Hepatic Tanager is the most widely distributed Piranga tanager, ranging from the southwest United States south to northern Argentina. Its English name is based on the liver-red color of the adult male from the northern part of the species' range; however, its scientific name, flava, meaning "yellow," derives from the original description, which is based on a female from Paraguay. These names reflect both a characteristic of the genus Piranga, marked sexual dichromatism, and the broad range of coloration, habitat, and behavior encompassed within the Hepatic Tanager as currently recognized.
Even though the Hepatic Tanager is currently considered one species, much evidence, including a recent study of molecular genetics, indicates that up to 3 species could be recognized, corresponding to the 3 groups of subspecies combined long ago. These groups and their respective species names are the Hepatic Tanager (P. hepatica) of montane pine-oak forests from the southwestern United States to Nicaragua, the Tooth-billed Tanager (P. lutea) of forest edges in foothills and mountains from Costa Rica to northern and western South America, and the Red Tanager (P. flava) of open woodlands of eastern and southeastern South America.

fungus (plural: fungi or funguses is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista.
A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the Eumycota (true fungi or Eumycetes), that share a common ancestor (i.e. they form a monophyletic group), an interpretation that is also strongly supported by molecular phylogenetics. This fungal group is distinct from the structurally similar myxomycetes (slime molds) and oomycetes (water molds). The discipline of biology devoted to the study of fungi is known as mycology (from the Greek μύκης mykes, mushroom). In the past, mycology was regarded as a branch of botany, although it is now known fungi are genetically more closely related to animals than to plants.
Abundant worldwide, most fungi are inconspicuous because of the small size of their structures, and their cryptic lifestyles in soil or on dead matter. Fungi include symbionts of plants, animals, or other fungi and also parasites. They may become noticeable when fruiting, either as mushrooms or as molds. Fungi perform an essential role in the decomposition of organic matter and have fundamental roles in nutrient cycling and exchange in the environment. They have long been used as a direct source of human food, in the form of mushrooms and truffles; as a leavening agent for bread; and in the fermentation of various food products, such as wine, beer, and soy sauce. Since the 1940s, fungi have been used for the production of antibiotics, and, more recently, various enzymes produced by fungi are used industrially and in detergents. Fungi are also used as biological pesticides to control weeds, plant diseases and insect pests. Many species produce bioactive compounds called mycotoxins, such as alkaloids and polyketides, that are toxic to animals including humans. The fruiting structures of a few species contain psychotropic compounds and are consumed recreationally or in traditional spiritual ceremonies. Fungi can break down manufactured materials and buildings, and become significant pathogens of humans and other animals. Losses of crops due to fungal diseases (e.g., rice blast disease) or food spoilage can have a large impact on human food supplies and local economies.
The fungus kingdom encompasses an enormous diversity of taxa with varied ecologies, life cycle strategies, and morphologies ranging from unicellular aquatic chytrids to large mushrooms. However, little is known of the true biodiversity of Kingdom Fungi, which has been estimated at 2.2 million to 3.8 million species.[5] Of these, only about 148,000 have been described,[6] with over 8,000 species known to be detrimental to plants and at least 300 that can be pathogenic to humans.[7] Ever since the pioneering 18th and 19th century taxonomical works of Carl Linnaeus, Christiaan Hendrik Persoon, and Elias Magnus Fries, fungi have been classified according to their morphology (e.g., characteristics such as spore color or microscopic features) or physiology. Advances in molecular genetics have opened the way for DNA analysis to be incorporated into taxonomy, which has sometimes challenged the historical groupings based on morphology and other traits. Phylogenetic studies published in the first decade of the 21st century have helped reshape the classification within Kingdom Fungi, which is divided into one subkingdom, seven phyla, and ten subphyla.

Water lilies are a well studied clade of plants because their large flowers with multiple unspecialized parts were initially considered to represent the floral pattern of the earliest flowering plants, and later genetic studies confirmed their evolutionary position as basal angiosperms. Analyses of floral morphology and molecular characteristics and comparisons with a sister taxon, the family Cabombaceae, indicate, however, that the flowers of extant water lilies with the most floral parts are more derived than the genera with fewer floral parts. Genera with more floral parts, Nuphar, Nymphaea, Victoria, have a beetle pollination syndrome, while genera with fewer parts are pollinated by flies or bees, or are self- or wind-pollinated Thus, the large number of relatively unspecialized floral organs in the Nymphaeaceae is not an ancestral condition for the clade.

The berries of the Virginia creeper resemble purple grapes and contain tiny crystals called oxalate crystals. These crystals are also in the leaves of Virginia creeper. If the leaves or berries are chewed they can cause irritation to the lips, mouth, tongue, and throat. (Google)
When you go out into the countryside and are curious by nature, you start looking at flowers, insects, birds, rocks... although there is always something you are more interested in, which does not mean that this will be the case for the rest of your life.
We are in the 21st century but I do as Linnaeus did in the 18th century, I look at the external characters to satisfy my curiosity and determine which species I am photographing, but scientists are working with techniques of this new millennium.
This introduction comes because after batting my eyelashes at lichenids and hesperids, it turns out that until four days ago it was thought that there was only one species of the genus Spialia, S. sertorius, on the peninsula.
But it turns out that no, in 2016 a new species was discovered, Spialia rosae, which is morphologically identical, shares the same genome and only has differences in mitochondrial DNA and cuticular hydrocarbons, and what is this? :), that is, the smell, (they must have some way of recognising each other).
And as my sense of smell is limited and I don't go around smelling butterflies, all the pictures of S. sertorius become S. cf sertorius, (Cf, confer, confrontese), because maybe it is S. sertorius or S. rosae, or else you can also name it as Spialia sp or Spialia Swinhoe.
Anyway, just as Goya recorded in his old age in 1826, "Aún aprendo".

**********************
Cuando uno sale al campo y es de naturaleza curiosa comienza a observar las flores, los insectos, las aves, las rocas... aunque siempre hay algo por lo que te decantas más, lo que no quiere decir que sea así durante toda tu vida.
Estamos en el XXI pero yo hago como Linneo en el XVIII, me voy fijando en los caracteres exteriores para satisfacer la curiosidad y determinar qué especie estoy fotografiando, pero héte aquí que los científicos trabajan con técnicas de este nuevo milenio.
Viene esta introducción porque tras dejarme las pestañas con los licénidos y los hespéridos, resulta que en la península se pensaba hasta hace cuatro días como quien dice, que sólo había una especie del género Spialia, la S. sertorius.
Pero resulta que no, en 2016 se descubre una nueva especie la Spialia rosae, que morfológicamente es idéntica, comparte genoma y sólo presenta diferencias en el ADN mitocondrial y en los hidrocarburos cuticulares, ¿y ésto qué es lo qué es? :), es decir, el olor, (alguna forma tienen que tener ellas de reconocerse).
Y como mi olfato es limitado y además no voy oliendo mariposas por ahí, todas las fotos de S. sertorius pasan a ser S. cf sertorius, (Cf, confer, confróntese), porque quizá sea S. sertorius o S. rosae, o sino también puedes nombrarla como Spialia sp o Spialia Swinhoe.
En fin, igual que grabó Goya en su vejez en 1826, "Aún aprendo".

The nebula Messier 78 (also known as M78 or NGC 2068) is a reflection nebula in the constellation Orion. It was discovered by Pierre Méchain in 1780.
M78 is the brightest diffuse reflection nebula of a group of nebulae that include NGC 2064, NGC 2067 and NGC 2071. This group belongs to the Orion Molecular Cloud Complex and is about 1,600 light years distant from Earth.
Barnard's Loop (Sh2-276) is an emission nebula in the constellation of Orion.The loop takes the form of a large arc centered approximately on the Orion Nebula. The stars within the Orion Nebula are believed to be responsible for ionizing the loop. Recent estimates place it at a distance of between 518 light years and 1434 light years giving it dimensions of either about 100 or 300 light years across respectively. It is thought to have originated in a supernova explosion about 2 million years ago, which may have also created several known runaway stars.

Red hydrogen emission and blue reflection nebulae, dark molecular clouds and a bright star sitting in the middle, flooding the scene its yellow light... Sounds like the Rho Ophichui region?
Sure. There is, however, another smaller, but similarly colorful area in the sky:
Meet the Cave Nebula!
Officially designated Sh2-155, the Cave Nebula in the constellation Cepheus, is a diffuse nebula of ionized hydrogen with ongoing star formation activity, at an estimated distance of 2400 light-years from Earth. It lies within a larger complex containing emission, reflection, and dark nebulosity.
The name "Cave Nebula" for Sh2-155 was coined by Patrick Moore, presumably derived from photographic images showing a curved arc of emission nebulosity corresponding to a cave mouth. Earlier, the name was already used to refer to another brighter but unrelated reflection nebula in Cepheus, known as Ced 201. The name's application to Sh2-155 has come into vogue through the nebula's inclusion in Moore's Caldwell catalogue as object Caldwell 9.

I love dark nebulas: dust lanes and molecular clouds which occlude starlight and create unique whispy and tendril-like shapes in the sky.
In the constellation Cepheus there's a large emission nebula (IC 1396) which includes the famous Elephant Trunk nebula (IC 1396a), along with interesting dark nebulas (example: LDN 1104, 1111, 1121, 1130, etc). Some of these are included in the LDN and Barnard catalogues, however, after watching the latest Astro Imaging Channel episode, I'm not sure if they've been labelled correctly!

The white tern (Gygis alba) is a small seabird found across the tropical oceans of the world. It is sometimes known as the fairy tern although this name is potentially confusing as it is the common name of the fairy tern (Sternula nereis). Other names for the species include angel tern and white noddy.
Taxonomy
The white tern was first formally described by the Swedish naturalist Anders Sparrman in 1786 under the binomial name Sterna alba.[2] The genus Gygis was introduced by the German zoologist Johann Georg Wagler in 1832.[3] The name Gygis is from the Ancient Greek guges for a mythical bird and the specific alba is Latin for "white".[4]
Molecular phylogenetic studies have shown that the white tern is more closely related to the noddies than it is to the other terns.[5] This implies that "white noddy" would be a more appropriate English name.[6]
The white tern has the following subspecies:[6]
G. a. alba, (Sparrman, 1786): tropical islands of the south Atlantic
G. a. candida, (Gmelin, 1789): Seychelles & Mascarene Islands to central Pacific including southern Maldives excluding ranges of next two subspecies
G. a. microrhyncha, Saunders, 1876: Phoenix, Line and Marquesas Islands
G. a. leucopes, Holyoak & Thibault, 1976: Pitcairn Islands
The subspecies G. a. microrhyncha, the little white tern, is sometimes considered as a separate species, Gygis microrhyncha.[7]
Description
Related to the noddies, the white tern is small with a wingspan of 76–87 cm (30–34 in).[8] It has white plumage and a long black bill.[9] Nesting on coral islands, usually on trees with small branches but also on rocky ledges and on man-made structures, the white tern feeds on small fish which it catches by plunge diving.
Distribution and habitat
The white tern ranges widely across the Pacific Ocean from the coasts of Chile and Colombia to New Zealand and along the eastern and southern coasts of Asia from China to India, the islands of the Indian Ocean, and the coast of South Africa.[10] Rarely it is also found in Japan, Madagascar, Mexico, and on some islands in the Atlantic Ocean. It is a pelagic and epipelagic bird, living along the coast and moving into wooded areas during the breeding season.
Behavior
This species is notable for laying its egg on bare thin branches in a small fork or depression without a nest. This behaviour is unusual for terns, which generally nest on the ground, and even the related tree-nesting black noddy constructs a nest. It is thought that the reason for the absence of nests is the reduction in nest parasites, which in some colonial seabirds can cause the abandonment of an entire colony.[11] In spite of these benefits there are costs associated with tree nesting, as the eggs and chicks are vulnerable to becoming dislodged by heavy winds. For this reason the white tern is also quick to relay should it lose the egg. The newly hatched chicks have well developed feet with which to hang on to their precarious nesting site. It is a long-lived bird, having been recorded living for 42[12] years.

The Rosette Nebula (C50) is a beautiful H-alpha nebula, located near the end of a giant molecular cloud in the Monoceros region of the Milky Way.
Due to it's beauty and relatively high apparent brightness, it is a very popular target for deep space imaging. Its photographic attractiveness probably is the reason, why its equally stunning surroundings are often overlooked.
At about 200mm focal length, the Rosette Nebula shares the field of view with the Christmas Tree Cluster (NGC2264) and the Cone Nebula, a cone shaped, cold hydrogen molecular cloud blocking the light of a faint emission nebula behind it. Both the Cone and Rosette Nebula are part of a giant star forming complex.
I captured this "deepscape" of the Rosette and Christmas Tree region of our sky setting behind this landmark peak, during my skiing vacation in Arosa, Switzerland. The foreground lighting comes from snowcats preparing the slopes for another day of perfect skiing.
Capturing such an alignment normally involves quite a bit of cross country hiking with a huge backpack full of equipment.
For this alignment however, I was very lucky. Our appartment was perfectly located for this image and I was able to capture this image from our balcony while sitting in the warm living room.

The Perseus molecular cloud, located at the junction of Taurus, Aries, and Perseus, about 1,000 light-years away from the Earth. It contains over 10,000 solar masses of gas and dust covering an area of 6 by 2 degrees, is the closest giant molecular cloud actively forming large numbers of low to intermediate-mass stars. Unlike the Orion molecular cloud, Perseus molecular cloud is almost invisible apart from two clusters, IC 348 and NGC 1333, where low-mass stars are formed.
By accumulating a very-long-time of exposure, the dust and gas show up, exhibit a complex and chaotic structure consisting of dense cloud cores surrounded by an interconnected network of filaments and sheets. Many voids surrounded by partial arcs or nearly complete rings are also seen. This complicated structure is one possible signature of supersonic turbulence.
The eastern (upper) end of the cloud is associated with IC 348 that contains several hundred young stars. Most of the star formation in IC 348 took place within the last 3 Myr, but some stars in this region formed 10 Myr ago. The apparent age spread in IC 348 may be an indication that two episodes of star formation have occurred. IC 348 appears to be an example of a region that is at or near the end of its star-forming phase.
The western (lower) portion of the Perseus cloud contains the most active region of star formation in the Perseus molecular cloud, including the NGC 1333 cluster. It contains around 150 stars with a median age of a million years, is one of the most active sites of ongoing star formation in the sky within 1500 light-years of the Sun. The molecular ridge extending south (left) from NGC 1333 contains many Herbig–Haro objects, which are bright patches of nebulosity associated with newborn stars.
Between IC 348 and NGC 1333, right in the middle of this photo, there is an area that appears pinky, which is a low-surface brightness HII region surrounded by a dust ring G159.6-18.5, which appears to lie behind the obscuration of the Perseus molecular cloud. The intense ultraviolet light emitted by the central star HD 278942 ionizes the surrounding hydrogen, giving this region its characteristic pink color. The star appears red in this photo and would have been a blue-white star if it were not obscured by dust. The presence of HD 278942 and its HII region suggests that that massive stars may have formed in the recent past within the Perseus molecular cloud.
BTW, the cloud of dust, which obscures the central star and the HII region, is called the“Flying Ghost Nebula” because of its shape.
The area to the west (lower) of the HII region looks relatively empty without too much dense dust, and particularly dark here because the extinction in this region remains high. Perhaps this dead-zone is the youngest portion of the Perseus molecular cloud, formed by the expansion of the dust ring G159.6-18.5.
There are more areas full of dense dust to the south (left) of NGC 1333, see another photo I took if you are interested: www.flickr.com/photos/steedjoy/50855451732/

Corona Australis is a reflection nebula of dust clouds and clusters of bright young stars in the southern sky. It is located between the constellations of Sagittarius and Scorpius. In Latin, the name means the Southern Crown. It is the southern counterpart of Corona Borealis, or the Northern Crown. It is sometimes associated with the myth of Dionysus. In the story, Corona Australis represents the crown the god placed in the sky after freeing his mother Semele from the god of the underworld, Hades. The Ancient Greeks saw Corona Australis as a wreath rather than a crown.
Corona Australis contains one of the closest star-forming regions to our Solar System—a dusty dark nebula known as the Corona Australis Molecular Cloud, lying about 430 light years away.
