15-10-2001 SYDNEY, AUSTRALIA - SUPERB FAIRY WREN (MALE) (Malurus cyaneus)

The superb fairywren (Malurus cyaneus) is a passerine bird in the Australasian wren family, Maluridae, and is common and familiar across south-eastern Australia. It is a sedentary and territorial species, also exhibiting a high degree of sexual dimorphism; the male in breeding plumage has a striking bright blue forehead, ear coverts, mantle, and tail, with a black mask and black or dark blue throat. Non-breeding males, females and juveniles are predominantly grey-brown in colour; this gave the early impression that males were polygamous, as all dull-coloured birds were taken for females. Six subspecies groups are recognized: three larger and darker forms from Tasmania, Flinders and King Island respectively, and three smaller and paler forms from mainland Australia and Kangaroo Island.

Like other fairywrens, the superb fairywren is notable for several peculiar behavioural characteristics; the birds are socially monogamous and sexually promiscuous, meaning that although they form pairs between one male and one female, each partner will mate with other individuals and even assist in raising the young from such pairings. Male wrens pluck yellow petals and display them to females as part of a courtship display.

The superb fairywren can be found in almost any area that has at least a little dense undergrowth for shelter, including grasslands with scattered shrubs, moderately thick forest, woodland, heaths, and domestic gardens. It has adapted well to the urban environment and is common in suburban Sydney, Canberra, Melbourne and Brisbane. The superb fairywren eats mostly insects and supplements its diet with seeds.

15-10-2001 QUEENSLAND, AUSTRALIA - BEACH STONE CURLEW (Esacus magnirostris)

The beach stone-curlew (Esacus magnirostris) or beach thick-knee is a large, ground-dwelling bird that occurs in Australasia, the islands of South-east Asia. At 55 cm (22 in) and 1 kg (2.2 lb), it is one of the world's largest shorebirds.

It is less strictly nocturnal than most stone-curlews, and can sometimes be seen foraging by daylight, moving slowly and deliberately, with occasional short runs. It tends to be wary and fly off into the distance ahead of the observer, employing slow, rather stiff wingbeats..

The beach stone-curlew is classified as Near Threatened on the IUCN Red List of Threatened Species. In New South Wales, it is listed as critically endangered.

The beach stone-curlew is a resident of undisturbed open beaches, exposed reefs, mangroves, and tidal sand or mudflats over a large range, including coastal eastern Australia as far south as far eastern Victoria, the northern Australian coast and nearby islands, New Guinea, New Caledonia, Indonesia, Malaysia, and the Philippines. It is uncommon over most of its range, and rare south of Cairns.

The beach stone-curlew is 54-56 cm (21-22 in) long. At a mean of 1,032 g (2.275 lb) in males and 1,000 g (2.2 lb) in females, it is the heaviest living member of the Charadriiformes outside of the gull and skua families. They have black and white face patterning, yellow eyes and a grey-brown upper body.

15-10-2001 QUEENSLAND, AUSTRALIA - RED CAPPED PLOVER (Anarhynchus ruficapillus)

The red-capped plover (Anarhynchus ruficapillus), also known as the red-capped dotterel, is a small species of plover.

It breeds in Australia. This species is closely related to (and sometimes considered conspecific with) the Kentish plover, Javan plover, and white-fronted plover.

Red-capped plovers have a white forehead and underparts. Their upperparts are mainly grey-brown. Adult males have a rufous or reddish-brown crown and hindneck. Adult females have a paler rufous and grey-brown crown and hindneck, with a pale loreal stripe. The upperwing of Anarhynchus ruficapillus shows dark brown remiges (flight feathers) and primary covert feathers with a white wingbar in flight. Its length is 14–16 cm (5.5–6.3 in) and its wingspan is 27–34 cm (10.6–13.4 in); it weighs 35–40 g (1.2–1.4 oz).

Breeding plumage shows a red-brown crown and nape with black margins. Non-breeding plumage is duller and lacks the black margins.

The red-capped plover is widespread in Australia; it is a vagrant to New Zealand, although it bred there for some time in small numbers from 1950–1980. The species occupies a range of coastal and inland habitats, including estuaries, bays, beaches, sandflats, and mudflats; inland saline wetlands. It is also found in inland wetland areas with bare ground.

15-10-2001 QUEENSLAND, AUSTRALIA - EASTERN ROSELLA (Platycercus eximius)

The Eastern rosella (Platycercus eximius) is a colorfull parrot native to Australia and Tasmania. It is sometimes considered a subspecies of the Pale-headed rosella (P. adscitus).

The Eastern rosella has a red head and white cheeks. The beak is white, and the irises are brown. The upper breast is red, and the lower breast is yellow fading to pale green over the abdomen. The feathers of the back and shoulders are black and have yellowish or greenish margins giving rise to a scalloped appearance that varies slightly between the subspecies and the sexes. The wings and lateral tail feathers are bluish while the tail is dark green. The legs are grey. The female is similar to the male though duller in coloration and has an underwing stripe, which is not present in the adult male. Juveniles are duller than females and have an underwing stripe.

15-10-2001 QUEENSLAND, AUSTRALIA - REGENT BOWERBIRD (Sericulus chrysocephalus)

The regent bowerbird (Sericulus chrysocephalus) is a medium-sized, up to 25 cm long, sexually dimorphic bowerbird. The male bird is black with a golden orange-yellow crown, mantle and black-tipped wing feathers. It has yellow bill, black feet and yellow iris. The female is a brown bird with whitish or fawn markings, grey bill, black feet and crown. The name commemorates a prince regent of the United Kingdom.

The diet consists mainly of fruits, berries and insects.

All male bowerbirds build bowers, which can be simple ground clearings or elaborate structures, to attract female mates. Regent bowerbirds in particular are known to mix a muddy greyish blue or pea green "saliva paint" in their mouths which they use to decorate their bowers. The male builds an avenue-type bower consisting of two walls of sticks, decorated with shells, seeds, leaves and berries. Regents will sometimes use wads of greenish leaves as "paintbrushes" to help spread the substance, representing one of the few known instances of tools used by birds. The female builds a saucer-shaped nest made of twigs measuring 30 cm high and 15–20 cm wide often away from the bower.

An Australian endemic, the regent bowerbird is distributed to rainforests and margins of eastern Australia, from central Queensland to New South Wales.

A rare natural intergeneric hybrid between the regent bowerbird and the satin bowerbird is known as Rawnsley's bowerbird.

15-10-2001 QUEENSLAND, AUSTRALIA - GALAH (Eolophus roseicapilla)

The galah (/ɡəˈlɑː/; Eolophus roseicapilla), less commonly known as the pink and grey cockatoo, galah cockatoo, or rose-breasted cockatoo, is an Australian species of cockatoo and the only member of the genus Eolophus. The galah is adapted to a wide variety of modified and unmodified habitats and is one of Australia's most abundant and widespread bird species.

The galah can be found throughout Australia and is absent only from the driest areas and the far north of Cape York Peninsula. The galah has been introduced to Tasmania through anthropogenic means and no sightings were made prior to 1848. A large population expansion occurred in the 1960s following many escapees from captivity. It is common in metropolitan areas, such as Adelaide, Perth, and Melbourne, and abundant in open habitats that offer at least some scattered trees for shelter. It is common in all habitats in its range except for dense forests, especially those with high rainfall.

While it is mostly found in inland areas, the galah is rapidly colonising coastal regions. The changes brought by European settlement, which have been disastrous for many species, have been highly beneficial for the galah, because of the clearing of forests in fertile areas and the provision of stock-watering points in arid zones.

The galah was also introduced to New Zealand in the latter part of the 20th century, becoming established in the South Auckland area.

14-10-2001 QUEENSLAND, AUSTRALIA - PINK COCKATOO (Cacatua leadbeateri)

The pink cockatoo (Cacatua leadbeateri), also known as Major Mitchell's cockatoo or Leadbeater's cockatoo, is a medium-sized cockatoo that inhabits arid and semiarid inland areas across Australia, with the exception of the north-east.

The bird reaches sexual maturity around 3–4 years old. The oldest recorded pink cockatoo died at 83 years old.

In contrast to those of the galah, populations of pink cockatoos have declined rather than increased as a result of man-made changes to the arid interior of Australia. Where galahs readily occupy cleared and part-cleared land, pink cockatoos require extensive woodlands, particularly favouring conifers (Callitris spp.), sheoak (Allocasuarina spp.) and eucalypts. Unlike other cockatoos, pink cockatoo pairs will not nest close to one another, so they cannot tolerate fragmented, partly cleared habitats, and their range is contracting.

In the Mallee region of Victoria where the galah and pink cockatoo can be found to be nesting in the same area, the two species have interbred and produced hybridised offspring occasionally.

The pink cockatoo is usually found in pairs or small groups, and feeds both on the ground and in trees.

14-10-2001 QUEENSLAND, AUSTRALIA - FLAME ROBIN (Petroica phoenicea)

The flame robin (Petroica phoenicea) is a small passerine bird native to Australia. It is a moderately common resident of the coolest parts of south-eastern Australia, including Tasmania. Like the other two red-breasted Petroica robins—the scarlet robin and the red-capped robin—it is often simply called the robin redbreast. Like many brightly coloured robins of the Petroicidae, it is sexually dimorphic. Measuring 12–14 cm (4.7–5.5 in) long, the flame robin has dark brown eyes and a small thin black bill. The male has a brilliant orange-red chest and throat, and a white patch on the forehead above the bill. Its upper parts are iron-grey with white bars, and its tail black with white tips. Female coloration is a muted grey-brown. Its song has been described as the most musical of its genus.

The position of the flame robin and its Australian relatives on the passerine family tree is unclear; the Petroicidae are not closely related to either the European or American robins, but appear to be an early offshoot of the Passerida group of songbirds. The flame robin is predominantly insectivorous, pouncing on prey from a perch in a tree, or foraging on the ground. A territorial bird, the flame robin employs song and plumage displays to mark out and defend its territory. It is classified by BirdLife International as least concern.

10-10-2000 SYDNEY, AUSTRALIA - BLUE WINGED KOOKABURRA (Dacelo leachii)

The blue-winged kookaburra (Dacelo leachii) is a large kingfisher, slightly smaller than its cousin, the laughing kookaburra. It boasts a cream-colored plumage with brownish bars, blue wings, and a blue rump. The male is distinguished by its blue tail, while the female's tail is rufous with blackish bars.

Adults measure 38 to 42 cm in length and weigh between 260 to 330 grams. They lack the dark mask of the laughing kookaburra, have more blue in the wing, and striking white eyes. The bill is quite heavy. Juveniles can be identified by their more pronounced brown bars and marks, and their eyes are brown for the first two years.

This species is found in open savannah woodland, Melaleuca swamps, and farmlands, including sugarcane plantations.

The blue-winged kookaburra's range extends from southern New Guinea and northern Australia to Brisbane in southern Queensland, across the Top End, and down the Western Australian coast as far as Shark Bay.

They live in family groups of up to 12 individuals and are known for their maniacal cackling or barking calls.

The call of the blue-winged kookaburra is a distinctive and loud cackle or barking sound.

A cooperative breeder, the blue-winged kookaburra nests in tree hollows, with a breeding pair assisted by helper birds. They lay three to four white, slightly shiny eggs, and chicks are altricial, requiring extensive care post-hatching.

Their diet varies seasonally, including insects, lizards, frogs, crayfish, scorpions, spiders, fish, earthworms, small birds, and rodents. They are opportunistic and may even snatch insects fleeing from bushfires.

The blue-winged kookaburra is listed as Least Concern on the IUCN Red List of Threatened Species. However, they face predation from red goshawks and rufous owls, and adults are at risk of vehicle collisions. Nests may be raided by olive pythons, quolls, and goannas.

10-10-2001 SYDNEY, AUSTRALIA - EASTERN CATTLE EGRET (Bubulcus ibis ssp. coromandus)

The Eastern Cattle Egret, Bubulcus coromandus, is a member of the heron family Ardeidae, displaying a stout build with a wingspan ranging from 88 to 96 centimeters. It is characterized by its white plumage, which during the breeding season is adorned with buff plumes, and a yellow bill and greyish-yellow legs. The breeding adult is distinguished by its golden nuptial plumes and the buff coloration extending to the cheeks and throat.

This species can be identified by its relatively short, thick neck, sturdy bill, and hunched posture. The non-breeding adult is predominantly white with a yellow bill. During breeding, the buff on the head extends to the cheeks and throat, and the plumes take on a more golden hue. The bill and tarsus are longer than those of its western counterpart, and it is generally smaller with shorter wings.

The Eastern Cattle Egret favors drier and open habitats more than other heron species. Its preferred environments include seasonally inundated grasslands, pastures, farmlands, wetlands, and rice paddies.

Native to southern and eastern Asia, and Australasia, this species has expanded its range remarkably, partly due to its symbiotic relationship with cattle and other large grazing mammals. It has established itself in the north and east of Australia and regularly visits New Zealand.

The Eastern Cattle Egret is often seen in the company of cattle or other large mammals, taking advantage of the insects and small vertebrates these animals disturb. Some populations are migratory, while others disperse after breeding, showing a remarkable adaptability in their movements.

10-10-2001 BLUE MOUNTAINS NSW, AUSTRALIA - EASTERN GREY KANGAROO (Macropus giganteus)

The eastern grey kangaroo (Macropus giganteus: gigantic large-foot; also great grey kangaroo or forester kangaroo) is a marsupial found in the eastern third of Australia, with a population of several million. Although a large M. giganteus kangaroo male can typically weigh up to 69 kg (152 lb) and have a length of well over 2 m (6 ft 7 in),the scientific name is misleading as the red kangaroo of the semi-arid inland is larger, weighing up to 90 kg (200 lb).

The eastern grey kangaroo was described by George Shaw in 1790 as Macropus giganteus.

Although the red is better known, the eastern grey is the kangaroo most often encountered in Australia, due to its adaptability. Few Australians visit the arid interior of the continent, while many live in and around the major cities of the southern and eastern coast, from where it is usually only a short drive to the remaining pockets of near-city bushland where kangaroos can be found without much difficulty. The eastern grey prefers open grassland with areas of bush for daytime shelter and mainly inhabits the wetter parts of Australia. It also inhabits coastal areas, woodlands, sub-tropical forests, mountain forests, and inland scrubs.

Like all kangaroos, it is mainly nocturnal and crepuscular, and is mostly seen early in the morning, or as the light starts to fade in the evening. In the middle of the day, kangaroos rest in the cover of the woodlands and eat there but then come out in the open to feed on the grasslands in large numbers.The eastern grey kangaroo mainly graze a wide variety of grasses[ compared to other species (e.g. the red kangaroo) that also include significant amounts of shrubs in their diet.

Eastern grey kangaroos are gregarious and form open-membership groups. The groups contain an average of three individuals. Smaller groups join to graze in preferred foraging areas, and to rest in large groups around the middle of the day. They exist in a dominance hierarchy and the dominant individuals gain access to better sources of food and areas of shade. However, kangaroos are not territorial. Eastern grey kangaroos adjust their behaviour in relation to the risk of predation with reproductive females, individuals on the periphery of the group and individuals in groups far from cover being the most vigilant. Vigilance in individual kangaroos does not seem to significantly decrease when the size of the group increases. However, there is a tendency for the proportion of individuals on the periphery of the group to decline as group size increases. The open membership of the group allows more kangaroos to join and thus provide more buffers against predators.

10-10-2001 AUSTRALIA - KOALA BEAR (Phascolarctos cinereus)

The koala or, inaccurately, koala bear (Phascolarctos cinereus), is an arboreal herbivorous marsupial native to Australia. It is the only extant representative of the family Phascolarctidae and its closest living relatives are the wombats. The koala is found in coastal areas of the mainland's eastern and southern regions, inhabiting Queensland, New South Wales, Victoria, and South Australia. It is easily recognisable by its stout, tailless body and large head with round, fluffy ears and large, spoon-shaped nose. The koala has a body length of 60–85 cm (24–33 in) and weighs 4–15 kg (9–33 lb). Fur colour ranges from silver grey to chocolate brown. Koalas from the northern populations are typically smaller and lighter in colour than their counterparts further south. These populations possibly are separate subspecies, but this is disputed.

The koala's range covers roughly 1,000,000 km2 (390,000 sq mi), and 30 ecoregions. It ranges throughout mainland eastern and southeastern Australia, including the states of Queensland, New South Wales, Victoria, and South Australia. The koala was introduced to several nearby islands. The population on Magnetic Island represents the northern limit of its range.

Fossil evidence shows that the koala's range stretched as far west as southwestern Western Australia during the late Pleistocene. They were likely driven to extinction in these areas by environmental changes and hunting by Indigenous Australians.  Koalas were introduced to Western Australia at Yanchep in 1938 but that population was reduced to 4 individuals by 2022. Koalas can be found in both tropical and temperate habitats ranging from dense woodlands to more spaced-out forests. In semi-arid climates, they prefer riparian habitats, where nearby streams and creeks provide refuge during times of drought and extreme heat.

10-10-2001 BLUE MOUNTAINS NSW, AUSTRALIA - AUSTRALIAN GOLDEN WHISTLER (Pachycephala pectoralis)

The Australian golden whistler (Pachycephala pectoralis) or golden whistler, is a species of passerine bird in the family Pachycephalidae. It is found in forest, woodland, mallee, mangrove and scrub in Australia (except the interior and most of the north). Most populations are resident, but some in south-eastern Australia migrate north during the winter. 

Its taxonomy is highly complex and remains a matter of dispute, with some authorities including as many as 59 subspecies of the golden whistler (one of the highest numbers of subspecies in any bird), while others treat several of these as separate species.

The Australian golden whistler can be found in almost any wooded habitat, especially dense forests. It eats berries, insects, spiders, and other small arthropods. They usually feed alone and obtain food from the lower to middle tree level, or they may alternatively take part in mixed-species feeding flocks.

This species breeds between September and January. Male and female both work on the nest, which is a shallow bowl made of twigs, grass, and bark, and bound together with spider web. Only one brood is raised per season and both birds share incubation and care of young. Eggs hatch 15 days after they are laid and the young leave the nest after 12 days.

1-10-2001 SYDNEY, AUSTRALIA - LAUGHING KOOKABURRA (Dacelo novaeguineae)

The Laughing Kookaburra (Dacelo novaeguineae) is a robust member of the kingfisher family, known for its iconic laughter-like call. It has a white or cream-colored head adorned with a dark brown eye-stripe, while its upperparts are predominantly dark brown with a distinctive mottled light-blue patch on the wing coverts. The underparts are cream-white, and the tail is barred with rufous and black. Both male and female exhibit similar plumage.

This largest kingfisher species can be identified by its hefty bill, prominent brown eyes, and the unique pattern of its plumage. The male and female are similar in appearance, though the female is generally larger. The heavy bill is black on top and bone-colored on the bottom, and the bird has a dark eye-stripe that sets it apart from the blue-winged kookaburra.

The Laughing Kookaburra is found in a variety of habitats including dry eucalypt forests, woodlands, city parks, and gardens. It requires tree holes for nesting and is often seen in areas where the understory is open or grassy.

Native to eastern mainland Australia, the species has been introduced to parts of New Zealand, Tasmania, and Western Australia. It occupies territories throughout the year and is considered sedentary.

Laughing Kookaburras live in family groups, defending their territories with their laughter-like calls. They are monogamous, often retaining the same partner for life, and may be accompanied by offspring from previous years who assist in territory defense and raising young.

The bird's call is a distinctive laugh, used to establish territory and often performed in chorus at dawn and dusk. The call is a complex production, with the bird capable of producing two frequencies at once. It is a learned behavior, with young birds taught by the breeding pair.

1-10 2001 SYDNEY, AUSTRALIA - SHORT BEAKED ECHIDNA (Tachyglossus aculeatus)

The short-beaked echidna (Tachyglossus aculeatus), also called the short-nosed echidna, is one of four living species of echidna, and the only member of the genus Tachyglossus, from Ancient Greek ταχύς (takhús), meaning "fast", and γλῶσσα (glôssa), meaning "tongue". It is covered in fur and spines and has a distinctive snout and a specialised tongue, which it uses to catch its insect prey at a great speed. Like the other extant monotremes, the short-beaked echidna lays eggs; the monotremes are the only living group of mammals to do so.

The short-beaked echidna has extremely strong front limbs and claws, which allow it to burrow quickly with great power. As it needs to be able to survive underground, it has a significant tolerance to high levels of carbon dioxide and low levels of oxygen. It has no weapons or fighting ability but deters predators by curling into a ball and protecting itself with its spines. It cannot sweat or deal well with heat, so it tends to avoid daytime activity in hot weather. It can swim if needed. The snout has mechanoreceptors and electroreceptors that help the echidna to detect its surroundings.

During the Australian winter, it goes into deep torpor and hibernation, reducing its metabolism to save energy. As the temperature increases, it emerges to mate. Female echidnas lay one egg a year and the mating period is the only time the otherwise solitary animals meet one another; the male has no further contact with the female or his offspring after mating. A newborn echidna is the size of a grape but grows rapidly on its mother's milk, which is very rich in nutrients. By seven weeks baby echidnas grow too large and spiky to stay in the pouch and are expelled into the mother's burrow. At around six months they leave and have no more contact with their mothers.

The species is found throughout Australia, where it is the most widespread native mammal, and in coastal and highland regions of eastern New Guinea, where it is known as the mungwe in the Daribi and Chimbu languages. It is not threatened with extinction, but human activities, such as hunting, habitat destruction, and the introduction of foreign predatory species and parasites, have reduced its abundance in Australia.

1-10-2001 SYDNEY, AUSTRALIA - SOUTHERN HAIRY NOSED WOMBAT (Lasiorhinus latifrons)

The southern hairy-nosed wombat (Lasiorhinus latifrons ) is one of three extant species of wombats. It is found in scattered areas of semiarid scrub and mallee from the eastern Nullarbor Plain to the New South Wales border area. It is the smallest of all three wombat species. The young often do not survive dry seasons. It is the state animal of South Australia.

Among the oldest southern hairy-nosed wombats ever documented were a male and a female from Brookfield Zoo just outside Chicago. Their names were Carver, who lived to be 34, and his mother, Vicky, who lived to be 24. In South Australia in 2010, a domesticated wombat named Wally was also reported as having reached the age of 34. Hamlet, a wombat at the Toronto Zoo, similarly died at age 34.

Southern hairy-nosed wombat is a clumsy and plump marsupial with a charming face, large nose and small, bright eyes. Due to having adapted to harsh environment and a specific lifestyle, this animal is able to live on its nutrient-poor diet of grasses. One of 3 wombat species, this animal is distinguished from other 2 species of the family by relatively smaller body, longer ears, more reddish fur as well as shorter and more pointed muzzle, exhibiting white hairs around the nose.

1-4-1999 IGUAZU, ARGENTINA - SURUCURA TROGON (Trogon surrucura)

The Surucua trogon (Trogon surrucura) is a species of bird in the family Trogonidae, the quetzals and trogons. It is found in Argentina, Brazil, Paraguay, and Uruguay.

The nominate subspecies of Surucua trogon is found from eastern Paraguay and northeastern Argentina east into Uruguay and in Brazil as far north as southeastern Tocantins. T. s. aurantius has a more restricted range in east central and eastern Brazil from Bahia south to São Paulo state. They inhabit the mid levels of primary and well-developed secondary forest and semideciduous woodland. T. s. aurantius often associates with bamboo. T. s. surrucura occurs as high as 1,150 m (3,800 ft) in Bahia, 1,550 m (5,100 ft) in Minas Gerais, and higher still in Rio de Janeiro state. T. s. aurantius occurs up to about 2,000 m (6,600 ft). 

1-4-1999 IGUAZU, ARGENTINA - GREEN HEADED TANAGER

The green-headed tanager (Tangara seledon) is a brightly colored bird found in the Atlantic forest in south-eastern Brazil, far eastern Paraguay, and far north-eastern Argentina (Misiones only).

As other members of the genus Tangara, it is a small colorful bird, measuring an average of 13.5 centimeters (5.3 in) and a mass of 18g (0.6 oz). The green-headed Tanager has a greenish or bluish head, black on the back, and a contrastingly colored, orange or red rump. Females and juvenile birds have similar, though duller coloration. While essentially a bird of humid forests, it is also common in orchards and parks, where it moves through the canopy, making itself inconspicuous, as its apparently flashy blue-green coloration camouflages it well amongst the foliage. 

1-4-1999 IGUAZU, ARGENTINA - SPOT BILLED TOUCANET (Selenidera maculirostris)

The spot-billed toucanet (Selenidera maculirostris) is a near-passerine bird in the toucan family Ramphastidae. It is found in Argentina, Brazil, and Paraguay.

The spot-billed toucanet is 33 to 37 cm (13 to 15 in) long and weighs 137 to 193 g (4.8 to 6.8 oz). Males and females have the same bill pattern but the female's bill is shorter. The bill has a thin vertical black line at its base. The bill is mostly ivory at the base to greenish-yellow at the tip. The middle of the culmen is black, the maxilla has three to five vertical black stripes, and the mandible has a black patch near the end. Both sexes have bare green-yellow to blue skin arond the eye and a golden-yellow tuft of feathers behind it; both are paler in the female. Adult males have a black head, nape, chin, throat, and belly. Their upperparts are green with a yellow band on the lower neck. Their tail is green with chestnut tips on the central three pairs of feathers. Their flanks are yellow and their undertail coverts are red. Females have chestnut to cinnamon-rufous where the male has black. Immatures are duller overall, usually without a yellow band on the back, and their bill's pattern is not sharp.

 

1-4-1999 IGUAZU, ARGENTINA - INGRAM'S SQUIRREL (Sciurus brasiliensis ssp. ingrami)

Sciurus brasiliensis ingramiSciurus brasiliensis ingrami (also classified as Sciurus ingrami or Guerlinguetus brasiliensis ingrami) is a subspecies of the Brazilian squirrel. It is widely known by the common name Ingram's squirrel and is locally referred to as the serelepe or caxinguelê in Brazil, and the ardilla misionera or ardilla gris in Argentina.

Taxonomy & ClassificationTaxon

 Debate: Taxonomists place it either as a distinct species (Sciurus ingrami), a subspecies of the Guianan squirrel (Sciurus aestuans), or a subspecies of the Brazilian squirrel (Sciurus brasiliensis).

Alternative Genus: Modern Neotropical mammal revisions frequently assign it to the genus Guerlinguetus.Habitat & DistributionGeographic Range: It is native to South America, thriving along the Atlantic coast of Brazil (from the state of Espírito Santo down to Rio Grande do Sul) and extending into the Misiones Province of northeastern Argentina.

Ecosystems: It primarily inhabits the Atlantic Forest Biome, especially moist highland forests dominated by the Paraná pine (Araucaria angustifolia).

Adaptability: While highly arboreal and dependent on tree cover, it is opportunistic and easily adapts to secondary forests, agricultural areas, urban parks, and botanical gardens.

Diet & BehaviorPrimary Diet: The squirrel subsists heavily on hard nuts and palm fruits, particularly the nuts of the Syagrus romanzoffiana (queen palm) and seeds of the Araucaria pine. It occasionally supplements its diet with insects, bird eggs, and small vertebrates.

Activity Patterns: It is a strictly diurnal rodent with bimodal activity peaks—meaning it is most active during the early morning and late afternoon.

Social Structure: Typically solitary and highly territorial. However, individuals have been observed temporarily joining forces to "mob" and drive away predators, such as the margay (a small predatory cat).

Movement: It is incredibly agile, sprinting down vertical tree trunks headfirst and leaping massive gaps between canopy branches while using its bushy tail as a counterbalance.

1-4-1999 IGUAZU, ARGENTINA - SOUTHERN MONARCH BUTTERFLY (Danaus erippus)

Danaus erippus, the southern monarch, is a milkweed butterfly (subfamily Danainae) in the family Nymphalidae. It is one of the best known butterflies in South America. Its genome is nearly identical to D. plexippus, but the two are incompatible, and therefore considered separate species.

Though, not as well known as the eastern North American monarch migratory phenomenon, it has been observed to move in a consistent spring/autumn manner by flying south in the autumn towards colder latitudes for the winter.Massive overwintering roosts have not yet been found.

1-4-1999 IGUAZU, ARGENTINA - PLUSH CRESTED JAY (Cyanocorax chrysops)

The plush-crested jay (Cyanocorax chrysops) is a jay of the family Corvidae (which includes the crows and their many allies). It is found in central-southern South America: in southwestern Brazil, Bolivia, Paraguay, Uruguay, and northeastern Argentina, including southern regions of the Amazon Basin river systems bordering the Pantanal.

It is an elegant medium-sized bird, dark plumaged with a cream-yellow breast; the bulky tail is also cream colored, top and underneath, for the lower half.

The range of the plush-crested jay extends from the Southern Region, Brazil with Uruguay and approaches the South Atlantic coast, but avoids the coast, approximating a 400 to 150 km coastal strip; the coastal-inland range extends 3500 km from São Paulo south to Rio Grande do Sul bordering Uruguay. The inland range continues in northwestern Uruguay and extends northwest through northern Argentina, Paraguay–Bolivia, and through the Pantanal at the southern Cerrado; the range extends in two arms, to the northwest to northern Bolivia, and northeastwards to headwaters of the Amazon Basin Tapajós River.

In the Amazon Basin, central Bolivia is the northwest range limit, the headwater tributaries to the north-northeast flowing Madeira River; the next range skips the Guaporé River, (a northwest-flowing tributary to the Madeira), eastwards on the Brazil–Bolivia border, and is next found at the headwaters of the Tapajós River, and joins on the east the extreme headwaters of the Xingu River.

A disjunct range occurs downstream on the Tapajós and east towards the Xingu River, a block 850 by 750 kilometres (530 mi × 470 mi). Two other localized populations occur in the Amazon Basin, one on the Amazon River, the other on the downstream Madeira River. 

1-4-1999 IGUAZU, ARGENTINA - GUIRA CUCKOO (Guira guira)

The guira cuckoo (Guira guira) is a gregarious bird found widely in open and semi-open habitats of northeastern, eastern and southern Brazil, Uruguay, Paraguay, Bolivia, and northeastern Argentina. It is the only species placed in the genus Guira.

The guira cuckoo is a bird of open habitats such as pastures and wetlands, and its range has expanded significantly due to deforestation. Within its distribution, it is commonly seen in suburban parks and gardens.

Like the related squirrel cuckoo, the guira cuckoo is not a particularly adept flier, and usually flies only for short distances. It is often seen gliding or hopping from one perch to another while vocalizating loudly.

Although it is primarily an arboreal bird, it is often seen foraging on the ground, sometimes alone but often in flocks of up to 18 individuals. It is sometimes seen with other birds whose behaviour is similar, such as the smooth-billed ani. Unlike many of the Old World cuckoos, the guira cuckoo does not practice brood parasitism or kleptoparasitism. 

1-4-1999 IGUAZU, ARGENTINA - BLUE NAPED CHLOROPHONIA

The blue-naped chlorophonia (Chlorophonia cyanea) is a colourful South American species of bird in the family Fringillidae; it was formerly placed in the Thraupidae. It is generally fairly common.

A small, plump, mainly green bird. The underparts are yellow, and the mantle/lower nape, rump and eye-ring are blue. Some subspecies have a yellow frontlet. Females are duller than the males, with underparts more greenish-yellow and less blue to the mantle/lower nape.

Its distribution is highly disjunct, with population associated with the Atlantic Forest in south-eastern Brazil, eastern Paraguay and north-eastern Argentina, the Andes from Bolivia in south to Venezuela in north, the Perijá and Santa Marta Mountains, the Venezuelan Coastal Range, and the Tepuis. All populations are associated with humid forest, but locally it also occurs in nearby gardens and parks (especially in the Atlantic Forest region). Most populations are found in subtropical highlands, but it occurs down to near sea level in the Atlantic Forest region.
