7-9-2018 MONTE CORONA, VALENCIA - CATALONIA WALL LIZARD (Podarcis liolepis)

Podarcis liolepis, the Columbretes wall lizard or Catalan wall lizard, is very similar to the other lizards in the genus Podarcis. This species was formerly described as a subspecies of the Iberian wall lizard, but has now been elevated to species status. These are slender lizards with long tails, narrow tapered heads and long thin toes, and stout legs. Colours are variable, although generally grey-brown. Often very subtle spots and stripes along the back and flanks can be seen and these can be more distinguished in the female. The underside is a much lighter cream or beige with sometimes a reddish tint. Adults grow 15–20 cm in length from the nose to tip of the tail. Body length can be a little as one third of the total body length, the tail making up the other two thirds.

Lifespan around 4–5 years. Sexual maturity is reached in their second year. Breeding takes place in spring after they wake from winter hibernation. 1-5 eggs are laid, each around 5x9mm, in cracks in rocks or under stones. During development the eggs swell and after 8 weeks when ready to hatch they can be 8x15mm in size. They hatch out around early July.

They are found in the north-east of the Iberian peninsula, including southern France in parts of the Pyrenees. They are not found above 3400m elevation.

With a lifespan of about 5 years they are an adaptable wall climbing species which can be found in a large number of habitats and frequently around houses and other buildings. Although being a Mediterranean species, they are able to inhabit mountain habitats with cold winters up to 2000 m altitude (Pyrenees, Sistema Ibérico, Sistema Bético).

The Catalonian Wall Lizard is a quite adaptable, well climbing species which can be found in various habitats and even frequently within human settlements. Although being a (sub-)Mediterranean species, it is able to inhabit mountain habitats with cold winters up to 2000 m altitude (Pyrenees, Sistema Ibérico, Sistema Bético).

Being such a "generalist", its distribution ranges from the French Rhône-Valley in the north to the Spanish Sierra Nevada in the south. It shows a great variability which has led to the description of several subspecies:

Podarcis liolepis cebennensis has been described for southern France. But geographic delimination towards the nominate subspecies is doubtful.

The Spanish Columbretes Archipelago is populated by the dark blotched subspecies atratus. However, this might be just an insular morph of the nominate subspecies.

Subspecies sebastiani has been described for the Basque Country area. Presumably, this may be just an ecotype of the nominate subspecies.

In the south of the range, additional - so far undescribed - colour morphs occur (see below).

With regard to this, some intra-specific taxonomic revision might be required.

Distribution of Podarcis liolepis with its currently recognized subspecies. For an overview of all Iberian Podarcis species see map at Podarcis hispanicus.

In north of the range, Podarcis liolepis has contact zones with Podarcis guadarramae. This species lacks of blue outer ventral scales which frequently occur in males of Podarcis liolepis. Podarcis liolepis may also co-occur with Podarcis muralis (e.g. Penyagolosa, E / Castellón) but it is smaller, more slender und usually shows a lighter colouration than the latter one.

12-4-2018 VICTORIA FALLS, ZIMBABWE - BEARDED WOODPECKER (Dendropicos namaquus)

The bearded woodpecker (Chloropicus namaquus) is a species of bird in the family Picidae. It has a distinctive black and white head and brownish barred body. It is native to tropical central Africa. It has an extremely wide range and is a fairly common species, and the International Union for Conservation of Nature has rated its conservation status as being of "least concern". The bearded woodpecker is one of the largest woodpeckers in Africa growing to a length of about 25 cm (10 in). 

5-9-2018 ULLAL DE BOLDOVI, VALENCIA - BLUE TAILED DAMSELFLY (Ischnura elegans)

5-9-2018 EL PALMAR, VALENCIA - BARN SWALLOW (Hirundo rustica)

The barn swallow (Hirundo rustica) is a migratory passerine bird, recognized as the most widespread species of swallow in the world. It is a distinctive bird with blue upperparts and a long, deeply forked tail, known for its graceful flight and agile maneuvers. The adult male of the nominate subspecies is 17–19 cm in length, including elongated outer tail feathers, and has a wingspan of 32–34.5 cm. It is adorned with a rufous forehead, chin, and throat, which are set apart from the off-white underparts by a broad dark blue breast band. The outer tail feathers are elongated, contributing to the iconic "swallow tail."

The barn swallow can be identified by its steel blue upperparts, a rufous face, and a dark blue breast band that separates the rufous from the off-white underparts. The deeply forked tail is a key characteristic, with a line of white spots across the upper tail's outer end. Females resemble males but have shorter tail streamers and less glossy blue coloring. Juveniles are browner with paler rufous faces and whiter underparts, lacking the adult's long tail streamers.

The barn swallow favors open country with low vegetation, such as pastures, meadows, and farmland, often near water. It avoids heavily wooded or steep areas and densely built-up locations. The species typically nests in man-made structures like barns and stables, or under bridges and wharves.

This bird has a vast global range, breeding across the Northern Hemisphere and wintering in much of the Southern Hemisphere. Its distribution spans Europe, Asia, Africa, and the Americas.

Barn swallows are semi-colonial and may settle in groups. They exhibit site fidelity, often returning to the same location annually for breeding. The species is known for its aerial insectivory, catching insects in flight with remarkable agility.

The barn swallow communicates with a variety of calls, including a "witt or witt-witt" and a loud "splee-plink" when excited or deterring intruders. Alarm calls include a sharp "siflitt" for terrestrial predators and a "flitt-flitt" for avian predators. The male's song, used for territory defense and mate attraction, consists of a twittering warble followed by a series of musical notes.

Barn swallows are monogamous and often mate for life, with the male arriving first at the breeding grounds to select a nest site. They build cup-shaped mud nests lined with soft materials, frequently in colonies where each pair defends a territory. The female typically lays two to seven spotted white eggs, with the clutch size varying by latitude.

The diet consists mainly of flying insects, which the barn swallow captures in open areas or follows animals and humans to catch disturbed prey. It may also pick insects from water surfaces, walls, and plants. The species drinks and bathes by skimming over water bodies.

5-9-2018 ALBUFERA, VALENCIA - LITTLE EGRET (Egretta garzetta)

The little egret is a small, white heron that feeds on small fish and crustaceans. Once a very rare visitor from the Mediterranean, little egrets are now a common sight around the coasts of southern England and Wales as they expand their range, possibly due to increasing temperatures caused by climate change. It first bred in the UK on Brownsea Island, Dorset, in 1996, and has been moving northwards ever since; it was recorded as breeding in Berkshire for the first time in 2007.

The little egret is a white heron with black legs and yellow feet. It has a black bill and long plumes on its head and neck during the breeding season.

Found around the coasts and estuaries of England and Wales, more rarely in Scotland and inland.

The long neck plumes of little egrets were once more valuable than gold and were smuggled into Europe during the 19th century. As a result, little egret populations plummeted until laws were put in place to protect them.

The graceful bird is known as egretta garzetta to scientists, simply "garzetta" to Italians; it's the little egret to the rest of us. Related to the heron, this snowy white migratory bird lives in many parts of Eurasia and Africa, preferring marshes and other wetlands for feeding and breeding. It has a long black bill, black legs and bright yellow feet, and spends only part of its time in southeastern Sicily. There are far more pairs in certain regions of Spain, Portugal and Turkey, but little egrets are found as far north as Scandinavia and England. They feed on insects, frogs, small fish and reptiles.

Its annual Winter passage through Sicily on the way to other southern regions is usually a brief one, but the egret, though a rare sight, is not invisible. It grows to a height of about sixty centimetres. Hardly "little," but true herons are much larger. Egretta thula, the snowy egret, is a New World species closely related, and remarkably similar, to the little egret, making this superspecies one of the world's most widespread birds. There are several subspecies, too.

Then there are those bright yellow feet, certainly an unusual characteristic. The egret has been known to dip a foot in water and shake it about a bit to attract fish which it then catches with its long bill. A very efficient lure.

5-9-2018 ALMUSSAFES, VALENCIA - EURASIAN COLLARED DOVE (Streptopelia decaocto)

5-9-2018 ALBUFERA, VALENCIA - SQUACCO HERON (Ardeola ralloides)

5-9-2018 ALMUSSAFES, VALENCIA - EURASIAN COLLARED DOVE (Streptopelia decaocto)

The Eurasian collared dove, also known as the collared dove or Turkish dove (Streptopelia decaocto), is a bird of modest size, presenting a grey-buff to pinkish-grey plumage that is slightly darker above than below. It is recognized by its distinctive black half-collar edged with white on its nape, from which it derives its name. The species exhibits a blue-grey underwing patch and a tail that is grey-buff above, with dark grey and white-tipped feathers below. The sexes appear similar, with juveniles displaying a less developed collar and a brown iris.

To identify the Eurasian collared dove, look for its medium size, slimmer and longer-tailed body compared to a rock pigeon, and a shorter stature than the wood pigeon. The red legs, black bill, and red iris surrounded by a small area of bare skin, which may appear white or yellow, are key features. The bird's song, a three-part cooing "goo-GOO-goo," and a harsh screeching call are also distinctive identifiers.

This species is often found in proximity to human habitation, particularly where food is plentiful and trees are available for nesting. It is not uncommon to see these doves frequenting bird tables and farms.

Originally from warm temperate and subtropical Asia, the Eurasian collared dove has expanded its range dramatically, colonizing colder countries and becoming a permanent resident in many. Its range now includes Europe, North America, and the Caribbean.

 

The Eurasian collared dove is known for its dispersive nature rather than migratory habits. It is a monogamous bird that shares parental duties and can breed throughout the year when food is abundant. The male performs a ritual flight during courtship, and the species can produce several broods annually.

The Eurasian collared dove's song is a distinctive "goo-GOO-goo," while its call is a harsh screech lasting about two seconds, often heard in flight before landing.

Breeding occurs close to human settlements, with nests typically within 1 km of inhabited buildings. The female lays two white eggs, which are incubated by both parents. Breeding can happen year-round in favorable conditions.

The diet of the Eurasian collared dove consists mainly of grain, seeds, shoots, and insects. They are gregarious and can form sizeable flocks in winter around food sources.

The Eurasian collared dove is currently listed as Least Concern on the IUCN Red List, indicating it is not at immediate risk of population decline. However, its invasive status in North America is a cause for ecological concern, as it may out-compete native species and potentially spread diseases to domestic poultry and other birds.

18-4-2018 CHOBE RIVER, NAMIBIA - PIED CROW (Corvus albus)

The pied crow (Corvus albus) is a widely distributed African bird species in the crow genus of the family Corvidae.

Structurally, the pied crow is better thought of as a small crow-sized raven, especially as it can hybridise with the Somali crow (dwarf raven) where their ranges meet in the Horn of Africa. Its behaviour, though, is more typical of the Eurasian carrion crows, and it may be a modern link (along with the Somali crow) between the Eurasian crows and the common raven.

It is about the size of the European carrion crow or a little larger (46–50 cm in length), but has a proportionately larger bill, slightly longer tail and wings, and longer legs. As its name suggests, its glossy black head and neck are interrupted by a large area of white feathering from the shoulders down to the lower breast. The tail, bill, and wings are black, too. The eyes are dark brown. The white plumage of immature birds is often mixed with black. It resembles the white-necked and thick-billed ravens, but has a much smaller bill.

This species, Africa's most widespread member of the genus Corvus, occurs from sub-Saharan Africa, specifically Nigeria, Ghana, Senegal, Sudan, Somalia, Eritrea, Zambia, Botswana, Mozambique and Zimbabwe, south to the Cape of Good Hope and on the large island of Madagascar, the Comoros Islands, Aldabra, Assumption Island, Cosmoledo, Astove Island, Zanzibar, Pemba, and Fernando Po. It inhabits mainly open country with villages and towns nearby. It does not occur in the equatorial rainforest region. It is rarely seen very far from human habitation, though it is not as tied to the urban way of life as the house crow (Corvus splendens) of Asia, and may be encountered far from human habitation in Eritrea. 

5-9-2018 RACO DE OLLA, VALENCIA - BLACK WINGED STILT (Himantopus himantopus)

Black-winged stilts (Himantopus himantopus) are very long-legged wading birds. They are found in both warm and hot climates, feed on small aquatic creatures, and nest on the ground surface in small colonies.

Adult Black-winged stilts have long, pink legs, and a long, rather thin black bill. They are generally black above and white below, with a white head and neck. Males have a black back, often with a greenish gloss or sheen. Females' backs have a brownish hue, contrasting with the black remiges. In populations where the top of the head is normally white (at least in winter), females tend to have less black on the head and neck the entire year round, while males often have much more black, particularly in summer. This difference is not clear-cut, however, and males usually grow all-white head feathers in winter. Immature birds are grey, instead of black, and have a markedly sandy hue on their wings, with light feather fringes appearing as a whitish line in flight.

Striking large black-and-white wader with a thin, straight bill and bright pink legs, found in wetlands with open shallow water throughout much of Africa and Eurasia, often in brackish habitats. Some populations are migratory, departing northerly breeding grounds for warmer southern regions. Often forms noisy colonies on bare ground near water. Essentially unmistakable throughout much of its range, but compare with Pied Stilt in parts of Southeast Asia. Feeds by wading in water, picking from the water surface with its needle-like bill. In flight, long pink legs stick out far beyond the tail. Calls loudly and stridently, especially when alarmed during the breeding season.

The black-winged stilt (Himantopus himantopus) is a widely distributed, very long-legged wader in the avocet and stilt family Recurvirostridae. Its scientific name, Himantopus himantopus, is sometimes used to generalize a single, almost cosmopolitan species. Alternatively, it is restricted to the form that is widespread in Europe, Asia and Africa, which equals the nominate group of H. himantopus sensu lato. Meanwhile, the black-necked (H. mexicanus) and white-backed stilts (H. melanurus) both inhabit the Americas; the pied stilt (H. leucocephalus) ranges from Australasia and New Zealand. Today, most sources accept between one and four actual species. The taxonomic name Himantopus comes from Greek, meaning "strap-foot" or "thong-foot".

5-9-2018 MONTE CORONA, VALENCIA - CATALONIA WALL LIZARD (Podarcis liolepis)

Podarcis liolepis, the Columbretes wall lizard or Catalan wall lizard, is very similar to the other lizards in the genus Podarcis. This species was formerly described as a subspecies of the Iberian wall lizard, but has now been elevated to species status. These are slender lizards with long tails, narrow tapered heads and long thin toes, and stout legs. Colours are variable, although generally grey-brown. Often very subtle spots and stripes along the back and flanks can be seen and these can be more distinguished in the female. The underside is a much lighter cream or beige with sometimes a reddish tint. Adults grow 15–20 cm in length from the nose to tip of the tail. Body length can be a little as one third of the total body length, the tail making up the other two thirds.

Lifespan around 4–5 years. Sexual maturity is reached in their second year. Breeding takes place in spring after they wake from winter hibernation. 1-5 eggs are laid, each around 5x9mm, in cracks in rocks or under stones. During development the eggs swell and after 8 weeks when ready to hatch they can be 8x15mm in size. They hatch out around early July. 

They are found in the north-east of the Iberian peninsula, including southern France in parts of the Pyrenees. They are not found above 3400m elevation.

With a lifespan of about 5 years they are an adaptable wall climbing species which can be found in a large number of habitats and frequently around houses and other buildings. Although being a Mediterranean species, they are able to inhabit mountain habitats with cold winters up to 2000 m altitude (Pyrenees, Sistema Ibérico, Sistema Bético).

The Catalonian Wall Lizard is a quite adaptable, well climbing species which can be found in various habitats and even frequently within human settlements. Although being a (sub-)Mediterranean species, it is able to inhabit mountain habitats with cold winters up to 2000 m altitude (Pyrenees, Sistema Ibérico, Sistema Bético).

18-4-2018 CHOBE RIVER, NAMIBIA - SOUTHERN PALE CHANTING GOSHAWK (Melierax canorus ssp. canorus)

The pale chanting goshawk (Melierax canorus) is a bird of prey in the family Accipitridae. This hawk breeds in southern Africa and is a resident species of dry, open semi-desert with 75 cm or less annual rainfall. It is commonly seen perched on roadside telephone poles.

This species is approximately 55 cm in length with a wingspan of 110 cm. The adult has grey upperparts with a white rump. The central tail feathers are black tipped with white and the outer tail feathers are barred grey and white. The head and upper breast are pale grey while the rest of the underparts are finely barred in dark grey and white. The eyes are dark brown in the adult and pale yellow in the immature. The bill is red at the base and dark grey at the tip. The cere, facial skin and long legs are also red. In flight, the adult has black primary flight feathers, very pale grey (white from a distance) secondaries, and grey forewings. Immatures have brown upperparts, with a white rump and black bars on the tail. From below, the flight feathers and tail are white with black barring, the throat is dark-streaked white, and the rest of the underparts are rufous. It is larger and paler than the barred-rumped dark chanting goshawk, Melierax metabates.

Both sexes are vocal during the breeding season. The call is a tuneful whistling kleeu-kleeu-kleeu-ku-ku-ku usually given from a tree-top perch.

4-9-2018 MONTE CORONA, VALENCIA - MOORISH GECKO (Tarentola mauritanica)

Tarentola mauritanica, known as the common wall gecko, is a species of gecko (Gekkota) native to the western Mediterranean area of North Africa and Europe. It has been introduced to Madeira and Balearic Islands, and the Americas (in Montevideo, Buenos Aires and California). A nocturnal animal with a predominantly insectivorous diet, it is commonly observed on walls in urban environments in warm coastal areas; it can be found further inland, especially in Spain where it has a tradition of cohabitation with humans as an insect hunter. A robust species, up to 15 centimetres (5.9 in) long, its tubercules are enlarged and give the species a spiny armoured appearance.

The species was first described by Carl Linnaeus in 1758. It is also known as moorish gecko, crocodile gecko, European common gecko, and, regionally, as osga (in Portuguese), salamanquesa (in Spanish) and dragó (in Catalan).

The Common wall gecko is a small lizard native to the western Mediterranean area of North Africa and Europe. It is commonly observed on walls in urban environments, mainly in warm coastal areas. However, the Common wall gecko can be found further inland, especially in Spain where it has a tradition of cohabitation with humans as insect hunter. This little creature is brownish-grey or brown in color with darker or lighter spots. These colors change in intensity according to the light. When geckos are active by day their color is darker than during the night.

Common wall geckos are mainly nocturnal or crepuscular. They may also be active during the day, on sunny days especially at the end of the winter. They like to receive sunlight near their refuge. They prefer to forage and spend their time singly; in the warmer months of the year, geckos can often be seen hunting nocturnal insects near light sources and street lamps.

15-4-2018 CHOBE RIVER, NAMIBIA - GREAT WHITE PELICAN (Pelecanus onocrotalus)

3-9-2018 VILLALONGA RESERVOIR, VALENCIA - LITTLE EGRET (Egretta garzetta)

3-9-2018 VILLALONGA RESERVOIR, VALENCIA - GREEN SANDPIPER (Tringa ochropus)

The Green Sandpiper, Tringa ochropus, is a small wader, or shorebird, with a somewhat plump appearance. It boasts a dark greenish-brown back and wings, complemented by a greyish head and breast. The underparts are predominantly white, with the back featuring white spots that vary in extent depending on the season and age of the bird. The legs and short bill are a matching dark green, creating a harmonious color palette for this avian species.

When observing the Green Sandpiper, look for its distinctive flight pattern, which reveals dark wings above and below, punctuated by a striking white rump. This feature is a reliable identifier, setting it apart from its close relative, the slightly smaller Solitary Sandpiper of North America. Additionally, the Green Sandpiper's white-spotted back is most pronounced in breeding adults and less so in winter and juvenile plumage.

The Green Sandpiper is a freshwater aficionado, often found in more confined spaces than other waders, which typically prefer open vistas. It thrives in a variety of freshwater habitats, avoiding the more gregarious nature of some wader congregations.

This bird breeds across subarctic Europe and extends its range east across the Palearctic. It is migratory, seeking winter respite in southern Europe, the Indian Subcontinent, Southeast Asia, and tropical Africa.

The Green Sandpiper is not known for its sociability, as it is rarely seen in large groups. It prefers to forage alone, methodically picking small invertebrate prey from the mud along the edges of ponds and streams.

In flight, the Green Sandpiper emits a characteristic three-note whistle, which can be heard over the quiet waters it frequents.

A unique nester among waders, the Green Sandpiper lays 2 to 4 eggs in the abandoned arboreal nests of other bird species, such as the Fieldfare. The eggs incubate for approximately three weeks before hatching.

The Solitary Sandpiper (T. solitaria) is the Green Sandpiper's closest living relative and the most similar in appearance. However, the Solitary Sandpiper can be distinguished by its smaller size and different geographical range, being native to North America.

The diet of the Green Sandpiper consists of small invertebrates, which it diligently collects from the muddy edges of its freshwater habitat.

The IUCN classifies the Green Sandpiper as Least Concern, indicating a stable global population. It is protected under the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA), ensuring concerted efforts for its conservation.

3-9-2018 VILLALONGA RESERVOIR, VALENCIA - COPPER DEMOISELLE DAMSELFLY (MALE) (Calopteryx haemorrhoidalis)

3-9-2018 VILLALONGA RESERVOIR, VALENCIA - BLACK HEADED GULL (Chroicocephalus ridibundus)

31-8-2018 MONTE CORONA, VALENCIA - EUROPEAN MANTIS (FEMALE) (Mantis religiosa)

The European mantis (Mantis religiosa) is a large hemimetabolic insect in the family of the Mantidae ('mantids'), which is the largest family of the order Mantodea (mantises). Their common name praying mantis is derived from the distinctive posture of the first pair of legs that can be observed in animals in repose. It resembles a praying attitude. Both males and females have elongated bodies with two pairs of wings. The most striking features that all Mantodea share are a very mobile, triangular head with large compound eyes and their first pair of legs (the 'raptorial legs'), which is highly modified for the efficient capture and restraint of fast-moving or flying prey.

In Germany, M. religiosa is listed as Gefährdet [endangered] on the German Red List on the basis of an assessment from 1998. It is not supposed to be caught or held as a pet. At a global level, it is assessed by the IUCN as least concern.

The phenomenon that conspecifics are attacked and eaten after, during, and even before copulation is called sexual cannibalism. Many examples are known in various groups of invertebrates, including the mantids. Some speculations exist about the benefits of this behaviour, but its causes are not fully understood yet. For quite some time, the belief that sexual cannibalism in M. religiosa only occurred in captivity was widespread. It was believed to be an artefact of improper animal keeping (too little food or space). In 1992, however, the cannibalising behaviour of female M. religiosa was observed in a field study. Lawrence compared the percentage of cannibalism in natural and manipulated (males and females were put close together in the field) pairings and found rates of 31% and 24%. This proves that sexual cannibalism in this praying mantid is not caused by laboratory conditions. They can, however, intensify the phenomenon; females that were starved for more than three days were more likely to attack males, even before copulation. While the cannibalisation before the copulation is still puzzling to scientists, some theories about the benefits of sexual cannibalism in general include:

Eating her mate provides the female with nutrients so she does not have to hunt. She has a prey item available that is bigger than the prey she would be able to catch in the manner she usually hunts.

The meal also usually takes place during or shortly after she was fertilised, giving her more resources for the faster production of a large ootheca with large eggs, thus increasing the chance of her offspring to survive. Males have also been known to be more attracted to heavier, well-nourished females for this reason.

At first glance, however, this behaviour does not seem to be very beneficial for the male, since he dies and cannot create more offspring with his genetic material, yet males usually do not mate more than once, anyway. They have a shorter life expectancy than females (7–8 months versus 11–12 months) and since food can begin to become scarce in September and October, the male might starve before he has the chance to mate again. Copulation is also known to take longer when cannibalisation occurs. It seems advantageous to transfer more sperm in this elongated time and additionally provide the female with nutrients. Doing this, the male might just pass on his genes once, but he can ‘make sure’ that his offspring are successful, since they come from a well-nourished female.

Some controversy exists, though, concerning this theory. The absence of elaborate display behaviour does not support this ‘selfless’ behaviour of the males. It could have also been observed that males are more likely to approach a female that is distracted by feeding or cleaning herself. The approach is also happening faster in these cases. The male seems to try to avoid his cannibalisation very actively.

The fact that sexual cannibalisation happens so often is surely also supported because a male without a head can continue and even initiate copulation. The cerebral ganglion might have an inhibitory effect on copulatory reflexes. Once it is removed by removing the head, copulation might even be longer, since the male can never ‘decide’ to let go. A few mantids can also start copulating when the heads of both animals get removed artificially beforehand. The beheaded animals can live up to five hours and usually just die when they bleed out or starve to death.

2-9-2018 GANDIA GRAU, VALENCIA - BARN SWALLOW (Hirundo rustica)

2-9-2018 ADOR CAMPO, VALENCIA - COMMON SANDPIPER (Actitis hypoleucos)

The Common Sandpiper, Actitis hypoleucos, is a small wader of the Palearctic region, easily recognized by its greyish-brown upperparts and pristine white underparts. Adults typically measure between 18-20 cm in length, with a wingspan of 32-35 cm. They possess short, dark-yellowish legs and feet, and a bill that is pale at the base with a dark tip.

In the field, look for the Common Sandpiper's distinctive stiff-winged flight pattern, just above the water's surface. During the non-breeding season, they appear duller and exhibit more noticeable barring on the wings, which is most visible at close range. Juveniles display heavier barring above and buff edges to their wing feathers. The species can be differentiated from the similar Spotted Sandpiper by its darker legs and feet and the crisper wing pattern, especially in flight.

These birds are often found near freshwater sources, where they nest on the ground in close proximity to the water's edge.

The Common Sandpiper breeds across much of temperate and subtropical Europe and Asia. It is a migratory bird, wintering in Africa, southern Asia, and Australia. During migration, large numbers may congregate in stop-over locations such as Palau in Micronesia.

Common Sandpipers are typically solitary or found in small groups. They may form larger flocks during migration or at breeding season roosts but seldom join multispecies flocks.

When breeding, these birds nest on the ground near freshwater. A notable behavior is the young's ability to cling to a parent's body, being flown to safety when threatened.

The Spotted Sandpiper (A. macularia) is the most similar species, especially in non-breeding plumage. However, the Common Sandpiper's darker legs and more defined wing pattern in flight help distinguish it.

The Common Sandpiper forages by sight, picking up small food items such as insects, crustaceans, and other invertebrates from the ground or shallow water. It is also known to catch insects in flight.

The species is widespread and common, thus classified as Least Concern on the IUCN Red List. However, it is considered vulnerable in some Australian states. The Common Sandpiper is protected under the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA).
