Stygiomedusa gigantea, commonly known as the giant phantom jelly, is the only species in the monotypic genus of deep sea jellyfish, Stygiomedusa. It is in the Ulmaridae family. With only around 110 sightings in 110 years, it is a jellyfish that is rarely seen, but believed to be widespread throughout the world, with the exception of the Arctic Ocean. The bell of this deep-sea denizen is more than one meter (3.3 feet) across and trails four ribbon-like oral (or mouth) arms that can grow to more than 10 meters (33 feet) in length.

The giant phantom jelly occurs all around the world with the exception of the Arctic Ocean. They are typically found 61°N–75°S and 135°W–153°E. In areas of high latitude in the Southern ocean, the depth at which the species may be found are at the mesopelagic and epipelagic levels.

Known to be one of the largest invertebrate predators in the deep sea, the giant phantom jellyfish's typical prey consists of plankton and small fish. The S. gigantea tends to be more dominant in locations with a low productivity system, which in turn deters other predatory organisms, like fish, to high productivity systems (coastal, upwelling zones). However, the jellyfish remains an important predator for the deep sea, often competing with squids and whales.

Evidence has been collected to support the first-ever documented symbiotic relationship for an ophidiiform fish, Thalassobathia pelagica. Scientists have observed that the large umbrella-shaped bell of S. gigantea provides food and shelter for T. pelagica, while the fish aids the giant phantom jelly by removing parasites. The S. gigantea's jelly providing shelter for T. pelagica is essential for the fish, considering the lack of shelter resources at such extreme ocean depths. Studies to further support this symbiotic relationship have shown that the two species reassociate with one another even if separated. It was inferred that T. pelagica is able to find its way back to the giant phantom jelly due to neuromasts that increase the sensitivity of low-frequency water movements which the bell of the jellyfish emits.

Instead of alternating between their medusa and polyp stages like most jellyfish, the giant phantom jelly covers their young in their huge bell. As a result, they "give birth" to young that are already at their medusa stage. It is inferred that reproduction of S. gigantea is continuous with one parent estimated to produce fifty to one hundred medusa.

The varied thrush (Ixoreus naevius) is a member of the thrush family, Turdidae. It is the only species in the monotypic genus Ixoreus. Varied Thrushes are stocky songbirds with large, rounded heads, straight bills, and long legs. Usually seen standing horizontally on the ground or in a tree, they often look plump-bellied with a relatively short tail.

The Varied Thrush lives in dark, wet, mature forests in the Pacific Northwest. In its breeding range, which covers Alaska and tapers as it extends south to northern California, it inhabits forests dominated by coastal redwood, Sitka spruce, red alder forests, western hemlock, western red cedar, western larch, or Douglas-fir. In winter it may be found in a broader range of habitats, including parks, gardens, lakeshores, and riparian areas where fruit and berries are abundant.

Varied Thrushes forage on the ground, periodically moving to higher perches in the understory to sing or move between foraging sites. Males reach the breeding grounds before females and start singing to establish territories. They have several threat displays, beginning by cocking the tail, turning it toward an intruder, and lowering the wings. If the adversary remains, the displaying bird will face off, lowering its head, raising and fanning the tail, and spreading its wings out to its side. Occasionally, males peck at or lock bills with each other. While squabbling over territory or chasing away nest intruders, they may dive and swoop through dense vegetation, sometimes hitting branches along the way. Females probably choose where to build the nest—usually in the understory of a mature forest, often in a spot surrounded by old nests (or even directly on top of one). They are usually around 10 feet off the ground and poorly concealed, close to the trunk of a small conifer. The female gathers nest material and weaves an outer layer of fir, hemlock, spruce, or alder twigs. She adds a middle layer with rotten wood, moss, mud, or decomposing grass, which hardens into a dense cup about 4 inches across and 2 inches deep. Finally, she lines the cup with fine grasses, soft dead leaves, and fine moss, and drapes pieces of green moss over the rim and outside of the nest. Males may also defend small sites around bird feeders in the winter, though females seem to use alternative feeding sites to avoid competition. Varied Thrushes are thought to establish monogamous breeding pairs, but how long the birds stay together is not known.

During breeding season, Varied Thrushes eat insects and other arthropods from the leaf litter; in winter they eat mostly berries and nuts. They forage by seizing dead leaves in their bill and hopping backward to clear a spot of ground before examining it for prey. In fall and winter, they switch to fruits and acorns, forming loose flocks around their food. Some of their typical fruits are snowberry, apple, honeysuckle, madrone, mistletoe, manzanita, toyon, ash, salal, cascara, dogwood, blueberry, huckleberry, salmonberry, and thimbleberry. Around human habitation, Varied Thrushes have proven very vulnerable to window strikes as well as predation by domestic and feral cats and collisions with cars.

Male Varied Thrushes sing a whistled, flutelike, sometimes burry tone on a single pitch. They sing mainly in the morning and evening, usually from the top of live conifers. Each song lasts about 2 seconds and is followed by a pause of 3–20 seconds. Successive tones may be on different pitches. This cycle is repeated for 10–15 minutes, until the bird flies to a new perch and starts again. Both males and females make a variety of calls, usually in aggression or defense. Those calls include a short trill, a harsh churrr, and a series of low chect notes. Here

Lethocerus americanus, sometimes called the electric light bug, toe biter or fish killer, is a giant water bug in the family Belostomatidae, native to southern Canada and the United States (north of 35°N; other Lethocerus species are found southwards). It typically has a length around 5–6 cm (2.0–2.4 in). It was originally classified as a species in genus Belostoma. This flattened oval-shaped, brownish insect can get up to 6 cm long. Its front legs are well-developed and adapted to grasping prey, while its flattened back legs are used for swimming.

As its name implies, the giant water bug is found in and around aquatic habitats such as ponds, creeks and streams, marshes, and lake edges. It is a strong flier, and is attracted to lights at night. Giant water bugs are common and found throughout most of North America. They are active from spring to fall, and adults overwinter in mud in aquatic habitats.

This insect is a predator, as indicated by its other common common names, 'toe biter' and 'fish killer'. It eats other aquatic invertebrates, small fish, and amphibians — such as this Pacific chorus frog. Like other members of Family Belostomatidae, the giant water bug may bite humans when disturbed. Bites can be very painful and may even cause permanent damage: upon biting prey the insect injects digestive enzymes to liquefy tissue that can then be sucked out. On humans this can produce a painful lesion.

Lethocerus americanus lays their eggs above water on vegetation, where the male guards it from females that would eat the eggs so the male will bear her offspring instead. Some other giant water bug species lay their eggs on the backs of males. The male then carries the eggs around until they hatch. Adults live about one year.

The ring ouzel (Turdus torquatus) is a mainly European member of the thrush family Turdidae. It is a medium-sized thrush, 23–24 centimetres (9.1–9.4 in) in length and weighing 90–138 grams (3.2–4.9 oz). The male is predominantly black with a conspicuous white crescent across its breast. Females are browner and duller than males, and young birds may lack the pale chest markings altogether.

The ring ouzel has an extensive range, estimated at 9.17 million square kilometres (3.54 million sq mi), and a large population, estimated at 600,000–2 million individuals in Europe (which comprises 95% of the breeding range). The Ring Ouzel is mostly an upland bird, where it breeds in steep sided-valleys, crags and gullies, from near sea level in the far north of Scotland up to 1,200m in the Cairngorms.

The ring ouzel is territorial and normally seen alone or in pairs, although loose flocks may form on migration. When not breeding, several birds may be loosely associated in good feeding areas, such as a fruiting tree, often with other thrushes such as song thrushes or redwings. Ring ouzels are solitary nesters with nests being around 200m apart. Breeding begins in mid-April in the UK, the nests are a bulky cup of dried grass, stems, and mosses which are held together with dried mud and built close to the ground in upland areas.

The ring ouzel is omnivorous, eating invertebrates, particularly insects and earthworms, some small vertebrates, and a wide range of fruit. Most animal prey is caught on the ground. During spring migration and the breeding season, invertebrates dominate the adult's diet and are also fed to the chicks. Predators of the ring ouzel include the tawny owl, long-eared owl, common buzzard, common kestrel and Eurasian sparrowhawk, least weasel and stoat. Most deaths are of young juveniles, and birds hatched early in the season are more likely to survive than later broods.

The most common NFC, a raucous chrrk-chik-chik-chik, is a call that Ring Ouzels also use commonly by day on migration and in flight. Every so often they combine this call with another from their repertoire, for example, the series chrrk-chik-chik-chik ends with a deep and knocking tok. Here is a link so you can listen to this bird too.

The western screech owl (Megascops kennicottii) is a small owl native to North and Central America, closely related to the eastern screech owl. The scientific name commemorates the American naturalist Robert Kennicott. Western Screech-Owls are small owls with stocky bodies. They have somewhat square heads, almost no neck, and conspicuous ear tufts. The tail is short. They are superbly camouflaged birds with a base color that can be grayish, brownish, or reddish-brown (rufous). The upperparts are flecked with white; the breast and belly are pale with dark, spidery streaks. The face is pale, outlined with dark arcs. The eyes are yellow.

Western Screech-Owls live mainly in forested habitats, especially in bands of deciduous trees along canyons and other drainages. Common trees include cottonwood, aspen, alder, water birch, oak, and bigleaf maple. But you can also find Western Screech-Owls in suburbs, parks, deserts, coastal areas, and in mountains up to about 6,000 feet elevation.

Western Screech-Owls are nocturnal. They usually leave their roosts around sunset to forage, returning within a half-hour of sunrise. You may glimpse them perching at the entrances of their roost cavities on sunny winter days. They are "socially monogamous," meaning that pairs raise young together, although both sexes may also mate outside the pair. The male and female in a pair often preen each other. During courtship and mating, they sing duets, and the male presents food to the female. Like many small owls, Western Screech-Owls nest in tree cavities excavated by woodpeckers. They may also use naturally occurring cavities, such as those formed where branches have broken off a trunk. Very occasionally, they nest in cavities in cliffs and banks. They sometimes use nest boxes. Wherever the location, the male owl finds a suitable hole, then calls or leads the female to it, sometimes by carrying an enticing prey item. They may use the same cavity for several years in a row. The Western Screech-Owl does not build a nest, but lays its eggs on whatever material happens to be in the cavity. Western Screech-Owl nest cavities are about 1 foot in diameter and 1 to 1.5 feet deep. Entrances are just big enough to admit an owl's body; presumably this helps prevent larger predators from getting in. Western Screech-Owls sometimes take over the nests of other species. In breeding season, the male roosts near the nest cavity. During the last weeks of the nestling period, the female also leaves the nest, often roosting close enough to the male that their bodies touch. Both adults guard the entrance from crows, jays, and other predators. The male provides almost all the food for the female and young during nesting, while the female incubates eggs and broods the baby owls. She stays with her young constantly for the first 3 weeks, then takes increasingly long breaks to help the male hunt. Owlets leave the nest before they can fly well. They remain with their parents for about 5 weeks after leaving the nest site.

Western Screech-Owls are carnivores. They eat mostly small mammals, thought they also eat birds, fish, amphibians, and invertebrates. Their diet can vary tremendously from place to place and from season to season. Mammal prey includes pocket mice, deermice, grasshopper mice, shrews, woodrats, kangaroo rats, as well as bats and occasionally rabbits. Invertebrate prey include insects, crayfish, worms, slugs, snails, and whip scorpions. They are sit-and-wait predators, perching inconspicuously on tree branches and watching the ground for prey. These owls sometimes perch above creeks, watching for crayfish to emerge from the shallows. They also glean invertebrates from foliage and catch flying insects in midair, or bats leaving a roost. Due to their small size, they are also predated by larger animals such as hawks, skunks, snakes, or larger owls.

Heard at dusk and into the night, the Western Screech-Owl's most distinctive vocalization is its "bouncing ball" song: a series of 5–9 short, whistled hoots, speeding up ping-pong-ball fashion toward the end. The male uses this for territorial and courtship advertising, often calling from a nest tree or a prospective nest site. In duets sung by a mating pair, the female's notes are interspersed with the male's—her voice higher than her mate's, despite her larger size. To stay in contact, pairs of screech-owls use a short "double trill" call; when agitated, they make a barking sound. Adult females whinny in response to the male's bouncing ball song, and to solicit feeding and copulation. Western Screech-Owls snap their bills when approached closely by a potential predator such as a crow, squirrel, or human. Nestlings begin doing this when they are about 8 days old.

The chipping sparrow (Spizella passerina) is a species of New World sparrow, a passerine bird in the family Passerellidae. It is widespread, fairly tame, and common across most of its North American range. Chipping sparrow adult upperparts are streaked with dark rusty brown and gray, with a gray rump and head, with bright chestnut crown, white eyebrow, narrow black eyeline, and black bill. Note that the cheeks and nape of neck are clear gray. Underparts are light gray.

You’ll find Chipping Sparrows around trees, even though these birds spend a lot of time foraging on the ground. Look for them in grassy forests, woodlands and edges, parks and shrubby or tree-lined backyards. Chipping Sparrows seem to gravitate toward evergreens in places where these trees are available. They also use aspen, birch, oak, pecan, and eucalyptus trees. In the mountains, you can find these birds all the way up to treeline.

In summer, male Chipping Sparrows defend territories against other Chipping Sparrows, but often tolerate other species as long as they don’t go too near the nest. Females typically build their nests between 3 and 10 feet off the ground, hidden in foliage at the tip of a branch. They gravitate toward evergreen trees, but also nest in crabapples, honeysuckle tangles, maples, ornamental shrubs, and other deciduous species. Females can be finicky about placement, often beginning to build a nest, then leaving to begin in another spot. Males guard females as they build nests, but they don’t help build. It takes the female 3 to 4 days to finish her nest, a loose cup of rootlets and dried grasses so flimsy you can often see through it. She lines the nest with animal hair and fine plant fibers. Finished nests measure about 4.5 inches across and 2.2 inches deep. After the breeding season, Chipping Sparrows form flocks of several dozen, foraging together among grasses and at bird feeders. Their flight pattern is energetic, straight, and only slightly undulating.

Chipping Sparrows mainly eat seeds of a great variety of grasses and herbs. During the breeding season they also hunt for protein-rich insects, and these form a large part of their summer diet. Chipping Sparrows sometimes eat small fruits such as cherries. Its small size makes these birds vulnerable to many threats. Other birds, mammals, and snakes will prey on both the sparrow and its eggs. Raptors, such as Cooper’s hawk and American kestrel will target adults in flight or while on their nest, but even American crows and blue jays are a threat. In addition to these obvious predators, the eggs of the chipping sparrow may be displaced by the brown-headed cowbird. This parasitic bird lays its eggs in other birds’ nests. The other bird tends to the egg and baby as if it were its own. The chipping sparrow is a frequent target of the cowbird.

Male Chipping Sparrows sing a long, dry trill of evenly spaced, almost mechanical-sounding chips. It’s one of the most common sounds of open woods in spring – but be careful, because Dark-eyed Juncos sound very similar (though a bit more musical) and often live in the same habitats. Songs are about 3.6 seconds long on average, consisting of around 55 nearly identical chip notes in a row. Year round, both sexes use a single chip note to stay in contact with others. Upon sighting a hawk, Chipping Sparrows give a long zeeeee call as an alarm. During courtship, females make a soft, rapid see-see-see-see to attract the attention of her mate.

The gray kingbird or grey kingbird (Tyrannus dominicensis), also known as pitirre, petchary or white-breasted kingbird, is a passerine bird in the tyrant flycatchers family Tyrannidae. The species was first described on the island of Hispaniola, then called Santo Domingo, thus the dominicensis name. Large headed and heavy billed like other kingbirds, the Gray Kingbird has ashy gray upperparts that grade into dark gray-brown wings and tail, with the hint of a dark mask through the eyes.

Gray Kingbirds inhabit open and semiopen habitats, often in coastal areas. In Florida, they are relatively common in towns and agricultural areas, as well as edges of mangrove forest. They occasionally nest as far as 15 miles away from the coast. They frequent trees on the edges of native forest, which in southern Florida might include sea grape, gumbo limbo, Jamaican dogwood, West Indian mahogany, green buttonwood, pigeon plum, silver buttonwood, casuarina, and pitch apple. Breeding habitats as far west as Mississippi and occasionally as far north as North Carolina are likewise coastal, with a mixture of pine and oak in residential and resort settings. On Caribbean islands, Gray Kingbirds also frequent savanna and mountain forests with pine and oak, especially where there is partial deforestation. Although they normally occur in habitats below 1,600 feet, there are reports from sites as high as 9,842 feet in the Andes. Wintering birds from Florida use a wide variety of habitats in the Caribbean and northern South America, including not just coastal lowlands but also the llanos (grasslands) of Venezuela, deforested openings in tropical forest, and even large cities in the northern Andes such as Bogotá. At night, Gray Kingbirds sometimes roost with other Tyrannus flycatchers; their roosts in red mangrove forests may include 150 or more birds.

Soon after returning to Florida in spring, male Gray Kingbirds claim territories of about 2–4 acres by calling and flying around the area. Pairs soon form, their bonds obvious in a flight display in which they fly straight up or in a spiral, crossing each other's paths, calling loudly and snapping their bills as they rise. Paired Gray Kingbirds call and flutter their wings when they meet back at the nest site, a greeting that probably also helps maintain their pair bond. Their generally brash behavior notwithstanding, Gray Kingbirds are surprisingly tolerant of others in their species, though males sometimes give chase early in the breeding season or raise their crest in aggressive display, revealing their scarlet central crown feathers. They frequently chase cowbirds away from the nesting area. Nests are set in a tree fork or on a horizontal limb, often over water, typically about 10 feet up in the tree. One nest measured 9.5 inches across and 2.8 inches tall, with an interior cup 3.4 inches across and 1.4 inches deep. The female constructs a rough cup nest of twigs, stems, and grasses, sometimes lining it with moss, hair, and rootlets. Both members of the pair gather nesting material, but the female selects the nest site, builds the bulky twig nest (as the male observes and guards her), and incubates the eggs, though males may help incubate on occasion. Both adults share chick-rearing duties. After the young have fledged, Gray Kingbirds eventually gather in small flocks prior to migration. During winter, they gather into large roosts in the evening, usually in mangroves if they are in a coastal part of the Caribbean or northern South America. Here they often chase each other and call vigorously before settling in for the night.

Gray Kingbirds prey largely on flying insects which they take in swift, direct flights, sometimes of 100 yards or more. Often the pursuit of prey involves steep dives and deft, zigzagging maneuvers that have given them the nickname “spitfire” in some places (after the British fighter plane of World War II). They usually return to their perch to strip prey of wings or stinger, then consume it. Gray Kingbirds also fly out to glean insects from vegetation, the ground, the surface of a pond, vehicles, or buildings. They even eat small lizards, usually striking them against a branch before consuming them, and there are reports of them eating hummingbirds, and minnows. When eating small fruits, they may hover or perch to pluck them. Other prey include beetles, weevils, bees, hornets, wasps, dragonflies, butterflies, moths, flies, and fly larvae taken from beach wrack. They also eat fruits of royal palm, espino, lantana, moral, coco plum, and West Indian birch.

Males sing a “dawn song;” a somewhat harsh, rolling, rhythmic chatter resembling a longer version of the typical call. Both sexes make a loud, rolling pitirre! throughout the year. Here

The gray kingbird or grey kingbird (Tyrannus dominicensis), also known as pitirre, petchary or white-breasted kingbird, is a passerine bird in the tyrant flycatchers family Tyrannidae. The species was first described on the island of Hispaniola, then called Santo Domingo, thus the dominicensis name. Large headed and heavy billed like other kingbirds, the Gray Kingbird has ashy gray upperparts that grade into dark gray-brown wings and tail, with the hint of a dark mask through the eyes.

Gray Kingbirds inhabit open and semiopen habitats, often in coastal areas. In Florida, they are relatively common in towns and agricultural areas, as well as edges of mangrove forest. They occasionally nest as far as 15 miles away from the coast. They frequent trees on the edges of native forest, which in southern Florida might include sea grape, gumbo limbo, Jamaican dogwood, West Indian mahogany, green buttonwood, pigeon plum, silver buttonwood, casuarina, and pitch apple.
