24-11-2019 MONTE CORONA, VALENCIA - BLACK REDSTART (FEMALE) (Phoenicurus ochruros)

24-11-2019 MONTE CORONA, VALENCIA - EURASIAN GREAT CORMORANT (Phalacrocorax carbo)

The great cormorant (Phalacrocorax carbo), a robust seabird, is cloaked in predominantly black plumage. It is a member of the cormorant family, with a widespread distribution. The species exhibits considerable size variation across its range, with males generally larger than females. Notable features include a longish tail and a distinctive yellow throat-patch. During the breeding season, adults boast white patches on their thighs and throat.

To identify the great cormorant, look for its large size, heavy build, and thick bill. It lacks a crest and its plumage does not have a green tinge, distinguishing it from the common shag. In North America, it is bulkier than the double-crested cormorant and has less yellow on the throat and bill. The white thigh patches are a key identifier.

Great cormorants are found in a variety of aquatic environments including seas, estuaries, freshwater lakes, and rivers. They often nest in colonies close to these water bodies.

This species has a broad distribution, breeding across the Old World, Australia, and the Atlantic coast of North America. Northern populations tend to migrate southward in winter, seeking coasts rich in fish.

24-11-2019 MONTE CORONA, VALENCIA - HOUSE SPARROW (MALE) (Passer domesticus)

The house sparrow (Passer domesticus) is a member of the sparrow family Passeridae. This small bird typically measures around 16 cm (6.3 in) in length and weighs between 24–39.5 g (0.85–1.39 oz). The species exhibits sexual dimorphism, with females and young birds displaying pale brown and grey plumage, while males are characterized by more vibrant black, white, and brown markings.

Males can be identified by their bright black, white, and brown markings, with a distinctive black bib, white cheeks, and a grey crown. Females lack the striking head patterns of males and are predominantly buffish with softer coloration. Juveniles resemble adult females but are generally paler with less defined markings.

The house sparrow is highly adaptable and can thrive in both urban and rural environments. It is commonly found in close association with human habitation and avoids dense forests, grasslands, polar regions, and deserts far from human development.

Native to Europe, the Mediterranean Basin, and much of Asia, the house sparrow has been introduced to various regions worldwide, including parts of Australasia, Africa, and the Americas, making it one of the most widely distributed wild birds.

House sparrows are social birds, often seen in flocks. They exhibit a range of behaviors, including dust or water bathing and communal roosting. Males are known to be territorial around their nesting sites.

The house sparrow's vocalizations are predominantly variations of a simple chirping call. Males may sing or give an "ecstatic call" during the breeding season, and the species uses a variety of calls for different social interactions.

House sparrows are generally monogamous and may mate for life. They can breed in the season following their hatching and often produce multiple clutches per year, with each clutch containing up to five eggs. Nest sites are varied, with a preference for cavities.

An opportunistic feeder, the house sparrow's diet consists mainly of seeds from grains and weeds, but it also consumes insects and other invertebrates, especially during the breeding season when feeding young.

21-11-2019 MONTE CORONA, VALENCIA - EUROPEAN PAPER WASP (Polistes dominula)

The European paper wasp (Polistes dominula) is one of the most common and well-known species of social wasps in the genus Polistes. Its diet is more diverse than those of most Polistes species—many genera of insects versus mainly caterpillars in other Polistes—giving it superior survivability compared to other wasp species during a shortage of resources.

The dominant females are the principal egg layers, while the subordinate females ("auxiliaries") or workers primarily forage and do not lay eggs. This hierarchy is not permanent, though; when the queen is removed from the nest, the second-most dominant female takes over the role of the previous queen. Dominance in females is determined by the severity of the scatteredness in the coloration of the clypeus (face), whereas dominance in males is shown by the variation of spots of their abdomens.

P. dominula is common and cosmopolitan due to their exceptional survival features such as productive colony cycle, short development time, and higher ability to endure predator attacks. P. dominula generally lives in temperate, terrestrial habitats such as chaparral, forest, and grassland biomes. They also have the propensity to colonize nearby human civilizations because man-made structures can act as great shelters and also are located close to the resources such as food.

These wasps have a lek-based mating system. Unlike most social insects, 35% of P. dominula wasps in a colony are unrelated. It is considered an invasive species in Canada and the United States.

21-11-2019 MONTE CORONA, VALENCIA - GARDEN ROSE TORTRIX MOTH (Acleris variegana)

25-3-2017 TUIS CARTAGO, COSTA RICA - ROSENBERG'S GLADIATOR FROG (Boana rosenbergi)

Rosenberg's treefrog (Hypsiboas rosenbergi), also known as Rosenberg's gladiator frog or Rosenberg's gladiator treefrog, is a species of frog in the family of tree frogs (Hylidae) and genus of gladiator frogs (Boana) found in Costa Rica, Panama, Colombia, Trinidad and Tobago and north-western Ecuador. Its scientific name is a testimony to Mr. W. F. H. Rosenberg who collected the type series, and its common name refers to the aggressiveness of males of the species.

20-11-2019 ULLAL DE BOLDOVI, VALENCIA - BLACK HEADED GULL (Chroicocephalus ridibundus)

20-11-2019 ALBUFERA, VALENCIA - SPOTLESS STARLING (Sturnus unicolor)

The Spotless Starling, known scientifically as Sturnus unicolor, is a member of the starling family, Sturnidae. It bears a striking resemblance to its cousin, the Common Starling, but is distinguished by its slightly larger size, measuring 21-23 cm in length and weighing between 70-100 grams. Its plumage is a glossy, oily black, which may exhibit purple or green iridescence under bright light. Notably, during the spring and summer, its feathers are completely devoid of spots, while in winter, it sports only minuscule pale spots.

 

To identify the Spotless Starling, look for its longer throat feathers, which are double the length of those on the Common Starling, creating a pronounced "beard" especially visible when the bird vocalizes. Its legs are a vivid pink, and the bill color changes with the seasons: yellow with a bluish or pinkish base in summer, and a duller, often blackish hue in winter. Juveniles present a dull brown plumage, darker than their common counterparts, with a black bill and brown legs.

  

The Spotless Starling is quite adaptable, inhabiting a variety of open environments from farmlands and olive groves to urban areas. It thrives particularly well in open grazed holm oak woods and in cities like Gibraltar, where it is a common sight.

 

This bird has a more restricted range compared to the Common Starling, being native to the Iberian Peninsula, Northwest Africa, southernmost France, and the islands of Sicily, Corsica, and Sardinia. It is largely sedentary, with its population having expanded northward in recent decades.

 

The Spotless Starling is a sociable creature, often seen in sizeable flocks that can number up to 100,000 in the winter months. These flocks may include Common Starlings as well. It exhibits a strong, direct flight and, like its relative, walks rather than hops.

 

A vocal bird, the Spotless Starling is an accomplished mimic. Its calls are reminiscent of the Common Starling but are notably louder.

 

As a cavity-nesting species, the Spotless Starling makes its home in tree holes, buildings, and cliff crevices. It typically lays a clutch of three to five eggs.

 

An omnivorous bird, the Spotless Starling's diet includes a wide array of invertebrates, berries, and human-provided food scraps.

20-11-2019 ULLAL DE BOLDOVI, VALENCIA - LITTLE GREBE (Tachybaptus ruficollis)

The Little Grebe, or Tachybaptus ruficollis, known colloquially as the dabchick, is the smallest European member of the grebe family. This diminutive water bird measures a mere 23 to 29 centimeters in length and is a common sight in open bodies of water across its range.

In the summer, the adult Little Grebe is a sight to behold with its dark upper parts and a striking rufous coloration on the neck, cheeks, and flanks, complemented by a bright yellow gape. Outside of the breeding season, the plumage turns to a more subdued brownish-grey. Juveniles can be identified by their yellow bills tipped with black and streaked cheeks. In winter, the species is recognizable by its buff plumage, darker back and cap, and distinctive rear end.

The Little Grebe favors heavily vegetated areas of freshwater lakes for breeding. It is adept at using this dense vegetation as a cover.

This bird has a broad range, breeding across Europe, much of Asia down to New Guinea, and most of Africa. In winter, many individuals move to open or coastal waters, and it becomes migratory in regions where waters freeze.

Behavior and diet

Diving: It frequently submerges to dive for food and often surfaces some distance away from where it dived.

Diet: It feeds on submerged plants, aquatic insects, larvae, and small fish.

Sound: The bird can be noisy, making a distinctive whinnying trill. 

19-11-2019 OLIVA, VALENCIA - COMMON WAXBILL (Estrilda astrild)

19-11-2019 OLIVA, VALENCIA - COMMON CHIFFCHAFF (Phylloscopus collybita)

The Common Chiffchaff, Phylloscopus collybita, is a diminutive and sprightly leaf warbler known for its distinctive, onomatopoeic song. This small, migratory passerine is characterized by its greenish-brown upperparts and off-white underparts, with a weight ranging from 6 to 8 grams and a length of 10-12 centimeters.

In the field, look for the Common Chiffchaff's short whitish supercilium, fine dark bill, and dark legs. Its primary projection is short, and the plumage may appear duller and browner as it wears. Juveniles are browner above with yellow-white underparts, but they soon acquire brighter plumage after their first moult.

The Common Chiffchaff breeds in open woodlands with a mix of taller trees and ground cover across northern and temperate Europe, Asia, and parts of north Africa. It prefers woodland with trees at least 5 meters high and an undergrowth of grasses and nettles.

This species has a vast breeding range, extending from Europe to eastern Siberia and northward to about 70 N. It winters in southern and western Europe, southern Asia, and north Africa. The Common Chiffchaff is one of the earliest spring migrants to return to its breeding grounds and one of the last to depart in autumn.

The male Common Chiffchaff is fiercely territorial during the breeding season, defending its core territory against rivals. It exhibits a fearless nature, even attacking predators that threaten its nest. Outside the breeding season, these birds may form small flocks with other warblers.

The song is a cheerful "chiff-chaff," which heralds the arrival of spring. Calls include a "hweet" sound, less disyllabic than the calls of closely related warblers. The song is a key distinguishing feature from similar species, such as the Iberian Chiffchaff.

The female constructs a domed nest on or near the ground, lined with feathers. Clutches typically consist of 2-7 cream-colored eggs, which hatch after 13-14 days. The female assumes most of the responsibility for brooding and feeding the chicks, with the male playing a minimal role.

The Willow Warbler and Bonelli's Warbler are similar species but can be differentiated by their longer primary projection, sleeker appearance, and different vocalizations. The Iberian Chiffchaff, once considered a subspecies, is now treated as a separate species due to differences in song, morphology, and genetics.

The Common Chiffchaff is insectivorous, feeding on a variety of insects and other small invertebrates. It is known to be an active forager, often seen flitting through foliage or hovering briefly to snatch prey.

The Common Chiffchaff is classified as "Least Concern" by the IUCN, with an extensive range and large population. While one subspecies is likely extinct, the overall species does not face significant threats at present, and populations in some areas are increasing.

19-11-2019 MARXUQUERA, VALENCIA - EURASIAN WRYNECK (Jynx torquilla)

The Eurasian wryneck, a member of the woodpecker family, is a bird that captivates with its slender, thrush-like form and its ability to twist its neck in a serpentine fashion. This bird, approximately 16.5 cm in length, boasts a plumage mottled with pale brown, rufous, and blackish bars, and streaks across its upperparts, while its underparts are a creamy white speckled with brown.

To identify the Eurasian wryneck, look for its distinctive barred and mottled upperparts, cream underparts with brown speckles, and a shorter, less dagger-like bill compared to other woodpeckers. The juveniles resemble adults but have a softer, less defined coloration.

The Eurasian wryneck is found in open countryside, woodlands, orchards, and sometimes in deciduous or coniferous forests. It has a preference for old trees and areas with abundant ant populations.

This species breeds across temperate Europe and Asia, with migratory populations wintering in tropical Africa and southern Asia. Some populations are resident in northwestern Africa.

The Eurasian wryneck is known for its head-twisting ability, which it uses as a threat display when disturbed. It is often seen in pairs during the summer and may form small groups during migration. The bird exhibits a high-headed posture with a slightly upward-pointing beak and is capable of clinging to vertical surfaces.

The call is a series of harsh, shrill notes, while the alarm call is a staccato "tuck." At the nest, the bird may hiss when disturbed.

Nesting sites vary and may include tree holes, crevices, or even sand martin burrows. The wryneck lays a clutch of seven to ten white eggs, with both parents sharing incubation duties.

The Eurasian wryneck is unique in its family for its neck-twisting behavior and lacks close visual similarities to other species within its range.

Ants are the primary diet, but it also consumes beetles, larvae, moths, spiders, and woodlice. It forages on the ground and in trees, using its extendable tongue to pick up prey.

The Eurasian wryneck is classified as "Least Concern" by the IUCN. Although its population may be decreasing, it is not at a rate that threatens the species' survival. Conservation efforts, such as the provision of nest boxes, have shown positive effects on population stability in some areas.

18-11-2019 MONTE CORONA, VALENCIA - RED SHIELD BUG (Carpocoris mediterraneus)

Carpocoris mediterraneus, the red shield bug, is a species of shield bug in the family Pentatomidae.

This species is widespread throughout the Mediterranean region (Corsica, Greece, Italy, Morocco, Sardinia, Sicily).

Carpocoris mediterraneus can reach a length of 11–13 millimetres (0.43–0.51 in). The body is shield-like in shape and the elytrae are very thick. The body surface is bright yellow or orange, with four short longitudinal black stripes on the pronotum and five dark spots on the scutellum. The antennae have 5 segments. Legs are yellowish or orange.

This species is similar and can be confused with Carpocoris pudicus, Carpocoris purpureipennis or Carpocoris fuscispinus.

In Carpocoris mediterraneus atlanticus the humeral angles of pronotum are sharp and protruding, the base of scutellum and connexivum are frequently with contrasting black spots and the apex of the scutellum is exceptionally truncated.

These bugs are polyphagous vegetarian. Adults can be found on several flowering plants, especially on parsley (Petroselinum crispum).

28-3-2017 CARARA NAT PARK, COSTA RICA - STRAWBERRY POISON DART FROG (Oophaga pumilio)

The strawberry poison frog, strawberry poison-dart frog or blue jeans poison frog (Oophaga pumilio, formerly Dendrobates pumilio) is a species of small poison dart frog found in Central America. It is common throughout its range, which extends from eastern central Nicaragua through Costa Rica and northwestern Panamá. The species is often found in humid lowlands and premontane forest, but large populations are also found in disturbed areas such as plantations. The strawberry poison frog is perhaps most famous for its widespread variation in coloration, comprising approximately 15–30 color morphs, most of which are presumed to be true-breeding. O. pumilio, while not the most poisonous of the dendrobatids, is the most toxic member of its genus.

Oophaga pumilio is diurnal and primarily terrestrial, and can often be found in leaf litter in both forested and disturbed areas. Studies have shown that the optimal habitat is determined by the male, considering the resource benefits and defense costs. Males tend to expend more energy defending smaller but higher quality areas. There has also been evidence that the better competitors and fighters are the males guarding smaller sites with higher female density. In most Anura the louder the vocalization when competing usually means they are larger in size and in better health. However, in the O. pumilio species researchers have determined that these frogs call out at a lower rate to limit their energetic expenditures. Females, on the other hand, simply distribute themselves according to tadpole rearing sites.

Though brightly colored and toxic, these frogs are relatively small, growing to approximately 17.5–22 mm (0.69–0.87 in) in standard length.

28-3-2017 CARARA NAT PARK, COSTA RICA - GIANT CICADA (MALE) (Quesada gigas)

The giant cicada (Quesada gigas), also known as the chichara grande, coyoyo, or coyuyo, is a species of large cicada native to North, Central, and South America. One of two species in the genus Quesada, it is the widest ranging cicada in the Western Hemisphere.

The giant cicada was discovered by Guillaume-Antoine Olivier in 1790. British naturalist Henry Walter Bates described the shrill songs of the cicadas during his exploration in the Amazon in the late 1840s. There are historical records of the cicada in Bexar County, Texas starting in 1934, but this population died out - possibly due to the extended drought of the 1950s. Since 2005, the cicada population has grown and become widespread in central Texas. It currently ranges from central Texas to as far south as Mina Clavero, Argentina.

The giant cicada is the second-largest North American species, after the empress cicada (Megapomponia imperatoria). Like other Texan species, the giant cicada has an appearance that helps it camouflage into the environment. These true bugs are usually a combination of black, green and brown patterns, with brown to olive eyes and a brownish-green pronotal collar color. Texan cicadas distinguish themselves by sound, rather than appearance.

The giant cicada is the only species of the genus Quesada found in North America. The species feeds off of a wide variety of plant families. As an endothermic species, it has the ability to live in a wide range of environments. In the United States, the giant cicada primarily resides in the South Texas brushland, in an area spanning approximately from Laughlin Air Force Base (near Del Rio, Texas) in the west through Uvalde, San Antonio and Austin in the east, ranging nearly to the western limits of Houston. There have been sightings near cities such as Bellville, Brenham, Chappell Hill and Hempstead, Texas. Further south, its range includes most of the southern half of Texas before entering into Mexico, where it is primarily found from Coahuila, along the Mexican Gulf coast states, through to the Yucatán Peninsula. The species' range typically does not extend inland or far to the west until San Luis Potosí. In the west of Mexico, its range begins just north of Mazatlán and continues southward, along the coast, and inland through Guadalajara, Mexico City and all regions further south.

South of Mexico, the giant cicada is found across much of Belize, El Salvador, Guatemala, Honduras, Nicaragua, Costa Rica, Panama, Brazil, Colombia, Ecuador, Venezuela, the Guianas, Trinidad and Tobago, Bolivia, Peru, Paraguay and Uruguay. In Argentina, the species' range stretches as far south as Buenos Aires and Córdoba and as far west as San Juan and San Luis Provinces.

23-3-2017 SAN GERARDO DE DOTA, COSTA RICA - KEEL BILLED TOUCAN (Ramphastos sulfuratus)

The keel-billed toucan (Ramphastos sulfuratus), also known as sulfur-breasted toucan, keel toucan, or rainbow-billed toucan, is a colorful Latin American member of the toucan family. It is the national bird of Belize. The species is found in tropical jungles from southern Mexico to Colombia. It is an omnivorous forest bird that feeds on fruits, seeds, insects, invertebrates, lizards, snakes, and small birds and their eggs.

17-11-2019 VILLALONGA RESERVOIR, VALENCIA - BLACK REDSTART (FEMALE) (Phoenicurus ochruros)

Distinctive orange tail, best seen when flashed open or in flight. Varies considerably within range. Western birds are darker overall; male is slaty blackish, female smoky grayish overall. Eastern males have extensive orange on the underparts, and females are warm brown. 

Song also varies: western birds give a short trill preceded by a few buzzy intro notes, while eastern birds incorporate buzzy and trilled elements. Calls include high-pitched “tseet” and dry clicks. Occupies varied open habitats, often but not always with a rocky component. Feeds mainly on or near the ground, perching rather upright; sings from prominent perches.

17-11-2019 VILLALONGA RESERVOIR, VALENCIA - EURASIAN GREAT CORMORANT (Phalacrocorax carbo)

17-11-2019 FONT EN CARROS, VALENCIA - WHITE WAGTAIL (Motacilla alba)

17-11-2019 FONT EN CARROS, VALENCIA - HOUSE SPARROW (MALE) (Passer domesticus)

The house sparrow (Passer domesticus) is a member of the sparrow family Passeridae. This small bird typically measures around 16 cm (6.3 in) in length and weighs between 24–39.5 g (0.85–1.39 oz). The species exhibits sexual dimorphism, with females and young birds displaying pale brown and grey plumage, while males are characterized by more vibrant black, white, and brown markings.

Males can be identified by their bright black, white, and brown markings, with a distinctive black bib, white cheeks, and a grey crown. Females lack the striking head patterns of males and are predominantly buffish with softer coloration. Juveniles resemble adult females but are generally paler with less defined markings.

The house sparrow is highly adaptable and can thrive in both urban and rural environments. It is commonly found in close association with human habitation and avoids dense forests, grasslands, polar regions, and deserts far from human development.

Native to Europe, the Mediterranean Basin, and much of Asia, the house sparrow has been introduced to various regions worldwide, including parts of Australasia, Africa, and the Americas, making it one of the most widely distributed wild birds.

28-3-2017 CARARA NAT PARK, COSTA RICA - BLUE THROATED TUCANET (Aulacorhynchus prasinus ssp. caeruleogularis

The Blue-throated Toucanet, Aulacorhynchus caeruleogularis, is a member of the toucan family, Ramphastidae. This near-passerine bird boasts a large bill characteristic of toucans. Adults range from 29 to 37 cm in length and weigh between 120 to 185 grams. Both sexes are similar in appearance, though females tend to be slightly smaller with shorter bills.

The Blue-throated Toucanet's bill is a striking feature, black with a prominent yellow stripe along the culmen and a white vertical strip at its base. The nominate subspecies has a rufous patch near the base of the culmen, while A. c. cognatus lacks this. The plumage is predominantly green, lighter below than above, with the nominate's crown having a bronze tinge and its nape and upper back a yellowy bronze tint. The eye is dark brown, encircled by darker bare skin. A deep blue graces their lower face and throat, and their undertail coverts and the underside of the tail are chestnut. The tail is green at the base, turning blue towards the end with chestnut tips. Immature birds are grayer with browner and smaller chestnut tail tips.

The Blue-throated Toucanet inhabits humid montane forests but can also be found in secondary forests, shrublands, pastures, and plantations.

This species is found in Costa Rica, Panama, and far northwestern Colombia, ranging in elevation from 800 to 3,000 meters in Costa Rica and 600 to 2,400 meters in Panama.

The Blue-throated Toucanet is a non-migratory bird known for its gregarious nature, often forming groups of up to about 10 individuals.

28-3-2017 CARARA NAT PARK, COSTA RICA - GREEN AND BLACK POISON DART FROG (Dendrobates auratus)

The green-and-black poison dart frog (Dendrobates auratus), also known as the green-and-black poison arrow frog and green poison frog (among others), is a brightly-colored member of the order Anura native to southern Central America and Colombia. This species has also been introduced to Oahu, Hawaii in an effort to lower mosquito numbers. It is one of the most variably colored species of poison dart frogs, after D. tinctorius, Adelphobates galactonotus and some Oophaga species. From a conservation standpoint, it is considered to be of least concern by the International Union for Conservation of Nature. Within the reptile and amphibian hobby, D. auratus remains one of the most commonly kept, and easiest-to-breed, dart frogs in captivity, as well as in zoos.

The green-and-black poison dart frog is found in humid lowland and submontane forests at altitudes of 0–1,000 m (0–3,280 ft) in southeastern Nicaragua on the Atlantic slope, eastern Costa Rica on the Atlantic slope and in the southwest on the Pacific slope, widely in Panamá, and into far northwestern Colombia in the Chocó Department. An introduced population exists on Oahu, in Hawaii; the species was intentionally introduced there, in 1932, for mosquito control. Later on, it seems to have also become established on Maui.

16-11-2019 MONTE CORONA, VALENCIA - MEDITERRANEAN HOUSE GECKO (Hemidactylus turcicus)

23-3-2017 TROGON LODGE COSTA RICA - RESPLENDENT QUETZAL (Pharomachrus mocinno)

The resplendent quetzal (Pharomachrus mocinno) is a small bird found in southern Mexico and Central America that lives in tropical forests, particularly montane cloud forests. They are part of the family Trogonidae and have two recognized subspecies, P. m. mocinno and P. m. costaricensis. Like other quetzals, the resplendent is mostly omnivorous; its diet mainly consists of fruits of plants in the laurel family, Lauraceae, but it occasionally also preys on insects, lizards, frogs and snails.

The species is well known for its colorful and complex plumage that differs substantially between sexes. Males have iridescent green plumes, a red lower breast and belly, black innerwings and a white undertail, whilst females are duller and have a shorter tail. Grey lower breasts, bellies, and bills, along with bronze-green heads are characteristic of females. These birds hollow holes in decaying trees or use ones already made by woodpeckers as a nest site. They are known to take turns while incubating, males throughout the day and females at night. The female usually lays one to three eggs, which hatch in 17 to 19 days. The quetzal is an altitudinal migrant, migrating from the slopes to the canopy of the forest. This occurs during the breeding season, which varies depending on the location, but usually commences in March and extends as far as August.

The resplendent quetzal is considered near threatened on the IUCN Red List, with habitat destruction being the main threat. It has an important role in Mesoamerican mythology, and is closely associated with Quetzalcoatl, a deity. It is the national animal of Guatemala, being pictured on the flag and coat of arms; it also gives its name to the country's currency, the Guatemalan quetzal.

This species inhabits amidst lush vegetation, in specially moist rainforests at high elevations (900–3,200 m (3,000–10,500 ft). They populate trees that make up the canopy and subcanopy of the rainforest, though they can also be found in ravines and cliffs. It prefers to live in decaying trees, stumps, and abandoned woodpecker hollows. The vivid colors of the quetzal are disguised by the rainforest. The resplendent quetzal can be found from southern Mexico (southernmost Oaxaca and Chiapas) to western Panama (Chiriquí). The ranges of the two subspecies differ: P. m. mocinno is found in southern Mexico, northern El Salvador, and northwestern Nicaragua, Guatemala and Honduras, while P. m. costaricensis is found in Costa Rica and western Panama. The geographical isolation between the two subspecies is caused by the Nicaraguan depression, a 50 km (31 mi) wide, 600 km (370 mi) long bottomland that contains the two largest lakes in Central America, Lake Managua and Lake Nicaragua, and the deficiency of the breeding habitats in regions adjoining to. The quetzal migrates from its breeding areas in the lower montane rainforest to the pre-montane rainforest on the Pacific slopes for three to four months (July–October), after which they move across the continental divide to the Atlantic slopes.

Quetzal's abundance in its mating areas is correlated with the total number of fruiting species, although the correlation between quetzal abundance and the number of fruiting Lauraceae species is only marginal.

23-3-2017 SAN GERARDO DE DOTA COSTA RICA - MENELAUS BLUE MORPHO BUTTERFLY (Morpho menelaus

The Menelaus blue morpho (Morpho menelaus) is one of thirty species of butterfly in the subfamily Morphinae. Its wingspan is approximately 12 cm (4.7"), and its dorsal forewings and hindwings are a bright, iridescent blue edged with black, while the ventral surfaces are brown. Its iridescent wings are an area of interest in research because of their unique microstructure. Due to its characteristic blue color, Morpho menelaus is considered valuable among collectors and was widely hunted in the 20th century.

This neotropical butterfly is found in Central and South America, including the Cerrado which is a vast tropical savanna in Brazil. Other locations include Mexico and Venezuela. Ancestors of the Morpho menelaus butterfly may have been distributed in the Andean regions. Morpho menelaus is one of the six species of Morpho in Costa Rica. The genus of Morpho is present in regions beginning in Mexico and throughout South America, except Chile. Moreover, the Morpho menelaus struggle to survive in the northern Pacific area of Costa Rica since they can’t tolerate such dry conditions. They also need habitats in old growth forests with proper differentiation between the understories and canopies (Murillo-Hiller & Canet, 2018).
