4, central Mexico, and the Caribbean. They can live in open grasslands, harsh deserts, and urban areas.
It is the smallest falcon species, weighing around 8 to 12 inches and weighing approximately 2.8 to 5.8 ounces. At first sight, its vibrant plumage featuring warm-toned shades of rust, gray, and white, paired with a distinct black slash near its eyes, is striking. Its slender, sharp beak is a dark yellow, often tipped with black.
The American Kestrel's diverse diet includes insects, mammals, and birds. Its unique hunting technique involves mid-air hovering and a speedy and precise dive.
The American elm, also known as white elm and common elm, is next on our list of common trees in the United States. It is the largest species of all native elms, reaching a height of 80 ft and a diameter between 2 and 5 ft. American elms are native to eastern North America.
American basswood is native to eastern North America. The large tree species is a well-known honeybee tree. This bee species builds beehives in them, producing basswood honey that is pale in color and has a unique taste. It is also a home for butterflies and a food source for small mammals.
The American cockroach stands out as the largest among common cockroach species. With a reddish-brown hue and a yellowish margin, it measures around 1.6 inches in length. This insect undergoes 6-14 molts, often 13, and lives about 700 days - the longest life cycle in its class5.
The Giant water bug comes next on our list of one of the largest insects in the world. Known as toe-biters or alligator ticks, the giant water bug is a formidable predator in ponds and streams.
These water bugs deliver a painful bite using their giant pincers and inject venomous saliva into their prey. They thrive near slow-moving water and feed on tadpoles and small fish.
The largest species of the giant water bug can grow up to 4.5 inches. The biggest water bugs belong to the genus Lethocerus, with species Lethocerus grandis and Lethocerus maximus striving for the title of the biggest bug in the world.
In South and Southeast Asia, people eat these giant bugs and consider them a wonderful delicacy.
Several species of hares—including the Arctic hare (Lepus arcticus), the mountain hare (L. timidus), and the snowshoe hare (L. americanus)—turn from brown or grayish to white in the winter. The color change is thought to be at least partially linked to photoperiod—that is, the amount of light received during the day. As the days shorten, receptors in the retina transmit that information to the hare’s brain, stimulating the replacement of brown hair to white, starting with the extremities. One study has shown that global warming may be a major threat to the survival of these animals. By reducing snow cover, the climatic phenomenon throws a wrench in the timing of the color change, leaving milk-colored animals to conceal themselves against earth-colored surroundings.
The Atacama Desert is one of the driest places on Earth. According to the Encyclopaedia of Earth, there are around 550 species of plants living in the Atacama Desert with over 60% being endemic.
Early in 2015, the Atacama Desert received a significant amount of rain, seven years worth of rain fell in twelve hours. Sadly as a result of the storm, people were killed, and thousands were left homeless.
The unusual amount of rain caused death and destruction, but it also gave life. Spring 2015 saw the usually dry and desolate looking landscape transform into a bright and vibrant landscape of pinks and purples.
The Pink Cistanthe grandiflora and hundreds of other flowering species emerged in a rare display called “Desierto Florido” or ” Flowering Desert”.
By the end of 2015, the desierto florido was over, and the landscape returned to its usual state.
