28-9-2023 PARADOR, TERUEL - PANOPTES BLUE BUTTERFLY (Pseudophilotes panoptes)
28-9-2023 PARADOR, TERUEL - SOUTHERN GRIZZLED SKIPPER BUTTERFLY (Pyrgus malvoides)
The wingspan of this butterfly is 24–26 mm.
Pyrgus malvoides is distributed from Portugal and Spain via southern and central France, southern Switzerland (south of the main Alpine ridge) and Austria (Vorarlberg, Tyrol) to Italy and Istria.
According to previous knowledge, Pyrgus malvoides colonizes various fresh and above all moist habitats in the Alps if these have structures that are favorable to the microclimate, such as open ground on gravel, rocks, obstructions from cattle kicking or erosion, etc. A syntopic occurrence with Pyrgus malvae could not be determined so far. Because of the identification problems in the field, no sucking plants were noted. It is assumed that there are no essential differences to Pyrgus malvae here.
The known altitudinal distribution extends from 800 m to about 2000 m in Bavaria. It is found up to heights of 2500 m in the central Alps.
Adults are on wing from April to September. In Bavaria Pyrgus malvoides flies in one generation from around mid-May to mid-July. A second or even third generation per year, as described e.g. in Italy, was not observed in Bavaria.
The larvae feed on Potentilla, Agrimonia and Fragaria species, but primarily Potentilla erecta. It is reported from Switzerland that the caterpillars have been found on various cinquefoil species (Potentilla neumanniana [= tabernaemontani], Potentilla pusilla, Potentilla erecta) and have eaten Fragaria vesca during breeding.

27-9-2023 PLANS, ARAGON - QUEEN OF SPAIN FRITILLARY BUTTERFLY (Issoria lathonia)
This species is present almost throughout the year, with three or four successive generations. The eggs are laid separately on the underside of the leaves of the host plant. The larval cycle is exceptionally short. The pupation takes place among the low vegetation, between a few leaves united by silk. This species may overwinter at all larval stages.
Adults are strong flyers and fly from March to October. The heat-dependent caterpillars feed on Viola species (wild pansy or heartsease (Viola tricolor), field pansy (Viola arvensis), Viola canina, Viola odorata, Viola calcarata, Viola lutea, Viola biflora), lucerne (Medicago sativa), borage (Borago officinalis), Anchusa, Rubus and Onobrychis species.
In the dry regions Issoria lathonia carries out a seasonal vertical migration between hardy evergreen shrubs and small trees of plains and mountain fir pines, where it remains in summer to descend in autumn at low altitude.
Issoria lathonia is a medium-sized butterfly with a wingspan of 38–46 millimetres (1.5–1.8 in). The wings show a deep orange-violet background, with rounded black spots arranged in regular rows and suffused with greenish gray in the females. The underside of the hindwings is decorated with large pearly nacreous spots and it is crossed by a postdiscal row of black eyespots with pearly pupils. Some pearly spots also appear at the apex of the forewings.
The caterpillar can reach a length of 35 millimetres (1.4 in). It is grayish brown, with black spots, and relatively short brown spines with white tip, and a double row of dorsal white streaks. The suspended chrysalis is dark brown, with a large white saddle-shaped stain and some smaller ones of the same color, resembling a bird's dropping.
The imago is loosely similar to Speyeria aglaja, Fabriciana adippe and Brenthis daphne, which have the same orange color on the upperside of the wings, but show different markings and spots. Moreover, the underside of the hindwings does not have the large pearly spots characteristic of the Queen of Spain fritillary.
This migratory species is widespread in most of Europe, in North Africa, Canary Islands, and in the eastern Palearctic realm (Central Asia, Himalayas, Baluchistan, and Western China). These butterflies live in open areas, in dry lawns, agricultural wastelands and in extensive crops at altitudes between sea level and 2700 m.
27-9-2023 PLANS, ARAGON - BEARDED VULTURE (Gypaetus barbatus)
Tuesday, 26 September 2023
26-9-2023 MEDIANO, ARAGON - EUROPEAN STONECHAT (MALE) (Saxicola rubicola)
The European stonechat (Saxicola rubicola) is a small passerine bird that was formerly classed as a subspecies of the common stonechat. Long considered a member of the thrush family, Turdidae, genetic evidence has placed it and its relatives in the Old World flycatcher family, Muscicapidae.
26-9-2023 REVILLA, ARAGON - CATALONIA WALL LIZARD (Podarcis liolepis)
26-9-2023 REVILLA, ARAGON - ROCK GRAYLING BUTTERFLY (Hipparchia alcyone)
Hipparchia hermione, the rock grayling, is a butterfly of the family Nymphalidae. The species can be found in Central Europe, Southern Europe, Eastern Europe, North Africa, Anatolia and the Caucasus.
The wingspan is 27–34 millimetres (1.1–1.3 in).The ground colour is dark brown. There is a white submarginal band, bordered with an interrupted fringe and a large black ocellus at the apex of the forewing. The hindwing has a small ocellus with a very discrete pupil
The underside of the forewing is similar: brown with a white submarginal band and the black ocellus with white pupil at the apex, while the hindwing is marbled with brown and white with a broad white band. No sexual dimorphism.
Similar to Hipparchia fagi, but on the underside the deep dark basal area of both wings contrasts much more sharply with the light band, and the latter, which is almost pure white on the hindwing, contrasts again conspicuously with the broad dark distal margin. The conspicuousness of the pattern on the underside of the hindwing is especially noticeable in the male, but even in the duller coloured female the band on the hindwing beneath is still quite distinct, although sparsely irrorated with black.
It is smaller than fagi.
26-9-2023 REVILLA, ARAGON - WALLCREEPER (Tichodroma muraria)
The wallcreeper (Tichodroma muraria) is a small passerine bird found throughout the high mountains of the Palearctic from southern Europe to central China. It is the only extant member of both the genus Tichodroma and the family Tichodromidae.
The wallcreeper is a 15.5–17-centimetre (6.1–6.7 in) long bird, with a mass of 17–19 grams (0.60–0.67 oz). Its plumage is primarily blue-grey, with darker flight and tail feathers. Its most striking plumage feature, though, are its extraordinary crimson wings. Largely hidden when the wings are folded, this bright colouring covers most of the covert feathers, and the basal half of the primaries and secondaries. The subspecies T. m. nepalensis is slightly darker than the nominate race.
The wallcreeper is an insectivore, feeding on terrestrial invertebrates—primarily insects and spiders—gleaned from rock faces. It sometimes also chases flying insects in short sallies from a rock wall perch. Feeding birds move across a cliff face in short flights and quick hops, often with their wings partially spread.

25-9-2023 AINSA, ARAGON - BEARDED VULTURE (Gypaetus barbatus)
The bearded vulture population is thought to be in decline; in 2004, it was classified on the IUCN Red List as least concern but has been listed as near threatened since 2014. It lives and breeds on crags in high mountains in southern Europe, East Africa, the Indian subcontinent, Tibet, and the Caucasus.Females lay one or two eggs in mid-winter that hatch at the beginning of spring. The bearded vulture is the only known vertebrate whose diet consists of 70–90% bone.
This bird is 94–125 cm (37–49 in) long with a wingspan of 2.31–2.83 m (7 ft 7 in – 9 ft 3 in). It weighs 4.5–7.8 kg (9.9–17.2 lb), with the nominate race averaging 6.21 kg (13.7 lb) and G. b. meridionalis of Africa averaging 5.7 kg (13 lb). In Eurasia, vultures found around the Himalayas tend to be slightly larger than those from other mountain ranges. Females are slightly larger than males. It is essentially unmistakable with other vultures or indeed other birds in flight due to its long, narrow wings, with the wing chord measuring 71.5–91 cm (28.1–35.8 in), and long, wedge-shaped tail, which measures 42.7–52 cm (16.8–20.5 in) in length. The tail is longer than the width of the wing. The tarsus is relatively small for the bird's size, at 8.8–10 cm (3.5–3.9 in). The proportions of the species have been compared to a falcon, scaled to an enormous size.
Unlike most vultures, the bearded vulture does not have a bald head. This species is relatively small-headed, although its neck is powerful and thick. It has a generally elongated, slender shape, sometimes appearing bulkier due to the often hunched back of these birds. The gait on the ground is waddling and the feet are large and powerful. The adult is mostly dark gray, rusty, and whitish in color. It is grey-blue to grey-black above. The creamy-coloured forehead contrasts against a black band across the eyes and lores and bristles under the chin, which form a black beard that give the species its English name. Bearded vultures are variably orange or rust of plumage on their head, breast, and leg feathers, but this is actually cosmetic. This colouration may come from dust-bathing, rubbing mud on its body, or drinking mineral-rich waters. The tail feathers and wings are gray. The juvenile bird is dark black-brown over most of the body, with a buff-brown breast and takes five years to reach full maturity. The bearded vulture is silent, apart from shrill whistles in their breeding displays and a falcon-like cheek-acheek call made around the nest.
25-9-2023 AINSA, ARAGON - MALLOW SKIPPER BUTTERFLY (Carcharodus alceae)
Carcharodus alceae, commnly known as the mallow skipper, is a species of butterfly of the family Hesperiidae.
Carcharodus alceae has a wingspan of 28–32 mm. The background colour of the forewings is pinkish brown, with approximately square brown markings, short, white transverse stripes running from the edge and clear patches on the discal area. Hindwings are brownish or grey-brown, with some prominent brighter spots on the underside. Males are without hair tuft on forewings underside. Antennae have cherry brown tips.
The eggs are yellowish and hemispherical and the surface is covered with elongated warts, connected each other with low ribs. The egg has a prickly appearance. In the course of the development they turn red. The caterpillars can reach a length of about 23 millimetres (0.91 in). They are dark gray, covered with small white dots and short, white hairs. The head is black with yellow spots, separated by black stripes.
25-9-2023 LA PERDIDA, ARAGON - SCALLOPED OAK MOTH
The scalloped oak (Crocallis elinguaria) is a moth of the family Geometridae. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae.
This common species can be found from Europe to eastern Siberia.
This species inhabits a wide range of habitats, including mixed and deciduous forests, bushes, heaths, scrub, hedgerows, bogs, parks and gardens.
The wingspan is 32–46 mm. This is a distinctive species, usually with yellow-tan forewings with a broad orange-brown band and a pointed apex. Females are usually paler. There can be considerable variation, with the central band sometimes the same colour as the rest of the forewing, ranging from pale yellow to orange brown. Melanic forms are also known. There is always a blackish discal spot on the forewing in middle of band towards the costa. The thorax is hairy. The hindwings are plain whitish. Last instar caterpillars have a brownish or yellowish colouration. On the dorsum there is a dark brown line which is extended at the segment incisions. There are sometimes some dark spots or slashes on the sides. Characteristic are two small pointed warts on the eleventh segment. This species is rather similar to Crocallis albarracina. Prout describes some forma.

24-9-2023 CAMBRILS, TARRAGONA - YELLOW LEGGED GULL (Larus michahellis)
The breeding range is centred on the Mediterranean Sea. In North Africa, it is common in Morocco, Algeria and Tunisia and increasing in places. Recent breeding has occurred in Libya and Egypt. In the Middle East, a few breed in Israel, Palestine and Syria with larger numbers in Cyprus and Turkey. In Europe, there are colonies all along the Mediterranean coast, and also on the Atlantic islands and coasts north to Brittany and west to the Azores. It also breeds on the western side of the Black Sea; here it overlaps with the Caspian gull but there is a difference in habitat, with the yellow-legged gull preferring sea cliffs and the Caspian gull flatter shores. In recent decades birds have spread north into central and western Europe. One to four pairs have attempted to breed in southern England since 1995 (sometimes hybrid pairs with lesser black-backed gulls), though colonisation has been very slow.
24-9-2023 CAMBRILS, TARRAGONA - YELLOW LEGGED GULL (JUVENILE) (Larus michahellis)
The yellow-legged gull (Larus michahellis) is a large gull found in Europe, the Middle East and North Africa, which has only recently achieved wide recognition as a distinct species. It was formerly treated as a subspecies of either the Caspian gull L. cachinnans, or more broadly as a subspecies of the herring gull L. argentatus. The genus name is from Latin Larus which appears to have referred to a gull or other large seabird, and the species name honours the German zoologist Karl Michahelles.
It is now generally accepted that the yellow-legged gull is a full species, but until recently there was much disagreement. For example, British Birds magazine split the yellow-legged gull from the herring gull in 1993 but included the Caspian gull in the former, but the BOU in Great Britain retained the yellow-legged gull as a subspecies of the herring gull until 2007. DNA research, however, suggests that the yellow-legged gull is actually closest to the great black-backed gull L. marinus and the Armenian gull L. armenicus, while the Caspian gull is closer to the herring gull and the lesser black-backed gull L. fuscus, rather than being each other's closest relatives.

24-9-2023 REAL DE GANDIA, VALENCIA - LAMENTING GRASSHOPPER (Eyprepocnemis plorans)
The lamenting grasshopper (Eyprepocnemis plorans) has a name that sounds like they spend most of their time wondering about the love that never was. Instead, this insect is known to have a number of different forms, known as polymorphs, given its extra chromosomes. It is known for being a nervous species and also particularly good at flying.

23-9-2023 MONTE CORONA, VALENCIA - SPECKLED FOOTMAN MOTH (Coscinia cribraria)
Coscinia cribraria, the speckled footman, is a moth of the family Erebidae. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. It is found in Europe except the most northern parts; also in north-western Africa, Kazakhstan, Siberia, Mongolia, north-western and north-eastern China.
The wingspan is 30–35 mm. The moth flies from July to August depending on the location.
The larvae feed on various herbaceous plants, including Festuca, Calluna vulgaris and Plantago lanceolata.
23-9-2023 MONTE CORONA, VALENCIA - HOARY FOOTMAN MOTH (Eilema caniola)
Eilema caniola, the hoary footman, is a moth of the family Erebidae. The species was first described by Jacob Hübner in 1808.
This species can be found in North Africa, in western and southern Europe, in eastern Europe up to south-western Russia, in the Near East, in the eastern Palearctic realm, and in the Oriental realm. These thermophilic moths usually occur in urban areas and as a caterpillar on old walls, roofs, shingle beaches, and rocky areas.
The wingspan is 28–35 mm. It is almost the same in colouring as Eilema griseola and Eilema lurideola but the forewings are much smaller, the outer margin is oblique, only slightly excurved; the colour is much lighter, more yellowish grey, so that the pale yellow costal stripe is less prominent. Hindwings are very pale, scarcely darker at the costal margin, with the apex much more pointed than in the two species mentioned, with which it might be confounded.
23-9-2023 MONTE CORONA, VALENCIA - HALF EDGED WALL JUMPING SPIDER (Menemerus semilimbatus)
Menemerus semilimbatus are about 6.5–8.4 millimetres (0.26–0.33 in) long, the male being slightly smaller than the female. These fairly big jumping spiders are dorso-ventrally flattened and are covered with short dense, grayish-white hairs, with hairy whitish palps and a white band on the side margins of the carapace, showing also a small white, triangular marking in the middle. The eyes are large and forward-facing. The legs are light brown with darker rings and patches, while the abdomen is dorsally yellowish or grayish, with a characteristic pattern of several bright V-shaped markings. The females show a notch at the posterior edge of the epigyne and two oval depressions in the anterior half.
23-9-2023 MONTE CORONA, VALENCIA - MEDITERRANEAN KATYDID (Phaneroptera nana)
Phaneroptera nana, common name southern sickle bush-cricket, is a species in the family Tettigoniidae and subfamily Phaneropterinae. It has become an invasive species in California where it may be called the Mediterranean katydid.
This bush cricket is native to mainland Europe, the Near East and North Africa. The Indo-Malayan species Phaneropera subcarinata, described by Bolívar, is morphologically similar to P. nana, and was classified under the P. nana name by Carl Brunner von Wattenwyl. As an invasive species, it has spread to the San Francisco Bay Area and may be widespread in the Los Angeles Basin, with records of its presence in California dating from at least 1952. In addition, it has been recorded in South America and hypothesized in the Annals of Carnegie Museum to have spread via shipping.
It mainly inhabits sunny and dry habitats, especially shrubs and low branches of trees.
23-9-2023 MONTE CORONA, VALENCIA - PEARL MOTH (Dolicharthria bruguieralis)
Dolicharthria bruguieralis is a species of moth in the family Crambidae. It is found from France, Portugal, Spain, Italy, Croatia, Romania, Bulgaria, the Republic of Macedonia, Albania, Greece and Turkey, east to Japan and Taiwan. It is also found in Africa, including Morocco, Algeria and South Africa.
The wingspan is about 17 millimetres (0.67 in).
21-9-2023 MONTE CORONA, VALENCIA - BLUE ROCK THRUSH (FEMALE) (Monticola solitarius)
The Blue Rock Thrush is an usual inhabitant of cliffs and rocky slopes where it nests.
The adult male in summer has deep blue plumage overall, darker and browner on wings and tail.
Tail feathers are black with slate-blue edges on outer rectrices.
On the wings, the flight feathers are blackish with slate-blue edges, more or less extended.
The head is blue with blackish lores. The slender black bill is relatively long. The eyes are dark brown. Legs and feet are greyish-black to black.
The adult male in winter plumage shows duller plumage with grey to sandy-buff edged feathers. Wings and tail are darker, but with paler tips and edges.

20-9-2023 LAGUNA DE SILLA, ALBUFERA - BROAD SCARLET DRAGONFLY (MALE) (Crocothemis erythraea)
The scarlet dragonfly (Crocothemis erythraea) is a species of dragonfly in the family Libellulidae. Its common names include broad scarlet, common scarlet-darter, and scarlet darter.
The scarlet dragonfly is a common species in southern Europe and throughout Africa. It also occurs across western Asia as far as southern China. It is a very rare vagrant in Britain. Its first record in the country was at Hayle Kimbro Pool, The Lizard, Cornwall, on 7 August 1995. Since then there have been a few further records at scattered locations throughout Britain.
A wide range of both running and standing waters, except those that are shaded. Adults may be found some distance from water in habitats ranging from desert to open woodland; absent from dense forest.
Crocothemis erythraea can reach a length of 33–44 millimetres (1.3–1.7 in). These dragonflies haves a flattened and rather broad abdomen. The adult male scarlet dragonfly has a bright scarlet red, widened abdomen, with small amber patches at the bases of the hindwings. Also the veins on the leading edges of the wings are red. Females and immatures are yellow-brown and have a conspicuous pale stripe along the top of the thorax.
20-9-2023 REAL DE GANDIA, VALENCIA - LAMENTING GRASSHOPPER (Eyprepocnemis plorans)
The lamenting grasshopper (Eyprepocnemis plorans) has a name that sounds like they spend most of their time wondering about the love that never was. Instead, this insect is known to have a number of different forms, known as polymorphs, given its extra chromosomes. It is known for being a nervous species and also particularly good at flying.
The Lamenting grasshopper is not toxic and does not usually pose a threat to human health. There is no need to be overly concerned.
It can usually live for a year.
"Eyprepocnemis plorans" is native to much of Africa, parts of the Middle East such as Iran, and southern Europe, where it is present in southern Greece, southern Italy, Sicily, Sardinia and southern Spain. It seems to be expanding its range northwards in Italy, possibly as a result of putative climate change. It usually occurs in wetlands, reed beds, freshwater and salt marshes, riverside vegetation, coastal vegetation and man-made habitats. It appreciates vertical-growing stems such as reeds, and habitats with tall forbs mixed with lower-growing plants.
It eats green plants, especially grasses and grains.
Thursday, 21 September 2023
21-9-2023 MONTE CORONA, VALENCIA - TOAD CRAB SPIDER (Bassaniodes bufo)

This species is found in the Mediterranean.
21-9-2023 MONTE CORONA, VALENCIA - IBERIAN STRAW GRASSHOPPER (Euchorthippus chopardi)
Euchorthippus chopardi, the Iberian straw grasshopper, is a species of slant-faced grasshopper in the family Acrididae. It is found in Europe.
The IUCN conservation status of Euchorthippus chopardi is "LC", least concern, with no immediate threat to the species' survival. The IUCN status was assessed in 2015.
21-9-2023 MONTE CORONA, VALENCIA - THE COPPERY TAUPE (Charissa mucidaria)
20-9-2023 LAGUNA DE SILLA, ALBUFERA - LONG SKIMMER DRAGONFLY (MALE) (Orthetrum trinacria)

It was recently recorded in the Maltese Islands in 2003 and was recorded breeding on the island of Gozo in 2004. Its natural habitats are rivers, shrub-dominated wetlands, swamps, freshwater lakes, intermittent freshwater lakes, freshwater marshes, and intermittent freshwater marshes. Also breeding in Southern Spain (Murcia and Malaga Provinces) and the Canary Islands.
20-9-2023 CREU DE LONGA, ALBUFERA - GREY HERON (Ardea cinerea)
Standing at up to a metre tall and with a wingspan of between 155 and 195 centimetres, the grey heron is almost unmistakable. Adults have an orangey yellow, dagger shaped beak, a dark eye stripe which contrasts with their almost white head and neck, grey wings with dark outer edges and a small crest of feathers protruding from the back of their heads. They also have long spindly legs and hold these and their heads and necks close into their bodies during flight. For the most part, males and females look the same although the crest of feathers, which are known as Aigrets are slightly longer in breeding condition males.
Grey herons are mostly a waterside bird, found at all inland waterways, along the coast and much to the annoyance of koi and goldfish keepers, theyll frequently attempt to visit garden ponds. With this wetland preference, a lot of their diet is made up of fish and amphibians but they will also hunt away from the water and take small mammals, birds and insects. They catch their larger prey by surprise, stalking it, impaling it and then swallowing it whole.
When it comes to nesting, grey herons will often choose to nest communally in what is known as a heronry. This will usually be in clusters of large trees on islands or close to water and they will sometimes share their nesting areas with other fish eating birds such as great cormorants, spoonbills and egrets. From the age of two years onwards, each adult heron will attempt to find a mate from early spring onwards and once they are successful will begin the construction of a large twig platform nest. Once the nest is complete, each pair will produce between 3 and 5 greeney blue eggs at 2 day intervals. These measure 6cm in length and are incubated by both parents for 27 days from when the first or second is laid. This means that the chick hatch at intervals too and their can be a noticeable size difference between them. Both parents bring food back to the chicks in the nest and they grow rapidly, fledging at 50-55 days old. At this point the young are duller and scruffier looking versions of their parents and are still cared for away from the nest for a further 2 to 4 weeks until they are able to fend for themselves. Each pair will only nest once per year and after nesting they remain mostly solitary, only searching out a new mate the following spring.
There are currently an estimated 13,000 grey heron nests in the UK and 63,000 birds overwintering here. They are also found across most of Europe, Russia, northern Asia parts of Australasia and south Africa. They have a close and similar looking relative in the Americas called a great blue heron. Grey herons in the UK dont migrate and at some point outside of the breeding season they can be seen stood along a waterway or in a field all facing the same direction, and no one really know why they do this although it is thought it might be just for social interaction. They have an average lifespan of around five years but the oldest wild bird on record made it to 23 years of age.

20-9-2023 ULLAL DE BALDOVI, ALBUFERA - RED SWAMP CRAYFISH (Procambarus clarkii)
rocambarus clarkii, known variously as the red swamp crayfish, Louisiana crawfish or mudbug, is a species of cambarid crayfish native to freshwater bodies of northern Mexico, and southern and southeastern United States, but also introduced elsewhere (both in North America and other continents), where it is often an invasive pest.
P. clarkii is typically dark red, with long claws and head, small or no spines on the sides of its carapace just below the head, and rows of bright red bumps on the front and side of the first leg.
The native range of P. clarkii is from northern Mexico and far southeastern New Mexico, through the Gulf States to the Florida Panhandle, as well as inland north through the Mississippi Basin to southern Illinois and Ohio. It has also been introduced, sometimes deliberately, outside its natural range to countries in Asia, Africa, Europe and elsewhere in the Americas. In northern Europe, the populations are self-maintaining but not expanding, while in southern Europe, P. clarkii is multiplying and actively colonizing new territories at the expense of the native crayfish, Astacus astacus and Austropotamobius spp. Individuals are reported to be able to cross many miles of relatively dry ground, especially in wet seasons, although the aquarium trade and anglers may have hastened the spread in some areas (anglers using P. clarkii as fishing bait are thought to have introduced it to the state of Washington). Attempts have also been made to use P. clarkii as a biological control organism, to reduce levels of the snails involved in the lifecycle of schistosomiasis, leading to the dispersal of P. clarkii in, for instance, Kenya..
20-9-2023 ULLAL DE BALDOVI, ALBUFERA - CATTLE EGRET (Bubulcus ibis)
The cattle egret (Bubulcus ibis) is a cosmopolitan species of heron (family Ardeidae) found in the tropics, subtropics, and warm-temperate zones. It is the only member of the monotypic genus Bubulcus, although some authorities regard its two subspecies as full species, the western cattle egret and the eastern cattle egret. Despite the similarities in plumage to the egrets of the genus Egretta, it is more closely related to the herons of Ardea. Originally native to parts of Asia, Africa, and Europe, it has undergone a rapid expansion in its distribution and successfully colonised much of the rest of the world in the last century.
It is a white bird adorned with buff plumes in the breeding season. It nests in colonies, usually near bodies of water and often with other wading birds. The nest is a platform of sticks in trees or shrubs. Cattle egrets exploit drier and open habitats more than other heron species. Their feeding habitats include seasonally inundated grasslands, pastures, farmlands, wetlands, and rice paddies. They often accompany cattle or other large mammals, catching insect and small vertebrate prey disturbed by these animals. Some populations are migratory and others show postbreeding dispersal.
The adult cattle egret has few predators, but birds or mammals may raid its nests, and chicks may be lost to starvation, calcium deficiency, or disturbance from other large birds. This species maintains a special relationship with cattle, which extends to other large grazing mammals; wider human farming is believed to be a major cause of their suddenly expanded range. The cattle egret removes ticks and flies from cattle and consumes them. This benefits both species, but it has been implicated in the spread of tick-borne animal diseases.
