%20(Anas%20platyrhynchos)%2020.jpg)
The Mallard, or wild duck (Anas platyrhynchos), is a familiar and widespread dabbling duck with a presence across temperate and subtropical regions of the Americas, Eurasia, and North Africa. It has also been introduced to parts of the Southern Hemisphere. The male is renowned for its iridescent green head and white collar, while the female sports a brown-speckled plumage. Both sexes boast a speculum—a patch of feathers with iridescent purple or blue hues bordered by white. The Mallard's length ranges from 50 to 65 cm, with a wingspan of 81 to 98 cm, and it typically weighs between 0.7 and 1.6 kg.
Males during the breeding season are unmistakable with their glossy green heads, white collars, and purple-tinged brown breasts. Females are mottled brown with buff cheeks and an eye-stripe. Both sexes have the distinctive speculum on their wings. The male's bill is yellowish-orange tipped with black, while the female's is darker, ranging from black to mottled orange and brown.
Mallards are found in a variety of wetlands, including parks, small ponds, rivers, lakes, and estuaries. They prefer water depths less than 0.9 meters and are drawn to areas with aquatic vegetation.
8-7-2020 L'ESTANY DE CULLERA, VALENCIA - EURASIAN COOT (FEMALE AND JUVENILE) (Fulica atra)
The Eurasian coot is found on freshwater lakes and ponds and has adapted well to urban environments, often seen in city parks and gardens with water bodies.
This bird has a broad range across the Old World, including Europe, Asia, Australia, New Zealand, and parts of North Africa. It is a resident in milder regions but migrates south and west from much of Asia during winter.
The Eurasian coot is less secretive than many rails, often visible on open water or grasslands. It is territorial and aggressive during the breeding season, with both parents defending their territory. In non-breeding seasons, coots may form large flocks. They are reluctant flyers, preferring to run across water surfaces, and are known for bobbing their heads while swimming.
This species is known for its noisy demeanor, producing a variety of crackling, explosive, or trumpeting calls, which are often heard at night.
Coots build bulky, sometimes floating nests, concealed in vegetation or in the open. Both sexes construct the nest, with the male gathering materials. Clutches typically contain 6-10 buff-colored eggs speckled with black or dark brown. Both parents incubate the eggs, which hatch after 21-24 days. Chicks are precocial and nidifugous, with distinctive orange-red tips on their down.
8-7-2020 ULLAL DE BALDOVI, ALBUFERA - LITTLE GREBE (Tachybaptus ruficollis)
%2020.jpg)
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.

2-7-2020 ROSSELL, CASTELLON - ROCK GRAYLING BUTTERFLY (Hipparchia alcyone)
The Rock Grayling (Hipparchia alcyone or H. semele) is a master-camouflage butterfly found in dry, rocky, and woodland habitats across Europe, particularly in the south and Finland. It rarely shows its dark brown and orange-spotted upper wings, preferring to keep them closed to blend into stones or bark.
Key Facts about the Rock Grayling Butterfly
Camouflage Specialist: Their wings have an intricate grey-and-black pattern underneath (cryptic coloring) that mimics bark or stone, making them nearly invisible when resting.
Behavior: They almost never open their wings, preferring to sit in sunny spots to regulate body temperature.Habitat: They favor warm, dry environments, particularly pine woods, oak groves, and rocky areas, often seen in southern Europe and mountainous regions (up to 1900 m).
Diet: Caterpillars feed on grasses such as Festuca and Arrhenatherum.
Life Cycle: They are univoltine, meaning they produce one generation per year, flying from June to August.
Identification: They have a large wingspan (\(4.6 - 6\text{ cm}\)) and feature prominent black "eyespots" with white centers on their forewings, used to startle predators.
Conservation: While not immediately threatened globally, their populations are experiencing declines, particularly in northern Europe.
2-7-2020 ROSSELL, CASTELLON - GREAT BANDED GRAYLING BUTTERFLY (Brintesia circe)
The Great Banded Grayling (Brintesia circe) is a large, distinctive Nymphalidae butterfly found in Central/Southern Europe and Western Asia, recognized by its white-banded, dark wings. Active from June to October in dry, sunny grasslands, it often rests with closed wings, using cryptic coloration for camouflage.
These butterflies fly in one generation from June to September feeding on nectar of flowers. Larvae feed on various herbaceous plants (mainly on Anthoxanthum, Bromus, Festuca and Sesleria species). The young larvae overwinter.
The species can be found in central and southern Europe (Spain, France, Italy, Greece, southern Germany and Poland), in Anatolia and the Caucasus up to Iran.
These butterflies prefer light woodland, grasslands bordering forest edges and generally dry and bushy environments, at an altitude of 0–1,600 metres (0–5,249 ft) above sea level.
Key Facts about the Great Banded Grayling:
Appearance: Large wingspan (\(65–80\text{ mm}\)), with females generally larger. The wings are dark brown/black with a prominent, broad white band across both wings and a black, white-ringed eyespot on the forewing.
Habitat: Prefers sunny, dry, and shrubby areas, including light woodlands, rocky hillsides, and flower-rich grasslands at altitudes from \(0\) to \(1,600\) meters.
Behavior: Known for a strong, rapid flight. They rarely open their wings while resting, camouflaging against rocky or dry ground. Males frequently consume mineralized moisture from damp patches.
Flight Period: Generally flies in one generation from late June to mid-October.
Lifecycle & Diet: The larva feeds on various grasses, including Festuca, Bromus, and Lolium. The species overwinters as a caterpillar.Adaptation: As a response to hot, dry summers, some populations, particularly females, may undergo a period of aestivation, reducing activity during peak heat.
Distribution: Found across Southern and Central Europe (e.g., France, Italy, Spain, Croatia) and Western Asia (Turkey, Caucasus, Iran).
Appearance Note: It is frequently mistaken for other graylings like the Woodland Grayling (Hipparchia fagi) or Rock Grayling (Hipparchia hermione), but the white band is a key identifier.
2-7-2020 ROSSELL, CASTELLON - MEADOW BROWN BUTTERFLY (Maniola jurtina)
%2020-topaz-upscale-1.4x.jpg)
The meadow brown (Maniola jurtina) is a butterfly found in the Palearctic realm. Its range includes Europe south of 62°N, Russia eastwards to the Urals, Asia Minor, Iraq, Iran, North Africa and the Canary Islands. The larvae feed on grasses.
There is marked sexual dimorphism in this species. The upperside of the male is uniformly light brown with a black ocellus centered white at the apex of the forewing, while the female has a tawny patch more or less extended around this ocella. The underside forewing is ochre-colored bordered with dark beige with the same ocelli at the apex in the male, while the hindwing is greyish to brown with a more or less orange band in the female. The males are also much more active and range far about, while females fly less and often may not move away from the area where they grew up.
