Common Blue Butterfly:-
Living up to its name, this butterfly is the commonest blue found in the British Isles. While the male has bright blue uppersides, the female is primarily brown, with a highly variable amount of blue. This is the most widespread Lycaenid found in the British Isles and can be found almost anywhere, including Orkney. It is absent, however, from Shetland and the mountainous areas of Wales and Scotland. This butterfly forms reasonably discrete colonies measured in tens or hundreds, with individuals occasionally wandering some distance.

Orange tip - Anthocharis cardamines
Female
The Orange-tip is a true sign of spring, being one of the first species to emerge that has not overwintered as an adult. The male and female of this species are very different in appearance. The more-conspicuous male has orange tips to the forewings, that give this butterfly its name. These orange tips are absent in the female and the female is often mistaken for one of the other whites, especially the Green-veined White or Small White. This butterfly is found throughout England, Wales and Ireland, but is somewhat-local further north and especially in Scotland. In most regions this butterfly does not form discrete colonies and wanders in every direction as it flies along hedgerows and woodland margins looking for a mate, nectar sources or foodplants. More northerly colonies are more compact and also more restricted in their movements.

Flickr EXPLORE History:
Snowy day. I was enjoying the white silence of the forest, the slight squeaking of my steps in the powder snow. A slight movement at the edge of my field of vision made my head spin. They were watching me ....
Luckily I had my camera slung over my shoulder. Just enough time to aim and shoot .... before they disappeared.

The peregrine falcon (Falco peregrinus), also known as the peregrine, and historically as the duck hawk in North America, is a widespread bird of prey (raptor) in the family Falconidae. A large, crow-sized falcon, it has a blue-grey back, barred white underparts, and a black head. The Peregrine is renowned for its speed, reaching over 320 km/h during its characteristic hunting stoop (high-speed dive), making it the fastest bird in the world and the fastest member of the animal kingdom. According to a National Geographic, the highest measured speed of a peregrine falcon is 389 km/h. As is typical of bird-eating raptors, peregrine falcons are sexually dimorphic, with females being considerably larger than males. According to one study, it has the fastest visual processing speed of any animal tested so far, and can register discrete changes up to 129 Hz or cycles per second. As an analogy, film is a series of still images projected onto a screen. Those still images need to be changing at roughly 25 frames per second before humans see them as fluid and no longer as individual, discrete pictures. The film would have to be refreshing at 129 frames per second before peregrine falcons stopped seeing flashing, still images and started seeing fluid motion. 16022
The American robin (Turdus migratorius) is a migratory bird of the true thrush genus and Turdidae, the wider thrush family. It is named after the European robin[2] because of its reddish-orange breast, though the two species are not closely related, with the European robin belonging to the Old World flycatcher family.
The American robin is active mostly during the day and assembles in large flocks at night. Its diet consists of invertebrates (such as beetle grubs, earthworms, and caterpillars), fruits, and berries. It is one of the earliest bird species to lay its eggs, beginning to breed shortly after returning to its summer range from its winter range. The robin's nest consists of long coarse grass, twigs, paper, and feathers, and is smeared with mud and often cushioned with grass or other soft materials. It is among the earliest birds to sing at dawn, and its song consists of several discrete units that are repeated.
More discrete colors but possibly even more elegant than the flamboyant male. At the Loch, Central Park, New York.
The repertoire of vocalisations of the Lion is large; rather than discrete signals, variations in intensity and pitch appear to be central to communication. Most lion vocalisations are variations of growling, snarling, miaowing and roaring. Other sounds produced include purring, puffing, bleating and humming.
Lions tend to roar in a very characteristic manner starting with a few deep, long roars that subside into a series of shorter ones. They most often roar at night; the sound, which can be heard from a distance of 8 kilometres (5.0 mi), is used to advertise the animal's presence

Maybe it's wrong when we remember breakthroughs to our own being as something that occurs in discrete, extraordinary moments. Maybe falling in love, the piercing knowledge that we ourselves will someday die, and the love of snow are in reality not some sudden events; maybe they were always present. Maybe they never completely vanish, either.

Electricity is not digital. It does not come in discrete packets, but floods the air and flows through conductors and shoots from the hands of mad scientists in silent movies. If it is futuristic at all, it is a past version of the future, temperamental, unstable, half-alive.

This is the first time I am raising a female cat and the behaviour is so different from male cats. It's being such a joy to observe the female more discrete and subtle ways.
Akasha has a charming way of placing her irises on top of her eyes when she looks at you. I have seem some female actresses doing that.

The collective noun for mongoose is Business. Here a Business of mongoose were moving along when we approach.
Mongoose are related to the Meerkats. They are omnivores, their diet includes small animals, reptiles, insects - and they even attack snakes.
Their chatter to one another includes discrete units of sound that can sound vaguely human.
Hope you enjoy listening to Paul McCartney and Wings singing " Band On The Run"

When this outfit from CandyDoll was posted on Flickr I knew I had to have it, and it’s as gorgeous as I hoped it would be. Just beware though, it’s advertised as a dress but it’s VERY short (!), so either wear it with some jeans or invest in a discrete pair of panties to wear underneath 😊
Small Heath:-
Despite its name, the Small Heath is not confined to heathland and can be found in a wide variety of habitats. The main distinguishing feature of this species is that this is the smallest of our 'browns' and is closer in size to a skipper, Common Blue or Brown Argus than its relatives, such as the Meadow Brown. However, its fluttering flight is quite different from that of the skippers and blues and is relatively-easy to identify in the field. This charming little butterfly always settles with its wings closed, where the eye spot on the underside of the forewing is usually visible, acting as a decoy to any predator. The forewings are tucked behind the hindwings when roosting for long periods, or in dull weather, the butterfly looking quite inconspicuous as the browns and greys of the underside of the hindwing blend in with their surroundings.
This is a widespread butterfly and can be found over most of the British Isles, with the exception of Orkney and Shetland and mountainous regions. It lives in discrete colonies and adults rarely venture far from the colony. However, the odd adult will venture further afield and will colonise nearby habitat if it is suitable.

In the picture you can see an example of the optical phenomenon known as “ Omega Sun”. The name is due to the apparent shape of the solar disk, similar to that of the Greek letter omega. In reality, what we see is the fusion of two images: the real image of the disk, slightly stretched vertically, and a portion of its mirror image ( and therefore upside down ) that forms the base of the omega. The phenomenon is due to the refraction of light, that is to say the deviation of the rays of light when they pass through layers of different substances having different refractive indices. In the case of the photo, taken at sunrise on a summer day, the sea, warmer than the air above, creates a thin layer of warmer and less dense air that causes the phenomenon.
The observation of the “ Omega Sun “ is not easy because it requires the simultaneous occurrence of three events: absence of clouds on the horizon, transparent air and, finally, a discrete difference of temperature between the sea and the atmosphere.
