The first point I will make here is within a descriptive commonly used for ‘artificial daylight’ lighting. Sadly, there remains some confusion within the term ‘full-spectrum’. The term full-spectrum is commonly used to denote the emission of a lamp that includes the ‘full-spectrum’ of visible light from 400-700nm and within the wide tolerance used to describe a colour of daylight (Kelvin scale). This can be from 4200-7000 Kelvin or even in cases, 8k kelvin (warm to cool light).
The problem here is, that the term full spectrum is used to describe all light sources and colours within the accepted colours of daylight. There is no accepted standard to be worked within in order to ensure that a lamp does indeed include the spectrum of natural daylight. Therefore, lamps are liable to be labelled full-spectrum even though they may not be. Indeed, a lamp’s output or ‘spectrum’ can be manipulated by lighting scientists to show quite different curves within the lamp’s spectrum away from that of natural daylight.
Currently, it is impossible to accurately mimic the spectrum of the sun in a single lamp, we simply are not able to harness or replicate its true spectral curve yet. What we must do is to use good science to ensure that the spectrum of a lamp mimics that of daylight as closely as possible.
This is still not yet possible in the visible part of the spectrum, however quality lamps that produce UV do so now very accurately. Within this, we can now be sure, that high quality lamps are balanced within the UV portion, project a quantity of UV that can be measured within the international unit of measure ‘UV Index’ and will have a positive impact on the biological cycles that are impacted by UV, especially the D3 cycle.

Parrot language issue
Puerto Rico’s endangered parrots are facing a new threat to their survival – their strange squawks. In a phenomenon never seen before, Puerto Rican parrots bred in captivity, with a view to being released into the wild, were communicating with a different dialect to the wild populations.
Regent parrots thriving in SA wetland
Passion drips from Tim Field’s every word when he speaks about eastern Regent Parrots. The wetland manager at Banrock Station in South Australia is, it’s fair to say, smitten with these striking birds. “September and October is Regent Parrot survey time,” Tim says, “So we’re up well before dawn to make sure we’re at the wetland’s to track the fly-in, fly-out breeding population.”
Landmark event for Philippine Cockatoo
Exciting news has recently arrived of a landmark event in the Philippine Cockatoo Conservation Program (PCCP), the long-term endeavour to bring about the recovery of this ‘Critically Endangered’ species endemic to the Philippines. For the first time ever, a Philippine Cockatoo rescued from the wild, and subsequently released back to its original site, has been recorded to breed and produce a healthy hatchling. Such rescue and release to augment the wild population is just one of a raft of conservation measures conducted by the PCCP and supported by the Loro Parque Fundación over many years.
Increasing Knowledge of the Most Endangered Parrots
Fifty years ago our knowledge of the status of parrots in the wild was limited. Few parrot species were known to be in danger of extinction and these were mainly Amazona parrots which were confined to small islands. At that time very few species had been studied in the wild.
Coronavirus threat to PNG's animal rescue centre
Port Moresby is the capital of Papua New Guinea and is home to its unique animal rescue centre that is now facing the threat of the Covid-19 pandemic, and could be shut down. Papua New Guinea is the most populous nation in Melanesia and faces a potentially devastating wave of Covid-19 infections.
Cucurbitaceae enrichment for our parrots
The group of cucurbitaceae is the one that includes cucumbers and pumpkins. Climbing or creeping plants that usually cover large areas to produce fruits that usually accumulate a lot of water. In nature, these plants defend themselves with a very bitter substance called cucurbitacin.
Rare macaw refuge destroyed
A rare bird sanctuary in Brazil, which is home to 15 per cent of the world’s population of Hyacinth and Lear’s Macaws, has been destroyed by fires, and there are now fears for the survival of these blue macaws. “It is very sad to see decades of my family’s work, years taking care and preserving nature, for this to happen,” said Ana Maria Barreto, owner of the São Francisco do Perigara, a cattle ranch and bird sanctuary of more than 61,000 acres in Mato Grosso state.
The value of animals
Children at a nursery and day care facility were delighted to receive a visit from some very special guests. Learning Land in Workington has a range of animals drop by, as part of an educational encounter paid for by the Co-op. The store has been working with animal specialists, Pet Encounter Cumbria, based in Workington, to deliver therapeutic and educational visits to children and the elderly.
Complete Psittacine Subtle Secrets for Feeding Psittacines – and Getting them to Eat
I have been daily feeding psittacines for 40 years now and there have been times in the past when I felt that was all I did each day – pets, breeders, babies, the birds at the shoppe in Santa Fe. The good news is this has taught me a whole lot about how to do it. And across all species groups, there are some really good guidelines for what to feed, when to feed, and how to make sure your parrots are actually consuming what you are giving them.
Calabash for parrots
Different types of calabash has grown this year very well within our organic crops and a big advantage for our parrots that are relishing every moment during this season.
