Roosters really do know what time it is

My rooster Artemis announcing the start of day 

Normally, at 4am like clock-work, I'm awakened by Artemis announcing the start of another day. In summer it can be as early as 3am! This sets off ALL Solly's roosters and I can assure you, NOTHING can sleep through that racket! Their crowing has now set MY internal clock and I'm normally awake just before the crowing starts.

The rooster's morning cock-a-doodle-doo is driven by an internal clock, finds new research, suggesting that male chickens really know the time of day.

The study, detailed in the journal Current Biology, found that roosters put under constant light conditions will still crow at the crack of dawn.

Past studies have found that a myriad of animal behaviors are driven by an internal clock: at night, a dip in insulin causes humans to process food more slowly, and even blind cave fish use a circadian clock to tell time.

"Cock-a-doodle-doo' symbolizes the break of dawn in many countries," said study author Takashi Yoshimura of Nagoya University, in a statement. "But it wasn't clear whether crowing is under the control of a biological clock or is simply a response to external stimuli."

Because stimuli throughout the day — such as car headlights — will set off a rooster's crow at any time, it was also possible that increasing light was the trigger for the cock's crows.

To find out Yoshimura and his colleagues put 40 roosters in a setting with constant light, then recorded when they crowed.

Sure enough, the chickens crowed at daybreak regardless of the light conditions. The roosters also crowed at other times of day and in response to light and the crows of their fellow chickens, but those behaviours were much stronger at daybreak. The findings suggest that an internal circadian clock, rather than external conditions, drive the behavior.

Sometimes, do nothing

A simple life has a different meaning and a different value for every person. For me, it means eliminating all but the essential, eschewing chaos for peace, and spending my time doing what’s important to me.

It means getting rid of many of the things you do so you can spend time with people you love and do the things you love. It means getting rid of the clutter so you are left with only that which gives you value.

Albert Einstein said, "Look deep into nature, and then you will understand everything better." Nature does no more or no less than what is necessary. Minimalist living helps create a simple, inspired and uncomplicated life.

In our daily lives, we often rush through tasks, trying to get them done, trying to finish as much as we can each day. We surround ourselves with more and more stuff and our lives become way too full.

It doesn’t have to be that way. It’s possible to live a simpler life by just sitting back and deciding what is important to you and concentrate solely on that. Sometimes, do nothing.

Farm Talk - Robin vs Wagtail

Camera: Fuji FinePix 2800ZOOM

I posted this article before, in Sept 2008, don't know how many people would go that far back in the archives, but at the moment I've got a very similar scenario going on between my Robins and Cape Wagtails, vying for the best nesting spot in my Fan Palm tree, so I thought I would just publish it again. Luckily, as yet, there have been no fatalities so I'm hoping they'll be able to sort out their differences.

Up until the end of April 2003, we had lived on our smallholding (8,5ha) in Tarlton since 1975. Over the years, I had established a lush garden with numerous indigenous trees and various types of ivies, one of which covered the kitchen wall on the South side of the house and in which the Wagtails made their home. I also had a resident pair of Cape Robins, nesting in the ivy creeping up a dead tree trunk opposite the Wagtails. I dearly loved my Cape Robins, who would take mince out of my hands at the kitchen window, but I must inform you that they are utter terrorists as far as the Wagtails are concerned!

Over a period of 2 weeks, I watched in fascination as both the Robin and Wagtail parents fed their chicks. (After a long, careful search I located the Wagtail nest in the ivy on the kitchen wall – the Robins’ nest was much lower opposite them and more obvious). Both sets of parents scurried hurriedly for the available cache of insects and the Robins, who would dive-bomb and chase them at every opportunity, constantly harassed worms, with one hitch – the Wagtails.



Then, one morning, I heard the Wagtails’ panicky cries and to my utter horror, found the Robin plucking the Wagtail chicks from their nest, dropping them, bleeding and fatally injured. The gentler Wagtails could do nothing but scurry helplessly about. I tried to rescue the unfortunate Wagtail chicks, but to no avail – they were already dying.

The only conclusion I could come to was that the Robins regarded the kitchen window and my mince meals as their domain and begrudged the Wagtails being anywhere in the vicinity!

August inspiration

At no time is Winter more spectacular in South Africa than when the Aloes start flowering in July or August. Then the grey winter is forgotten as bright bursts of orange colour gardens and the country-side, drawing nectar feeders like the Amethyst Sunbird, bees and wasps. My Aloe ferox was lucky to escape the onslaught of any frost this year, providing much-needed sustenance for the birds at the end of winter.

Gardening with "living fossils"

Long before mankind started gardening, Mother Nature was already growing gardens of her own.

By growing these ancient plants, even today we can create a garden reminiscent of a time when dinosaurs ruled the animal kingdom and the dominant plant types ruling the plant kingdom were cycads and ferns.

My Cycad - Cycas revoluta (sago palm, king sago, sago cycad, July 2013 

The Sago Palm is native to the Far East and the cold hardy Sago Palm has been used as a choice container and landscape plant for centuries. The growth habit of Cycas revoluta displays an upright trunk with a diameter from 1" to 12" depending on age, topped with stiff feather-like leaves growing in a circular pattern.

Regardless of age or size, the Sago palms (Cycas revoluta) are one of the easiest plants to grow and care for, indoors or out, by beginner or expert. Sago Palm plants adapt to a wide range of temperatures from 15 to 110 degrees F (-11 to 42 degrees C), Sagos accepts full sun or bright interior light, thrive with proper care and maintenance, and tolerates neglect. In addition, Cycads are extremely long-lived.

My Cycad Cycas revoluta when planted in 2007

Cycads are often referred to as “living fossils” because they date back to the age of dinosaurs of which only fossils remain today. Some scientists believe cycads date back as far as 250 million years, but reached dominance about 150 million years ago - widely known as the age of dinosaurs. During this period they were a prominent component of the earth’s vegetation and a very important part of most herbivores’ diets.

Cycads are arranged into numerous families and genera. Most southern African cycads belong to the genus Encephalartos in the family Zamiaceae. This is said to be the second largest genus of cycads and consists, to date, of about 63 living species. They are all endemic to the continent of Africa.

 My Cycad Cycas revoluta almost two years later in 2009

Cycads are slow growers and therefore need time and patience to grow. They can prove difficult in some instances and may require a little more effort to grow successfully, but they are well worth the time and effort spent on them.

Cycads do best in areas with a moderate climate. Certain species however prefer tropical to subtropical areas and there are a few that are able to survive in cold, dry areas. Extreme climates with prolonged periods of intense heat or cold are not suitable, unless the cycads are in greenhouses where the conditions are controlled.

My Cycad Cycas revoluta in 2010

The basic requirements to grow cycads are: unimpeded soil drainage, good soil, warmth and plenty of water. Your pH should be neutral to slightly alkaline, not acidic. I know that my soil is slightly alkaline, as most of my nearby hydrangeas are pink, the colour of which is caused by alkalinity in the soil. They are sun loving, although some forest species requires some shade.

 

My Cycad in 2012

The Sago Palm growth rate is extremely slow and are extremely long lived and old specimens can grow in curious ways. Many Sago have multi-trunks and multiple branches.

Uses and cultural aspects
In the past, the pith from the stem of cycads was removed, then enclosed in an animal skin, fermented and ground into a meal which was used to make bread. Hence the Afrikaans name of broodboom.

Serval (Stenostira scita)

Photograph: Roelof van der Breggen 

The Walter Sisulu Botanical Garden in Roodepoort (Gauteng, South Africa), in cooperation with the Endangered Wildlife Trust, the North West Province through the Department of Economic Development, Environment, Conservation and Tourism as well as Gauteng Nature Conservation, have embarked on a pioneering camera-trap project to capture images of largely nocturnal animals in the wilderness/natural area of the Garden. High tech infra-red cameras are used to reveal what goes on in the animal world under the cover of darkness.

A Serval cat was the first animal to be recorded through this technology in the Garden and, according to Dr Harriet Davies-Mostert, Head of Conservation Science at Endangered Wildlife Trust, this is the first sighting of this cat species in Gauteng!

This project would later be rolled out to a wider area in the western parts of Gauteng towards North West. It would greatly assist in monitoring the extent and number of some threatened animal species that have been thought to be extinct in the area.

This Botanical Garden was founded in 1982, but has been a popular venue for outings since the 1800's. The Garden has been voted the best place to get back to nature in Gauteng for 9 years in a row and is one of my favourite places to regularly visit.

The natural vegetation of the area is known as the 'Rocky Highveld Grassland' and consists of a mosaic of grassland and savannah, with dense bush in kloofs and along streams. The variety of habitats accommodates over 600 naturally occurring plant species.

A breeding pair of majestic Verreaux's Eagles nest on the cliffs alongside the waterfall. The Garden is home to an abundance of wildlife with over 220 birds species recorded on site. There are also a number of reptiles and small mammals, including small antelope and jackals, which occur naturally in the Nature Reserve.

A Serval is a medium-sized, slender, African wild cat with long legs and a fairly short tail. It is nocturnal and hunts mostly at night, unless disturbed by human activity or the presence of larger nocturnal predators. Although it is specialized for catching rodents, it is an opportunistic predator whose diet also includes birds, hares, hyraxes, reptiles, insects, fish, and frogs. DNA studies have shown that the serval is closely related to the African golden cat and the caracal.

They are commonly found in savannah where there is plenty of water and they occur in most parts of Africa, with the exception of Central Equatorial Africa, the very southern part of the continent, and the Sahara region. These cats prefer bushy areas, tall grass and dry reed beds near streams and are also found on high altitude. They can live up to 20 years in captivity according to some sources. Servals’ spotted coats are sometimes marketed as young leopards or cheetahs and can attract a hearty price on the black market. This, as well as the Serval’s tendency to attack poultry, makes it a target for hunters. Consequently they are no longer found in heavily populated areas, yet, as nocturnal animals, they may still be around though not in greater numbers.

Coffee, Mollie and frugality

It's a sunny winter's day but there is an icy wind blowing. And yet I'm sitting outside in the garden having coffee. Braving the cold. And the reason, you might ask?

Well, I spotted Mollie, my resident Mole Snake, just as she made her way down a hole against the wall. I haven't seen her for months and I'm very keen to get a couple of photographs and also to see whether she has grown at all. The skin she shed just a few months ago panned out at almost two meters (which means she's about 1.3m-1.5m in length as the shed skin is always longer) and the length that disappeared down the hole looked considerably longer. Maybe it's somebody else, so I'm waiting to see. But I don't think I've got much hope of that, she's probably settled in there for the day now.

While I was waiting, I did a couple of chores - filled the seed house with a new block of seeds, filled the nectar bottle with sugar water and watered a few plants, all the while keeping an eye on the hole in case Mollie surfaced. 

 Seed Tower in my garden

I purchased this feeder from a lovely garden shop in Ballito in the "Sage" shopping centre and they have the most exquisite plants, pots and bird paraphernalia. All I need to do now is buy the blocks of replacements seeds which I can do on-line, no need to drive 600km to the coast!

 Nectar feeder

I  also filled up my pine cones with fresh peanut butter sprinkled with some wild bird seed. This is a delicacy that the birds really love.

I'm not having much luck with my Suet feeder - the birds don't seem to want to have anything to do with it! So I break out pieces, place it on one of the bird tables and then they seem to lap it up. but I'm giving it some more time, patience, patience!

I saw a really cool idea on the internet the other day - a raffia bag filled with feathers from which your garden birds can easily pluck some ready-made nesting material. I've made one out of an empty orange bag but have not yet managed to collect enough soft feathers from the garden to fill it with. Moulting season for the chickens is finished for the moment. And I really don't know of anywhere where one can buy feathers from. Maybe a hobby shop...? (I'm also just thinking, why didn't I just buy it when I saw it! But that leaves no space for creativity and frugality, does it? he he!)
