Yuki being the big sister (on the left) is trying her best to set Emily straight on the hierarchy of this family of ours. However it seems to go in one ear and out the other with a puppy.
Dominance and hierarchy., otherwise known as the Pecking Order
This young Gannet is getting a lesson in it., and in a few years it'll no doubt be dishing it out lessons of it's own
It's the way of the world and the reason every species in the world has evolved to what it has today

Nile crocodile on the banks of the Talek River.
The Nile crocodile (Crocodylus niloticus) is an African crocodile and the second largest extant reptile in the world, after the saltwater crocodile. The Nile crocodile is quite widespread throughout Sub-Saharan Africa, and lives in different types of aquatic environments such as lakes, rivers and marshlands. The Nile crocodile is between (13 ft) to (16 ft), and weighs around 410 kg (900 lb
The Nile crocodile is an opportunistic apex predator and a very aggressive species of crocodile capable of taking almost any animal within its range. Their diet consists mostly of different species of fish, reptiles, birds and mammals.
The Nile crocodile is an ambush predator and can wait for hours, days and even weeks for a suitable moment to attack. They are quite agile predators and wait for the opportunity for the prey item to come close within the range of attack.
Nile crocodiles are very social crocodiles. They share basking spots and large food sources such as schools of fish and big carcasses. There is a strict hierarchy, that is determined by size. Large, old males are at the top of this hierarchy and have primary access to food and the best basking spots. Crocodiles know their place in the hierarchical order and rarely act against it.
The Nile crocodile is one of the most dangerous species of crocodile and is responsible for hundreds of deaths of humans every year. It is a rather common species of crocodile and is not endangered. – Wikipedia

Every fall, we get to witness the hierarchy of bucks in the area. This guy is second in line. Unlike the younger males that run from the head honcho when he even looks at them, this one is up for the challenge.

The yellow mongoose (Cynictis penicillata), sometimes referred to as the red meerkat, is a small mammal averaging about 1 lb (1/2 kg) in weight and about 20 in (500 mm) in length. A member of the mongoose family, it lives in open country, from semi-desert scrubland to grasslands in Angola, Botswana, South Africa, Namibia, and Zimbabwe.
The yellow mongoose is carnivorous, consuming mostly arthropods but also other small mammals, lizards, snakes and eggs of all kinds.
The yellow mongoose is primarily diurnal, though nocturnal activity has been observed. Living in colonies of up to 20 individuals in a permanent underground burrow complex, the yellow mongoose will often co-exist with Cape Ground Squirrels or suricates and share maintenance of the warren, adding new tunnels and burrows as necessary. The tunnel system has many entrances, nearby which the yellow mongoose makes its latrines.
The social structure of the yellow mongoose is hierarchical, based around a central breeding pair and their most recent offspring. There are also subadults, the elderly, or adult relatives of the central pair. Male ranges tend to overlap, while females from other dens have contiguous non-overlapping ranges. - Wikipedia

The iconic crocodile found in Africa, the Nile crocodile is the second largest crocodile in the world, reaching a typical adult length of 4.5 metres (14.7 feet). The Nile crocodile is quite widespread throughout sub-Saharan Africa, the Nile Basin, and Madagascar in rivers, freshwater marshes, and mangrove swamps.
On average the Nile crocodile is between 4 metres (13.1 feet) to 4.5 metres (14.7 feet), weighing around 410 kg (900 lb). However, specimens measuring 5 metres (16.4 feet) in length and weighing 600 kg (1,300 lb) can occasionally be seen. Nile crocodiles are found along the eastern and southern regions of Africa. The population in the West of the continent are now recognised as a separate crocodile species, the West African Crocodile (Crocodylus suchus). However, specimens measuring 6.1 metres (20 ft) in length and weighing 907 kg (2,000 lb) have been recorded. They have thick scaly skin that is heavily armored.
The Nile crocodile is an opportunistic apex predator and a very aggressive species of crocodile that is capable of taking almost any animal within its range. They are generalists, taking a variety of prey. Their diet consists mostly of different species of fish, reptiles, birds and mammals.

These Great Blue Herons look ready to leave the nest and the hierarchy among the nestlings seems obvious. The dominant heron stands tall, and chatters with two of the others. All three of those herons' crests are elevated, and all three are animated.
The fourth heron sits crouched over, crest flat and in disarray. He is so far to the edge of the nest, that he appears on the verge of falling out.
This hierarchy can occur in many ways. For example, all of the eggs may not have hatched at the same time, and the ones that hatch first will have a head start at being fed and growing. The "sad sack" heron may have suffered an injury, an illness, or just received "bad genes" from its parents.

“Creation becomes a hierarchy of mirrors, each casting an image of God. The farther off the individual image is from God, the smaller the image of Him it reflects, but his brightness never diminishes.”
-James Miller, “Three Mirrors of Dante’s Paradiso,” 266.
What Dante sees in the Primum Mobile is this perspective[11] visually reversed; instead of being the outer “crust” of the universe, the Primum Mobile is actually next to the central Still Point, whirling with inconceivable speed. God, the Still Point, is a non-spatial entity which is everywhere and nowhere.
-Allen Tate, “The Symbolic Imagination,” 271.

The hierarchy of deer feeding. It is so interesting to watch who gets to eat and how some deer try to sneak in for a bite to eat

Golden cups, here a definite ‘pecking’ order, from bud to bloom eh…
I love seeing where they come from, the bud, what they look like at their peak, the bloom, and the in-between, love ALL!
So beautifully layered, all coming out of this one bud, this bud unfurling and displaying all this beauty... it NEVER ceases to amaze me.
The evolution, the unfurling, ready for the GRAND opening...

Excerpt from the plaque:
At RBG Centre's Hierarchy of Nature installation, explore the link between athletes and nature. Athletes seek bronze, silver, and gold; our horticulturists pursue excellence through integrity, strength, and creativity. Both find inspiration in nature's resilience and adaptability, striving to achieve new heights.
The dominance hierarchy is constantly changing. These are the same two Plains Bison males featured in the current series, engaged in a little testing. The bull on the right was the aggressor; he was slightly taller and heavier, and tried to use this to advantage. The slightly smaller bull on the left seemed happy to engage in a little friendly head shoving. It seemed to be more like playing than fighting, but of course the underlying intent was serious: establishing dominance.
The REALLY serious challenges will happen between mid-July and mid-August, when the annual rut unfolds. This happens in a remote, inaccessible area, and whereas I would love the photo ops, it's probably best that tourists are nowhere near, because it can get dangerous. I've seen serious injuries in the aftermath, including a bull bison that had been badly gored. A sad outcome for him, as he died a few days later. But a protein extravaganza for the local coyotes, magpies, ravens, and other scavengers.
Tomorrow: the prairie wildlife series continues with some different species...
