20-10-2021 RHODES, GREECE - HOODED CROW (Corvus cornix)


The Hooded Crow, known scientifically as Corvus cornix, is a striking bird found across parts of Europe and the Middle East. It is characterized by its ashy grey body contrasted with a black head, throat, wings, tail, and thigh feathers. The bird's bill, eyes, and feet are also black, creating a distinctive two-tone appearance. Males are generally larger than females, but both share the same coloration.

Adult Hooded Crows are identifiable by their grey and black plumage, with the grey parts appearing streaky due to the dark shafts. The bill and legs are black, and the iris is dark brown. Juveniles can be recognized by their duller plumage and bluish or greyish eyes, with a red mouth that fades as they mature. The wingspan of this bird is approximately 105 cm, and it weighs around 510 grams on average. 


The Hooded Crow is adaptable and can be found in a variety of habitats including farmlands, coastal areas, and urban environments. It is also commonly seen in woodlands and on cliffs where it may forage or nest.

This species has a broad range, inhabiting Northern, Eastern, and Southeastern Europe, as well as parts of the Middle East. In areas where its range overlaps with the Carrion Crow, hybrids can occur, though they are less common due to the Hooded Crow's reclassification as a distinct species.

The Hooded Crow is an omnivorous and opportunistic feeder, known for its intelligence and adaptability. It is a scavenger that will eat a wide variety of foods, and it is also known to hide food for later consumption. The bird's flight is described as slow and heavy, and it often flies straight.

The vocalizations of the Hooded Crow are similar to those of the Carrion Crow, with a distinctive "kraa" call note that is difficult to distinguish between the two species.

Breeding occurs at different times depending on the region, with nests typically found in tall trees, cliffs, or even buildings. The nests are made of sticks and may include seaweed, bones, and wire. The eggs are blue with brown speckles, and the female incubates them alone while being fed by the male. Young fledge after about 32 to 36 days.


The Hooded Crow can be confused with the Carrion Crow and the Rook, but its grey and black plumage makes it visually distinct. The calls of the Hooded and Carrion Crows are nearly identical, adding to potential confusion.

The diet of the Hooded Crow includes molluscs, crabs, eggs of other birds, small mammals, scraps, smaller birds, and carrion. It is known to drop shellfish from heights to break them open and will hide food for later consumption.

The Hooded Crow is not currently considered threatened and is classified as Least Concern by the IUCN. It has a large population and an extensive range, with no significant decline observed in recent years.

20-10-2021 RHODES, ĢREECE - PLAIN TIGER BUTTERFLY (Danaus chrysippus)


Danaus chrysippus, also known as the plain tiger, African queen, or African monarch, is a medium-sized butterfly widespread in Asia, Australia and Africa. It belongs to the Danainae subfamily of the brush-footed butterfly family Nymphalidae. Danainae primarily consume plants in the genus Asclepias, more commonly called milkweed. Milkweed contains toxic compounds, cardenolides, which are often consumed and stored by many butterflies. Because of their emetic properties, the plain tiger is unpalatable to most predators. As a result, its colouration is widely mimicked by other species of butterflies. The plain tiger inhabits a wide variety of habitats, although it is less likely to thrive in jungle-like conditions and is most often found in drier, wide-open areas.

D. chrysippus encompasses three main subspecies: D. c. alcippus, D. c. chrysippus, and D. c. orientis. These subspecies are found concentrated in specific regions within the larger range of the entire species.

The plain tiger is believed to be one of the first butterflies depicted in art. A 3,500-year-old ancient Egyptian fresco in Luxor features the oldest known illustration of this species.


 D. chrysippus is a medium-sized butterfly with a wingspan of about 7–8 cm (2.8–3.1 in). The body is black with white spots. The wings are a brownish orange, the upper side brighter and richer than the underside. The apical half of the forewing is black with a white band. The hindwing has three black spots in the centre. The wings are bordered in black and outlined with semicircular white spots. This species exhibits slight sexual dimorphism, as the male has large scent glands on his hindwings, which the female lacks. They appear as a large black spot with a white centre if viewed from the underside

D. chrysippus is a polymorphic species, so the exact colouring and patterning vary within and between populations.

It is similar in appearance to the Indian fritillary (Argynnis hyperbius), which may coexist with it.

The plain tiger is found across the entirety of Africa, where the predominant subspecies is D. c. alcippus. Its range extends across the majority of Asia throughout Indian subcontinent, as well as many south Pacific islands. The plain tiger is even present in parts of Australia. D. c. chrysippus is most common throughout Asia and in some select regions in Africa, while D. c. orientis is present in more tropical African regions as well as some African islands, including Madagascar and the Seychelles.It is also found in Southern Europe and Kuwait. These insects are considered bioinvaders in North America.

The plain tiger prefers arid, open areas, and is found in a variety of habitats, including deserts, mountains, deciduous forests, and human-tended gardens in cities and parks. It is comfortable at altitudes ranging from sea level to around 1,500 m (4,900 ft).

20-10-2021 RHODES, GREECE - LANG'S SHORT TAILED BLUE BUTTERFLY (Leptotes pirithous)


Leptotes pirithous, commonly known as Lang's short-tailed blue or common zebra blue, is a butterfly of the family Lycaenidae.

Leptotes pirithous is a small butterfly with a wingspan of 21–29 mm (0.83–1.14 in) in males and 24–30 mm (0.94–1.18 in) in females. The uppersides of the wings are purple bluish in males, bluish brown in female. The undersides are dark beige striped with white lines. The hindwings show marginal orange and black spots and two small tails. For the design of the undersides of the wings they can be confused with Lampides boeticus and Cacyreus marshalli.

These butterflies fly from February to November depending on the location. They are regular migrants.

The larvae feed on the flowers and fruits of Fabaceae, Rosaceae and Plumbaginaceae species, including Plumbago capensis, Indigofera, Rynchosia, Vigna, Burkea, Mundulea, Melilotus, Crataegus, Quercus suber, Medicago sativa, Trifolium alexandrinum, Arachis hypogaea, Lythrum, Calluna, Genista, Dorycnium, Lythrum salicaria, Calluna vulgaris, Onobrychis viciifolia, Ulex and Melilotus alba. A life cycle takes about four to eight weeks, depending on the temperature.

20-10-2021 RHODES, GREECE - ORIENTAL HORNET (Vespa orientalis)


The Oriental hornet (Vespa orientalis) is a social insect species of the family Vespidae. It can be found in Southwest Asia, Northeast Africa, the island of Madagascar (but no reports have been made of its presence on the island for many years), the Middle East, Central Asia, and parts of Southern Europe. Oriental hornets have also been found in a few isolated locations such as Mexico and Chile due to human introduction. The Oriental hornet lives in seasonal colonies consisting of caste system dominated by a queen. The hornet builds its nests underground and communicates using sound vibrations. The hornet has a yellow stripe on its cuticle (exoskeleton), which can absorb sunlight to generate a small electrical potential, and this might help supply energy for digging. The adult hornet eats nectar and fruits and scavenges for insects and animal proteins to feed to its young. Because they are scavengers, the hornets may also serve as a transmitter of disease following consumption of infected plants. The hornets are a primary pest to honey bees, attacking bee colonies to obtain honey and animal proteins. The sting of an Oriental hornet can be quite painful to humans and some humans are allergic to stings.


Oriental hornets can be found in Central Asia, southwestern Asia from Armenia and Turkey to India and Nepal, throughout the Middle East, in Northeast Africa, in some Afrotropical countries such as Ethiopia and Somalia, and in parts of Southern Europe: Croatia, Bosnia, Montenegro, North Macedonia, Albania, Greece, Spain, Bulgaria, Cyprus, Malta, Sicily, Sardinia and the southern half of peninsular Italy. Oriental hornets have been introduced by humans into additional locations, including Chile, Madagascar, Mexico, and Xinjiang, China, as well as the occasional introduction via fruit into Belgium and the United Kingdom.The Oriental hornet is the only member of the genus Vespa that can be found in desert climates such as those in North Africa, the Middle East, and parts of southwestern Asia.

17-10-2021 KAVALA, GREECE - YELLOW LEGGED GULL (Larus michahellis)


The Yellow-legged Gull (Larus michahellis) is a large, robust seabird with a commanding presence. Its size can be quite variable, with the smallest females being scarcely larger than a Common Gull, and the largest males approaching the heft of a Great Black-backed Gull. Adults typically exhibit a grey back, a shade lighter than that of the Lesser Black-backed Gull, and their heads are notably whiter in the autumn months. A distinctive feature is their yellow legs, which give this species its common name.


When observing the Yellow-legged Gull, look for the yellow legs that contrast with the grey back and the white head, which becomes even whiter during the autumn. The wing tips are black with limited white spots, and adults have a red spot on the bill. The eye is surrounded by a red ring. Juveniles can be identified by their paler head, rump, and underparts, dark bill and eyes, and a black band on the tail.

This gull favors a variety of coastal environments, often nesting on sea cliffs, islands, and occasionally on buildings within urban settings. It is also known to breed on trees in some regions.


 The Yellow-legged Gull has a breeding range centered around the Mediterranean Sea, extending to the Atlantic islands and coasts as far north as Brittany and west to the Azores. Its presence is also noted on the western side of the Black Sea.

The species is known for its adaptability, with many individuals remaining in the same area year-round, while others migrate to milder regions of western Europe or head south to areas such as Senegal and the Red Sea. Post-breeding dispersal can lead to increased numbers in regions like southern England from July to October.

17-10-2021 KAVALA, GREECE - SPOTTED FLYCATCHER (Muscicapa striata)


Spotted flycatchers are one of our summer migrants that spend the winter in Africa. They are one of the latest migrants to reach us, with a few trickling into the country from late April and most arriving from mid-May.
Despite arriving relatively late, spotted flycatchers manage to rear two broods of young before departing at the end of August. The success of the second clutch is increased by fewer eggs being laid, meaning less mouths to fill. They will nest in gardens but the nest is usually well hidden on ledges or behind climbing plants.


Spotted flycatchers prefer large flying insects, including flies and butterflies. However, if the weather is cool and insects aren’t flying, they will take smaller invertebrates from leaves and branches. If poor weather persists, many nests fail as these smaller invertebrates tend to be eaten by the parents rather than fed to the young.

In order to reduce the chances of their invertebrate prey escaping, spotted flycatchers have a series of modified feathers, like bristles, down the sides of the bill. They have also adapted to catch stinging insects. They rub the sting end on their perch to remove it, making the prey safe to eat.


The spotted flycatcher is red listed due to its rapid and consistent population decline with an 89 per cent decrease between 1967 and 2012. Evidence suggests that this is due to poor annual survival rates of first year birds, but conditions in their wintering grounds in Africa may also have contributed to the decline.

Adult Spotted Flycatchers possess grey-brown upperparts and a somewhat pallid underbelly. Their crown and breast are streaked, which is the origin of their common name. They have short, black legs and a black bill shaped to suit their insectivorous diet. Juveniles can be distinguished by their browner plumage and the presence of spots on their upperparts.

These birds favor deciduous woodlands, parks, and gardens, particularly those with open spaces amidst trees.

17-10-2021 KAVALA, GREECE - EURASIAN BLACKCAP (MALE) (Sylvia atricapilla)


The Eurasian blackcap, Sylvia atricapilla, is a common and widespread typical warbler known for its distinctive cap and melodious song. The species exhibits sexual dimorphism with males sporting a black cap and females a chestnut one. The upperparts are generally olive-grey, while the underparts are pale grey. This bird is small and agile, measuring around 13 cm in length with a wingspan of 7–8 cm.

Males can be identified by their black caps and light grey underparts, while females have a reddish-brown cap and a slightly browner hue to their grey upperparts. Juveniles resemble females but have a rufous tinge to their upperparts and a more olive tone on the breast and flanks. The blackcap's tail is dark grey with an olive edge to each feather, and it has a grey bill and legs with a reddish-brown iris.


The blackcap favors mature deciduous woodlands with a well-developed understory. It also occupies parks, large gardens, and overgrown hedges, provided there are tall trees for songposts and dense shrubs for nesting.

This warbler breeds across much of Europe, western Asia, and northwestern Africa. It is a partial migrant, with northern populations wintering in northwestern Europe, around the Mediterranean, and in tropical Africa. Some have adapted to wintering in British and Irish gardens.

Blackcaps are territorial during the breeding season, with males establishing and defending their territories through song and display. They are mainly monogamous and may raise one to two broods per season. The species is known for its leap-frog migration pattern, where northern populations migrate further south than those from the Mediterranean.

10-10-2021 EL PRAT, BARCELONA - MONK PARAKEET (Myiopsitta monachus)


The monk parakeet (Myiopsitta monachus), also known as the monk parrot or Quaker parrot, is a species of true parrot in the family Psittacidae. It is a small to medium, bright-green parrot with a greyish breast and greenish-yellow abdomen. Its average lifespan is approximately 15 years. It originates from the temperate to subtropical areas of South America. Self-sustaining feral populations occur in many places, mainly in areas of similar climate in North America and Europe.

The nominate subspecies of this parrot is 29 cm (11 in) long on average, with a 48-centimetre (19 in) wingspan, and weighs 100 g (3.5 oz). Females tend to be 10–20% smaller, but can only be reliably sexed by DNA or feather testing. Monk parakeets display very subtle sexual dimorphism in the colouration of their crown and wing coverts, but this is not noticeable to the human eye. It has bright-green upperparts. The forehead and breast are pale grey with darker scalloping and the rest of the underparts are very light-green to yellow. The remiges are dark blue, and the tail is long and tapering. The bill is orange. The call is a loud and throaty chape(-yee) or quak quaki quak-wi quarr, and screeches skveet.

The monk parrot is a gregarious species which often breeds colonially, building a single large nest with separate entrances for each pair. It is not uncommon, however, for pairs or individuals to nest outside of colonies, especially during the breeding season. In the wild, the colonies can become quite large, with pairs occupying separate "apartments" in composite nests that can reach the size of a small automobile.[citation needed] These nests can attract many other tenants, including some which cohabit with the monk parakeets. These tenants include many other birds, such as pigeons, sparrows, American kestrels, and yellow-billed teal, but mammals like red squirrels may also occupy a nest.

Their 1–11 white eggs are incubated continuously by the female, during which time the male will provide her with food. Unusually for a parrot, monk parakeet pairs occasionally have helper individuals, often grown offspring, which assist with feeding the young (see kin selection).[citation needed]

Monk parakeets have an average lifespan in their natural environment of 6 years. However, birds in captivity can reach 10 – 20 years.
