@ How to explain the Black Heron's hunting behaviour? @
The bird is mostly seen wading forward rather quickly in an upright position, stopping abruptly and, at the same time, stretching its wings forward over its head to form a canopy, a few centimetres above or sometimes touching the water surface. During this posture, which is only held for two or three seconds, foot-stirring under the canopy can clearly be seen in the majority of occasions. After folding back its wings, the egret again wades with agile steps before resuming the canopy posture.
The canopy-formation may eliminate reflections from the water surface, enabling the egret to see more easily into the water. But is this the sole advantage?

Conversing with Keas:2
Kea have been studying humans from many angles for more than four centuries yet many questions remain unanswered. Most individuals are approachable with care but it is important to remember they are not pets or a tame species and are capable of unpredicably destructive behaviour.
Breeding behaviour
Where possible, the birds excavate a nesting burrow into the soil. Sometimes they will make use of Manx shearwater or rabbit burrows. Where burrowing is not possible, the birds nest under boulders or in cracks and cavities in cliffs.
The birds defend the nesting site and its immediate surround, and use it in subsequent years. Puffins lay only a single egg, in late April or early May. Both parents incubate it for 36-45 days, and they share the feeding duties until the chick is ready to fledge.
The fledging period is very variable, ranging from 34 to 60 days, depending on the area and year.
Adult birds desert their young shortly before they are ready to leave the nest. The timing of the breeding in puffin colonies is highly synchronised, and so the departure of all adults takes place within a few days.
The young birds leave their nest burrow and make their way to the sea, normally under cover of darkness to avoid predators. In some colonies, for instance in Iceland, nearby bright lights confuse the young birds, which then fly into the light and end up on city streets.
Puffins usually reach breeding age at 5-6 years old, and often live for 20 years.

I think there is problem with the site being so polluted.
This project explored the issues, context and behavioural patterns and choices associated with eating and physical activity in adolescents. The evaluation of this project provided NHS Somerset with evidence to support future work with young people around the subject of healthy living.
Artists Richard Tomlinson and Emma Thomson engaged young people (aged 13 – 15) from two Somerset schools through the use of film, photography and drama in an exploration of their and their peer group’s sense of self and identity. They produced a series of photographic and film-based artworks which they peer reviewed. They also contributed towards the development of an online interactive tool that Community Health International will be able to use in future work with young people.
The regular Sunday Evening service at Hexham Community Church results in the complete blocking of the pavement. The large trailer which belongs to a charity is so close to the junction that pedestrians have to walk unseen into the main road.
This Air Jamaica plane was about 30 degrees off course. It made a dramatic dip and turn and bank - I swear, those passengers had to be frightened as hell. I was... since it headed right at me after turning! Act of terrorism and I have my camera, lovely... er, not.
Governments around the world are drawing on behavioural insights to improve public policy outcomes: from automatic enrolment for pensions, to better tax compliance, to increasing the supply of organ donation.
But those very same policy makers are also subject to biases that can distort decision making. The Behavioural Insights Team has been studying those biases and what can be done to counter them, in collaboration with Jill Rutter and Julian McCrae of the Institute for Government.
The report was launched with remarks from Alex Chisholm, Permanent Secretary at the Department for Business, Energy, and Industrial Strategy.
Dr Michael Hallsworth, Director of the Behavioural Insights Team in North America presented the key findings.
The findings, their relevance to policy making today, and what they mean for the way governments make decisions were discussed by:
Polly Mackenzie, Director of Policy for the Deputy Prime Minister, 2010–15 and now Director of Demos
Dr Tony Curzon Price, Economic Advisor to the Secretary of State for Business, Energy and Industrial Strategy.
The event was chaired by Jill Rutter, Programme Director at the Institute for Government.

Based on the white tips on the tail, the small erectile crest and the general colouring, I think this is an immature Eastern Whipbird. It is extracting insects from rolled up, fallen bark at the top of the Golden Stairs on Narrow Neck.
The Eastern Whipbird (Psophodes olivaceus) is an insectivorous passerine bird native to the east coast of Australia, its whip-crack call a familiar sound in forests of eastern Australia. Two subspecies are recognised. Heard much more often than seen, it is a dark olive-green and black in colour with a distinctive white cheek patch and crest. The male and female are similar in plumage. Juveniles are a duller olive-brown and lack the white cheek stripes and dark throat. en.wikipedia.org/wiki/Eastern_Whipbird

This looks like mating behaviour. And perhaps it is. The female had just delivered some grasses into their nesting box. The male perched nearby with a bug in his beak. When the female emerged he flew over to her and, from the back, deposited the bug into her mouth. Here, he is flying away after feeding her.

Baboons are terrestrial monkeys and among the most entertaining of African animals to watch, perhaps because they exhibit many behaviours rather similar to our own. Troops typically number between 20 and 80 individuals, although bigger aggregation of over 100 members are known. A troop consist of several kinship groups of adult females and their offspring, as well as a number of mature, sexually-active males. There is a strict hierarchy among the females and the males, with individual males generally having exclusive mating rights to certain kinship groups. Immature males are tolerated within the troop until they reach five years of age, after which they attempt to join neighbouring troops. Individual male baboons are formidable animals armed with large canine teeth, and fear only lions and large male leopards. When two or more male baboons are together, even these predators usually give them a wide berth. This partial immunity from predation has allowed baboons to develop a terrestrial lifestyle, although constant vigilance is required to keep the young out of danger. Baboons frequently forage alongside antelope as the acute hearing of these herbivores provides an early warning against predators. At night, baboons gather to roost in large trees along watercourses or on steep rock faces. Like other primates, baboons are omnivorous. The troop forages in a loose group, digging up succulent roots, turning over rocks in search of insects and scorpions, gorging themselves on fruit and berries, or wading into shallow pools for water lily tubers. The newborn fawns of gazelle and antelope may be preyed upon by adult male baboons. Baboons can become a pest in agricultural areas as they raid orchards and feed on crops, so they are often heavily persecuted by farmers. They can even become a menace around safari lodges, where baboon chasers are sometimes employed to discourage them. The number of baboon species is disputed, with some authors lumping the Guinea, chacma, olive and yellow baboons as a single species - the savanna baboon.
