Many women still die in pregnancy and childbirth and many children do not survive their first year.
UCL Global Health has helped to form women's groups in Bangladesh, India, Malawi and Nepal.
The groups mobilised their communities to change the behaviours that affected maternal and infant health. They recorded a 37% reduction in maternal mortality.
While in Ohio at the Midwest Birding Symposium we saw ring-billed gulls landing in dog wood trees and eating the berries.
Gulls are scavengers but I didn't know they would eat fruit.
It may be possible they were eating insects and not the berries but that isn't what it looked like.
Scientific stuff
Larus delawarensis
From Cornell Lab of OrnithologyFamiliar acrobats of the air, Ring-billed Gulls nimbly pluck tossed tidbits from on high. Comfortable around humans, they frequent parking lots, garbage dumps, beaches, and fields, sometimes by the hundreds. These are the gulls you're most likely to see far away from coastal areas—in fact, most Ring-billed Gulls nest in the interior of the continent, near freshwater. A black band encircling the yellow bill helps distinguish adults from other gulls—but look closely, as some other species have black or red spots on the bill
Many, if not most, Ring-billed Gulls return to breed at the colony where they hatched. Once they have bred, they are likely to return to the same breeding spot each year, often nesting within a few meters of the last year's nest site. Many individuals return to the same wintering sites each winter too.

Thank you to the vast majority of fans last night for your excellent behaviour while watching the England game.
Although the score didn’t go our way, fans by-and-large were brilliant and watched the #WorldCup semi-final between England and Croatia in good spirits.
Nine arrests were made in total in Manchester City Centre including public order offences and being drunk and disorderly, but thankfully no serious incidents took place.
We would also like to thank all the officers who worked hard to keep everyone safe last night, with many having to give up their plans of watching the game with friends and family.
Yesterday was a testament to fans – you came together, helped look after each other and dealt with the result graciously.
Bring on Euro 2020!

Scrutiny and harassment by a group of crows on Parksville Bay, Vancouver Island. We had a peaceful walk in late morning along with a few paired residents and many varieties of birds. The structure was erected by an anonymous person on an island in the bay that comes and goes at the whim of the tide, currents, and wind.
Usually as in this case the Black Headed Gulls plunge in and grab a piece of vegitation or if there lucks in perhaps a small fish such as a Stickleback either way any gulls in the vicinity will begin the chase to try and steal it's prize.

When some children are randomly selected and their teacher is told they are likely to bloom intellectually over the next few months, they do.
This is the self-fulfilling fulfilling prophecy.
(It happens probably because the teacher expects the child to learn faster so gives it more challenging tasks)

A stereotypy is a repetitive or ritualistic movement, posture, or utterance, found in patients with mental retardation, autism spectrum disorders, tardive dyskinesia, frontotemporal dementia and stereotypic movement disorder. Stereotypies may be simple movements such as body rocking, or complex, such as self-caressing, crossing and uncrossing of legs, and marching in place. Several causes have been hypothesized for stereotypy, and several treatment options are available.
Stereotypy is sometimes called stimming in autism, under the hypothesis that it self-stimulates one or more senses. Related terms include punding and tweaking to describe repetitive behavior that is a side effect of some drugs.
Mute Swan - Courtship and Copulatory Behaviour
The Mute Swan (Cygnus olor) is a species of swan native to much of Europe and Asia.This large swan is wholly white in plumage with an orange bill bordered with black. The name 'mute' derives from it being less vocal than other swan species. The population in the UK has increased recently, perhaps due to better protection of this species. Around 5,800-7,000 pairs breeding annually in UK.
Mayesbrook Park (Barking), Britain’s first climate change park, is an attractive nature reserve with a newly restored river landscape. The Mayes brook has been brought back into the park within a widened meandering river channel creating an attractive river landscape to help the park to cope with more extreme changes in climate including heavy rainfall and drought. This new river system, with a gravel river bed and banks, provides an ideal wetland habitat for wildlife and at times of high rainfall it is able to rise in a controlled and natural way within a newly created floodplain.
The southern section of the park features two large lakes which are rich in wildlife. Aquatic plants such as reeds and rushes have been planted in ponds and backwaters, creating a rich habitat for wetland species. With over 40 hectares of open space, the park recently received a Mayor of London Safer Parks Silver award for high standards of site safety and policing.

The Red-throated Diver (Gavia stellata), known in North America as the Red-throated Loon, is a migratory aquatic bird that is found in the temperate regions of the northern hemisphere. It is the smallest and most widely distributed member of the loon or diver family.
Around 55–67 centimetres (22–26 in) in length, the Red-throated Diver is a nondescript bird in winter, greyish above fading to white below. During the breeding season, it acquires the distinctive reddish throat which gives rise to its common name. Fish form the bulk of the diet, with invertebrates and plants sometimes eaten as well. A monogamous species, the Red-throated Diver forms long-term pair bonds.

[edit] Taxonomy and etymology
First described by Danish naturalist Erik Pontoppidan in 1763, the Red-throated Diver is a monotypic species, with no distinctive subspecies despite its large Holarctic range.[2] Pontoppidan initially placed the species in the now-defunct genus Colymbus, which contained grebes as well as divers. By 1788, however, German naturalist Johann Reinhold Forster realized that grebes and divers were different enough to warrant separate genera, and moved the Red-throated Diver (along with all other diver species) to its present genus.[3] Its relationship to the four other divers is complex; though all belong to the same genus, it differs more than any of the others in terms of morphology, behaviour, ecology and breeding biology. It is thought to have evolved in the Palearctic, and then to have expanded into the Nearctic.[2]
The genus name Gavia comes from the Latin for "sea mew", as used by ancient Roman naturalist Pliny the Elder.[4] The specific epithet stellata is Latin for "set with stars" or "starry",[5] and refers to the bird's speckled back in its non-breeding plumage.[4] "Diver" refers to the family's underwater method of hunting for prey, while "red-throated" is a straightforward reference to the bird's most distinctive breeding plumage feature. The word "loon" is thought to have derived from the Swedish lom, the Old Norse or Icelandic lómr, or the Old Dutch loen, all of which mean "lame" or "clumsy", and is a probable reference to the difficulty that all divers have in moving about on land.[6]
[edit] Description
The Red-throated Diver is the smallest and lightest of the world's diver species, ranging from 55–67 centimetres (22–26 in) in length with a 91–110 centimetres (36–43 in) wingspan,[7] and averaging 1.4 kilograms (3.1 lb) in weight.[8] Like all divers, it is long-bodied and short-necked, with its legs set far back on its body.[9] The sexes are similar, although males tend to be slightly larger and heavier than females.[2] In breeding plumage, the adult has a grey head and neck (with narrow black and white stripes on the back of the neck), a triangular red throat patch, white underparts and a dark mantle. It is the only diver with an all-dark back in breeding plumage. The non-breeding plumage is drabber with the chin, foreneck and much of the face white, and considerable white speckling on the dark mantle. Its bill is thin, straight and sharp, and the bird often holds it at an uptilted angle. Though the colour of the bill changes from black in summer to pale grey in winter, the timing of the colour change does not necessarily correspond to that of the bird's overall plumage change. The nostrils are narrow slits located near the base of the bill, and the iris is reddish.
An adult in non-breeding plumage shows the speckled back which gives the bird its specific name.When it first emerges from its egg, the young Red-throated Diver is covered with fine soft down feathers. Primarily dark brown to dark grey above, it is slightly paler on the sides of its head and neck, as well as on its throat, chest, and flanks, with a pale grey lower breast and belly. Within weeks, this first down is replaced by a second, paler set of down feathers, which are in turn replaced by developing juvenile feathers.[10]
In flight, the Red-throated Diver has a distinctive profile; its small feet do not project far past the end of its body, its head and neck droop below the horizontal (giving the flying bird a distinctly hunchbacked shape) and its thin wings are angled back. It has a quicker, deeper wingbeat than do other divers.[8]
[edit] Voice
The adult Red-throated Diver has a number of vocalisations, which are used in different circumstances. In flight, when passing conspecifics or circling its own pond, it gives a series of rapid yet rhythmic goose-like cackles, at roughly five calls per second. Its warning call, if disturbed by humans or onshore predators, is a short croaking bark. A low-pitched moaning call, used primarily as a contact call between mates and between parents and young, but also during copulation, is made with the bill closed. The species also has a short wailing call, which descends slightly in pitch and lasts about a second; due to strong harmonics surrounding the primary pitch, this meowing call is more musical than its other calls. Another call—a harsh, pulsed cooing that rises and falls in pitch, and is typically repeated up to 10 times in a row—is used in territorial encounters and pair-bonding, and by parent birds encouraging their young to move on land between bodies of water.[11] Known as the "long call", it is often given in duet, which is unusual among the divers;[12] the female's contribution is longer and softer than her mate's.[11]
Young have a shrill closed-bill call, which they use in begging and to contact their parents. They also have a long call used in response to (and similar to that of) the long call of adults.[11]
[edit] Habitat and distribution
The Red-throated Diver breeds primarily in the Arctic regions of northern Eurasia and North America (generally north of 50°N latitude), and winters in northern coastal waters.[13] Unlike other divers, the Red-throated Diver regularly uses very small freshwater lakes as breeding sites.
In North America, it winters regularly along both coasts, ranging as far south as the Baja California Peninsula and the Gulf of California in northwestern Mexico; it has been recorded as a vagrant in the interior Mexican state of Hidalgo.[14] In Europe, it breeds in Iceland, northern Scotland, Scandinavia and northern Russia, and winters along the coast as far south as parts of Spain; it also regularly occurs along major inland waterways, including the Mediterranean, Aegean and Black Seas, as well as large river, lakes and reservoirs.[15] It has occurred as a vagrant as far south as Morocco, Tunisia and The Gambia.[1]
Some of its folknames in northeastern North America—including cape race, cape brace, cape drake and cape racer, as well as corruptions such as scapegrace—originated from its abundance around Cape Race, Newfoundland.[16]
[edit] Behaviour
Because its feet are located so far back on its body, the Red-throated Diver is not capable of walking on land; however, it can use its feet to shove itself forward on its breast.[8] Young use this method of covering ground when moving from their breeding pools to larger bodies of water, including rivers and the sea.[17] It is the only species of diver able to take off directly from land.[18]
The Red-throated Diver is a diurnal migrant, which travels singly or in loose groups, often high above the water.[8] In eastern North America (and possibly elsewhere), it tends to migrate near the coast rather than farther offshore.[19] It is a strong flier, and has been clocked at speeds between 75 and 78 kilometres per hour (47–49 mph).[20] Like all members of its family, the Red-throated Diver goes through a simultaneous wing moult, losing all its flight feathers at once and becoming flightless for a period of 3–4 weeks. However, unlike other divers—which undergo this moult in late winter—the Red-throated Diver loses its ability to fly sometime between early August and November.[21]
[edit] Food and feeding
Like all members of its family, the Red-throated Diver is primarily a fish-eater, though it sometimes feeds on molluscs, crustaceans, frogs, aquatic invertebrates, insects, fish spawn or even plant material.[22] It seizes rather than spears its prey, which is generally captured underwater.[23] Though it normally dives and swims using only its feet for propulsion, it may use its wings as well if it needs to turn or accelerate quickly.[24] Pursuit dives range from 2–9 metres (6.6–30 ft) in depth, with an average underwater time of about a minute.[22] The fish diet of the Red-throated Diver has led to several of its folknames, including "sprat borer" and "spratoon".[25]
Chicks are competent swimmers, able to accompany their parents soon after hatching.For the first few days after hatching, young Red-throated Divers are fed aquatic insects and small crustaceans by both parents. After 3–4 days, the parents switch to fish small enough for the young birds to swallow whole. By four weeks of age, the young can eat the same food—of the same size—as their parents do.[26] Young birds may be fed for some time after fledging; adults have been seen feeding fish to juveniles at sea and on inland lakes in the United Kingdom, hundreds of kilometers from any breeding areas.[27][28]
[edit] Breeding
The Red-throated Diver is a monogamous species which forms long-term pair bonds. Both sexes build the nest, which is a shallow scrape (or occasionally a platform of mud and vegetation) lined with vegetation and sometimes a few feathers, and placed within a half-metre (18 in) of the edge of a small pond. The female lays two eggs (though clutches of 1–3 have been recorded); they are incubated for 24–29 days, primarily by the female. The eggs, which are greenish or olive-brownish spotted with black, measure 75 x 46 millimetres (3.0 x 1.8 in) and have a mass of 83 grams (2.9 oz), of which 8 percent is shell.[23][29] Incubation is begun as soon as the first egg is laid, so they hatch asynchronously. The young birds are precocial upon hatching: downy and mobile with open eyes; both parents feed them (small aquatic invertebrates initially, then small fish) for 38–48 days. Parents will perform distraction displays to lure predators away from the nest and young.[23] Ornithologists disagree as to whether adults carry young on their backs while swimming with some maintaining that they do[23] and others the opposite.[30]
[edit] Conservation status and threats
JuvenileThough the Red-throated Diver is not a globally threatened species, as it has a large population and a significant range, there are populations which appear to be declining. Numbers counted in U.S. Fish and Wildlife Service surveys in Alaska show a 53 percent population decline between 1971 and 1993, for example,[31] and counts have dropped in continental Europe as well.[32] In Scotland, on the other hand, the population increased by some 16 percent between 1994 and 2006, according to surveys done by the Royal Society for the Protection of Birds and Scottish Natural Heritage.[32] In 2002, Wetlands International estimated a global population of 490,000 to 1,500,000 individuals; global population trends haven't been quantified.[1]
The Red-throated Diver is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies;[33] in the Americas, it is protected by the Migratory Bird Treaty Act of 1918.[34] Oil spills, habitat degradation, and fishing nets are among the main threats this species faces.[30] In addition, high levels of mercury in the environment have led to reproductive failures in some areas, including parts of Sweden.[35] On the breeding grounds, Arctic and Red Foxes are major predators of eggs,[36] while Great Skuas, Arctic Skuas and various species of Larus gulls (including Great Black-backed Gulls and Glaucous Gulls)[37][38] are predators of both eggs and young.[39]
[edit] In human culture
Used as a food source since prehistoric times,[40][41] the Red-throated Diver is still hunted by indigenous peoples in some parts of the world today.[42] Eggs as well as birds are taken, sometimes in significant numbers; during one study on northern Canada's Igloolik Island, 73% of all Red-throated Diver eggs laid within the 10 km2 (3.9 mi2) study site over two breeding seasons were collected by indigenous inhabitants of the island.[43] In some parts of Russia, Red-throated Diver skins were traditionally used to make caps, collars and other clothing trim.[44] The species was also central to the creation mythologies of indigenous groups throughout the Holarctic.[45] According to the myth—which varies only slightly between versions, despite the sometimes-vast distances that separated the groups who believed it—the diver was asked by a great shaman to bring up earth from the bottom of the sea. That earth was then used to build the world's dry land.[45][46]
As recently as the 1800s, the Red-throated Diver was thought to be a foreteller of storms; according to the conventional wisdom of the time, birds flying inland or giving short cries predicted good weather, while those flying out to sea or giving long, wailing cries predicted rain.[29][32] In the Orkney and Shetland islands of Scotland, the species is still known as the "rain goose" in deference to its supposed weather-predicting capabilities.[32]
Bhutan, Japan and the Union of the Comoros have issued stamps featuring the Red-throated Diver.[47]

The sight of a mobile speed camera van is sure to calm the traffic.
All of a sudden seat belts are fastened, speeds are reduced to below the limit, care and attention is paid, semi clothed Nymphs riding Unicorns roam freely scattering magic dust behind them...
To those who claim that these forms of enforcement are somehow unfair or a 'money maker'... when you start a vehicle you are agreeing to terms and conditions. Those terms and conditions are the rules of the road - including parking, speed limits, alcohol limits, duty of care for others and much more.
If you break the rules, then expect a sanction. Simple really.

Ebony Jewelwing (Calopteryx maculata) female and male behaviour (teaser).

Please view full screen for best quality. ;-)
I'm editing several interesting clips together, but wanted to share this one short clip right away. ;-)
Ebony Jewelwings have very sophisticated courtship and ovipositing rituals. Females line the stream banks to watch males "joust" for their attention. FEMALES pick their partner based on these competitions. That's rare in the dragon-damselfly world. Typically, the male literally grabs a female by the scruff of her neck and hope she cooperates! @@
The reason these jousting sessions are so important to the females is because the males "hover guard" the female they mated with, to ensure that HIS progeny's eggs are safely laid in the stream (they lay their eggs on partially submerged logs, twigs or leaves.) She depends on the male's ability to stand guard while she lays her eggs.
Ebony Jewelwings (Calopteryx maculata) prefer relatively clear, fast-moving streams. The male sentry butts heads and chases away any other male that tries to interfere while she's laying her (HIS) eggs underwater (their nymphs are aquatic). I got video of that behaviour too, but I'll save that for later.
This sneak preview is something I've never seen before. A rival male managed to slip past the hover-guarding male and tossed the egg-laying female right off her log!!
I always thought the competing male would just want to mate, but he seems to be more interested in interrupting the egg-laying process.
These beautiful and fascinating creatures never cease to amaze! ❤

Why everybody must be blonde?
Today all the girls want to be blonde and blue eyed.
Blame it to the stereotypes of Capitalism and its
famous icon of Barbie Girls like that vulgar singer
called Lady Gaga (if you don´t have noticed yet,
all in her is fake, starting from her fake blue eyes,
and ending to her platinum dyed hair). But there
was a time, in the early 30´s , where all the girls
want to have dark hair, like Betty Boop, a cartoon
character created in 1930 during the great depresion.
Betty was the first sex symbol, and was not made of
flesh and blood hahaha. Many years before Marilyn
Monroe and Rita Hayworth she wore short dresses,
high heels, a garter belt, and a generous neckline :P
Someting very revolutionary for the rancind moral of that
age where all the good girls girls must be at home cleaning
their houses, cooking, taking care of their children and pleasing
their men. That´s the reason I´ve always found Betty very funny
(add this that in the first sketches that Max Fleischer draw
Betty looked like a French poodle :D). Forgot to say that Betty
character was inspired by the "Flapper girls", who loved Jazz music,
short haircuts (garçonne style) and have a rebel behaviour
against men and s society :D
THE MEANING OF LIFE
Just a bit of Philosophy, and
sometimes a little bit of irony.
Photographs that sometimes
are chained with others. Play
with them jumping from one
picture to another like If you
were playing hopscotch.
P.S. Dear voyeur (presumed dumb) :P
many thanks for your indiference about my art :P
and dear thief (presumed with more snout
than a tapir :P), Please do not use my photographs,

¿Por qué todo el mundo tiene que ser rubio?
Hoy en día todas las chicas quieren ser rubias y tener los
ojos azules. Echenle la culpa al Capitalismo y a sus famosos
iconos de Chicas Barbies, como la vulgar Lady Gaga (por si
aún no sea han dado cuenta, todo en ella es falso, empezando
por el falso azúl de sus ojos y terminando por su pelo teñido de
rubio platino). Pero hubo un tiempo, en los años treintas, en que
todas las chicas querían tener los cabellos oscuros, como Betty
Boop, un personaje de comic creado en 1930 durante la gran
depresión. Betty fue el primer símbolo sexual y no era de carne
y hueso, jajaja, muchos años antes que Mrilyn Monroe y Rita Hayworth,
ella ya lucía vestido cortos, tacones altos, liguero y un generoso
escote :P Algo muy revolucionario para la rancia moral de aquella
época, que defendía que las chicas buenas tenían que quedarse
en casa, limpiando, cocinando, cuídando de sus hijos, y satisfaciendo
a sus hombres. Esa es la razón por la que siempre he encontrado a
Betty muy divertida (añandanle a eso, que en los primeros bocetos
que dibujo Max Fleischer, ella tenía forma de caniche francés :D).
Olvidé decir que el personaje de Betty estaba inspirado en las
"chicas flapper", que escuchaban música Jazz, llevaban el pelo corto
(a lo garçon, o sea, a lo chico), y tenían un comportamiento rebelde
contra los hombres y la sociedad :D
EL SENTIDO DE LA VIDA.
Soló un poquito de Filosofía
y a veces una pizca de ironía.
Fotos que a veces están escadenadas
entre ellas. Juega saltando de foto en
foto como si jugaras a la Rayuela.
