The killer whale or orca (Orcinus orca) is a toothed whale belonging to the oceanic dolphin family, of which it is the largest member. Killer whales are found in all oceans, from Arctic and Antarctic regions to tropical seas. Killer whales have a diverse diet, although individual populations often specialise in particular types of prey. Some feed exclusively on fish, while others hunt marine mammals such as seals and dolphins. They have been known to attack baleen whale calves, and even adult whales. Killer whales are apex predators, as there is no animal which preys on them.

 

Killer whales are highly social; some populations are composed of matrilineal family groups (pods) which are the most stable of any animal species. Their sophisticated hunting techniques and vocal behaviours, which are often specific to a particular group and passed across generations, have been described as manifestations of animal culture.

 

The IUCN (International Union for the Conservation of Nature) currently assesses the orca's conservation status as data deficient because of the likelihood that two or more killer whale types are separate species. Some local populations are considered threatened or endangered due to prey depletion, habitat loss, pollution (by PCBs), capture for marine mammal parks, and conflicts with human fisheries. In late 2005, the Southern Resident Killer Whales, the population that inhabits British Columbia and Washington state waters, were placed on the U.S. Endangered Species list.

 

Wild killer whales are not considered a threat to humans, but there have been cases of captive orcas killing or injuring their handlers at marine theme parks. Killer whales feature strongly in the mythologies of indigenous cultures, with their reputation ranging from being the souls of humans to merciless killers.

 

A typical killer whale distinctively bears a black back, white chest and sides, and a white patch above and behind the eye. Calves are born with a yellowish or orange tint, which fades to white. It has a heavy and robust body with a large dorsal fin up to 1.8 m (5.9 ft) tall. Behind the fin, it has a dark grey "saddle patch" across the back. Antarctic killer whales may have pale grey to nearly white backs. Adult killer whales are very distinctive and are not usually confused with any other sea creature. When seen from a distance, juveniles can be confused with other cetacean species, such as the false killer whale or Risso's dolphin. The killer whale's teeth are very strong and its jaws exert a powerful grip; the upper teeth fall into the gaps between the lower teeth when the mouth is closed. The front teeth are inclined slightly forward and outward, thus allowing the killer whale to withstand powerful jerking movements from its prey while the middle and back teeth hold it firmly in place.

 

Killer whales are the largest extant members of the dolphin family. Males typically range from 6 to 8 metres (20 to 26 ft) long and weigh in excess of 6 tonnes (5.9 long tons; 6.6 short tons). Females are smaller, generally ranging from 5 to 7 m (16 to 23 ft) and weighing about 3 to 4 tonnes (3.0 to 3.9 long tons; 3.3 to 4.4 short tons). The largest male killer whale on record was 9.8 m (32 ft), weighing 10 tonnes (9.8 long tons; 11 short tons), while the largest female was 8.5 m (28 ft), weighing 7.5 tonnes (7.4 long tons; 8.3 short tons). Calves at birth weigh about 180 kg (400 lb) and are about 2.4 m (7.9 ft) long. The killer whale's large size and strength make it among the fastest marine mammals, able to reach speeds in excess of 56 km/h (30 kn). The skeleton of the killer whale is of the typical delphinid structure, but is more robust. Its integument, unlike that of most other dolphin species, is characterised by a well-developed dermal layer with a dense network of fascicles of collagen fibers.

 

Killer whale pectoral fins, analogous to forelimbs, are large and rounded, resembling paddles. Males have significantly larger pectoral fins than females. At about 1.8 m (5.9 ft) the male's dorsal fin is more than twice the size of the female's and is more of a triangular shape—a tall, elongated isosceles triangle—whereas hers is shorter and more curved. Males and females also have different patterns of black and white skin in their genital areas. Sexual dimorphism is also apparent in the skull; adult males have longer lower jaws than females, and have larger occipital crests.

 

An individual killer whale can often be identified from its dorsal fin and saddle patch. Variations such as nicks, scratches, and tears on the dorsal fin and the pattern of white or grey in the saddle patch are unique. Published directories contain identifying photographs and names for hundreds of North Pacific animals. Photographic identification has enabled the local population of killer whales to be counted each year rather than estimated, and has enabled great insight into lifecycles and social structures.

 

Occasionally a killer whale is white; they have been spotted in the northern Bering Sea and around St. Lawrence Island, and near the Russian coast. In February 2008, a white killer whale was photographed 3.2 km (2.0 mi) off Kanaga Volcano in the Aleutian Islands. In 2010, the Far East Russia Orca Project (FEROP), co-founded and co-directed by Alexander M. Burdin and Erich Hoyt, filmed an adult male nicknamed Iceberg .

 

Killer whales have good eyesight above and below the water, excellent hearing, and a good sense of touch. They have exceptionally sophisticated echolocation abilities, detecting the location and characteristics of prey and other objects in their environments by emitting clicks and listening for echoes,[78] as do other members of the dolphin family.

 

The mean body temperature of the orca is 36 to 38 °C (97 to 100 °F). Like most marine mammals, orcas have a layer of insulating blubber ranging from 7.6 to 10 cm (3.0 to 3.9 in) thick beneath its skin.

 

The heart beats at a rate of about 60 beats/min when the orca is at the surface, dropping to 30 beats/min when submerged.

Black kite uses fire by Su_G': entry in Spoonflower's 'Birds of Prey Wallpaper' Design Challenge. © Su Schaefer 2023

 

My design features the Black Kite, a tool-using Australian bird that spreads fire to hunt prey. Aboriginal traditions, across multiple groups in different areas, portray birds of prey as animals which carry fire… and field research has now confirmed this for black kite, brown falcon. Some say people learned from birds. For more, see sevenages.org/environmental-issues/birds-of-prey-in-austr...

Sorry that the new voting system still (sigh) has bugs... www.spoonflower.com/design-challenge/Birds of Prey Wallpaper is the link for voting - generally open for one week only.

 

BUT be warned! There are about 950 entries, some of which are not very visible in the low quality rendered wallpaper mockups (those actual designs I checked are of much higher quality).

 

If you do feel reckless and decide for the "new and exciting" voting experience please let me have some quotable quotes re what worked and what didn't so I can pass them on to Spoonflower. Thank you! :-)

 

But I understand if that's too much.

European Green Woodpecker / picus viridis. Lincolnshire. 11/08/16.

 

Apparently, when young Green Woodpeckers fledge, the parent birds stop bonding with each other.

From then on they work independently, taking sole responsibility for half of the young they've reared. They accompany them to feeding sites, feed them until they are self sufficient, teach them life skills by example and generally look out for them. The youngsters for their part remain faithful to the parent in charge, following them closely and imitating their behaviours.

 

This juvenile was overseen by the male bird .....wherever 'Dad' went, s/he was sure to follow. Judging by the state of the beak it was quite capable of probing for food but, like all youngsters, preferred to try it on. There was a great show of begging behaviours accompanied by strangulated, wheezy calls. The male seemed oblivious and spent most time filling himself up!

Whilst photographing the solitary Southern Black-Backed Gull a few days ago that was sitting on the side of the Hutt River, dozens upon dozens of Black-Backed Gulls swooped over-head and landed a little up-river from the loan bird.

 

It wasn't difficult to find them. They numbered in their hundreds and were sitting on a rock bank in the middle of the river! And this was obviously a very big catch-up session - one which even included Juveniles...!

 

After watching them from a discreet distance for about 10 minutes, one of the birds suddenly sounded an alarm (though I didn't hear anything unusual!), and the whole flock swarmed into the air, screaming in panic..! They circled once, and then all swooped back to exactly where they'd been a few seconds earlier, and carried on their respective conversations!

 

What interesting behaviour...!

 

(You'll have to view this in "Extra Large" format (Double-click the photo) to see this big flock in better detail).

  

Continue to keep well everyone, and a big "Thank You" for taking the time and the trouble to leave a Comment...! It's always nice to hear from you, and your comments are always greatly appreciated...!

Used the flip down screen for these shots, a little awkward to say the least but using the spirit level and centre spot focus I managed to bag a few shots.

en.wikipedia.org/wiki/Eurasian_wryneck

  

The Eurasian wryneck (Jynx torquilla) is a species of wryneck in the woodpecker family. This species mainly breeds in temperate regions of Europe and Asia. Most populations are migratory, wintering in tropical Africa and in southern Asia from Iran to the Indian Subcontinent, but some are resident in northwestern Africa. It is a bird of open countryside, woodland and orchards.

 

Eurasian wrynecks measure about 16.5 cm (6.5 in) in length and have bills shorter and less dagger-like than those of other woodpeckers. Their upperparts are barred and mottled in shades of pale brown with rufous and blackish bars and wider black streaks. Their underparts are cream speckled and spotted with brown. Their chief prey is ants and other insects, which they find in decaying wood or on the ground. The eggs are white as is the case with many birds that nest in holes and a clutch of seven to ten eggs is laid during May and June.

 

These birds get their English name from their ability to turn their heads through almost 180 degrees. When disturbed at the nest, they use this snake-like head twisting and hissing as a threat display. This odd behaviour led to their use in witchcraft, hence to put a "jinx" on someone.

  

Taxonomy and etymology

  

The Eurasian wryneck was first described by Carl Linnaeus in the tenth edition of his Systema Naturae in 1758. The type species came from Sweden.[2]

 

The genus name Jynx is from the Ancient Greek name for this bird, iunx. The specific torquilla is Medieval Latin derived from torquere, to twist, referring to the strange snake-head movements.[3] The bird was used as a charm to bring back an errant lover, the bird being tied to a piece of string and whirled around.[3] The English "wryneck" refers to the same twisting movement and was first recorded in 1585.[4]

 

The family Picidae has four subfamilies, the Picinae (woodpeckers), the Picumninae (piculets), the Jynginae (wrynecks) and the monotypic Nesoctitinae (Antillean piculet).[5] Based on morphology and behaviour, the Picumninae was considered to be the sister clade of the Picinae. This has now been confirmed by phylogenetic analysis and the Jynginae are placed basal to the Picinae, Nesoctitinae and Picumninae.[5]

 

Jynginae includes one genus (Jynx) and two species, the Eurasian wryneck and the red-throated wryneck (Jynx ruficollis), resident in sub-Saharan Africa.[6] There are six subspecies of Jynx torquilla: [7]

 

Jynx torquilla chinensis Hesse, 1911

Jynx torquilla himalayana Vaurie, 1959

Jynx torquilla mauretanica Rothschild, 1909

Jynx torquilla sarudnyi Loudon, 1912

Jynx torquilla torquilla Linnaeus, 1758

Jynx torquilla tschusii O. Kleinschmidt,1907

  

Description

  

The Eurasian wryneck grows to about 17 cm (6.7 in) in length.[2] The subspecies Jynx torquilla tschusii weighs 26 to 50 g (0.92 to 1.76 oz).[8] It is a slim, elongated-looking bird with a body shape more like a thrush than a woodpecker. The upperparts are barred and mottled in shades of pale brown with rufous and blackish bars and wider black streaks. The rump and upper tail coverts are grey with speckles and irregular bands of brown. The rounded tail is grey, speckled with brown, with faint bands of greyish-brown and a few more clearly defined bands of brownish-black. The cheeks and throat are buff barred with brown. The underparts are creamy white with brown markings shaped like arrow-heads which are reduced to spots on the lower breast and belly. The flanks are buff with similar markings and the under-tail coverts are buff with narrow brown bars. The primaries and secondaries are brown with rufous-buff markings. The beak is brown, long and slender with a broad base and sharp tip. The irises are hazel and the slender legs and feet are pale brown. The first and second toes are shorter than the others. The first and fourth toes point backwards and the second and third point forwards, a good arrangement for clinging to vertical surfaces.[2]

 

The call of the Eurasian wryneck is a series of repeated harsh, shrill notes quee-quee-quee-quee lasting for several seconds and is reminiscent of the voice of the lesser spotted woodpecker. Its alarm call is a short series of staccato "tuck"s and when disturbed on the nest it hisses.[

  

Distribution and habitat

  

The Eurasian wryneck has a palearctic distribution. The breeding range of the nominate subspecies includes all of Europe from Britain to the Urals. In the north it reaches the Arctic Circle and the range includes Spain in the southwest. In the south and east it intergrades with J. t. tschusii (smaller and more reddish brown) which is found in Corsica, Italy, Dalmatia and parts of the Balkans. J. t. mauretanica (also smaller than the nominate form, light, with whitish throat and breast) is resident in Algeria and Morocco and possibly also the Balearic Islands, Sardinia and parts of Sicily. J. t. sarudnyi (considerably paler than the nominate with fainter markings) occurs in the Urals and then in a wide strip of Asia through southern Siberia, Central Asia, including the north-western Himalayas to the Pacific coast. J. t. chinensis breeds in eastern Siberia and northeastern and central China while J. t. himalayana breeds in Pakistan and the northwestern Himalayas.[9] Eurasian wrynecks also inhabit the island of Sakhalin,[10] Japan and the coastal areas of southern China.[11][12]

 

The Eurasian wryneck is the only European woodpecker to undertake long distance migrations. The wintering area of European species is located south of the Sahara, in a wide strip across Africa extending from Senegal, Gambia and Sierra Leone in the west to Ethiopia in the east. Its southern limit extends to the Democratic Republic of Congo and Cameroon. The populations from West Asia use the same wintering areas. The Central and East Asian breeding birds winter in the Indian subcontinent or southern East Asia including southern Japan.[2]

 

During the summer the bird is found in open countryside, parkland, gardens, orchards, heaths and hedgerows, especially where there are some old trees. It may also inhabit deciduous woodland and in Scandinavia it also occurs in coniferous forests.

  

Behaviour

  

The Eurasian wryneck sometimes forms small groups during migration and in its winter quarters but in the summer is usually found in pairs. It characteristically holds its head high with its beak pointing slightly upwards. A mutual display that occurs at any time of year involves two birds perched facing each other with their heads far back and beaks wide open, bobbing their heads up and down. Sometimes the head is allowed to slump sideways and hang limply. On other occasions, when excited, the head is shaken and twisted about violently. When disturbed on the nest or held in the hand, the neck contorts and twists in all directions. The bird sometimes feigns death and hangs limply with eyes closed.[2]

  

On returning to the breeding area after migration, the birds set up territories. On farmland in Switzerland it has been found that old pear orchards with large numbers of ant nests are preferentially selected over other habitats. Areas used for vegetable cultivation provided useful habitat when they include areas of bare ground on which the birds can forage.[13] Territories are not chosen at random as arriving birds favoured certain areas over others with the same territories being colonised first year after year. The presence of other Eurasian wrynecks in the vicinity is also a positive influence. Orchards in general, and older ones in particular, provide favoured territories, probably because the dense foliage is more likely to support high numbers of aphids and the ground beneath has scant vegetation cover, both of which factors increase the availability of ants, the birds' main prey. Despite some territories being consistently chosen over others, reproductive success in these territories was no higher than in others.[14] Limiting factors for such crevice-nesting species as Eurasian wrynecks are both the availability of nesting sites and the number of ants and their ease of discovery. Modern farming practices such as the removal of hedges, forest patches and isolated trees and the increasing use of fertilisers and pesticides are disadvantageous to such birds.[15]

 

The diet of the Eurasian wryneck consists chiefly of ants but beetles and their larvae, moths, spiders and woodlice are also eaten. Although much time is spent in the upper branches of trees, the bird sometimes perches in low bushes and mostly forages on the ground, moving around with short hops with its tail held in a raised position. It can cling to tree trunks, often moving obliquely, and sometimes pressing its tail against the surface as a prop. It does not make holes in bark with its beak but picks up prey with a rapid extension and retraction of its tongue and it sometimes catches insects while on the wing. Its flight is rather slow and undulating.

  

Breeding

  

The nesting site is variable and may be in a pre-existing hole in a tree trunk, a crevice in a wall, a hole in a bank, a sand martin's burrow or a nesting box.[2] In its search for a safe, protected site out of reach of predators, it sometimes evicts a previous occupant, its eggs and nestlings.[16] It uses no nesting material and a clutch of normally seven to ten eggs is laid (occasionally five, six, eleven or twelve). The eggs average 20.8 by 15.4 millimetres (0.82 in × 0.61 in) and weigh about 0.2 g (0.007 oz). They are a dull white colour and partially opaque. Both sexes are involved in incubation which takes twelve days, but the female plays the greater part. Both parents feed the chicks for about twenty days before they fledge. There is usually a single brood.

  

Status

  

The IUCN lists the Eurasian wryneck as being of "Least Concern" in its Red List of Threatened Species. This is because it has a world population estimated at up to fifteen million individual birds and a very wide geographical range. The population may be decreasing to a certain extent but not at such a rate as to make the bird reach the threshold for a more threatened category.[1] In continental Europe, the largest populations are in Spain, Italy, Germany, Poland, Romania, Hungary, Belarus and Ukraine, and only in Romania is the population trend believed to be upward. In Russia, where there are believed to be 300,000 to 800,000 individuals, the population trend is unknown.[17] In the United Kingdom the numbers of bird are on the decrease and it is protected under Schedule 1 of the Wildlife and Countryside Act 1981 and is listed on Appendix II of the Bern Convention. It is protected as a migratory species under the Birds Directive in the European Union.[18] In Switzerland, the population has also been decreasing, but the species has reacted positively to conservation measures such as the addition of nestboxes in suitable habitats.

Fab little birds

This black heron has adapted to a very unique feeding behaviour making use of its wings to form a canopy, its flight feathers are particularly broad and shaped to help form the closed canopy. The erected nape plumes also help complete the canopy. Its distinctively coloured feet are similar to other herons/egrets, but interestingly, unlike many other species, the black heron’s legs do not change colour in the breeding season, suggesting that dark legs are important in the functioning of the canopy behaviour. The ability of the species to adequately catch fish in shallow open water using its unique shadow-casting behaviour is just short of amazing.

 

Although it’s not perfectly clear why the black heron uses this specific technique, scientists hypothesize that it has several advantages, like reducing glare and attracting the fish into a trap with the fish falsely believing its a safe place to hide in the shade. And because the shade gives the bird a better view of its victim, it can easily snatch it out of the water with its long beak. The black heron is definitely one of the sneakiest predators in the animal realm.

 

Watching with amazement and wondering how he or she can do the same is the glossy ibis.

This lagoon was always a hive of activity while we were at this camp, so many species of birds at all times to entertain between safari outings.

Ugolini BS - Corso Introduzione Alpinismo 2010 - Comportamento su ghiacciaio

I was met with in an accident and leg was fractured. A plate was fixed in my leg. With this, I went to Sankagiri Fort, near Salem, Tamil Nadu, India with my friend and I was not able to walk for long distance and due to pain, I laid down on the way under a tree. Then, around 10 monkeys came near the tree and I was waiting for a good shot with my camera. Suddenly, a monkey took newspaper and while laying down, I shot this photo which I feel is the gift given by God.

I also thank my friend at this moment who was with me at that time. Date :- 11-03-2018 - Timing - 15:17 pm

One of the major reasons why we need to work towards protecting the environment is because it helps to protect humanity. If we didn’t have our environment, then we wouldn’t have a place to live or resources to live.it is our moral obligation to do so. As a human who lives on earth, it is our responsibility to make sure that it is protected. We must give back to the future generation that what we have received and enjoying. Give them an environment that isn’t damaged and teach them how to continue living sustainably. I request all good souls to plant Banyan tree while making tree plantation. It will have a long lasting effect for mankind and go a long way in carry forwarding the nature to the next generation and will also give fruits useful for birds. Instagram Id : @nagendran_c4777. Planting of trees in a special occasion such as Birthday Wedding etc is a excellent gesture. It can be done in memory of our Parents, Teachers, Friends and also people who comes across in our life such as Doctors Nurses and health staff for their noble service to the society.
